Climatic Impacts of Wind Power. Lee M. Miller, David W. Keith. Joule, October 04, 2018, DOI:https://doi.org/10.1016/j.joule.2018.09.009
Highlights
• Wind power reduces emissions while causing climatic impacts such as warmer temperatures
• Warming effect strongest at night when temperatures increase with height
• Nighttime warming effect observed at 28 operational US wind farms
• Wind's warming can exceed avoided warming from reduced emissions for a century
Summary: We find that generating today's US electricity demand (0.5 TW e) with wind power would warm Continental US surface temperatures by 0.24°C. Warming arises, in part, from turbines redistributing heat by mixing the boundary layer. Modeled diurnal and seasonal temperature differences are roughly consistent with recent observations of warming at wind farms, reflecting a coherent mechanistic understanding for how wind turbines alter climate. The warming effect is: small compared with projections of 21st century warming, approximately equivalent to the reduced warming achieved by decarbonizing global electricity generation, and large compared with the reduced warming achieved by decarbonizing US electricity with wind. For the same generation rate, the climatic impacts from solar photovoltaic systems are about ten times smaller than wind systems. Wind's overall environmental impacts are surely less than fossil energy. Yet, as the energy system is decarbonized, decisions between wind and solar should be informed by estimates of their climate impacts.

Child Care Tax Credits: substantial pass-thru, over half of every dollar is passed through to care providers in the form of higher prices and wages
Give Credit Where?: The Incidence of Child Care Tax Credits. Luke P. Rodgers. Journal of Urban Economics, https://doi.org/10.1016/j.jue.2018.10.002
Abstract: The cost of child care can affect a family’s employment, location, and commuting decisions. Child care tax credits are intended to relieve the financial burden of child care for working families, yet the benefit incidence may fall on child care providers if they increase prices in response to credit generosity. Using policy-induced variation in the Child and Dependent Care Credit, this paper presents evidence of substantial pass-through: over half of every dollar is passed through to providers in the form of higher prices and wages. Increased non-refundable credit generosity may have the unintended effect of making child care less affordable for low-income families, a result with distributional and spatial implications due to income sorting of families within an urban area.

The One Percent in New Zealand more strongly legitimize the political & economic systems in society, express lower support for redistributive taxation; & report higher life satisfaction, self-esteem & belongingness compared to everyone else
The Political Attitudes and Subjective Wellbeing of the One Percent. Nikhil K. Sengupta, Chris G. Sibley. Journal of Happiness Studies, https://link.springer.com/article/10.1007/s10902-018-0038-4
Abstract: In capitalist societies, individuals who occupy the highest positions in the economic hierarchy feature prominently in the political discourse under the moniker of the One Percent. However, little is known about how the psychology of One Percent might differ from that of the average person. Using a large, nationally representative sample in New Zealand (N = 14,650), we aimed to fill this gap examining the political attitudes and subjective wellbeing of the top one percent of the income distribution. We found that, compared to general public, the One Percent in New Zealand more strongly legitimize the political and economic systems in society, and express lower support for redistributive taxation. They also report higher life satisfaction, self-esteem and belongingness compared to everyone else. Thus, the One Percent benefit not only economically and politically from the current system, but also psychologically. Moreover, their political beliefs serve to bolster the inequality from which they benefit.

“We are the 99%”—the rallying cry of the Occupy Wall Street movement—was a call for society to unite against the disproportionate power of a small group of economic elites: The One Percent (Occupy Wall Street 2011). This moniker of the One Percent has now entered the lexicon and become a prominent feature of the political discourse on inequality in Western democracies (e.g., The Equality Trust 2017; Carroll and Kertscher 2016). The people to whom this label is applied are argued to be using their influence to bend policy to their own ends, subverting the democratic process (e.g., Stilgitz 2011).
However, these arguments are currently being made in the absence of data about the how the political psychology of individuals that constitute this group might differ from that of the average person. We know very little about how the One Percent view the political and economic systems under which they live, or how they feel about redistributive policies designed to reduce inequality. These are important gaps because claims about how the One Percent exercise their power depend upon claims about their political attitudes as a group (see Gilens 2005). We aim to fill these gaps by comparing the political attitudes of the One Percent in New Zealand to the general population, using a large, representative sample (N = 14,650; see Table 1 for a comparison between New Zealand’s One Percent and the One Percent in other major economies).

How cohabitation, marriage, separation, and divorce influence BMI: The benefits of marriage or cohabitation do not necessarily include a healthier BMI
Mata, J., Richter, D., Schneider, T., & Hertwig, R. (2018). How cohabitation, marriage, separation, and divorce influence BMI: A prospective panel study. Health Psychology, 37(10), 948-958. dx.doi.org/10.1037/hea0000654
Objective: This study examines how changes in cohabitation or marital status affect Body Mass Index (BMI) over time in a large representative sample.
Method: Participants were 20,950 individuals (50% female; 19 to 100 years), representative of the German population, who provided 81,926 observations over 16 years. Face-to-face interviews were used to obtain demographic data, including cohabitation and marital status, height, body weight, and weight-relevant behaviors (exercise, healthy eating, and smoking). Control variables included age, notable changes in status (life events such as having children or change in employment status), perceived stress, and subjective health.
Results: Cohabitation led to significant weight gain in men and women—after four years or longer, about twice the gain associated with marriage (controlling for weight-related behaviors, age, children, employment, stress, and health). BMI after separation was largely comparable to BMI before starting cohabitation; women lost some weight in the first year, men gained some weight after four or more years of separation. Divorce generally predicted weight gain. Changes in exercise, healthy eating, and smoking did not attenuate the effect of changes in relationship status on BMI.
Conclusions: This is among the first longitudinal studies to directly compare the effects of key changes in relationship status on BMI. The findings extend and qualify previous results by showing that the benefits of marriage or cohabitation do not necessarily include a healthier BMI. They also suggest that relationship transitions—particularly moving in with a partner and divorce—may be important time windows for weight gain prevention.

A Reanalysis of Creativity & Religiosity: Creativity & religiosity have a negative relationship in terms of people's attitudes & values toward creativity as well as their perceptions of environment for creativity
Creativity and Religiosity: A Reanalysis with Regional Predictors. Selcuk Acar, Mark A. Runco & Uzeyir Ogurlu. Creativity Research Journal, Volume 30, 2018 - Issue 3, Pages 316-321, https://doi.org/10.1080/10400419.2018.1488349
Abstract: Building on previous research showing a negative relationship between conservatism and creativity, the present investigation focused specifically on religiosity in the context of the United States. Because of the association between conservatism and religiosity, creativity might have a negative association with religiosity, too. To this end, individuallevel and regional data were matched by linking responses to psychometric measures such as Attitudes and Values toward Creativity to regional data such as church attendance. These analyses controlled other regional variables including education, diversity, and socio-economic status. Two-level analyses with individual data at Level 1 and county data at Level 2 indicated that people from more religious locations held less positive attitudes and values toward creativity and rated their environment as less creative. On the other hand, creative personality, ideational behavior and creative achievement were not significantly related to religiosity. Those analyses provided evidence that creativity and religiosity have a negative relationship in terms of people's attitudes and values toward creativity as well as their perceptions of environment for creativity. Findings were discussed in terms of types of religiosity and other socio-cultural variables.

Creativity plays an irreplaceable role in economic and technological development. It seems that religion has a negative association with creativity. If it is true, how can we interpret the rapid development of human society with religious believers comprising 81% of global population? Based on the datasets of the World Values Survey and the Global Creativity Index, this study examined the effects of different religions/denominations on national creativity, and the moderation effect of gross domestic product per capita (GDPpc) in 87 countries. The results showed that: (1) religiosity was negatively associated with creativity at national level; (2) Proportions of Protestant and Catholic adherents in a country were both positively associated with national creativity, while proportion of Islam adherents was negatively associated with national creativity; (3) GDPpc moderated the relationships of creativity with overall religiosity, proportion of Protestant adherents, and proportion of Catholic adherents. In countries with high GDPpc, national religiosity and proportion of Islam could negatively predict national creativity, and proportion of Protestants could positively predict national creativity; in countries with low GDPpc, these relationships became insignificant. These findings suggest that national religiosity hinders creativity to a certain extent. However, some denominations (i.e., Protestant and Catholic) may exert positive influences on creativity due to their religious traditions and values. The religion–creativity relationship at national level only emerges in affluent countries.

On the Necessity of Consciousness for Sophisticated Human Action
On the Necessity of Consciousness for Sophisticated Human Action. Roy F. Baumeister et al. Front. Psychol., October 8 2018, https://doi.org/10.3389/fpsyg.2018.01925
Abstract: In this essay, we aim to counter and qualify the epiphenomenalist challenge proposed in this special issue on the grounds of empirical and theoretical arguments. The current body of scientific knowledge strongly indicates that conscious thought is a necessary condition for many human behaviors, and therefore, consciousness qualifies as a cause of those behaviors. We review illustrative experimental evidence for the causal power of conscious thought while also acknowledging its natural limitations. We argue that it is implausible that the metabolic costs inherent to conscious processes would have evolved in humans without any adaptive benefits. Moreover, we discuss the relevance of conscious thought to the issue of freedom. Many accounts hold conscious thought as necessary and conducive to naturalistic conceptions of personal freedom. Apart from these theories, we show that the conscious perception of freedom and the belief in free will provide sources of interesting findings, beneficial behavioral effects, and new avenues for research. We close by proposing our own challenge via outlining the gaps that have yet to be filled to establish hard evidence of an epiphenomenal model of consciousness. To be sure, we appreciate the epiphenomenalist challenge as it promotes critical thinking and inspires rigorous research. However, we see no merit in downplaying the causal significance of consciousness a priori. Instead, we believe it more worthwhile to focus on the complex interplay between conscious and other causal processes.

