Marriage, Fertility, and Cultural Integration in Italy. Alberto Bisin, Giulia Tura. NBER Working Paper No. 26303, September 2019. https://www.nber.org/papers/w26303
We study the cultural integration of immigrants, estimating a structural model of marital matching along ethnic dimensions, exploring in detail the role of fertility, and possibly divorce in the integration process. We exploit rich administrative demographic data on the universe of marriages formed in Italy, as well as birth and separation records from 1995 to 2012. We estimate strong preferences of ethnic minorities' towards socialization of children to their own identity, identifying marital selection and fertility choices as fundamental socialization mechanisms. The estimated cultural intolerance of Italians towards immigrant minorities is also substantial. Turning to long-run simulations, we find that cultural intolerances, as well as fertility and homogamy rates, slow-down the cultural integration of some immigrant ethnic minorities, especially Latin America, East Asia and Sub-Saharan Africa. Nonetheless, 75% of immigrants integrate into the majoritarian culture over the period of a generation. Interestingly, we show by counterfactual analysis that a lower cultural intolerance of Italians towards minorities would lead to slower cultural integration by allowing immigrants a more widespread use of their own language rather than Italian in heterogamous marriages. Finally, we quantitatively assess the effects of large future immigration inflows.

Women & men perception of breasts: The bigger, the higher the reproductive efficiency, lactational efficiency, sexual desire, promiscuity attributed; & perceived as less faithful & less intelligent
Stereotypical and Actual Associations of Breast Size with Mating-Relevant Traits. Krzysztof Kościński, Rafał Makarewicz, Zbigniew Bartoszewicz. Archives of Sexual Behavior, September 27 2019. https://link.springer.com/article/10.1007/s10508-019-1464-z
Abstract: Breast size varies substantially among women and influences perception of the woman by other people with regard to her attractiveness and other characteristics that are important in social contexts, including mating. The theory of sexual selection predicts that physical criteria of partner selection should be markers of the candidate’s desirable properties, mainly biological quality. Few studies, however, have examined whether breast size really signals biological quality or its components and whether observers accurately interpret these signals. Our first study encompassed 163 young women and aimed to establish actual correlates of breast size. The aim of the second study was to determine preferences and stereotypes related to breast size: 252–265 women and men evaluated female digital figures varying in, among other characteristics, breast size. Breast size (breast circumference minus chest circumference) was negatively associated with body asymmetry and positively associated with infections of the respiratory system, but did not correlate with infections of the digestive system, openness to casual sex, and testosterone and estradiol level. Women and men perceived breasts in a similar way to each other: the bigger the breasts the higher the reproductive efficiency, lactational efficiency, sexual desire, and promiscuity attributed to the woman. Nevertheless, large breasts were not regarded more attractive than average ones, though small breasts were the least attractive. In addition, big-breasted women were perceived as less faithful and less intelligent than women with average or small breasts. We discuss our results from the perspectives of evolutionary psychology, perceptual biases, and social stereotypes.

A mindset of optimism is associated with lower cardiovascular risk and that promotion of optimism and reduction in pessimism may be important for preventive health
Association of Optimism With Cardiovascular Events and All-Cause Mortality - A Systematic Review and Meta-analysis. Alan Rozanski et al. JAMA Netw Open. 2019;2(9):e1912200. September 27, 2019. doi:10.1001/jamanetworkopen.2019.12200
Key Points
Question Is a mindset of optimism associated with a lower risk of cardiovascular events and all-cause mortality?
Findings In this meta-analysis of 15 studies including 229 391 individuals, optimism was associated with a lower risk of cardiovascular events and pessimism was associated with a higher risk of cardiovascular events; the pooled association was similar to that of other well-established cardiac risk factors.
Meaning The findings suggest that a mindset of optimism is associated with lower cardiovascular risk and that promotion of optimism and reduction in pessimism may be important for preventive health.
Abstract
Importance Optimism and pessimism can be easily measured and are potentially modifiable mindsets that may be associated with cardiovascular risk and all-cause mortality.
Objective To conduct a meta-analysis and systematic review of the association between optimism and risk for future cardiovascular events and all-cause mortality.
Data Sources and Study Selection PubMed, Scopus, and PsycINFO electronic databases were systematically searched from inception through July 2, 2019, to identify all cohort studies investigating the association between optimism and pessimism and cardiovascular events and/or all-cause mortality by using the following Medical Subject Heading terms: optimism, optimistic explanatory style, pessimism, outcomes, endpoint, mortality, death, cardiovascular events, stroke, coronary artery disease, coronary heart disease, ischemic heart disease, and cardiovascular disease.
Data Extraction and Synthesis Data were screened and extracted independently by 2 investigators (A.R. and C.B.). Adjusted effect estimates were used, and pooled analysis was performed using the Hartung-Knapp-Sidik-Jonkman random-effects model. Sensitivity and subgroup analyses were performed to assess the robustness of the findings. The Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guideline was followed.
Main Outcomes and Measures Cardiovascular events included a composite of fatal cardiovascular mortality, nonfatal myocardial infarction, stroke, and/or new-onset angina. All-cause mortality was assessed as a separate outcome.
Results The search yielded 15 studies comprising 229 391 participants of which 10 studies reported data on cardiovascular events and 9 studies reported data on all-cause mortality. The mean follow-up period was 13.8 years (range, 2-40 years). On pooled analysis, optimism was significantly associated with a decreased risk of cardiovascular events (relative risk, 0.65; 95% CI, 0.51-0.78; P < .001), with high heterogeneity in the analysis (I2 = 87.4%). Similarly, optimism was significantly associated with a lower risk of all-cause mortality (relative risk, 0.86; 95% CI, 0.80-0.92; P < .001), with moderate heterogeneity (I2 = 73.2%). Subgroup analyses by methods for assessment, follow-up duration, sex, and adjustment for depression and other potential confounders yielded similar results.
Conclusions and Relevance The findings suggest that optimism is associated with a lower risk of cardiovascular events and all-cause mortality. Future studies should seek to better define the biobehavioral mechanisms underlying this association and evaluate the potential benefit of interventions designed to promote optimism or reduce pessimism.
Introduction
Extensive evidence has demonstrated an association between negative emotions, social factors, and certain chronic stress conditions and adverse cardiac outcomes.1 Less well studied has been the potential association between positive and negative mindsets and cardiac risk. Such research is of interest because mind-sets are potentially modifiable, thus making them a novel relevant target for clinical intervention. One such mindset is an individual’s level of optimism, commonly defined as the tendency to think that good things will happen in the future.2 Empirical studies have long indicated that more optimistic individuals are more likely to succeed at work and in school, sports, politics, relationships, and other forms of life endeavors.3,4 A more recent study also reported positive associations between optimism and a range of favorable physical health outcomes.5 Nevertheless, the assessment of optimism and pessimism in cardiac medical practice is uncommon. In 2001, Kubzansky and colleagues6 reported the first study, to our knowledge, to find an association between higher optimism and a lower risk for specific cardiac outcomes, including angina, myocardial infarction, and cardiac death. They showed effects of optimism beyond those of depression or other forms of psychological distress, a critical finding because a concern about such findings is that they simply reflect the absence of depression rather than active effects of optimism. Since then, similar findings have been described in other studies,7-20 and most studies considered depression or distress as a potential confounder. To consider these findings more systematically, we conducted a meta-analysis of studies that have assessed the association between optimism and pessimism and adverse cardiac outcomes. Our goals were to evaluate the magnitude of this association, the consistency of results among reported studies, the influence of potential confounders, and the quality of the reported literature.

Vegetarian diets may be perceived as inadequately nutritious, inadequately tasty, socially stigmatizing, too expensive, unfamiliar, inconvenient; dominant factors are the two first
Taste and health concerns trump anticipated stigma as barriers to vegetarianism. Daniel L.Rosenfeld, A. JanetTomiyama. Appetite, Volume 144, January 1 2020, 104469. https://doi.org/10.1016/j.appet.2019.104469
Abstract: Meat-eaters report that a number of barriers inhibit them from going vegetarian—for example, perceiving vegetarian diets to be inadequately nutritious, too expensive, unfamiliar, inconvenient, inadequately tasty, and socially stigmatizing. However, research identifying which barriers uniquely predict meat-eaters’ openness to going vegetarian is lacking from the current literature. In the present research, accordingly, we conducted a highly powered, preregistered study (N = 579) to identify which barriers uniquely predict openness to going vegetarian. We focused specifically on anticipated vegetarian stigma, given recent qualitative evidence highlighting this attitude as an influential barrier. That is, do meat-eaters resist going vegetarian because they fear that following a vegetarian diet would make them feel stigmatized? Being of younger age, more politically conservative, White, and residing in a rural community predicted greater anticipated vegetarian stigma among meat-eaters. Frequentist and Bayesian analyses converged, however, to suggest that anticipated vegetarian stigma was not a significant predictor of openness to going vegetarian. The strongest predictors of openness were perceived tastiness and perceived healthfulness of vegetarian dieting. These factors—but not anticipated stigma—furthermore explained why men (compared to women) and political conservatives (compared to liberals) were particularly resistant to going vegetarian.