Significant social change often comes from the unleashing of hidden preferences; it also comes from the construction of novel preferences
Sunstein, Cass R., Unleashed (August 22, 2017). http://dx.doi.org/10.2139/ssrn.3025749
Abstract: Significant social change often comes from the unleashing of hidden preferences; it also comes from the construction of novel preferences. Under the pressure of social norms, people sometimes falsify their preferences. They do not feel free to say or do as they wish. Once norms are weakened or revised, through private efforts or law, it becomes possible to discover preexisting preferences. Because those preferences existed but were concealed, large-scale movements are both possible and exceedingly difficult to predict; they are often startling. But revisions of norms can also construct rather than uncover preferences. Once norms are altered, again through private efforts or law, people come to hold preferences that they did not hold before. Nothing has been unleashed. These points bear on the rise and fall (and rise again, and fall again) of discrimination on the basis of sex and race (and also religion and ethnicity). They also help illuminate the dynamics of social cascades and the effects of social norms on diverse practices and developments, including smoking, drinking, police brutality, protest activity, veganism, drug use, crime, white nationalism, “ethnification,” considerateness, and the public expression of religious beliefs.

Re “Masturbation: Scientific Evidence and Islam’s View”: Evidence to support a negative relationship between masturbation & health was not scrutinized, & evidente to support or a non-negative relationship was largely ignored
Response to “Masturbation: Scientific Evidence and Islam’s View”. David Speed, Ryan T. Cragun. Journal of Religion and Health, https://link.springer.com/article/10.1007/s10943-018-0627-x
In a recent article entitled, “Masturbation: Scientific Evidence and Islam’s View”, the author Hoseini (2017) set out to discuss the harmful effects of masturbation and how it was prohibited within Islam. Generally, Hoseini’s arguments appeared to have started with a conclusion rather than arriving at one based on all of the available data. Overall, Hoseini’s argumentation suffered from three recurring issues: (1) Masturbation was inexplicably portrayed as deviant; (2) Evidence to support a negative relationship between masturbation and health was not scrutinized; (3) Evidence to support a non-negative relationship between masturbation and health was largely ignored. Each of these points will be addressed in turn.

Sex differences in adolescent physical aggression: Evidence from sixty‐three low‐and middle‐income countries: Sex differences in physical aggression decrease as societal gender inequality increased
Sex differences in adolescent physical aggression: Evidence from sixty‐three low‐and middle‐income countries. Amy Nivette, Alex Sutherland, Manuel Eisner, Joseph Murray. Aggressive Behavior, https://doi.org/10.1002/ab.21799
Abstract: A great deal of research shows that adolescent and adult males are more likely to engage in physical aggression and violence than females are. However, few studies have examined cross‐cultural variation in sex differences, particularly among low‐ and middle‐income countries [LMICs]. Based on social role and sexual selection theories, we derived two hypotheses regarding possible variations in sex differences across societal contexts: 1) sex differences increase with societal gender polarization (social role theory) and 2) sex differences are exacerbated in societies where socio‐economic opportunities are scarce, unequal, or insecure (prediction derived from sexual selection theory). The current study examined the prevalence of and variation in sex differences in physical aggression, as measured by frequent fighting, among 247,909 adolescents in 63 low‐ and middle‐income countries. The results show that, overall, males were over twice as likely (OR = 2.68; 95% CI = 2.60–2.76) to report frequent fighting in the past 12 months than females. However, sex differences vary significantly across LMICs, wherein countries with higher female prevalence rates have smaller sex differences in frequent fighting. Contrary to expectations derived from social role theory, sex differences in physical aggression decrease as societal gender inequality increased. In regards to sexual selection theory, we find no evidence that sex differences in frequent fighting varies according to societal rule of law or income inequality.

How people psychologically manage violations to the belief that the world is fair and just: people generally believe in karmic retribution
Just world violations prompt beliefs in karmic retribution. Jack McDonald. Thesis for M.S., University of Illinois at Urbana-Champaign. http://hdl.handle.net/2142/101488
Abstract: How likely are people to think that someone who perpetrates a crime against another person will experience an adverse event in response? In other words, how much do people believe in karmic retribution? Across three studies, we examined this question in the present research. Participants were randomly assigned to read about a sexual crime that varied in its level of severity (e.g., a man whistles suggestively at a woman vs. a man takes an up-skirt photo of a woman). People who read about more severe crimes thought that a negative event would be more likely to happen to the offender of the crime. Importantly, people thought negative events were more likely to affect offenders of severe crimes even when the event was entirely unrelated to the crime (e.g., getting hit by a car after assaulting a woman), and even if a person did not intentionally create the adverse event (e.g., getting cancer). Dispositional belief in a just world did not consistently moderate the effect of crime severity on the likelihood of negative events. These findings provide novel evidence for the question of how people psychologically manage violations to the belief that the world is fair and just, and provide empirical support that people generally believe in karmic retribution.

Are Tinder & Dating Apps Changing Dating & Mating? More than 80% of unpartnered heterosexual adults have not gone on any dates or met any new people in the past 12 months; being unpartnered is more stable that thought
Are Tinder and Dating Apps Changing Dating and Mating in the USA? Michael Rosenfeld. Families and Technology, National Symposium on Family Issues book series, volume 9, pp 103-117. https://link.springer.com/chapter/10.1007/978-3-319-95540-7_6
Abstract: I use in-depth interviews and a new national survey to examine how people use phone dating apps (such as Tinder and Grindr), how often they use them, and why. Gay men are the most active users of the phone dating apps. Unpartnered heterosexual adults do not use phone dating apps very often and meet few new partners through apps. According to the survey data, more than 80% of unpartnered heterosexual adults have not gone on any dates or met any new people in the past 12 months, which suggests that being unpartnered is a more stable status for heterosexual adults than previously thought.

The evolutionary dynamics of adaptive virginity, sex‐allocation, & altruistic helping in haplodiploids: when mating is costly (e.g., when mating increases predation risk), virginity be an adaptive reproductive strategy
The evolutionary dynamics of adaptive virginity, sex‐allocation, and altruistic helping in haplodiploid animals. Petri Rautiala, Heikki Helanterä, Mikael Puurtinen. Evolution, https://doi.org/10.1111/evo.13399
Abstract: In haplodiploids, females can produce sons from unfertilized eggs without mating. However, virgin reproduction is usually considered to be a result of a failure to mate, rather than an adaptation. Here, we build an analytical model for evolution of virgin reproduction, sex‐allocation, and altruistic female helping in haplodiploid taxa. We show that when mating is costly (e.g., when mating increases predation risk), virginity can evolve as an adaptive female reproductive strategy. Furthermore, adaptive virginity results in strongly divergent sex‐ratios in mated and virgin queen nests (“split sex ratios”), which promotes the evolution of altruistic helping by daughters in mated queen nests. However, when helpers evolve to be efficient and increase nest production significantly, virgin reproduction is selected against. Our results suggest that adaptive virginity could have been an important stepping stone on the pathway to eusociality in haplodiploids. We further show that virginity can be an adaptive reproductive strategy also in primitively social haplodiploids if workers bias the sex ratio toward females. By remaining virgin, queens are free to produce sons, the more valuable sex in a female‐biased population. Our work brings a new dimension to the studies linking reproductive strategies with social evolution.

The categorical model of classification in the V edition of the Diagnostic and Statistical Manual of Mental Disorders is problematic; a proposed solution is an empirically based dimensional organization of psychopathology, HiTOP
Personality in a Hierarchical Model of Psychopathology. Thomas A. Widiger et al. Association for Psychological Science, https://doi.org/10.1177/2167702618797105
Abstract: The categorical model of classification in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders is sorely problematic.

Abstract: The categorical model of classification in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders is sorely problematic. A proposed solution is emerging in the form of a quantitative nosology, an empirically based dimensional organization of psychopathology. More specifically, a team of investigators has proposed the Hierarchical Taxonomy of Psychopathology (HiTOP). The purpose of this article is to discuss the potential role, importance, and implications of personality within the HiTOP dimensional model of psychopathology. Suggested herein is that personality provides a foundational base for the HiTOP dimensional model of psychopathology. Implications concern the potential value of the early assessment of and screening for personality as well as the development of protocols for the treatment of personality trait domains, which may in turn contribute to substantial improvements in quality of life as well as mental and physical health.

Chitwan Valley Family Study, Nepal, confirms: Aging adults with more highly educated children experience better health and higher survival; possible mechanisms are older adults' better health behaviors, & their greater support in later life
Offspring education and parental mortality: Evidence from South Asia. Emily Smith-Greenaway, Sarah Brauner-Otto, William Axinn. Social Science Research, Volume 76, November 2018, Pages 157-168. https://doi.org/10.1016/j.ssresearch.2018.07.001
Abstract: Decades of research show that education not only confers individual health benefits, but it also spills over to advantage subsequent generations. More recently, research has confirmed that the intergenerational health benefits of education can also flow upward: aging adults with more highly educated children experience better health and higher survival. Research has documented this finding in high-income settings, and also in select low- and middle-income contexts, raising questions about how having an adult child who attended relatively low levels of education can benefit aging parents' well-being. In this study, we use multilevel, long-term panel data on a cohort of older adults from the Chitwan Valley Family Study in rural Nepal to establish whether the association between offspring education and parents' survival is observable in this extremely poor, agrarian context. Extending past studies, we then leverage additional data on older adults to examine the association between offspring education and two theorized mechanisms: older adults' better health behaviors and their greater support in later life.

Black-white differences in happiness, 1972–2014
Black-white differences in happiness, 1972–2014. John Iceland, Sarah Ludwig-Dehm. Social Science Research, https://doi.org/10.1016/j.ssresearch.2018.10.004
Abstract: This paper examines the extent to which the black-white gap in happiness—an important indicator of subjective well-being—has narrowed over the 1972 to 2014 period. Analyzing data from the General Social Survey, we find that that the difference in levels of happiness between whites and blacks is substantial, but declined over time. Results from a decomposition analysis shed new light on the sources of change. We find that observable differences in characteristics of whites and blacks explain a significant and growing proportion of the happiness gap. The two most important characteristics are income and marital status, as both are strongly associated with race and happiness, and the proportion of the difference in the gap that they explain has generally increased over time. Overall, the declining gap in happiness is consistent with the moderate narrowing of substantial racial disparities in other realms, such as life expectancy, residential segregation, and neighborhood conditions, suggesting small steps toward equality in some realms, even as high levels of inequality persist in others.