Bullshitting frequency was positively associated with overclaiming and negatively associated with sincere self-presentation, honesty, cognitive ability, open-minded cognition, & self-regard
Littrell, Shane, Evan Risko, and Jonathan A. Fugelsang. 2019. “The Bullshitting Frequency Scale: Development and Psychometric Properties.” PsyArXiv. September 27. doi:10.31234/osf.io/dxzqh
Abstract: Recent psychological research has identified important individual differences associated with receptivity to bullshit which has greatly enhanced our understanding of the processes behind susceptibility to pseudo-profound or otherwise misleading information. However, the bulk of this research attention has focused on cognitive and dispositional factors related to bullshit (the product), while largely overlooking the influences behind bullshitting (the act), leaving several important theoretical questions thus far unanswered. Here, we present results from three studies focusing on the construction and validation of a new, reliable scale measuring the frequency with which individuals engage in bullshitting in everyday situations. Overall, bullshitting frequency was positively associated with overclaiming and negatively associated with sincere self-presentation, honesty, cognitive ability, open-minded cognition, and self-regard. These results represent an important step forward by demonstrating the utility of the Bullshitting Frequency Scale as well as highlighting certain individual differences that may play important roles in the extent to which individuals engage in everyday bullshitting.
Introduction
“One of the most salient features of our culture is that there is so much bullshit. Everyone knows this. Each of us contributes his share.” – Harry Frankfurt (1986)
Given the increasing prevalence of misleading information and “fake news” on the internet and society at large (Lewandosky, Ecker, & Cook, 2017), a growing body of work has emerged that focuses on better understanding the nature of bullshit and bullshitting. Some has been more descriptive, highlighting the use of bullshit in politics (Kristansen & Kaussler, 2018), business organizations (Martin & Wilson, 2011; Spicer, 2013), academic settings (Cohen, 2012), and everyday life (Frankfurt, 1986). Other research, in psychology, has taken a more empirical approach, examining individual differences associated with receptivity to bullshit and the production of bullshit (i.e., bullshitting). For instance, multiple studies have linked bullshit receptivity (i.e., the propensity to rate vacuous, randomly-generated statements as profound) to factors such as decreased engagement in analytic thinking (Pennycook, Cheyene, Barr, Koehler, & Fugelsang, 2015) and biased pattern perception (Walker, Turpin, Stolz, Fugelsang, & Koehler, 2019). Other work has examined the functions of bullshit production (i.e., bullshitting) as a strategy for managing impressions and attitude change in areas from simple social interactions to assessments of abstract art (Petrocelli, 2018; Turpin et al., 2019).
Bullshitting, broadly defined
Philosopher Harry Frankfurt (1986) is perhaps best known for his seminal piece, On Bullshit, in which he described a “bullshitter” as a person who deliberately conveys a false/phony impression of himself or his intentions in a way that is unconcerned with the truth. In other words, the veracity of what the bullshitter is saying does not matter, as his or her primary concern is whether others are persuaded by it. Frankfurt contrasts this from lying in that the liar is deliberately attempting to get others to believe a falsehood. A key distinction is in the motivation; a liar’s goal is to deceive whereas a bullshitter’s goal is often to impress.
Though this explication of bullshitting is generally well-regarded, some have critiqued it as capturing “just one flower in the lush garden of bullshit” (Cohen, 2012). Indeed, several have modified or expanded on his definitions to provide a more comprehensive view of bullshitting in daily life. For instance, Cohen (2012) highlighted that the aim of some bullshitters is to impress using discourse constructed with “unclarifiable unclarity”; that is, relying on vacuous, confusing buzzwords which obscure the fact that the statements, while superficially impressive, contain no discernible meaning. An example cited is the arguably impenetrable, jargon-heavy writing found in some academic publications. For Cohen, this type of bullshit is distinct from Frankfurtian bullshit in that the Cohen-bullshitter is unconcerned with the lucidity of what he says, rather than unconcerned with its truth-value (Cohen, 2012).
Another proposed type of bullshit/bullshitting is evasive bullshitting, which involves speech aimed at avoiding answering questions one does not want to answer, as giving direct answers may be harmful to oneself or others (Carson, 2016). For instance, a politician may be motivated to use evasive bullshitting when questioned by a member of the press if, for instance, a direct answer could potentially cost votes (harm to self) or jeopardize national security (harm to others). An equally common example might be one’s romantic partner asking if their new haircut or outfit makes them look unattractive. In some cases, a frank response might result in undesirable social costs for either party (or both).
Finally, some have attempted to refine Frankfurt’s assertion that bullshitting, by definition, is unconnected to a concern for the truth (Frankfurt, 1986, p. 90). For instance, Stokke and Fallis (2017) characterize bullshitting as speech that is unconcerned with the truthful advancement of an honest discourse, rather than unconcerned with the veracity of individual statements. Put another way, the bullshitter is not indifferent toward the truth-value of the content of each thing he says. Rather, he is indifferent toward whether his statements create an impression that the overall discourse leads to an honest representation of the truth. Meibauer (2018) describes bullshitting as having a “misrepresentational intent” that is based on “a loose concern for the truth” (p. 366). That is, the bullshitter may not know the truth-value of his statements, yet he is often aware of his unawareness, and asserts himself with a sense of certainty that his statements are true regardless. Indeed, the bullshitter’s goal is not to communicate an objective truth, but to instill a particular belief or impression in another person – regardless of whether the bullshitter also believes it – and can be accomplished through misleading exaggeration or implicature (Stokke & Fallis, 2017; Webber, 2013).

Claims for mirror self-recognition have been made for numerous species ranging from dolphins and elephants to fish and ants; reproducible experimental evidence is avaialable only for some great apes

Abstract: Claims for mirror self-recognition have been made for numerous species ranging from dolphins and elephants to fish and ants. But based on rigorous, reproducible experimental evidence only some great apes and humans have shown clear, consistent and convincing evidence that they are capable of correctly deciphering mirrored information about themselves. In this article we critique some of the recent claims for self-recognition in other species and summarize some of the cognitive implications of the capacity to become the object of your own attention. Recent neurobiological evidence now appears to validate the connection between self-recognition and self-awareness.

From 2015... Male homosexual preference: Available data challenges the common view of MHP being a “virtually universal” trait; social stratification together with hypergyny seem necessary for its evolution
From 2015... Barthes J, Crochet P-A, Raymond M (2015) Male Homosexual Preference: Where, When, Why? PLoS ONE 10(8), Aug 12 2016, e0134817. https://doi.org/10.1371/journal.pone.0134817
Abstract: Male homosexual preference (MHP) has long been of interest to scholars studying the evolution of human sexuality. Indeed, MHP is partially heritable, induces a reproductive cost and is common. MHP has thus been considered a Darwinian paradox. Several questions arise when MHP is considered in an evolutionary context. At what point did MHP appear in the human evolutionary history? Is MHP present in all human groups? How has MHP evolved, given that MHP is a reproductively costly trait? These questions were addressed here, using data from the anthropological and archaeological literature. Our detailed analysis of the available data challenges the common view of MHP being a “virtually universal” trait present in humans since prehistory. The conditions under which it is possible to affirm that MHP was present in past societies are discussed. Furthermore, using anthropological reports, the presence or absence of MHP was documented for 107 societies, allowing us to conclude that evidence of the absence of MHP is available for some societies. A recent evolutionary hypothesis has argued that social stratification together with hypergyny (the hypergyny hypothesis) are necessary conditions for the evolution of MHP. Here, the link between the level of stratification and the probability of observing MHP was tested using an unprecedented large dataset. Furthermore, the test was performed for the first time by controlling for the phylogenetic non-independence between societies. A positive relationship was observed between the level of social stratification and the probability of observing MHP, supporting the hypergyny hypothesis.
From 2016... Homophobia might reflect concerns about sexuality in general and not homosexuality in particular
From 2016... Homophobia Is Related to a Low Interest in Sexuality in General: An Analysis of Pupillometric Evoked Responses. Boris Cheval et al. The Journal of Sexual Medicine, Volume 13, Issue 10, October 2016, Pages 1539-1545. https://doi.org/10.1016/j.jsxm.2016.07.013
Abstract
Introduction: A recent study by Cheval et al (J Sex Med 2016;13:825–834) found that individuals high in homophobia look significantly less long at sex-related photographs, regardless of their nature (ie, homosexual or heterosexual). Because viewing time is under some conscious control, this result could indicate that individuals high in homophobia have a low sexual interest in any sexual stimuli or are consciously motivated to avoid sexual material in line with their conscious values.
Aim: To determine the mechanism underlying shorter viewing time of sex-related photographs in individuals high in homophobia using pupil dilatation, which is considered a spontaneous, unconscious, and uncontrollable index of sexual interest.
Methods: Heterosexual men (N = 36) completed a questionnaire assessing their level of homo-negativity and then performed a picture-viewing task with simultaneous eye-tracking recording to assess their pupillary responses to the presentation of sexually related or neutral photographs.
Main Outcome Measures: Non-linear mixed models were carried out to fit the individual non-linear trajectories of pupillary reaction. Different parameters were obtained including the final asymptote of the pupillary response.
Results: Results showed that the final pupil size of men high in homophobia increased significantly less to the presentation of sex-related images (ie, heterosexual and homosexual) than the pupil size of men low in homophobia. In contrast, no significant difference in the final pupil size reaction toward homosexual images (vs heterosexual images) emerged between men high and men low in homophobia.
Conclusion: Theoretically, these findings reinforce the necessity to consider that homophobia might reflect concerns about sexuality in general and not homosexuality in particular.

Moderate to strong evidence for the absence of an experimental effect: Belief in a controlling God did not increase after a threat compared to an affirmation of personal control (US & the Netherlands)
Hoogeveen, Suzanne, Eric-Jan Wagenmakers, Aaron Kay, and Michiel van Elk. 2019. “Compensatory Control and Belief in God: A Registered Replication Report Across Two Countries.” PsyArXiv. September 27. doi:10.31234/osf.io/vqu2x
Abstract: Compensatory Control Theory (CCT) suggests that religious belief systems provide an external source of control that can substitute a perceived lack of personal control. In a seminal paper, Kay et al. (2008) experimentally demonstrated that a threat to personal control increases endorsement of the existence of a controlling God. In the current registered report, we conducted a high-powered (N = 829) direct replication of this effect, using samples from the Netherlands and the United States. Our results show moderate to strong evidence for the absence of an experimental effect across both countries: belief in a controlling God did not increase after a threat compared to an affirmation of personal control. In a complementary preregistered analysis, an inverse relation between general feelings of personal control and belief in a controlling God was found in the US, but not in the Netherlands. We discuss potential reasons for the replication failure of the experimental effect and cultural mechanisms explaining the cross-country difference in the correlational effect. Together, our findings suggest that experimental manipulations of control may be ineffective in shifting belief in God, but that individual differences in the experience of control may be related to religious beliefs in a way that is consistent with CCT.