Internalised White Ideal, Skin Tone Surveillance, and Hair Surveillance Predict Skin and Hair Dissatisfaction and Skin Bleaching among African American and Indian Women
Internalised White Ideal, Skin Tone Surveillance, and Hair Surveillance Predict Skin and Hair Dissatisfaction and Skin Bleaching among African American and Indian Women. Kathryn Harper, Becky L. Choma. Sex Roles, https://link.springer.com/article/10.1007/s11199-018-0966-9
Abstract: Women of Colour are subject to unique pressures regarding their appearance due to racialised beauty standards and the pre-eminence of White features (e.g., skin tone and hair texture). Through associated self-objectification, Women of Colour can face negative outcomes, including negative thoughts and feelings about body features, and can engage in potentially dangerous behaviours like skin bleaching. The present research investigated the connection between internalisation of White beauty standards and Women of Colour’s dissatisfaction with their skin and hair as well as their use of cosmetic products to attempt to meet White beauty ideals. Participants were 149 African American women from the United States and 168 Indian women living in India. Results reveal that internalisation of White beauty ideals predicted skin tone and hair texture dissatisfaction as well as skin bleaching. Results also suggest that these associations are indirectly mediated by surveillance of skin tone and hair texture. Findings are discussed in relation to self-objectification theory and representations of racialised beauty standards. These findings suggest that in order to reduce the negative effects of internalisation of White ideals on Women of Colour, White standards of beauty ought to be targeted and dismantled. Broadening of beauty standards and increasing positive media representations of Women of Colour may also be important.

How Does Traditional Masculinity Relate to Men and Women’s Problematic Pornography Viewing?
How Does Traditional Masculinity Relate to Men and Women’s Problematic Pornography Viewing? Nicholas C. Borgogna et al. Sex Roles, https://link.springer.com/article/10.1007/s11199-018-0967-8
Abstract: Problematic pornography viewing (PPV) is a growing concern. Based on a masculine gender role strain framework, individuals endorsing traditional masculinity ideology (TMI) may be especially drawn to pornography. However, relatively few studies have explored how TMI is related to PPV. Furthermore, no known studies have explored how these connections differ in men and women. To address these gaps, we conducted a large survey of 310 men and 469 women in the United States assessing multiple PPV and TMI dimensions. A bifactor structural equation model was used to regress PPV domains onto global and specific TMI factors. Invariance testing further examined the moderating effects of participants’ gender in the model. Results indicated that global TMI was unrelated to men’s PPV. However, men’s dominance ideologies predicted greater functional problems and excessive pornography use. Men’s restrictive emotionality and heterosexist ideologies predicted control difficulties with pornography use and using pornography to escape negative emotions. Additionally, men’s avoidance of femininity ideology predicted excessive pornography use and control difficulties. For women, only global TMI was associated with functional problems. Invariance testing suggested the observed gender differences were not due to underlying discrepancies in the measurement of TMI or PPV. Clinical interventions for PPV that incorporate gender role themes are recommended.

The ecological and evolutionary significance of Neanderthal healthcare: Care for the ill & injured is likely to have a long evolutionary history & to have been highly effective in improving health & reducing mortality risks
Living to fight another day: The ecological and evolutionary significance of Neanderthal healthcare. Penny Spikins et al. Quaternary Science Reviews,
https://doi.org/10.1016/j.quascirev.2018.08.011
Highlights
• In the Neanderthal ecological niche mortality risks from injuries were typically high.
• Neanderthal record of care practices is biased towards severe cases.
• Healthcare appears to have been generally low cost and effective in reducing mortality.
Abstract: Evidence of care for the ill and injured amongst Neanderthals, inferred through skeletal evidence for survival from severe illness and injury, is widely accepted. However, healthcare practices have been viewed primarily as an example of complex cultural behaviour, often discussed alongside symbolism or mortuary practices. Here we argue that care for the ill and injured is likely to have a long evolutionary history and to have been highly effective in improving health and reducing mortality risks. Healthcare provisioning can thus be understood alongside other collaborative ‘risk pooling’ strategies such as collaborative hunting, food sharing and collaborative parenting. For Neanderthals in particular the selective advantages of healthcare provisioning would have been elevated by a variety of ecological conditions which increased the risk of injury as well their particular behavioural adaptations which affected the benefits of promoting survival from injury and illness. We argue that healthcare provisioning was not only a more significant evolutionary adaptation than has previously been acknowledged, but moreover may also have been essential to Neanderthal occupation at the limits of the North Temperate Zone.

Women are more upset by cyber aggression than men; women experience online posts derogating their physical appearance more often than men, while men experience online posts derogating their status more often than women
Wyckoff, J. P., Buss, D. M., & Markman, A. B. (2018). Sex differences in victimization and consequences of cyber aggression: An evolutionary perspective. Evolutionary Behavioral Sciences, http://dx.doi.org/10.1037/ebs0000150
Abstract: Cyber aggression is a pervasive problem, yet evolutionary psychologists have been slow to address this area of research. We utilize an evolutionary perspective to provide a theoretical framework to address research that has found that women are more vulnerable to negative effects of cyber aggression. Studies of intrasexual competition suggest that men and women adopt different strategies to derogate competitors that target fitness-relevant characteristics. We explore the possibility that cyber aggression follows the same principles and propose that sex differences in cyber aggression are more nuanced than previous research suggests. Study 1 replicates the finding of previous research that women are more upset by cyber aggression than men. Study 2 provides qualitative insight into sex differences in content of cyber aggression, demonstrating that women experience online posts derogating their physical appearance more often than men, while men experience online posts derogating their status more often than women. The discussion focuses on future directions for the application of evolutionary psychology to cyber aggression.

Privileged students shouldn’t be allowed to speak in class at all and should just listen and learn in silence; they would benefit from experiential reparations (sitting on the floor, wearing chains, or intentionally being spoken over
The Grievance Studies Scandal: Five Academics Respond. Quillete, October 1, 2018.https://quillette.com/2018/10/01/the-grievance-studies-scandal-five-academics-respond/
Excerpts:
The flagship feminist philosophy journal, Hypatia, accepted a paper (not yet published online) arguing that social justice advocates should be allowed to make fun of others, but no one should be permitted to make fun of them. The same journal invited resubmission of a paper arguing that “privileged students shouldn’t be allowed to speak in class at all and should just listen and learn in silence,” and that they would benefit from “experiential reparations” that include “sitting on the floor, wearing chains, or intentionally being spoken over.” The reviewers complained that this hoax paper took an overly compassionate stance toward the “privileged” students who would be subjected to this humiliation, and recommended that they be subjected to harsher treatment. Is asking people of a certain race to sit on the floor in chains better than asking them to wear a yellow star? What exactly is this leading to?
Now, three academics have submitted twenty spoof manuscripts to journals chosen for respectability in their various disciplines. Seven papers were accepted before the experiment stopped; more are surviving peer review. This new raid on screamingly barmy pseudo-scholarship is the Alan Sokal Opening, weaponised. Like dedicated traceurs in a Parkour-fest, the trio scrambled over the terrain of what they call Grievance Studies. And they dropped fire-crackers. One published paper proposed that dog parks are “rape-condoning spaces.” Another, entitled “Our Struggle is My Struggle: Solidarity Feminism as an Intersectional Reply to Neoliberal and Choice Feminism” reworked, and substantially altered, part of Mein Kampf. The most shocking, (not published, its status is “revise and resubmit”) is a “Feminist Approach to Pedagogy.” It proposes “experiential reparations” as a corrective for privileged students. These include sitting on the floor, wearing chains, or being purposely spoken over. Reviewers have commented that the authors risk exploiting underprivileged students by burdening them with an expectation to teach about privilege.
When I grew up something like the following order of badness prevailed: murder (the worst), followed by serious physical violence, cheating and lying, nasty shouting, nasty speaking and at the milder end, nasty thinking. This has changed. There is evidence that many scholars favour punitive thought-reform.
The dog-park hoax paper, honoured by the journal as exemplary scholarship, contains gems like this: “Dog parks are microcosms where hegemonic masculinist norms governing queering behavior and compulsory heterosexuality can be observed in a cross-species environment.” It looks like a case of reviewers asleep at the wheel.
Occasionally, however, unintentional absurdities of feminist thinking have crept into much better philosophical journals than Hypatia. A good example is an article from the Australasian Journal of Philosophy in which a feminist describes a “phallic drama” involving two statements, p and ~p (the negation of p):
There is really only one actor, p, and ~p is merely its receptacle. In the representation of the Venn diagram, p penetrates a passive, undifferentiated universal other which is specified as a lack, which offers no resistance, and whose behavior it controls completely.
Rolf Degen summarizing: A high sex ratio (scarcity of women compared to men) leads to higher marriage rates, fewer divorces, greater fertility, women choosing higher quality mates & being happier in their marriages
Does Mate Scarcity Affect Marital Choice and Family Formation? The Evidence for New and Classic Formulations of Sex Ratio Theory. Emily A. Stone. Marriage and Family Review, https://doi.org/10.1080/01494929.2018.1501789
Abstract: Guttentag and Secord pioneered research on the social consequences of imbalances in the numbers of men and women—the sex ratio. Since then, sociologists, psychologists, anthropologists, and even biologists have investigated its effects on marriage and reproduction. I review the three prevailing theories to explain why sex ratio should affect marriage and reproduction, along with the evidence that it does. I also review the growing evidence that sex ratio imbalances are associated with mate choice. Sex ratio reveals contradictory relationships with mate preferences and actual partner choice, however, raising a conundrum for future research. Overall, there is strong experimental and correlational support for the patterns of marriage and reproduction associated with sex ratio. What emerges is the necessity for future research to distinguish among the perspectives to explain why.

Optimized technologies emerge through the selective retention of small improvements across generations without requiring explicit understanding of how these technologies work; we don't spontaneously create multidimensional causal theories but instead mainly produce simplistic models
Derex, Maxime, Jean-François Bonnefon, Robert Boyd, and Alex Mesoudi. 2018. “Causal Understanding Is Not Necessary for the Improvement of Culturally Evolving Technology.” PsyArXiv. September 3. doi:10.31234/osf.io/nm5sh
Abstract: Highly-optimized tools are common in traditional populations. Bows and arrows, dogsleds, clothing, houses, and kayaks are just a few examples of the complex, exquisitely designed tools that humans produced and used to colonize new, demanding environments. Because there is much evidence that humans’ cognitive abilities are unparalleled, many believe that such technologies resulted from our superior causal reasoning abilities. However, others have stressed that the high dimensionality of human technologies make them very hard to understand causally. Instead, they argue that optimized technologies emerge through the selective retention of small improvements across generations without requiring explicit understanding of how these technologies work. Here, we find experimental support for the latter view by showing that a physical artifact becomes progressively optimized across generations of social learners in the absence of explicit causal understanding. We find that participants do not spontaneously create multidimensional causal theories but instead mainly produce simplistic models related to a specifically salient dimension. Finally, we show that the transmission of these simplistic theories constrain exploration in subsequent generations of learners and has negative downstream effects on their understanding. These results indicate that highly optimized technologies do not necessarily result from evolved reasoning abilities but instead can emerge from the blind accumulation of many small improvements made across generations linked by cultural transmission, and demand a focus on the cultural dynamics underlying technological change as well as individual cognition.

Of the 56 participants who received a theory... 15 received an inertia-related theory, 17 received an energy-related theory, 6 received a full theory and 18 received diverse, irrelevant theories
...inherited theories strongly affected participant's understanding of the wheel system. Participants who did not inherit any theory (“Configurations” treatment) scored similarly (and better than chance) on questions about inertia and questions about energy (Fig. 3I). In comparison, participants who inherited an inertia- or energy- related theory showed skewed understanding patterns. Inheriting an inertia-related theory increased their understanding of inertia, but decreased their understanding of energy; symmetrically, inheriting an energy-related theory increased their understanding of energy, but decreased their understanding about inertia. One explanation for this pattern is that inheriting a unidimensional theory makes individuals focus on the effect of one parameter while blinding them to the effects of others. However, participants’ understanding may also result from different exploration patterns. For instance, participants who received an inertia-related theory mainly produced balanced wheels (Fig. 3F), which could have prevented them from observing the effect of varying the position of the wheel’s center of mass.
...These results suggest that the understanding patterns observed in participants who received unidimensional theories is likely the result of the canalizing effect of theory transmission on exploration. Note that in the present case, this canalizing effect is performance-neutral: with our 2-dimensional problem, better understanding of one dimension and worse understanding of one dimension simply compensate each other. For a many-dimensional problem, though, better understanding of one dimension is unlikely to compensate for worse understanding of all the others.

Experimental research suggests that high power and leadership result in the experience of more positive and less negative emotions; we don't find relation with power and subjective well-being or job satisfaction
Small and negligible? Evidence on the Relation Between Individuals’ Power in the Job Situation and their Satisfaction with Life and Job. Herbert Bless & Nadia Granato. Basic and Applied Social Psychology, https://doi.org/10.1080/01973533.2018.1510779
Abstract: Experimental research suggests that high power and leadership result in the experience of more positive and less negative emotions. Extending these findings of experimental manipulations, we investigated relations between power and subjective well-being in a representative national survey. Defining power as the capability to administer resources or punishments, we inferred power from the number of people whom respondents supervise in their job. The results reflect a very small relation between this operationalization and individuals’ life and job satisfaction. The results suggest that prior experimental findings on the relation between power and satisfaction judgments cannot be applied directly to job situations.

Working in occupations with higher percentages of male workers is associated with higher levels of unpleasantness and lower levels of meaningfulness at work for women
Men and Women at Work: Occupational Gender Composition and Affective Well-Being in the United States. Yue Qian, Wen Fan. Journal of Happiness Studies, https://link.springer.com/article/10.1007/s10902-018-0039-3
Abstract: Most adults spend almost half their waking hours at work. How people feel during work can have far-reaching consequences for their quality of life. This study traces male and female workers’ affective experiences at work to the gender composition of their occupations. To do this, we draw on nationally representative time diary data on affective experiences at work from the 2010, 2012, and 2013 well-being modules of the American Time Use Surveys, as well as data on occupational gender composition from the Current Population Surveys. Our analytic sample contains 5216 activity records of working at main jobs from 4486 non-self-employed workers. We find significant gender differences in the relationship between occupational gender composition and affective well-being: Working in occupations with higher percentages of male workers is associated with higher levels of unpleasantness and lower levels of meaningfulness at work for women but these associations are not significant for men. We discuss the implications of our findings for gender inequality in work-related well-being and for the stalled progress towards gender integration in occupations.

Before recovering traumatic memories, 10% had attempted/thought about suicide; after, 67%; before, 7% had been hospitalized; after, 37%; before, 3% had engaged in self-mutilation, after, 27%; many remembered being abused in satanic rituals
Invasion of the Mind Snatchers: A Nation Full of Traumatic Memories. Elizabeth F. Loftus, Jennifer Teitcher. Clinical Psychological Science, https://doi.org/10.1177/2167702618797107
Abstract: The new national survey by Patihis and Pendergrast (this issue) suggests that millions of people may have recovered traumatic memories that they spent large parts of their lives not thinking about. We wondered whether they are better off and suggest that more than a few may be worse off rather than better. Given this risk of therapy, should therapists be warning patients of the potential risks before conducting therapy? The answer is not clear as warning about risks can be risky itself. Overall, we propose that with so many people living with “recovered” memories, future research now needs to address whether they are indeed better off and which methods would help achieve that goal.

Dear Abby: Should I Give Advice or Receive It? Lauren Eskreis-Winkler, Ayelet Fishbach, Angela L. Duckworth. Psychological Science, https://doi.org/10.1177/0956797618795472
Abstract: Typically, individuals struggling with goal achievement seek advice. However, in the present investigation (N = 2,274), struggling individuals were more motivated by giving advice than receiving it. In a randomized, controlled, double-blind field experiment, middle-school students who gave motivational advice to younger students spent more time on homework over the following month than students who received motivational advice from expert teachers (Experiment 1). This phenomenon was replicated across self-regulatory domains: Strugglers who gave advice, compared with those who received expert advice, were more motivated to save money, control their tempers, lose weight, and seek employment (Experiments 2 and 3). Nevertheless, across domains, people erroneously predicted the opposite, expecting themselves and others to be less motivated by giving advice than receiving it (Experiments 2 and 3). Why are people blind to the motivational power of giving? Giving advice motivated givers by raising their confidence—a reality that predictors fail to anticipate (Experiment 4).

The language of liberal & conservative extremists was more negative & angry in its emotional tone than that of moderates; contrary to previous research, liberal extremists’ language was more negative than that of conservative ones
Frimer, Jeremy A., Mark J. Brandt, Zachary J. Melton, and Matt Motyl. 2018. “Extremists on the Left and Right Use Angry, Negative Language.” OSF Preprints. October 3. doi:10.31219/osf.io/ufd2s
Abstract: We propose that political extremists use more negative language than moderates. Previous research found that conservatives report feeling happier than liberals and yet liberals “display greater happiness” in their language than do conservatives. However, some of the previous studies relied on questionable measures of political orientation and affective language; and no studies have examined whether political orientation and affective language are non-linearly related. Revisiting the same contexts (Twitter, U.S. Congress), and adding three new ones (political organizations, news media, crowdsourced Americans), we found that the language of liberal and conservative extremists’ was more negative and angry in its emotional tone than that of moderates. Contrary to previous research, we found that liberal extremists’ language was more negative than that of conservative extremists. Additional analyses supported the explanation that extremists feel threatened by the activities of political rivals, and their angry, negative language represents efforts to communicate as much to others.

Scholarly culture: How books in adolescence enhance adult literacy, numeracy and technology skills in 31 societies
Scholarly culture: How books in adolescence enhance adult literacy, numeracy and technology skills in 31 societies. Joanna Sikora, M. D. R. Evans, Jonathan Kelley. Social Science Research, https://doi.org/10.1016/j.ssresearch.2018.10.003
Abstract: A growing body of evidence supports the contention of scholarly culture theory that immersing children in book-oriented environments benefits their later educational achievement, attainment and occupational standing. These findings have been interpreted as suggesting that book-oriented socialization, indicated by home library size, equips youth with life-long tastes, skills and knowledge. However, to date, this has not been directly assessed. Here, we document advantageous effects of scholarly culture for adult literacy, adult numeracy, and adult technological problem solving. Growing up with home libraries boosts adult skills in these areas beyond the benefits accrued from parental education or own educational or occupational attainment. The effects are loglinear, with greatest returns to the growth in smaller libraries. Our evidence comes from regressions with balanced repeated replicate weights estimated on data from 31 societies which participated in the Programme for the International Assessment of Adult Competencies (PIAAC) between 2011 and 2015.

Women: Falling in love is associated with immune system gene regulation; the changes are independent of changes in physical illness or sexual contact, & are consistent with facilitation of sexual reproduction
Falling in Love is Associated with Immune System Gene Regulation. Damian R. Murray et al. Psychoneuroendocrinology, https://doi.org/10.1016/j.psyneuen.2018.09.043
Highlights
• Falling in love is associated with up-regulation of Type I interferon response genes.
• Falling in love is associated with a reciprocal down-regulation of α-defensin-related transcripts.
• These changes are independent of changes in physical illness or sexual contact.
• Changes are consistent with selective up-regulation of innate immune responses to viral infections.
• Changes also consistent with dendritic cell facilitation of sexual reproduction.
Abstract: Although falling in love is one of the most important and psychologically potent events in human life, the somatic implications of new romantic love remain poorly understood. Psychological, immunological, and reproductive perspectives offer competing predictions of the specific transcriptional regulatory shifts that might accompany the experience of falling in love. To characterize the impact of romantic love on human genome function, we conducted genome-wide transcriptome profiling of 115 circulating immune cell samples collected from 47 young women over the course of a 2-year longitudinal study. Analyses revealed a selective alteration in immune cell gene regulation characterized by up-regulation of Type I interferon response genes associated with CD1C+/BDCA-1+ dendritic cells (DCs) and CLEC4C+/BDCA-2+ DCs, and a reciprocal down-regulation of α-defensin-related transcripts associated with neutrophil granulocytes. These effects emerged above and beyond the effects of changes in illness, perceived social isolation, and sexual contact. These findings are consistent with a selective up-regulation of innate immune responses to viral infections (e.g., Type I interferons and DC) and with DC facilitation of sexual reproduction, and provide insight into the immunoregulatory correlates of one of the keystone experiences in human life.