Religiosity Predicts Evidentiary Standards: Religious individuals exhibited a bias for believing religious claims relative to scientific claims, while nonreligious guys were consistent in their standards of evidence across domains
Religiosity Predicts Evidentiary Standards. Emilio J. C. Lobato et al. Social Psychological and Personality Science, September 9, 2019. https://doi.org/10.1177/1948550619869613
Abstract: Research shows that religious and nonreligious individuals have different standards of evidence for religious and scientific claims. Here, in a preregistered replication and extension of McPhetres and Zuckerman, participants read about an effect attributed to either a scientific or religious cause, then assessed how much evidence, in the form of successful replications, would be needed to confirm or to reject the causal claim. As previously observed, religious individuals exhibited a bias for believing religious claims relative to scientific claims, while nonreligious individuals were consistent in their standards of evidence across domains. In a novel extension examining standards of evidence with respect to failures of replication, we found that religious individuals were consistent across domains, whereas nonreligious individuals indicated a lower threshold for rejecting religious claims relative to scientific claims. These findings indicate asymmetries in the evaluation of claims based on the presence versus absence of supportive evidence.

Facebook is found as a useful tool to fulfil human needs, which predict continued Facebook use intentions of participants, and further, satisfaction with life
Who Needs Social Networking? An Empirical Enquiry into the Capability of Facebook to Meet Human Needs and Satisfaction with Life. David Houghton, Andrew Pressey, Doga Istanbulluoglu. Computers in Human Behavior, September 27 2019. https://doi.org/10.1016/j.chb.2019.09.029
Highlights:
• Investigation into the fulfilment of human needs through Facebook use.
• SEM to assess human needs, Facebook use and Satisfaction with Life.
• Facebook fulfils needs, and continued use is associated with satisfaction with life.
Abstract: Social Network Sites (SNS) have been the topic of much scholarly and public debate for the most part of the 21st century. A number of studies have investigated the benefits and drawbacks to using SNS, with Facebook the largest example boasting billions of active monthly users. In recent months, media commentary has raised a number of concerning cases surrounding Facebook’s use of data, its connection with other organizations and its legitimacy, making a number of open public calls to abandon the platform. However, active users still number in the billions, raising the question, “does Facebook achieve something on a fundamental human and social level that users are willing to overlook the potential drawback to its use?” Using Maslow’s needs hierarchy, this study adopts a survey approach (n=316) and explores the capacity for Facebook to satisfy human needs. Findings identify Facebook as a useful tool to fulfil human needs, which predict continued Facebook use intentions of participants, and further, satisfaction with life. These findings offer a broad-based view of Facebook use and its resonance with key motivators of behavior, supporting both Maslow’s needs hierarchy and highlighting the importance of need fulfilment for continued service use and satisfaction with life.

Those who are off Facebook for one week reduce news consumption, are less likely to recognize politically-skewed news stories, report being less depressed and engage in healthier activities. These results are strongest for men. Our results further suggest that, after the restriction, Facebook’s value increases, consistent with information loss or that using Facebook may be addictive.
The Social Effects of Internet Deprivation: Can You Engage in Political Activity Without Internet Access? Very little, it seems
Can You Engage in Political Activity Without Internet Access? The Social Effects of Internet Deprivation. Ryan Shandler, Michael L Gross, Daphna Canetti. Political Studies Review, September 26, 2019. https://doi.org/10.1177/1478929919877600
Abstract: To what extent can you engage in political activity in the modern age without Internet access? The growing dependence on Internet access to fulfill basic civil functions is threatened by increasing personal and societal cyber vulnerability. In this article, we explore the extent to which citizens are able, or unable, to engage in specific political activities in the absence of Internet connectivity. To concretize the subject, we test how Internet deprivation affects the ability to realize three basic elements of political participation: political expression, civic association, and access to information. To measure this, we develop a new experimental methodology that tests people’s ability to complete tasks related to each function under simulated treatments of Internet access or deprivation. This empirical methodology offers a new framework through which to quantify the realization of social tasks under experimental conditions. Early results suggest that the absence of Internet access significantly reduces task completion for activities related to political expression and political association and conditionally reduces task completion for practices associated with freedom of information. Having substantiated this empirical framework, we encourage its application to additional forms of political activity.

When a woman is more attractive than her mate, men desire to mate poach, and if a woman is less attractive than her partner, men desire to mate copy
Moran, J. B., & Wade, T. J. (2019). Perceptions of a mismatched couple: The role of attractiveness on mate poaching and copying. Evolutionary Behavioral Sciences, Sep 2019. http://dx.doi.org/10.1037/ebs0000187
Abstract: This research investigated how a couple’s discrepancy in attractiveness influences men’s decision to mate poach or mate copy. The participants (N = 97 heterosexual men) were presented with 3 photos of a quasi couple in which the woman was consistent, and the 3 men were unattractive, equally, or more attractive than her. This study used ranking questions to assess heterosexual men’s perception of a couple. Participants were asked to drag and drop the 3 randomized photos in order of preference for 8 randomized questions regarding mate poaching and mate copying. Eight Friedman tests were conducted and revealed a significant difference between the rankings of the photos for each situation. These findings suggest that there are clear differences between the conditional mating strategies men use. Results revealed that when a woman is more attractive than her mate, men desire to mate poach, and if a woman is less attractive than her partner, men desire to mate copy.

The relationship between tickling, sensation, and laughter is complex; tickling or its mere anticipation makes us laugh, but not when we self-tickle; the study uses rats to understand self-tickle suppression & tickle anticipation
Behavioral and Cortical Correlates of Self-Suppression, Anticipation, and Ambivalence in Rat Tickling. Shimpei Ishiyama, Lena V. Kaufmann, Michael Brecht. Current Biology, September 26 2019. https://doi.org/10.1016/j.cub.2019.07.085
Highlights
• Self-touch suppresses vocalizations and cortical excitation
• Self-touch suppression is rescued by blocking cortical inhibition
• Rats show ambivalent response to tickling
• Layer 5 somatosensory cortex represents tickle anticipation
Summary: The relationship between tickling, sensation, and laughter is complex. Tickling or its mere anticipation makes us laugh, but not when we self-tickle. We previously showed rat somatosensory cortex drives tickling-evoked vocalizations and now investigated self-tickle suppression and tickle anticipation. We recorded somatosensory cortex activity while tickling and touching rats and while rats touched themselves. Allo-touch and tickling evoked somatotopic cortical excitation and vocalizations. Self-touch induced wide-ranging inhibition and vocalization suppression. Self-touch also suppressed vocalizations and cortical responses evoked by allo-touch or cortical microstimulation. We suggest a global-inhibition model of self-tickle suppression, which operates without the classically assumed self versus other distinction. Consistent with this inhibition hypothesis, blocking cortical inhibition with gabazine abolished self-tickle suppression. We studied anticipation in a nose-poke-for-tickling paradigm. Although rats nose poked for tickling, they also showed escaping, freezing, and alarm calls. Such ambivalence (“Nervenkitzel”) resembles tickle behaviors in children. We conclude that self-touch-induced GABAergic cortical inhibition prevents self-tickle, whereas anticipatory layer 5 activity drives anticipatory laughter.

The economic effects of Facebook. Roberto Mosquera et al. Experimental Economics, September 26 2019. https://link.springer.com/article/10.1007/s10683-019-09625-y
Abstract: Social media permeates many aspects of our lives, including how we connect with others, where we get our news and how we spend our time. Yet, we know little about the economic effects for users. In 2017, we ran a large field experiment with over 1765 individuals to document the value of Facebook to users and its causal effect on news, well-being and daily activities. Participants reveal how much they value one week of Facebook usage and are then randomly assigned to a validated Facebook restriction or normal use. One week of Facebook is worth $67. Those who are off Facebook for one week reduce news consumption, are less likely to recognize politically-skewed news stories, report being less depressed and engage in healthier activities. These results are strongest for men. Our results further suggest that, after the restriction, Facebook’s value increases, consistent with information loss or that using Facebook may be addictive.

The link between people’s social relationships and their level of self-esteem is truly reciprocal in all developmental stages across the life span, reflecting a positive feedback loop between the constructs
Harris, M. A., & Orth, U. (2019, September 26). The Link Between Self-Esteem and Social Relationships: A Meta-Analysis of Longitudinal Studies. Journal of Personality and Social Psychology, Sep 26 2019. http://dx.doi.org/10.1037/pspp0000265
Theorists have long assumed that people’s self-esteem and social relationships influence each other. However, the empirical evidence has been inconsistent, creating substantial uncertainty about whetherrelationships are in fact an influential factor in self-esteem development and vice versa. This meta-analysis synthesizes the available longitudinal data on the prospective effect of social relationships on self-esteem (48 samples including 46,231 participants) and the prospective effect of self-esteem on social relationships (35 samples including 21,995 participants). All effects controlled for prior levels of the outcomes. Results showed that relationships and self-esteem reciprocally predict each other over time with similar effect sizes (beta=.08 in both directions). Moderator analyses suggested that the effects heldcacross sample characteristics such as mean age, gender, ethnicity, and time lag between assessments, except for the self-esteem effect on relationships, which was moderated by type of relationship partner (stronger for general relationships than for specific partners) and relationship reporter (stronger for self-reported than for informant-reported relationship characteristics). The findings support assumptions of classic and contemporary theories on the influence of social relationships on self-esteem and on the consequences of self-esteem for the relationship domain. In sum, the findings suggest that the link between people’s social relationships and their level of self-esteem is truly reciprocal in all developmental stages across the life span, reflecting a positive feedback loop between the constructs.