Repeated experiences of rejection result in decreases in ideal standards & self-perceived mate value & increases in ideal flexibility, but there is no increased acceptance
Charlot, Nicolyn, Rhonda N. Balzarini, and Lorne Campbell. 2018. “The Influence of Romantic Rejection on Change in Ideal Standards, Ideal Flexibility, and Self-perceived Mate Value.” PsyArXiv. October 3. doi:10.31234/osf.io/yhvdu
Abstract: Research has shown that ideal romantic standards predict future partner characteristics and influence existing relationships, but how standards develop and change among single individuals has yet to be explored. Using the Ideal Standards Model, the present study sought to determine whether repeated experiences of romantic rejection and acceptance over time influence ideal standards, ideal flexibility, and self-perceived mate value (N = 208). Per expectations, results suggest repeated experiences of rejection result in decreases in ideal standards and self-perceived mate value and increases in ideal flexibility, though no effects emerged for acceptance. Given the predictive nature of ideal standards and the influence rejection has on such, findings from this study contribute to a greater understanding of relationship formation processes.
---
Consistent with hypotheses, increased experiences of rejection predicted decreases in self-perceived mate value and ideal standards, and increases in ideal flexibility over time (H5, H7, H8). This is the first study to empirically support Simpson and colleagues’ (2001) idea that repeated experiences of rejection cause a decline in ideal standards and increases in ideal flexibility. Further, the finding that rejection is associated with lower self-perceived mate value over time is consistent with prior literature showing that rejection decreases self-esteem and self-perceived mate value (Kavanagh et al., 2010; Pass et al., 2010; Ruan & Zhang, 2012; Zhang et al., 2015), but the present study is the first to demonstrate this effect longitudinally. Combined, these findings suggest that repeated experiences of rejection predict changes not only in individuals’ perceptions of themselves, but also what they desire in a romantic partner. This may occur because multiple experiences of rejection repeatedly signal the disinterest of individuals advanced upon, which could cause participants to reevaluate their own worth as potential mates, as well as their standards for the types of people with whom they are likely to enter a relationship. Decreasing standards and increasing flexibility is likely advantageous, as doing so widens the dating pool and leads to an increased chance of experiencing acceptance.
Experiences of acceptance did not predict changes in ideal standards (H6), ideal flexibility, or self-perceived mate value. Although Simpson and colleagues (2001) suggested repeated experiences of acceptance would increase standards, prior literature has demonstrated that acceptance has mixed effects on mate expectations (e.g., Kavanagh et al., 2014; Zhang et al., 2014). Sociometer theory suggests that people should be more attuned to rejection than acceptance (Leary & Baumeister, 2000; Leary & Downs, 1995), as ignoring rejection is costlier than ignoring acceptance, which may further account for these findings. Acceptance may primarily function as a reaffirmation of the status quo, rather than a reason to increase standards. However, the type of person accepting the advance may be influential – repeated experiences of acceptance from potential partners of relatively high mate value may cause an increase in ideal standards and self-perceived mate value, and a decrease in ideal flexibility, while acceptances from similar or lower mate value individuals may not cause changes in these constructs.
Contrary to hypotheses, self-perceived mate value did not moderate rejection’s impact on change in ideal standards, ideal flexibility, or self-perceived mate value (H9, H10, H11). One explanation for the null findings is that high self-perceived mate value is an effective buffer against singular experiences of rejection, but not repeated experiences, as documented in this study. Indeed, sociometer theory suggests that people with high self-esteem should be less attuned to experiences of rejection than those with low self-esteem, but repeated instances of rejection should increasingly trigger the sociometer, thus decreasing self-esteem. Given the close association between self-esteem and self-perceived mate value (Brase & Guy, 2004; Kirkpatrick & Ellis, 2001), this is likely true for self-perceived mate value as well. As the present study examined multiple instances of rejection, any buffering effects initially high self-perceived mate value had may not have been evident after six months of acceptance and rejection experiences. Future research should examine self-perceived mate value as a moderator of both singular and multiple experiences of rejection to explore this notion further.
Gender did not influence many outcomes when included in the primary analyses, although results did indicate that men reported higher numbers of overall, accepted, and rejected advances than women, which is consistent with prior research which shows men tend to initiate more dates and exhibit more direct dating behaviors than women (Eaton & Rose, 2011). Interestingly, gender was a significant moderator in a three-way interaction with initial self-perceived mate value and rejection, such that the ideal standards of women with initially low self-perceived mate value were more impacted by high levels of rejection than women with initially high levels of self-perceived mate value, and men with initially low self-perceived mate value. This finding suggests that the ideal standards of women with low self-perceived mate value are particularly sensitive to experiences of rejection. However, this result should be interpreted cautiously, given that the sample size of this study is lower than ideal for properly detecting a three-way interaction (Heo & Leon, 2010).
Implications
The current study has several theoretical implications. First, the results provide support for certain aspects of the ISM, as ideal standards positively correlated with self-perceived mate value, and ideal flexibility negatively correlated with ideal standards and self-perceived mate value. Additionally, this is the first study to empirically support the notion that repeated experiences of rejection over time decrease ideal standards and self-perceived mate value and increase ideal flexibility. However, the ISM posits that repeated experiences of acceptance will cause the opposite effect from rejection, but the present study did not demonstrate any effects of romantic acceptance. Future researchers using the ISM should take into consideration the relative importance of rejection over acceptance and examine the mechanisms behind this effect. Further, the ISM predicts that ideal flexibility should change more than ideal standards, but support for this prediction was not found in the current study. Furthermore, this study has implications for literature on the mating sociometer, as self-perceived mate value does not appear to moderate the influence of rejection on the aforementioned constructs. However, as mentioned previously, this may be due the present study’s focus on repeated versus singular rejection experiences, so self-perceived mate value’s role as a moderator should be explored further.
The present findings also have implications for relationship initiation and relationship satisfaction. Two longitudinal studies (Campbell et al., 2016; Gerlach et al., 2017) have demonstrated that ideal partner preferences of single individuals are predictive of characteristics of future partners. These findings, combined with the present study’s findings that experiences of rejection impact ideal standards, as well as ideal flexibility and self-perceived mate value, suggests that experiences of rejection while single may influence partner selection. Although future research is needed, these findings suggest that individuals who experience high levels of rejection may lower their ideal standards and enter relationships with partners of lower mate quality than initially desired. Therefore, individuals who change their ideal standards in response to rejection may end up with lower-quality mates than those who do not experience high levels of rejection. Reducing one’s standards and preferences may impact relationship quality, as people who enter relationships with partners who match their new, lower standards may experience less relationship satisfaction than those who enter relationships with partners who match their initial, unadjusted standards.
Limitations and Future Directions
While the present study contributes many novel findings to relationship literature, it does have several notable limitations. First, due to the longitudinal nature of the study, high attrition impacted the quality of data. Specifically, many participants did not complete every monthly survey, so the true number of accepted and rejected advances is unknown. It is possible that some people who were categorized as never having made an advance did make advances but did not fill out surveys for those months. Additionally, while the initial sample included 208 participants, only 95 were used in analyses involving the impact of rejection on change in ideal standards, flexibility, and self-perceived mate value, which is lower than desired. The remaining 113 participants either did not respond to the monthly surveys or did not report making any advances during the monthly surveys. The generalizability of the study is also limited, as the sample is predominantly white, and the sexual orientation of participants is unknown.
Second, the present study’s focus was on experiences of accepted and rejected advances, but it did not account for advances made towards the participants, which may also predict change in standards, flexibility, and self-perceived mate value. Participants who are routinely approached likely have higher ideals and self-perceived mate value, and lower flexibility than those who are never or less frequently approached. The present study also did not account for who participants were approaching. Rejection from a long-time crush may be much more impactful than rejection from a stranger at a bar, or, rejection from an extremely high-quality potential mate may have less of an effect on an individual than rejection from someone of similar or lower mate quality. Additionally, the present research did not inquire about the type of relationship being sought by participants; it is possible that those seeking casual relationships would be less impacted by rejection than those desiring more serious commitments. Further, explicit definitions of accepted and rejected advances were not included in the study, so participants may have had different interpretations of what counted as an accepted or rejected advance, which may have influenced their reports. Ultimately, the present study provides a broad perspective on how acceptance and rejection impact change in ideal standards, ideal flexibility, and self-perceived mate value, but it does not explore the nuances of the context in which each experience of rejection or acceptance occurs, which would be useful and informative in increasing the understanding of the associations between these constructs.

The price levels of goods and services consumed by households are 25 to 28 percent higher in Sub-Saharan Africa than in other low- and middle-income countries, relative to their income levels
Is living in African cities expensive? Shohei Nakamura et al. Applied Economics Letters, https://doi.org/10.1080/13504851.2018.1527441
ABSTRACT: Although several studies have examined why overall price levels are higher in richer countries, little is known about whether there is a similar relationship at the urban and city level across countries. This paper compares the price levels of cities in Sub-Saharan Africa with those of other regions by analyzing price information collected for the purpose of calculating official purchasing power parities. The approach of the paper is to readjust the calculated price levels from national to urban levels, using known price-level ratios between those areas. The results indicate that African cities are relatively more expensive, despite having lower income levels. The price levels of goods and services consumed by households are 25 to 28 percent higher in Sub-Saharan Africa than in other low- and middle-income countries, relative to their income levels. Such high costs of living could constrain livelihood of low-income urban residents, as well as the development of Africa’s urban economies.

Robust evidence that public firms invest more overall, particularly in R&D, & dedicate more of their investment to R&D following IPO, & reduce upon going private

Washington: Board of Governors of the Federal Reserve System, https://doi.org/10.17016/FEDS.2018.068
Abstract: Using data from U.S. corporate tax returns, which provide a sample representative of the universe of U.S. corporations, we investigate the differential investment propensities of public and private firms. Re-weighting the data to generate observationally comparable sets of public and private firms, we find robust evidence that public firms invest more overall, particularly in R&D. Exploiting within-firm variation in public status, we find that firms dedicate more of their investment to R&D following IPO, and reduce these investments upon going private. Our findings suggest that public stock markets facilitate greater investment, on average, particularly in risky, uncollateralized investments.

Abstract: This study examined whether personality variables would account for political preferences during the 2016 U.S. Presidential Election using a demographically diverse sample of participants (N = 897). Study A revealed participants’ ratings of their own personality and emotions were weakly associated with political preferences, but their ratings of candidates’ personality showed robust associations, and were far more predictive of voting intention than all of the demographic variables, political affiliation, and racial attitudes combined. In Study B, linguistic analysis of narratives revealed words reflective of liberal values were correlated with positive evaluations of Clinton’s personality, whereas words reflective of conservative values and “populist” sentiment were correlated with positive evaluations of Trump’s personality, suggesting appraisals of candidates may be associated with values.

In steady heterosexual relationships men masturbate more than women because of gender differences in sex drive
In steady heterosexual relationships men masturbate more than women because of gender differences in sex drive. Wim Waterink. Submitted to New Voices in Psychology, http://www.gerontoseksuoloog.nl/Artikelen/Sex%20drive,%20masturbation%20and%20partnered%20sex.pdf
Abstract: In general, men and women differ with regard to the frequency of masturbation. Masturbation is more common among men than women. Masturbation is also more common among men than women in relationships. In a relationship this not always an appreciated fact. Relationship dissatisfaction can arise when a woman considers masturbation of her partner a substitute for partnered sex. This study investigated the suggestion that gender differences in the frequency of masturbation exists due to a gender difference in sex drive and that therefore masturbation of men engaged in a relationship is not a substitute for partnered sex. The research sample consisted of 554 Dutch participants of which were 355 women (mean age 42.02 years with a range of 20 to 72 years) and 199 men (mean age 44.62 years with a range of 22 to 76 years). All participants were engaged in a steady heterosexual relationship. In general it was found that a higher sex drive was associated with more masturbation and more partnered sex. More specific, women reported a masturbation frequency of about once per two weeks, that significantly differed from men. Men reported a masturbation frequency of about twice per week. Regarding reported frequency of partnered sex, no significant gender difference was found. Both, women and men, reported a frequency of about three times per two weeks. With regard to masturbation, a mediation analysis controlled for age with sex drive as a mediator, showed that sex drive significantly mediated, although not completely, the relationship between gender and the reported frequency of masturbation. The same mediation analysis was performed regarding the reported frequency of partnered sex. For partnered sex, sex drive also had significant mediation effect, but as a suppressor. It is concluded that in steady heterosexual relationships, the gender difference in sex drive is responsible for the fact that men masturbate more than wo men. Men masturbate more, because it is an easier outlet of sex drive than initiating partnered sex. Most important, for women in steady heterosexual relationships, as compared to men in steady heterosexual relationships, sex drive seems to be a less essential factor for partnered sex .

Current evolutionary adaptiveness of anxiety: Extreme phenotypes of anxiety predict increased fertility across multiple generations
Current evolutionary adaptiveness of anxiety: Extreme phenotypes of anxiety predict increased fertility across multiple generations. Nicholas C. Jacobson, Michael J. Roche. Journal of Psychiatric Research, https://doi.org/10.1016/j.jpsychires.2018.10.002
Abstract
Objective: Although recent research has begun to examine the impact of elevated anxiety on evolutionary fitness, no prior research has examined anxiety across a continuum. Such research is important as the effect of traits across a continuum on fertility hold important implications for the levels and distribution of the traits in later generations.
Method: In a three-generational sample (N = 2657) the linear and quadratic relationship between anxiety and the number of children, grandchildren, and great-grandchildren 15 years later was examined.
Results: The findings suggested that anxiety had a positive quadratic relationship with the number of children, grandchildren, and great-grandchildren 15 years later. These relationships were not significantly moderated by sex. Moreover, most of the variance between anxiety and the number of great-grandchildren was explained by anxiety's influence on the number of children and grandchildren, as opposed to anxiety having an independent direct impact on the number of great-grandchildren.
Conclusion: These findings suggest that extreme values from the mean anxiety are associated with increased evolutionary fitness within the modern environment.

Influence of small gifts on the outcome of business negotiations: small gifts matter, but tend to be counterproductive when purchasing and sales agents meet for the first time
Hidden Persuaders: Do Small Gifts Lubricate Business Negotiations? Michel André Maréchal, Christian Thöni. Management Science, https://doi.org/10.1287/mnsc.2018.3113
Abstract: Gift-giving customs are ubiquitous in social, political, and business life. Legal regulation and industry guidelines for gifts are often based on the assumption that large gifts potentially influence behavior and create conflicts of interest, but small gifts do not. However, scientific evidence on the impact of small gifts on business relationships is scarce. We conducted a natural field experiment in collaboration with sales agents of a multinational consumer products company to study the influence of small gifts on the outcome of business negotiations. We find that small gifts matter. On average, sales representatives generate more than twice as much revenue when they distribute a small gift at the onset of their negotiations. However, we also find that small gifts tend to be counterproductive when purchasing and sales agents meet for the first time, suggesting that the nature of the business relationship crucially affects the profitability of gifts.

Correlational but Not Causal Relationship Between Music Skill and Cognitive Ability
Sala, Giovanni, and Fernand Gobet. 2018. “Elvis Has Left the Building: Correlational but Not Causal Relationship Between Music Skill and Cognitive Ability.” PsyArXiv. September 8. doi:10.31234/osf.io/auzr
Abstract: Music training is commonly thought to have a positive impact on overall cognitive skills and academic achievement. This belief relies on the idea that engaging in an intellectually demanding activity helps to foster overall cognitive function. In this brief review, we show that, while music skill positively correlates with cognitive ability, music training does not enhance non-music cognitive skills or academic achievement. Interestingly, no significant effect on cognitive outcomes is observed even when music training leads to changes in the participants’ functional neural patterns. Crucially, the conclusion that music skills acquired by training do not generalize to non-music skills has been reached by several independent research groups via different methodologies. Such converging evidence suggests that the outcomes are highly reliable. The results have major implications. First, implementing music-training programs with the purpose of boosting individuals’ academic achievement or domain-general cognitive skills is not recommendable. Second, neural patterns induced by music training probably denote improvements in music-specific skills rather than overall cognitive function. Third, Thorndike and Woodworth’s (1901) common elements theory and theories based on chunking find further support. To date, far transfer remains a chimera.

Narcissism appears to be positively correlated with short-term mating (e.g., promiscuity), suggesting that narcissism gets pushed into subsequent generations via promiscuous activity, but narcissists are not physically attractive at the unadorned level
Did Narcissism Evolve? Nicholas S. Holtzman. Handbook of Trait Narcissism pp 173-181, https://link.springer.com/chapter/10.1007/978-3-319-92171-6_19
Abstract: This chapter, like each chapter in the edited book, focuses on narcissism (arrogance, exploitativeness, self-admiration, etc.). My goal is to entertain and evaluate the possibility that narcissism evolved. It is important to point out that, by way of background, just because something is morally suspect does not mean that it didn’t evolve; indeed, bad things can evolve. But despite narcissism being heritable, there is no direct evidence that narcissism is caused by specific genes, indicating that the evolutionary mechanisms are unknown. Through which pathways—such as mating pathways—does narcissism get passed onto the next generation? Narcissism appears to be positively correlated with short-term mating (e.g., promiscuity), suggesting that narcissism gets pushed into subsequent generations via promiscuous activity. The idea that narcissism evolved via short-term mating, however, is currently questionable, mainly because narcissists are not physically attractive at the unadorned level; in theory, narcissists should be attractive at the unadorned level because short-term mating situations select for raw attractiveness. All told, the prospect of narcissism having evolved is in a precarious position as of this writing. Several gaps in the literature lead to a call for more molecular genetic research and collaborative, large-scale behavioral research.

While risky sexual behavior & negative psychological correlates are associated with sexting & younger populations, the same might not be true for a nonuniversity-based, older adult sample
Sexting Leads to “Risky” Sex? An Analysis of Sexting Behaviors in a Nonuniversity-Based, Older Adult Population. Joseph M. Currin, Randolph D. Hubach, Carissa Sanders & Tonya R. Hammer. Journal of Sex & Marital Therapy, Volume 43, 2017 - Issue 7, Pages 689-702. https://doi.org/10.1080/0092623X.2016.1246390
Abstract: Since few researchers have analyzed sexting behaviors in nonuniversity-based adult samples, we sought to determine if sexting is associated with negative psychological correlates and risky sexual behaviors in this population. Analysis of individuals who indicated having vaginal or anal sex in the past 12 months and who identified as single (n = 377) showed that condomless sex is independent of sexting behaviors. Results for those in committed relationships (n = 374) and having had vaginal or anal sex in the past 12 months also demonstrated condomless sex and sexting behaviors were not related. Furthermore, alcohol consumption and relational health were predictive of sexting behaviors in adults in committed relationships. These findings demonstrate that while risky sexual behavior and negative psychological correlates are associated with sexting and younger populations, the same might not be true for a nonuniversity-based, older adult sample.

A reduction in the corporate income tax burden encourages adoption of the C corporation legal form; improved capital reallocation increases the overall productive efficiency in the economy and therefore reduce unemployment by up to 7pct
Corporate Income Tax, Legal Form of Organization, and Employment. Daphne Chen, Shi Qi, and Don Schlagenhauf. American Economic Journal: Macroeconomics. Oct 2018, Vol. 10, No. 4: Pages 270-304. https://pubs.aeaweb.org/doi/pdfplus/10.1257/mac.20140103
Abstract: A dynamic stochastic occupational choice model with heterogeneous agents is developed to evaluate the impact of a corporate income tax reduction on employment. In this framework, the key margin is the endogenous entrepreneurial choice of the legal form of organization. A reduction in the corporate income tax burden encourages adoption of the C corporation legal form, which reduces capital constraints on firms. Improved capital reallocation increases the overall productive efficiency in the economy and therefore expands the labor market. Relative to the benchmark economy, a corporate income tax cut can reduce the nonemployment rate by up to 7 percent. (JEL E24, H25, H32, J23, J24)

Sharing political rumors: Associated with "chaotic" motivations to "burn down" the entire established democratic "cosmos," not because those are viewed to be true but because they are believed to mobilize the audience against disliked elites
A "Need for Chaos" and the Sharing of Hostile Political Rumors in Advanced Democracies. Michael Bang Petersen, Mathias Osmundsen, Kevin Arceneaux. 114 th Annual Meeting of the American Political Science Association, Boston, MA, August 30 - September 2, 2018. https://osf.io/zsdce
Abstract: The circulation of hostile political rumors (including but not limited to false news and conspiracy theories) has gained prominence in public debates across advanced democracies. Here, we provide the first comprehensive assessment of the psychological syndrome that elicits motivations to share hostile political rumors among citizens of democratic societies. Against the notion that sharing occurs to help one mainstream political actor in the increasingly polarized electoral competition against other mainstream actors, we demonstrate that sharing motivations are associated with "chaotic" motivations to "burn down" the entire established democratic "cosmos". We show that this extreme discontent is associated with motivations to share hostile political rumors, not because such rumors are viewed to be true but because they are believed to mobilize the audience against disliked elites. We introduce an individual difference measure, the "Need for Chaos", to measure these motivations and illuminate their social causes, linked to frustrated status-seeking. Finally, we show that chaotic motivations are surprisingly widespread within advanced democracies, having some hold in up to 40 percent of the American national population.