Non-Religious Identities and Life Satisfaction: Questioning the Universality of a Linear Link between Religiosity and Well-Being
Non-Religious Identities and Life Satisfaction: Questioning the Universality of a Linear Link between Religiosity and Well-Being. Katharina Pöhls et al. Journal of Happiness Studies, September 26 2019. https://link.springer.com/article/10.1007/s10902-019-00175-x
Abstract: Previous research has frequently found a positive relation between religiosity compared to non-religiosity and psychological well-being. Recent studies have demonstrated differences between types of non-religious individuals and the relevance of a fit between individual (non-)religiosity and characteristics of the country a person is living in. This study combined the previous (partially) competing lines of research for the first time and examined the connection between self-identifying as specifically atheist, non-religious without further distinction, weakly religious, or highly religious and life satisfaction. World Values Survey data of 24 countries worldwide that vary in their social norms of religiosity and societal levels of development were used for a quantitative intercultural comparison (N = 33,879). In contrast to most previous research, a multilevel regression analysis showed no differences between highly religious, indistinct non-religious, and atheist individuals’ level of life satisfaction when the fit between individual (non-)religiosity and country characteristics was included. Weakly religious individuals though were significantly less satisfied with life than highly religious individuals. Thus, our results indicate that only in religious societies, identifying as non-religious/atheist is related to lower life satisfaction. When controlling for the context, a curvilinear relation between (non-)religiosity and life satisfaction emerged. Additionally, atheists differed in their sensitivity towards the social norm of religiosity from indistinct non-religious individuals—their well-being varied dependent on living in a country with many other secular individuals or not. These results demonstrate differences between subgroups of (non-)religious individuals and they call into question a general benefit of religiosity for subjective well-being independent of societal context.

Canada: Similar to the findings in the alcohol literature, the upper 10% of cannabis users accounted for approximately two-thirds of all cannabis consumed in the country
Who consumes most of the cannabis in Canada? Profiles of cannabis consumption by quantity. Russell C. Callaghan et al. Drug and Alcohol Dependence, September 25 2019, 107587. https://doi.org/10.1016/j.drugalcdep.2019.107587
Highlights
• Study pooled Waves 1-3 of the 2018 Canadian National Cannabis Survey (n = 18,900).
• Surveys assessed cannabis use by quantity across seven major cannabis-product types.
• A standard joint measure was created, based on physical production equivalencies.
• The upper 10% of Canadian cannabis users accounted for 66% of all cannabis consumed.
Abstract
Aim: To establish whether the population-level pattern of cannabis use by quantity is similar to the distributions previously reported for alcohol, in which a small subset of drinkers accounts for a majority of total population alcohol consumption.
Method: The current study pooled Waves 1-3 of the 2018 National Cannabis Survey (n = 18,900; 2584 past-three-month cannabis users), a set of stratified, population-based surveys designed to assess cannabis consumption and related behaviors in Canada. Each survey systematically measured self-reported cannabis consumption by quantity across seven of the major cannabis-product types. In order to enable the conversion of self-reported consumption of non-flower cannabis products into a standard joint equivalent (SJE: equal to 0.5 g of dried cannabis), we created conversion metrics for physical production equivalencies across cannabis products.
Results: Similar to the findings in the alcohol literature, study results show that cannabis consumption is highly concentrated in a small subset of users: the upper 10% of cannabis users accounted for approximately two-thirds of all cannabis consumed in the country. Males reported consuming more cannabis by volume than females (approximately 60% versus 40%), with young males (15-34 years old) being disproportionately represented in the heaviest-using subgroups.
Conclusions: Most of the cannabis used in Canada is consumed by a relatively small population of very heavy cannabis users. Future research should attempt to identify the characteristics of the heaviest-using groups, as well as how population-level cannabis consumption patterns relate to the calculus of cannabis-related harms in society.

Positive associations among curiosity lability & depression, & negative ones among curiosity lability & life satisfaction and flourishing; curiosity is higher on days of greater happiness & physical activity
Within‐person variability in curiosity during daily life and associations with well‐being. David M. Lydon‐Staley, Perry Zurn, Danielle S. Bassett. The Journal of Personality, September 13 2019. https://doi.org/10.1111/jopy.12515
Abstract
Objective: Curiosity promotes engagement in novel situations and the accruement of resources that promote well‐being. An open question is the extent to which curiosity lability, the degree to which curiosity fluctuates over short timescales, impacts well‐being.
Method: We use data from a 21‐day daily diary as well as trait measures in 167 participants (mean age = 25.37 years, SD = 7.34) to test (a) the importance of curiosity lability for depression, flourishing, and life satisfaction, (b) day‐to‐day associations among curiosity and happiness, depressed mood, anxiety, and physical activity, and (c) the role of day's mood as a mediator between physical activity and curiosity.
Results: We observe positive associations among curiosity lability and depression, as well as negative associations among curiosity lability and both life satisfaction and flourishing. Curiosity is higher on days of greater happiness and physical activity, and lower on days of greater depressed mood. We find evidence consistent with day's depressed mood and happiness being mediators between physical activity and curiosity.
Conclusions: Greater consistency in curiosity is associated with well‐being. We identify several potential sources of augmentation and blunting of curiosity in daily life and provide support for purported mechanisms linking physical activity to curiosity via mood.
4 DISCUSSION
Curiosity promotes engagement with novel and challenging stimuli and situations, leading to the accruement of resources, and promoting well‐being (Fredrickson & Cohn, 2008). It is through consistently acting on one's curiosity that high trait curiosity is thought to promote well‐being (Kashdan et al., 2018), necessitating a consideration of the extent to which curiosity lability, fluctuations in curiosity over the time scale of days, and a measure of inconsistency in one's curiosity, may undermine well‐being. We quantified between‐person differences in curiosity lability over the course of 21 days and tested the associations between curiosity lability and depression, life satisfaction, and flourishing. Consistent with the hypothesized importance of consistent curiosity in promoting well‐being, individuals with relatively greater fluctuations in curiosity around their average level of curiosity during the daily diary protocol had decreased life satisfaction and increased depression. Notably, the association between curiosity lability and both life satisfaction and depression was significant above and beyond a trait measure of curiosity, indicating the added value of considering dynamics in curiosity for understanding well‐being. A main effect of curiosity lability on flourishing was not observed. Instead, inconsistency in curiosity was associated with lower flourishing only for participants with below average levels of trait curiosity.
After revealing the importance of within‐person fluctuations in curiosity for well‐being, we examined the extent to which happiness, depressed mood, anxiety, and physical activity acted as potential sources of augmentation and blunting of curiosity in daily life. In line with previous laboratory findings (Rodrigue et al., 1987) and perspectives that positive emotions motivate exploration (Diener & Diener, 1996) while negative emotions restrict exploration (Fredrickson, 2004), we observed that days of higher than usual depressed mood were associated with lower than usual curiosity, and that days of higher than usual happiness were associated with higher than usual curiosity. These results suggest that negative associations among depressed mood and curiosity generalize to ecologically valid, naturalistic fluctuations in mood and curiosity occurring during the course of daily life.
Within‐person variability in anxiety was not associated with changes in curiosity. Due in great part to the Latin sense of cura as meticulous, painstaking, even obsessive care (Leigh, 2013), curiosity and anxiety have been densely intertwined historically, promulgating the notion that curiosity “has always an appearance of giddiness, restlessness, and anxiety” (Burke, 1958, p. 31). Early psychological theories proposed that curiosity may result from the identification of contradictions and ambiguities that leads to an unpleasant feeling some have interpreted as anxiety (Berlyne, 1960; Dollard & Miller, 1950; Spielberger & Starr, 1994). Other perspectives view anxiety as a state that interferes with the exploratory behavior characteristic of curiosity (Kashdan et al., 2004). The contrasting associations among anxiety and curiosity may be differentially present prior to curiosity‐driven exploration and during the process of curiosity‐driven engagement with novel stimuli and situations. Testing these distinct pathways will require repeated measures at more fine‐grained timescales than were available in the daily diary reports in the present study.
We replicate previously observed between‐person associations among curiosity and physical activity (Brand et al., 2010), with higher levels of average physical activity across the 21‐day daily diary protocol associated with higher levels of average curiosity. In addition to replicating this between‐person finding, our collection of intensive repeated measures allowed us to disentangle within‐person and between‐person associations among physical activity and curiosity, and to demonstrate that the association among physical activity and curiosity was also evident at the within‐person level, with days of greater than usual physical activity being associated with greater than usual curiosity. Results of the within‐person mediation analyses are consistent with frameworks suggesting that physical activity's association with curiosity is partially mediated via physical activity's effects on positive and depressed mood (Berger & Owen, 1992; Penedo & Dahn, 2005; Rehor et al., 2001). Further study of physical activity using modes, scales, and intensities titrated to disabled bodies, moreover, could deepen and extend the present study to account for a population significantly understudied in the literature on curiosity.
6 CONCLUSIONS
In summary, the present study extends previous examinations of the association among curiosity and well‐being by demonstrating that the extent to which one consistently reports feeling curious during the course of daily life is associated with well‐being. The findings emphasize the importance of considering dynamics in curiosity and, by observing within‐person associations among curiosity, depressed mood, happiness, and physical activity, begin the task of identifying potential sources of augmentation and blunting of curiosity in daily life that may be targeted to realize consistent curiosity.
Abstract
Objective: Curiosity promotes engagement in novel situations and the accruement of resources that promote well‐being. An open question is the extent to which curiosity lability, the degree to which curiosity fluctuates over short timescales, impacts well‐being.
Method: We use data from a 21‐day daily diary as well as trait measures in 167 participants (mean age = 25.37 years, SD = 7.34) to test (a) the importance of curiosity lability for depression, flourishing, and life satisfaction, (b) day‐to‐day associations among curiosity and happiness, depressed mood, anxiety, and physical activity, and (c) the role of day's mood as a mediator between physical activity and curiosity.
Results: We observe positive associations among curiosity lability and depression, as well as negative associations among curiosity lability and both life satisfaction and flourishing. Curiosity is higher on days of greater happiness and physical activity, and lower on days of greater depressed mood. We find evidence consistent with day's depressed mood and happiness being mediators between physical activity and curiosity.
Conclusions: Greater consistency in curiosity is associated with well‐being. We identify several potential sources of augmentation and blunting of curiosity in daily life and provide support for purported mechanisms linking physical activity to curiosity via mood.
4 DISCUSSION
Curiosity promotes engagement with novel and challenging stimuli and situations, leading to the accruement of resources, and promoting well‐being (Fredrickson & Cohn, 2008). It is through consistently acting on one's curiosity that high trait curiosity is thought to promote well‐being (Kashdan et al., 2018), necessitating a consideration of the extent to which curiosity lability, fluctuations in curiosity over the time scale of days, and a measure of inconsistency in one's curiosity, may undermine well‐being. We quantified between‐person differences in curiosity lability over the course of 21 days and tested the associations between curiosity lability and depression, life satisfaction, and flourishing. Consistent with the hypothesized importance of consistent curiosity in promoting well‐being, individuals with relatively greater fluctuations in curiosity around their average level of curiosity during the daily diary protocol had decreased life satisfaction and increased depression. Notably, the association between curiosity lability and both life satisfaction and depression was significant above and beyond a trait measure of curiosity, indicating the added value of considering dynamics in curiosity for understanding well‐being. A main effect of curiosity lability on flourishing was not observed. Instead, inconsistency in curiosity was associated with lower flourishing only for participants with below average levels of trait curiosity.

Childhood experience of parents’ lying is related to lying to parents in adulthood, and to adulthood maladjustments; parenting by lying may negatively impact children’s later psychosocial functioning
Parenting by lying in childhood is associated with negative developmental outcomes in adulthood

Highlights
• Childhood experience of parents’ lying is related to lying to parents in adulthood.
• Childhood experience of parents’ lying is related to adulthood maladjustments.
• Parenting by lying may negatively impact children’s later psychosocial functioning.
Abstract: Parenting by lying refers to the parenting practice of deception to try to control children’s behavioral and affective states. Although the practice is widely observed across cultures, few studies have examined its associations with psychological outcomes in adulthood. The current research fills this gap by sampling 379 young Singaporean adults who reported on their childhood exposure to parenting by lying, their current deceptive behaviors toward parents, and their psychosocial adjustment. Results revealed that the adults who remembered being exposed to higher levels of parenting by lying in childhood showed higher levels of deception toward their parents and higher levels of psychosocial maladjustment. Our findings suggest that parenting by lying may have negative implications for children’s psychosocial functioning later in life.

192 Countries, 2001-2018: The strongest predictors of variation in entrepreneurial activity were normative, with social norms being the most strongly associated with entrepreneurialism & rates of organizational founding
Assenova, Valentina, Why Are Some Societies More Entrepreneurial than Others? Evidence from 192 Countries over 2001-2018 (January 25, 2019). SSRN: http://dx.doi.org/10.2139/ssrn.3449762
Abstract: Why do societies vary in their rates of entrepreneurship and organizational founding? Drawing on the largest available longitudinal sample comprising 192 countries over 2001-2018, I examine the evidence in relation to several explanations, including variation in the density of established organizations, national investment in research and development (R&D), technology transfer to new companies, the quality of science, technology, engineering and math (STEM) education, venture capital (VC) availability, and governmental support and policies for entrepreneurship. Contrary to prevailing theories, there is limited empirical support for these explanations. Rather, the evidence shows that the strongest predictors of cross-national variation in entrepreneurial activity were normative, with social norms being the most strongly associated with entrepreneurialism and rates of organizational founding. This study further examines the relationship between norms and societal culture and finds that more gender-egalitarian societies and societies that value and reward performance and endorse status privileges had on average higher rates of organizational founding, net of differences in national income and economic growth. The paper discusses the implications of these findings in relation to research on the social determinants of entrepreneurship and organizational founding.

Women and men differ in the perception of their technological capabilities, with women having a worse perception of their own skills, although they do not differ in goal achievement
Similarities and Differences between Genders in the Usage of Computer with Different Levels of Technological Complexity. Sabrina Sobieraj, Nicole C. Krämer. Computers in Human Behavior, September 25 2019. https://doi.org/10.1016/j.chb.2019.09.021
Highlights
• Women and men differ in the perception of their technological capabilities
• Women and men do not differ in goal achievement
• Women and men slightly differ in their affect depending on technologies’ complexity
Abstract: Research on technology usage and acceptance has demonstrated that women and men use technology differently, and also differ in their self-perception regarding technology (e.g., women see themselves as less capable). Gender role beliefs, according to which women are expected to be less interested in and less capable of using technologies than men, have been discussed as one major reason for these differences. Such differing attributions of women and men can induce negative experiences in terms of negative feelings and can reinforce the feelings of uncertainty experienced by women. We therefore assume that the usage of technology, especially with increasing complexity, may induce more negative experiences in women than in men. We conducted a 2 (male, female) x 3 (technological complexity) between-subjects lab experiment (N = 148) to examine the interaction between technological complexity and users’ gender. The analyses revealed that women and men differ in the perception of their technological capabilities, but not in goal achievement. Additionally, we found slight gender differences concerning positive affect, but not concerning negative affect, depending on technologies’ complexity.

Piloerection (goosebumps) Is Not a Reliable Physiological Correlate of Awe

“Piloerection (goosebumps) Is Not a Reliable Physiological Correlate of Awe.” OSF
Preprints. September 25. doi:10.31219/osf.io/72j4w
Abstract: In scientific and popular literature, piloerection (e.g. goosebumps) is often described as being related to the experience of awe, though this correlation has not been tested empirically. Using two pre-registered and independently collected samples (N = 233), we examined the objective physiological occurrence of piloerection in response to awe-inducing stimuli. Stimuli were selected to satisfy three descriptors of awe, including perceptual vastness, virtual reality, and expectancy-violating events. The stimuli reliably elicited self-reported awe to a great extent, in line with hypotheses. However, awe-inducing stimuli were not associated with the objective occurrence of piloerection. While participants self-reported high levels of goosebumps and “the chills,” there was no physical evidence of this. These results suggest that piloerection is not reliably connected to the experience of awe—at least using stimuli known to elicit awe in an experimental setting.

A large number of Americans believe their physical health has been harmed by their exposure to politics & even more report that politics has resulted in emotional costs and lost friendships
Friends, relatives, sanity, and health: The costs of politics. Kevin B. Smith, Matthew V. Hibbing, John R. Hibbing. PLoS ONE 14(9), e0221870, September 25, 2019. https://doi.org/10.1371/journal.pone.0221870
Abstract: Political scientists have long known that political involvement exacts costs but they have typically defined these costs in relatively narrow, largely economic terms. Though anecdotal evidence suggests that the costs of politics may in fact extend beyond economics to frayed personal relationships, compromised emotional stability, and even physical problems, no systematic evidence on these broader costs exists. We construct and validate batteries of survey items that delineate the physical, social, and emotional costs of political engagement and administer these items to a demographically representative sample of U.S. adults. The results suggest that a large number of Americans believe their physical health has been harmed by their exposure to politics and even more report that politics has resulted in emotional costs and lost friendships.

Deception Detection: Emotion recognition training was not found to impact on accuracy
Zloteanu, Mircea. 2019. “Emotion Recognition and Deception Detection.” PsyArXiv. September 25. doi:10.31234/osf.io/crzne
Abstract: People hold strong beliefs regarding the role of emotional cues in detecting deception. While research on the diagnostic value of such cues has been mixed, their influence on human veracity judgments should not be ignored. Here, we address the relationship between emotional information and veracity judgments. In Study 1, the role of emotion recognition in the process of detecting naturalistic lies was investigated. Decoders’ accuracy was compared based on differences in trait empathy and their ability to recognize microexpressions and subtle expressions. Accuracy was found to be unrelated to facial cue recognition but negatively related to empathy. In Study 2, we manipulated decoders’ emotion recognition ability and the type of lies they saw: experiential or affective. Decoders either received emotion recognition training, bogus training, or no training. In all scenarios, training was not found to impact on accuracy. Experiential lies were easier to detect than affective lies, but, affective emotional lies were easier to detect than affective unemotional lies. The findings suggest that emotion recognition has a complex relationship with veracity judgments.