German middle-aged homosexual men: 5.5% only had sexual experiences with women, and 10.3% recently had vaginal intercourse; of this, only 1/4 ever had sexual experience with a man, and 3/4 had only engaged in sexual activity with a woman
Goethe VE, Angerer H, Dinkel A, et al. Concordance and Discordance of Sexual Identity, Sexual Experience, and Current Sexual Behavior in 45-Year-Old-Men: Results From the German Male Sex-Study. Sex Med 201;X:XXX-XXX. https://doi.org/10.1016/j.esxm.2018.08.001
Abstract
Introduction: Discordance of various aspects of sexual orientation has been mostly studied in young adults or in small samples of heterosexual men. Studies focusing on concordance and discordance of aspects of sexual orientation in representative samples of middle-aged men including homosexual men are scarce.
Aim: To investigate concordant and discordant sexual behavior in 45-year-old German men with a special focus on homosexual identified men.
Methods: Data for this cross-sectional study were collected within the German Male Sex-Study. Participants were 45-year-old Caucasian males from the general population. Men self-reported on sexual identity, sexual experience, and current sexual behavior. Associations between sexual identity, experience, and behavior were analyzed using the chi-square test.
Main Outcome Measure: Associations of sexual identity with sexual experience and behavior in a community-based sample of men, and discordance of sexual identity and behavior especially in the subgroup of homosexual men.
Results: 12,354 men were included in the study. 95.1% (n = 11.749) self-identified as heterosexual, 3.8% (n = 471) as homosexual, and 1.1% (n = 134) as bisexual. Sexual identity was significantly associated with sexual experience and behavior. 85.5% of all men had recently been sexually active, but prevalence of sexual practices varied. In hetero- and bisexuals, vaginal intercourse was the most common sexual practice, whereas oral sex was the most common in homosexuals. A discordance of sexual identity was especially found in homosexual men: 5.5% of homosexuals only had sexual experiences with women, and 10.3% of homosexuals recently had vaginal intercourse. In this latter subgroup, only one-quarter ever had sexual experience with a man, and three-quarters had only engaged in sexual activity with a woman.
Conclusion: Sexual identity is associated with differences in sexual experience and behavior in German middle-aged men. A considerable proportion of homosexual identified men live a heterosexual life.

Having a political discussion with an out-group member led to more positive moral and affective evaluations of out-group members than having a discussion with an in-group member
Does Having a Political Discussion Help or Hurt Intergroup Perceptions? Drawing Guidance From Social Identity Theory and the Contact Hypothesis. Robert M. Bond, Hillary C. Shulman, Michael Gilbert. Bond Vol 12 (2018), http://ijoc.org/index.php/ijoc/article/view/9033
Abstract: This experiment (N = 238) tested propositions from social identity theory alongside the intergroup contact hypothesis to examine whether having a political discussion with an in-group (politically similar) or out-group (politically different) member affects subsequent evaluations of these social groups. Although several experimental results provide strong support for the antisocial predictions proposed by social identity theory, ultimately it was found that having a political discussion with an out-group member led to more positive moral and affective evaluations of out-group members than having a discussion with an in-group member. This result is consistent with the contact hypothesis and supports the notion that political discussions across party lines can produce positive social outcomes.

Selection for low male voice pitch is generally assumed to occur because it is a valid cue of formidability, but data suggest this is wrong
Sensory Exploitation, Sexual Dimorphism, and Human Voice Pitch. David R. Feinberg, Benedict C. Jones, Marie M. Armstrong. Trends in Ecology & Evolution, https://doi.org/10.1016/j.tree.2018.09.007
Abstract: Selection for low male voice pitch is generally assumed to occur because it is a valid cue of formidability. Here we summarize recent empirical challenges to this hypothesis. We also outline an alternative account in which selection for low male voice pitch is a byproduct of sensory exploitation.

Contrary to previous suggestions, deep male voices are no reliable indicators of "manly" attributes such as formidability, immunocompetence, or semen quality.

High physical attractiveness is related to low public self-consciousness, whereas low physical attractiveness is related to high public self-consciousness
Does beauty matter?: Exploring the relationship between self-consciousness and physical attractiveness. Wei-Lun Chang. Kybernetes, https://www.emeraldinsight.com/doi/abs/10.1108/K-12-2017-0494
Abstract
Purpose: The purpose of this study is to explore the relationship between self-consciousness and physical attractiveness from a psychological perspective, examining the relationship of physical attractiveness with the three dimensions of self-consciousness.
Design/methodology/approach: The research involved investigating the relationship between self-consciousness and physical attractiveness, focusing on how the three self-consciousness dimensions (i.e., private self-consciousness, public self-consciousness and social anxiety) affected physical attractiveness. Clustering techniques using self-organizing maps of data mining and decision trees were used in this study. The primal concept of clustering entails grouping unsorted and disorganized raw data and arranging data with similar properties into clusters. Classification primarily involves establishing classification models according to the category attributes of existing data. These models can be used to predict the classes of new data and determine interdata relationships and data characteristics.
Findings: Public self-consciousness was most strongly related to physical attractiveness, whereas the other two dimensions exhibited no obvious relationship to physical attractiveness. It may be concluded that people with higher physical attractiveness draw attention from others more easily and are more likely to be evaluated positively, and that they thus tend to be more confident in front of others and less likely to care about the opinions of others. Alternatively, perhaps people with lower public self-consciousness care less about how others view them and have the courage to express themselves, which signifies confidence and increases their physical attractiveness.
Practical implications: This research investigated the importance of self-consciousness that may apply to recruitment in practice. People with low public self-consciousness may have high confidence and efficiency. People have low social anxiety may not be nervous or anxious in public and easy to speak to strangers. This kind of employees are appropriate for the jobs involving team work and interaction such as public relations. Hence, companies can apply our findings to search appropriate employees except the first impression of appearance.
Originality/value: The results revealed that high physical attractiveness is related to low public self-consciousness, whereas low physical attractiveness is related to high public self-consciousness. Good-looking people tend to attract attention from others. The relationship between private self-consciousness and physical attractiveness is non-significant. The relationship between social anxiety and physical attractiveness is non-significant.

Why Suburban Districts Need Public Charter Schools Too. Emily Langhorne. Progressive Policy Institute, Oct 2 2018, https://www.progressivepolicy.org/publications/why-suburban-districts-need-public-charter-schools-too/
On November 8, 2016, while the rest of the world anxiously awaited the outcome of the U.S. presidential election, a subset of voters with a keen interest in education had their eyes on Massachusetts. This was the day Bay Staters would vote on Ballot Question 2, a proposal to raise the state’s cap on public charter schools by up to 12 new schools per year.
Massachusetts is home to some of the highest performing charter schools in the country, with especially impressive gains at schools serving urban, low-income and minority students. In Boston, one of the eight districts in the state to have reached its cap on charter schools, students at charters learn the equivalent of an extra year of math and reading each year, when compared to their peers with similar demographics and past test scores at the city’s traditional public schools.1The local school district, Boston Public Schools (BPS), enrolls about 53,000 students in a city of about 77,000 students. Currently, public charters enroll only about 10,000 students, but there are more than 32,000 children on waitlists for these schools.

Greedy individuals find a variety of transgressions more acceptable and justifiable as well as indicate that they have more often engaged in a variety of transgressions; were more likely to take a bribe and also preferred higher bribes
Greedy bastards: Testing the relationship between wanting more and unethical behavior. Terri G.Seuntjens, Marcel Zeelenberg, Nielsvan de Ven, Seger M.Breugelmans. Personality and Individual Differences, Volume 138, 1 February 2019, Pages 147-156. https://doi.org/10.1016/j.paid.2018.09.027
Abstract: Greed is often seen as immoral. Although the assumption that greed elicits unethical behavior is widespread, there is surprisingly little empirical research testing this relationship. We present a series of three studies investigating the association between greed and unethical behavior, using different methodologies and samples from the USA, The Netherlands, and Belgium. Study 1 (3 samples, total N = 3413) reveals that more greedy individuals find a variety of transgressions more acceptable and justifiable as well as indicate that they have more often engaged in a variety of transgressions compared to less greedy individuals. Study 2 (N = 172) replicated these findings in an incentivized behavioral laboratory study where participants decided to accept a bribe or not. Greedy people were more likely to take a bribe and also preferred higher bribes. Study 3 (N = 302) examined a potential process relating greed to unethical behavior. Greedy people were more likely to transgress because they found the positive outcomes associated with the transgression more desirable, and therefore displayed lower self-control. Implications for general theories of greed and morality are discussed.

Recycle more, waste more? When recycling efforts increase resource consumption
Recycle more, waste more? When recycling efforts increase resource consumption. Baolong Ma, Xiaofei Li, Zhongjun Jiang, Jiefan Jiang. Journal of Cleaner Production, https://doi.org/10.1016/j.jclepro.2018.09.063
Abstract: Governments spend significant amounts of money to promote recycling lifestyles to the public; however, they cannot maximize the beneficial effects of recycling without avoiding its potential negative consequences. In this research, we empirically examine the effects of recycling efforts on subsequent resource usage by analyzing the online survey data of 356 participants in China. Based on partial least squares-structural equation modeling, the results show that (1) recycling efforts have a positive effect on resource consumption, which suggests that engaging in recycling leads individuals to use significantly more resources in the future; (2) the positive effect of recycling efforts on resource consumption is mediated by environmental self-identity and feelings of pride; and (3) consideration of future consequences negatively moderates the effects of recycling efforts on environmental self-identity and on feelings of pride. That is, consideration of future consequences mitigates the positive effects of recycling efforts on resource consumption. The paper concludes with a discussion of the theoretical and managerial implications of our findings.