Male juvenile rats and laughter: There was evidence that tickling showed rebound and emotional contagion effects
Relationships between play and responses to tickling in male juvenile rats. Tayla Hammond et al. Applied Animal Behaviour Science, September 25 2019, 104879. https://doi.org/10.1016/j.applanim.2019.104879
Highlights
• Solitary but not social play increased prior to and potentially in anticipation of tickling sessions
• There were substantial differences between cohorts in their tickling responses and play behaviour.
• Taking account of cohort there was evidence that tickling showed rebound and emotional contagion effects
• Cohort effects may be explained by differences in physical condition prior to tickling.
Abstract: Play is a putatively positive experience and of key interest to the study of affective state in animals. Rats produce 50 kHz ultrasonic vocalisation (USVs) during positive experiences, including social play and tickling. The tickling paradigm is intended to mimic social play resulting in positively valanced ultrasonic vocalisation (USV) production. We tested two hypotheses on the relationship between tickling and play: that tickling would increase play behaviour or that play behaviour would increase in anticipation of tickling, and that tickling would share some specific properties of play (rebound and emotional contagion of unexposed cage mates). Male Wistar rats (N = 64, with 32 rats/cohort) of 28 days of age were housed in pairs with one rat assigned to be tickled and one as the non-tickled control. Production of 50 kHz USVs and hand-following behaviour was measured. Prior to handling, solitary and social play was recorded for 5 minutes in the home cage. A two-day break in tickling was used to assess a potential rebound increase in responses to tickling. Only one rat within each cage was handled to assess emotional contagion through changes in the behaviour of the cage-mate. Solitary but not social play increased prior to tickling relative to controls (p = 0.01). There were marked differences between cohorts; tickled rats in C2 produced less 50 kHz USVs than those in C1 (p = 0.04) and overall, C2 rats played less than rats in C1 (social p = 0.04 and solitary p < 0.001) and had a lighter start weight on arrival (p = 0.009) compared with cohort 1 (C1). In C1, there was evidence of rebound in USV production (p < 0.001) and a contagious effect of tickling reflected by increased hand-following in cage mates (p = 0.02). We found a positive relationship between start weight and USV responses to tickling (Rs = 0.43, p < 0.001), suggesting that the divergence in USV production may be due to developmental differences between cohorts. The results suggest that the relationship between tickling and play is complex in that tickling only affected solitary and not social play, and that tickling responses showed rebound and contagion effects on cage-mates which were specific to cohort responses to tickling.

People in creative occupations and the entertainment industry – artists (both genders), musicians (males) and actors (males) – were at increased risk of suicide
Occupation-specific suicide risk in England: 2011–2015. Ben Windsor-Shellard and David Gunnell. The British Journal of Psychiatry, Volume 215, Issue 4, October 2019 , pp. 594-599. https://doi.org/10.1192/bjp.2019.69
Abstract
Background: Previous research has documented marked occupational differences in suicide risk, but these estimates are 10 years old and based on potentially biased risk assessments.
Aims: To investigate occupation-specific suicide mortality in England, 2011–2015.
Method: Estimation of indirectly standardised mortality rates for occupations/occupational groups based on national data.
Results: Among males the highest risks were seen in low-skilled occupations, particularly construction workers (standardised mortality ratio [SMR] 369, 95% CI 333–409); low-skilled workers comprised 17% (1784/10 688) of all male suicides (SMR 144, 95% CI 137–151). High risks were also seen among skilled trade occupations (SMR 135 95% CI 130–139; 29% of male suicides). There was no evidence of increased risk among some occupations previously causing concern: male healthcare professionals and farmers. Among females the highest risks were seen in artists (SMR 399, 95% CI 244–616) and bar staff (SMR 182, 95% CI 123–260); nurses also had an increased risk (SMR 123, 95% CI 104–145). People in creative occupations and the entertainment industry – artists (both genders), musicians (males) and actors (males) – were at increased risk, although the absolute numbers of deaths in these occupations were low. In males (SMR 192, 95% CI 165–221) and females (SMR 170, 95% CI 149–194), care workers were at increased risk and had a considerable number of suicide deaths.
Conclusions: Specific contributors to suicide in high-risk occupations should be identified and measures – such as workplace-based interventions – put in place to mitigate this risk. The construction industry seems to be an important target for preventive interventions.

Internet use resulted in better answers, but also in significant and persistent overestimation of information problem-solving ability and performance, even in more accurate postdictive metacognitive judgments
Will using the Internet to answer knowledge questions increase users’ overestimation of their own ability or performance? Stephanie Pieschl. Media Psychology, Sep 24 2019. https://doi.org/10.1080/15213269.2019.1668810
Abstract: Using the Internet is ubiquitous, but not all of the consequences of this habitual technology use are known. Theoretical models and related research suggest that the act of searching for information on the Internet itself may bias users toward overestimating themselves. The current study is the first direct empirical test of this assumption. In a two-by-two design, n = 184 participants were randomly assigned to between-subject Internet or NoInternet conditions in each of two phases: In the Induction Phase 1, participants made predictive metacognitive judgments about their ability to answer a first set of explanatory knowledge questions. In the Target Phase 2, they made predictive and postdictive metacognitive judgments about their ability to answer a second, entirely unrelated set of explanatory knowledge questions and answered two of these questions. Results show that Internet use affected tasks only in the same phase, but not in subsequent unrelated phases. Internet use resulted in better answers, but also in significant and persistent overestimation of information problem-solving ability and performance, even in more accurate postdictive metacognitive judgments. Potential consequences of this side effect of Internet use are discussed such as premature termination of information problem-solving and suboptimal performance.

Abstract: Using the Internet is ubiquitous, but not all of the consequences of this habitual technology use are known. Theoretical models and related research suggest that the act of searching for information on the Internet itself may bias users toward overestimating themselves. The current study is the first direct empirical test of this assumption. In a two-by-two design, n = 184 participants were randomly assigned to between-subject Internet or NoInternet conditions in each of two phases: In the Induction Phase 1, participants made predictive metacognitive judgments about their ability to answer a first set of explanatory knowledge questions. In the Target Phase 2, they made predictive and postdictive metacognitive judgments about their ability to answer a second, entirely unrelated set of explanatory knowledge questions and answered two of these questions.

Laypeople Can Predict Which Social Science Studies Replicate
Hoogeveen, Suzanne, Alexandra Sarafoglou, and Eric-Jan Wagenmakers. 2019. “Laypeople Can Predict Which Social Science Studies Replicate.” PsyArXiv. September 25. doi:10.31234/osf.io/egw9d
Abstract: Large-scale collaborative projects recently demonstrated that several key findings from the social science literature could not be replicated successfully. Here we assess the extent to which a finding’s replication success relates to its intuitive plausibility. Each of 27 high-profile social science findings was evaluated by 233 people without a PhD in psychology. Results showed that these laypeople predicted replication success with above-chance performance (i.e., 58%). In addition, when laypeople were informed about the strength of evidence from the original studies, this boosted their prediction performance to 67%. We discuss the prediction patterns and apply signal detection theory to disentangle detection ability from response bias. Our study suggests that laypeople’s predictions contain useful information for assessing the probability that a given finding will replicate successfully.

Just 4% of participants appeared to use prior research to make probability estimates—most seemed to focus on the latest study, ignoring/discounting prior ones, even when they had more statistics classes
Is One Study as Good as Three? College Graduates Seem to Think So, Even if They Took Statistics Classes. m W Burt Thompson et al. Psychology Learning & Teaching, September 25, 2019. https://doi.org/10.1177/1475725719877590
Abstract: When people interpret the outcome of a research study, do they consider other relevant information such as prior research? In the current study, 251 college graduates read a single brief fictitious news article. The article summarized the findings of a study that found positive results for a new drug. Three versions of the article varied the amount and type of previous research: (a) two prior studies that found the drug did not work, (b) no prior studies of the drug, or (c) two prior studies that found the drug had a positive effect. After reading the article, participants estimated the probability the drug is effective. Average estimates were similar for the three articles, even for participants who reported more statistics experience. Overall, just 4% of participants appeared to use prior research to make probability estimates—most seemed to focus on the latest study, while ignoring or discounting prior studies. Implications for statistics education and reporting are discussed.

Quashing the hopes of personalized antidepressants: "Our findings did not provide empirical support for individual differences in response to antidepressants"
Munkholm, Klaus, Stephanie Winkelbeiner, and Philipp Homan. 2019. “Individual Response to Antidepressants for Depression in Adults – a Simulation Study and Meta-analysis.” PsyArXiv. September 25. doi:10.31234/osf.io/m4aqc
Abstract
Background. The observation that some patients appear to respond better to antidepressants for depression than others encourages the assumption that the effect of antidepressants differs between individuals and that treatment can be personalized. To test this assumption, we compared the outcome variance in the group of patients receiving antidepressants with the outcome variance of the group of patients receiving placebo in randomized controlled trials (RCTs) of adults with major depressive disorder (MDD). An increased variance in the antidepressant group would indicate individual differences in response to antidepressants. In addition, we illustrate in a simulation study why attempts to personalize antidepressant treatment using RCTs might be misguided.
Methods. We first illustrated the variance components of trials by simulating RCTs and crossover trials of antidepressants versus placebo. Second, we analyzed data of a large meta-analysis of antidepressants for depression, including a total of 222 placebo-controlled studies from the dataset that reported outcomes on the 17 or 21 item Hamilton Depression Rating Scale or the Montgomery-Åsberg Depression Rating Scale. We performed inverse variance, random-effects meta-analyses of the variability ratio (VR) between the antidepressant and placebo groups.
Outcomes. The meta-analyses of the VR comprised 345 comparisons of 19 different antidepressants with placebo in a total of 61144 adults with an MDD diagnosis. Across all comparisons, we found no evidence for a larger variance in the antidepressant group compared with placebo overall (VR = 1.00, 95% CI: 0.98; 1.01, I2 = 0%) or for any individual antidepressant.
Interpretation. Our findings did not provide empirical support for individual differences in response to antidepressants.

Adolescent drinking has declined across many developed countries from the turn of the century; we aim to explore existing evidence examining possible reasons for this decline; the main reason could be shifts in parental practices
Why is adolescent drinking declining? A systematic review and narrative synthesis. Rakhi Vashishtha et al. Addiction Research & Theory, Sep 23 2019. https://doi.org/10.1080/16066359.2019.1663831
Abstract
Background: Adolescent drinking has declined across many developed countries from the turn of the century. The aim of this review is to explore existing evidence examining possible reasons for this decline.
Methods: We conducted systematic searches across five databases: Medline, PsycINFO, CINAHL, Informit Health and Scopus. Studies were included if association between declining alcohol consumption and potential explanatory factors were measured over time. Narrative synthesis was undertaken due to substantial methodological heterogeneity in these studies.
Results: 17 studies met the inclusion criteria. Five studies found moderate evidence for changes in parental practices as a potential cause for the decline. Five studies that examined whether alcohol policy changes influenced the decline found weak evidence of association. Three studies explored whether alcohol use has been substituted by illicit substances but no evidence was found. Two studies examined the effect of a weaker economy; both identified increase in adolescent alcohol use during times of economic crisis. One study indicated that changes in exposure to alcohol advertising were positively associated with the decline and another examined the role of immigration of non-drinking populations but found no evidence of association. One study tested participation in organised sports and party lifestyle as a potential cause but did not use robust analytical methods and therefore did not provide strong evidence of association for the decline.
Conclusions: The most robust and consistent evidence was identified for shifts in parental practices. Further research is required using robust analytical methods such as ARIMA modelling techniques and utilising cross-national data.

Hedonic responses to music are the result of connectivity between structures involved in auditory perception as a predictive process, & those involved in the brain's dopaminergic reward system
Musical anhedonia and rewards of music listening: current advances and a proposed model. Amy M. Belfi, Psyche Loui. Annals of the New York Academy of Sciences, September 23 2019. https://doi.org/10.1111/nyas.14241
Abstract: Music frequently elicits intense emotional responses, a phenomenon that has been scrutinized from multiple disciplines that span the sciences and arts. While most people enjoy music and find it rewarding, there is substantial individual variability in the experience and degree of music‐induced reward. Here, we review current work on the neural substrates of hedonic responses to music. In particular, we focus the present review on specific musical anhedonia, a selective lack of pleasure from music. Based on evidence from neuroimaging, neuropsychology, and brain stimulation studies, we derive a neuroanatomical model of the experience of pleasure during music listening. Our model posits that hedonic responses to music are the result of connectivity between structures involved in auditory perception as a predictive process, and those involved in the brain's dopaminergic reward system. We conclude with open questions and implications of this model for future research on why humans appreciate music.
Introduction
The capacity to perceive, produce, and appreciate music, together termed musicality,1 has been a growing topic of interest in the past 20 years of cognitive neuroscience. While most cognitive neuroscience studies on musicality focus on music perception and production skills, there has been a recent explosion of interest in the appreciation of music.2, 3 Multiple research programs in the cognitive neuroscience of music have involved comparing participants with different types and levels of musical training.4-7 However, to cognitive neuroscientists who are not particularly concerned with music, these studies may appear to be highly specialized and of limited interest as they seem to focus on a special population—highly trained musicians. In contrast, studies on the appreciation of music can be thought of as more general and inclusive, encompassing the vast majority of humans regardless of formal musical training.
Humans show knowledge of fundamental musical building blocks, such as rhythm and beat, from as early as 1 day old,8 and as shown from the success of the multibillion‐dollar music industry, humans around the world enjoy music. One of the most frequently reported reasons for listening to music is the overwhelming influence it has on feelings and emotions.9 Music has been deemed an ultimate group bonding activity;10, 11 this is supported by structural features of melody, harmony, and scales that are observed across many cultures,12 as well as the ubiquity of songs that serve social functions, such as lullabies, dance songs, healing songs, and love songs, across cultures.13 Singing and making music together enhance social interactions and group bonding14, 15 and elicit physiological effects that are observable from infancy.16 Even in the few cultures where music is not produced in groups, members of these cultures nevertheless enjoy singing for each other,17 suggesting that the capacity for music enjoyment, that is, the rewarding aspects of music, may be intrinsic to humans as a social species. Together, these lines of research suggest that understanding why humans love music may offer a window into how humans interact in a social environment.
The rapid growth of research on musical enjoyment, specifically in cognitive neuroscience, may also be facilitated in part by recent findings on the role of dopamine in coding for prediction and reward. Since the classic observations that stimulating dopaminergic neurons elicits motivated behavior,18 and that dopaminergic neurons signal changes in the predictability of rewards,19 thousands of studies have identified a set of regions within the human brain that are especially sensitive to reward. These regions center around the midbrain (the ventral tegmental area and substantia nigra (SN)), the dorsal and ventral striatum (VS) (the caudate, putamen, nucleus accumbens (NAcc), and globus pallidus), and the medial prefrontal cortex (mPFC).20 These areas, which we refer to throughout this article as the reward system, are reliably activated during the experience of unconditionally rewarding, evolutionarily salient stimuli, such as food and sex, as well as stimuli that are strongly associated with such rewards, such as money. Findings from the monetary incentive delay task show that cues that predict monetary rewards reliably activate the striatum and mPFC,21 core areas of the reward network. Interestingly, activity in the striatum is also observed when social stimuli (faces) are substituted for monetary rewards,22, 23 suggesting that social and monetary cues tap into “common neural currency” of the reward system.22
The findings that food and sex activate the same reward system can be readily explained as being evolutionarily adaptive: being motivated to seek out these stimuli improves our chances of survival. In contrast, the adaptive value of music—and aesthetic stimuli more generally—is less obvious. Nevertheless, much recent work has shown that music engages the reward system (as reviewed below; see also Ref. 24). While music ranks highly among the pleasures in life,25, 26 recent work has identified a unique condition of people with specific musical anhedonia:27, 28 people who are insensitive to the rewarding aspects of music despite normal hedonic responses to other sensory and aesthetic stimuli, and normal auditory perceptual abilities.29 The existence of this unique population raises many important questions. Some of these questions include:
. The nature versus nurture of musical reward sensitivity: Does musical anhedonia run in families? When and how did it develop? What, if any, genetic underpinnings might predispose an individual toward musical anhedonia? What is its developmental trajectory?
. Domain‐specificity versus domain‐generality of reward sensitivity: Are there specific neural pathways for music reward that are separate from general reward? What are the neural pathways through which specific stimuli (such as music) come to have privileged access to the reward system? What endows a certain stimulus with privileged access to the reward system?
. Psychological associations and clinical comorbidity: What are the associations between musical anhedonia and psychological traits, both in the normal range (e.g., big five personality traits) and clinical populations? What is the comorbidity between musical anhedonia and personality, mood, and communication disorders?
. The evolution of music: To what extent do nonhuman animals also show reward sensitivity to music? Have there been people with musical anhedonia for as long as there has been music? By extension, if people with musical anhedonia have survived for generations with no apparent disadvantage alongside the rest of the population who have normal reward sensitivity to music, then the lack of reward sensitivity to music seems not to affect their survival. If this is the case, then why do we seek out music?
Here, we review the recent cognitive neuroscience evidence for musical engagement of the reward system, as well as an extreme end of the spectrum of individual differences in sensitivity to music reward in specific musical anhedonia. Based on our review of the literature, we propose a model that accounts for the nature of the auditory access to the human reward system, and its disruption in musical anhedonia.
The effect of close elections on the life expectancy of politicians: Winners outlive losers by over a year, on average
Run for your life? The effect of close elections on the life expectancy of politicians. Mark Borgschulte, Jacob Vogler. Journal of Economic Behavior & Organization, September 24 2019. https://doi.org/10.1016/j.jebo.2019.09.003
Highlights
• Examine effect of winning or losing a close election on the life expectancy of candidates.
• Regression discontinuity design estimated using newly-collected data on winning and losing candidates for governor, senator, and representative in the United States.
• Winners outlive losers by over a year, on average.
• Largest effects for governors and candidates who run later in US history.
• No discernable effect of stress on life expectancy.
Abstract: We estimate the causal effect of election to political office on natural lifespan using a regression discontinuity design and a novel dataset of winning and losing candidates for US governor, senator, and House representative. We find that candidates gain over a year of life from winning a close election. The effect is strongest for governors, and has grown larger over the course of US history. We also examine the effect of stress experienced in office, finding that serving in more challenging situations is not associated with reduced lifespan.

German middle-aged men having ≥2 children, higher frequency of solo-masturbation, perceived importance of sexuality, & higher sexual self-esteem were less likely to have low sexual desire
Meissner VH, Schroeter L, Köhn F-M, et al. Factors Associated with Low Sexual Desire in 45-Year-Old Men: Findings from the German Male Sex-Study. J Sex Med Volume 16, Issue 7, July 2019, Pages 981-991. https://www.sciencedirect.com/science/article/pii/S1743609519311622
Abstract
Introduction Although low sexual desire is 1 of the most common sexual dysfunctions in men, there is a lack of studies investigating associated factors in large, population-based samples of middle-aged men.
Aim To survey the prevalence of low sexual desire in a population-based sample of 45-year-old German men and to evaluate associations with a broad set of factors.
Methods Data were collected between April 2014–April 2016 within the German Male Sex-Study. Participants were asked to fill out questionnaires about 6 sociodemographic, 5 lifestyle, and 8 psychosocial factors, as well as 6 comorbidities and 4 factors of sexual behavior. Simple and multiple logistic regressions were used to assess potential explanatory factors.
Main Outcome Measures We found a notable prevalence of low sexual desire in middle-aged men and detected associations with various factors.
Results 12,646 men were included in the analysis, and prevalence of low sexual desire was 4.7%. In the multiple logistic regression with backward elimination, 8 of 29 factors were left in the final model. Men having ≥2 children, higher frequency of solo-masturbation, perceived importance of sexuality, and higher sexual self-esteem were less likely to have low sexual desire. Premature ejaculation, erectile dysfunction, and lower urinary tract symptoms were associated with low sexual desire.
Clinical Implications Low sexual desire is common in middle-aged men, and associating factors that can potentially be modified should be considered during assessment and treatment of sexual desire disorders.
Strengths & Limitations The strength of our study is the large, population-based sample of middle-aged men and the broad set of assessed factors. However, because of being part of a prostate cancer screening trial, a recruiting bias is arguable.
Conclusion Our study revealed that low sexual desire among 45-year-old men is a common sexual dysfunction, with a prevalence of nearly 5% and might be affected by various factors, including sociodemographic and lifestyle factors, as well as comorbidities and sexual behavior.