Genetic factors contribute substantially to the variations of various types of narcissism, stability of narcissism as well as its associations with other personalities, & the distinctions between different types of narcissism; environments (mostly non-shared by family members) also play important roles
The Etiology of Narcissism: A Review of Behavioral Genetic Studies. Yu L. L. Luo. Huajian Cai. In Handbook of Trait Narcissism pp 149-156, https://link.springer.com/chapter/10.1007/978-3-319-92171-6_16
Abstract: A great deal of research has delved into the etiology of narcissism via behavioral genetic methodologies in recent years. These studies have established that genetic factors contribute substantially to (1) the variations of various types of narcissism, (2) the stability of narcissism as well as its associations with other personalities, and (3) the distinctions between different types of narcissism. In the meantime, environments (mostly non-shared by family members) also play important roles in these situations. Together, these findings shed light on the origins of narcissism. Future studies may further examine how genetic and environmental factors interplay with each other in influencing narcissism and even what gene(s) is associated with narcissism.

Cognitive reflection was positively correlated with rational (selfish) behavior in dictator games; reflective dictators)kept more money for themselves than those who achieved lower scores on the CRT (altruistic, impulsive dictators)
Cognitive Reflection Test in Predicting Rational Behavior in the Dictator Game. Monika Czerwonka, Aleksandra Staniszewska, Krzysztof Kompa. In International Conference on Computational Methods in Experimental Economics CMEE 2017: Problems, Methods and Tools in Experimental and Behavioral Economics pp 301-312, https://link.springer.com/chapter/10.1007/978-3-319-99187-0_22
Abstract: Altruism and behavioral impact on economic decisions became the center of the interest for experimental and behavioral economy. The literature widely reports the results of variety types of dictator games (DG) and cognitive reflection tests (CRT). There is a broad research on donated sum, anonymity of the receiver and dictators’ position (giving vs. taking) in dictator games. Separately research on the CRT evolves from 3 questions to 7 questions variant. However, there is an evident gap in the literature for data that combines these two tools (DG and CRT) in one setup. In this study, we extend existing research on the relationship between cognitive performance on the CRT and dictator decisions taking into account such factors as donated sum, anonymity of the receiver and dictators’ position (giving vs. taking). The main goal is to find out if the cognitive reflection test (CRT) helps to predict rational (or selfish) behavior in a DG. In our investigation, we asked 511 participants to respond to 6 types of dictator games and CRT test. For statistical analysis of the received results, we applied correlation, descriptive statistics, the t-student test and the Mann–Whitney test. Our results show that cognitive reflection was positively correlated with rational (selfish) behavior in DGs. Those dictators who scored high on the CRT (reflective dictators) kept more money for themselves than those who achieved lower scores on the CRT (altruistic, impulsive dictators). Our results confirm an inequity aversion attitude among altruistic, impulsive dictators and selfish, reflective dictators.

Children Use Probability to Infer Other People’s Happiness; & they understand that our happiness with an outcome depends on whether a better or worse outcome was initially more likely
Children Use Probability to Infer Other People’s Happiness. Tiffany Doan, Ori Friedman, Stephanie Denison. CogSci 2018 Proceedings, https://mindmodeling.org/cogsci2018/papers/0314/0314.pdf
Abstract: The ability to infer other people’s emotions is an important aspect of children’s social cognition. Here, we examined whether 4- to 6-year-olds use probability to infer other people’s happiness. Children saw a scenario where a girl receives two desired and two undesired gumballs from a gumball machine and were asked to rate how the girl feel s about this outcome. Children either saw the gumballs come from a machine that had mostly desired gumballs or a machine that had mostly undesired gumballs. Five- and 6-year-olds rated the girl as being happier when the gumballs came from a machine that had mostly undesired gumballs. Four-year-olds, on the other hand, rated the girl’s happiness similarly regardless of whether the machine held mostly desired or undesired gumballs. These findings show that by the age of 5, children use probability to infer happiness. Further, they demonstrate that children understand that our happiness with an outcome depends on whether a better or worse outcome was initially more likely.

Followership evolved as a strategy to solve a range of cooperation and coordination problems in groups (e.g., collective movement, peacekeeping); individuals who lack the physical, psychological, or social capital to be leaders themselves are more likely to emerge as followers
The nature of followership: Evolutionary analysis and review. Nicolas astardoz, Mark Vugt. The Leadership Quarterly, https://doi.org/10.1016/j.leaqua.2018.09.004
Abstract: From an evolutionary perspective, followership is puzzling because it is not clear why individuals would relinquish their autonomy and set aside their personal goals to follow those of another individual, the leader. This paper analyzes followership from an evolutionary perspective and advances three main conclusions that are not yet part of the leadership literature. First, followership evolved as a strategy to solve a range of cooperation and coordination problems in groups (e.g., collective movement, peacekeeping). Second, individuals who lack the physical, psychological, or social capital to be leaders themselves are more likely to emerge as followers. Third, followership styles, behaviors, and engagement result from (a) variations in the relative pay-offs that accrue to followers vis-à-vis their leader, (b) the adaptive goals pursued by followers, (c) the adaptive challenges that select for different followership styles, and (d) the prevailing leadership style. Together, these conclusions have several implications for followership theory, research, and practice.

Those who believe in heaven and those who believe in hell tend to have negative attitudes toward physician-assisted suicide; the fear of hell, more so than the reward of heaven, may lead people to have negative attitudes toward physician-assisted suicide
Heaven, hell, and attitudes toward physician-assisted suicide. Shane Sharp. Journal of Health Psychology, https://doi.org/10.1177/1359105318800831
Abstract: Using data from the 2007 Baylor Religion Survey, I evaluate whether beliefs in heaven and hell are associated with attitudes toward physician-assisted suicide. I find that those who believe in heaven and those who believe in hell tend to have negative attitudes toward physician-assisted suicide, even when controlling for other religiosity and sociodemographic variables. I also find that the belief in hell mediates the effect of the belief in heaven on attitudes toward physician-assisted suicide, suggesting that the fear of hell, more so than the reward of heaven, may lead people to have negative attitudes toward physician-assisted suicide.

The dark triad of personality `predicts how eudaimonic narratives (stories dealing with purpose in life, the human condition, and human virtue) are perceived: inauthentic & corny
Repelled by Virtue? The Dark Triad and Eudaimonic Narratives. Markus Appel, Michael D Slater, Mary Beth Oliver. Media Psychology, accepted September 2018. DOI: 10.1080/15213269.2018.1523014
Abstract: We propose that the dark triad of personality predicts how recipients respond to eudaimonic narratives (stories dealing with purpose in life, the human condition, and human virtue). Matched eudaimonic or non-eudaimonic videos were presented via random assignment. The more individuals lack empathy and organize their world around self-promotion – reflected in the so-called dark triad of narcissism, Machiavellianism, and psychopathy – the more they perceived the eudaimonic stories (vs. control) to be inauthentic and corny (perceived corniness). This effect translated to a more negative overall evaluation of the eudaimonic videos (moderated mediation). Self-reported feelings of being touched, moved, and inspired (meaningful affect) were largely unaffected by the dark triad, suggesting that these personality factors do not disable emotional responses to eudaimonic narratives.

Over 4 years, substantial numbers of Americans change how they identify along the lines of national origin, sexual orientation, religion, & class
Identity as Dependent Variable: How Americans Shift Their Identities to Better Align With Their Politics. Patrick J. Egan, Wilf Family Department of Politics, New York University, September 10, 2018, https://rubenson.org/wp-content/uploads/2018/09/egan-tpbw18.pdf
Political science generally treats demographic identities as “unmoved movers” in the chain of causality because these identities are conceptualized as being rooted in either ascriptive individual characteristics or hard-to-change aspects of individual experience. Here I hypothesize that the increasingly salient nature of partisanship and ideology as social identities leads liberal Democrats and conservative Republicans to shift their demo- graphic identities to better align with the prototypes of their political groups, and thus the identity groups that make up the left and right coalitions in U.S. politics. I explore the hypothesis with a panel dataset that tracks Americans’ identities and political affiliations over four years. The data show that substantial numbers of Americans change how they identify over this span along the lines of national origin, sexual orientation, religion, and class. Furthermore, identity switching with regard to Latino origin, religion, class, and sexual orientation is significantly predicted by Americans’ partisanship and ideology in their pasts. All of these shifts are in directions that bring Americans’ identities into better alignment with their politics. Politics plays a particularly important role in identification with two identity groups—lesbians, gays and bisexuals, and those identifying as having no religious affiliation—in that the impact of politics on identity is large for these groups relative to their prevalence in the population. In showing how the process of identification can be imbued with politics, these findings both enrich and complicate our efforts to un- derstand the relationship between identity and political behavior and indicate that caution must be taken in treating identities as firm, immovable political phenomena.

Acting on their fantasies was as good or better than expected & it improved relationships, especially those already in good relationships, people with a higher sex drive & thrill-seeking tendencies, & people who adapt to stress & uncertainty
Seven Fascinating Facts About Sexual Fantasies. Justin J Lehmiller. Psychology Today, Oct 01, 2018. https://www.psychologytoday.com/intl/blog/the-myths-sex/201810/seven-fascinating-facts-about-sexual-fantasies
3.) While threesomes were the most popular fantasy, they were also the fantasy that was least likely to turn out well when people acted on it. This is probably due, in part, to the fact that different people prefer different threesome scenarios, which may make it challenging for everyone to get what they want. However, it’s probably also due to the fact that most people don’t have a script for how a threesome should go, which means that many people end up in a multi-partner situation with a lot of uncertainty about who should be doing what with whom and when.
7.) For the most part, people who acted on their favorite sex fantasies reported that things turned out well. The numbers varied a bit depending on what it is that they did—and, as mentioned above, group sex was the least likely fantasy to turn out well. Overall, though, most people said that acting on their fantasies was at least as good or better than expected and that it improved their relationship. However, some people were more likely to have positive experiences than others, and that included people who were already in good relationships to start with, people with a higher sex drive and thrill-seeking tendencies, and people who are good at adapting to stress and uncertainty, meaning people who are low in the personality trait of neuroticism.