Theories link threat with right-wing political beliefs; our findings show that political beliefs and perceptions of threat are linked, but that the relationship is nuanced
Brandt, Mark J., Felicity M. Turner-Zwinkels, Beste Karapirinler, Florian van Leeuwen, Michael Bender, Yvette van Osch, and Byron G. Adams. 2019. “The Association Between Threat and Politics Depends on the Type of Threat, the Political Domain, and the Country.” PsyArXiv. September 24. doi:10.31234/osf.io/e9uk7
Abstract: Theories link threat with right-wing political beliefs. We use the World Values Survey (72,836 participants) to test how different types of threat (economic, violence, and surveillance) are associated with different types of political beliefs (social, economic, and political identification) across 42 different countries. The association between threat and political beliefs depends on the type of threat, the type of political beliefs, and the country. Economic threats tended to be associated with more left-wing economic beliefs, violence threats tended to be associated with more general right-wing beliefs, and surveillance threats tended to be associated with more right-wing economic beliefs and more left-wing social beliefs. Additional analyses explored how 24 country characteristics might help explain variation in the threat-political beliefs association; however, these analyses identified few cross-country characteristics that consistently helped. Our findings show that political beliefs and perceptions of threat are linked, but that the relationship is nuanced.

There is no number sense as traditionally conceived; neural substrates of number sense are more widely distributed than common consensus says, complicating the neurobiological evidence linking number sense to numerical abilities
Challenging the neurobiological link between number sense and symbolic numerical abilities. Eric D. Wilkey. Daniel Ansari. Annals of the New York Academy of Sciences, September 23 2019. https://doi.org/10.1111/nyas.14225
Abstract: A significant body of research links individual differences in symbolic numerical abilities, such as arithmetic, to number sense, the neurobiological system used to approximate and manipulate quantities without language or symbols. However, recent findings from cognitive neuroscience challenge this influential theory. Our current review presents an overview of evidence for the number sense account of symbolic numerical abilities and then reviews recent studies that challenge this account, organized around the following four assertions. (1) There is no number sense as traditionally conceived. (2) Neural substrates of number sense are more widely distributed than common consensus asserts, complicating the neurobiological evidence linking number sense to numerical abilities. (3) The most common measures of number sense are confounded by other cognitive demands, which drive key correlations. (4) Number sense and symbolic number systems (Arabic digits, number words, and so on) rely on distinct neural mechanisms and follow independent developmental trajectories. The review follows each assertion with comments on future directions that may bring resolution to these issues.

How Stress Affects Performance and Competitiveness Across Gender
How Stress Affects Performance and Competitiveness Across Gender. Jana Cahlíková, Lubomír Cingl, Ian Levely. Management Science, Jul 16 2019. https://doi.org/10.1287/mnsc.2019.3400
Abstract: Because many key career events, such as examinations and interviews, involve competition and stress, gender differences in response to these factors could help to explain the labor market gender gap. In a laboratory experiment, we manipulate psychosocial stress using the Trier Social Stress Test and confirm that this is effective by measuring salivary cortisol level and heart rate. Subjects perform in a real-effort task under both tournament and piece-rate incentives, and we elicit willingness to compete. We find that women under heightened stress perform worse than women in the control group when compensated with tournament incentives, whereas there is no treatment difference under piece-rate incentives. For men, stress does not affect output under competition or under piece rate. The gender gap in willingness to compete is not affected by stress, but stress decreases competitiveness overall, which is related to performance for women. Our results could explain gender differences in performance under competition, with implications for hiring practices and incentive structures in firms.

Disagreeable men produce higher-quality ejaculates: A Preliminary but Methodologically Improved Investigation of the Relationships Between Major Personality Dimensions and Human Ejaculate Quality
A Preliminary but Methodologically Improved Investigation of the Relationships Between Major Personality Dimensions and Human Ejaculate Quality. Tara DeLecce et al. [in press, Personality and Individual Differences, September 2019]. toddkshackelford.com/downloads/Delecce-et-al-PAID.pdf
Abstract: Some research has reported relationships between personality dimensions and ejaculate quality, but this research has methodological limitations. In the current study, we investigated the relationships between six major personality dimensions and ejaculate quality in a design that offered several methodological improvements over previous research. Forty-fivefertile men provided two masturbatory ejaculates and completed a measure ofpersonality (HEXACO-60) assessing honesty-humility, emotionality, extraversion, agreeableness, conscientiousness, and openness to experience. Agreeablenesswas the only personality dimension associated with ejaculate quality,aftercontrolling statistically for participant age, Body Mass Index, and abstinence duration, and this association was negative. However, once the covariates of BMI, age, and abstinence duration were included in a hierarchical regression (along with the six personality dimensions), agreeableness was no longer a statistically significant predictor of ejaculate quality, although the direction of the relationship remained negative. The current study adds to previous research documenting that psychological attributes—including major dimensions of personality—may be associated with ejaculate quality. We highlight limitations of the current research and identify directions for future study.

Abstract: Some research has reported relationships between personality dimensions and ejaculate quality, but this research has methodological limitations. In the current study, we investigated the relationships between six major personality dimensions and ejaculate quality in a design that offered several methodological improvements over previous research. Forty-fivefertile men provided two masturbatory ejaculates and completed a measure ofpersonality (HEXACO-60) assessing honesty-humility, emotionality, extraversion, agreeableness, conscientiousness, and openness to experience. Agreeablenesswas the only personality dimension associated with ejaculate quality,aftercontrolling statistically for participant age, Body Mass Index, and abstinence duration, and this association was negative. However, once the covariates of BMI, age, and abstinence duration were included in a hierarchical regression (along with the six personality dimensions), agreeableness was no longer a statistically significant predictor of ejaculate quality, although the direction of the relationship remained negative. The current study adds to previous research documenting that psychological attributes—including major dimensions of personality—may be associated with ejaculate quality. We highlight limitations of the current research and identify directions for future study.

Greta Thunberg's zeal, as the press summarized her speech at the UN Climate Summit, Sep 23, 2019 — updated Jan 2020
Greta Thunberg's character, as the press summarized her speech at the UN Climate Summit, Sep 23, 2019:
At the World Economic Forum annual meeting in Davos, Jan 2020:
"How dare you. You have stolen my dreams and my childhood with your empty words."
"This is all wrong. I shouldn’t be up here. I should be back in school on the other side of the ocean. Yet you all come to us young people for hope. How dare you."
"People are suffering. People are dying and dying ecosystems are collapsing. We are in the beginning of a mass extinction, and all you can talk about is the money and fairy tales of eternal economic growth," she said Monday, as she fought back tears. "How dare you! For more than 30 years the science has been crystal clear."
"You are failing us but young people are starting to understand your betrayal."
“The eyes of all future generations are upon you and if you choose to fail us, I say we will never forgive you.”
At the World Economic Forum annual meeting in Davos, Jan 2020:
“Our house is still on fire. Your inaction is fueling the flames by the hour, and we are telling you to act as if you loved your children above all else.”
Greetings in wild chimpanzees: Signals of submission (the greetings are started by the low-position individual)
Social relationships and greetings in wild chimpanzees (Pan troglodytes): use of signal combinations. Eva Maria Luef, Simone Pika. Primates, September 24 2019. https://link.springer.com/article/10.1007/s10329-019-00758-5
Abstract: Signals of submission, so-called ‘greetings’, represent an important tool for the regulation of social life in primates. In chimpanzees, vocalizations and gestures are commonly employed to communicate greetings, however, the topic of signal complexity (i.e., combinations of signals) during greeting instances has been neglected by research to date. Here, we investigate combinatorial possibilities in vocal greetings in a free-ranging group of chimpanzees (Pan troglodytes) and study how greeter sex, rank relationship between an interacting pair, and strength of the social bond of a greeting dyad influence signal complexity. Results show that the social bond and the dominance distance between individuals engaged in a greeting bout are important determiners for vocal combinations. The findings indicate that greeting signals in chimpanzees, like other vocal signals of the species, can become subject to social influences.

While praise from a manager has no effect, criticism negatively impacts workers' job satisfaction & perception of the task's importance; when female managers give opinion, the negative effects double for both male & female workers
Do Workers Discriminate against Female Bosses? Martin Abel. IZA Discussion Papers No. 12611, September 2019. https://www.iza.org/publications/dp/12611/do-workers-discriminate-against-female-bosses
Abstract: I hire 2,700 workers for a transcription job, randomly assigning the gender of their (fictitious) manager and provision of performance feedback. While praise from a manager has no effect, criticism negatively impacts workers' job satisfaction and perception of the task's importance. When female managers, rather than male, deliver this feedback, the negative effects double in magnitude. Having a critical female manager does not affect effort provision but it does lower workers' interest in working for the firm in the future. These findings hold for both female and male workers. I show that results are consistent with gendered expectations of feedback among workers. By contrast, I find no evidence for the role of either attention discrimination or implicit gender bias.
