Sugar daddy u: human capital investment and the university-based supply of ‘romantic arrangements’. Franklin G. Mixon. Applied Economics, https://doi.org/10.1080/00036846.2018.1524129
Abstract: To deal with the financial hardships associated with rising college tuition, many female college students in the U.S. are turning to risqué forms of financing human capital investments, such as agreeing to potentially lucrative ‘romantic arrangements’ with older males, referred to as ‘sugar daddies,’ through the largest Internet-based club in the industry. Yet despite this recent trend, there is a relative paucity of published academic research on the economics of such behaviour. Using data from the more than 220 nationally ranked (by U.S. News & World Report’s America’s Best Colleges) colleges and universities in the U.S., presents results from both Poisson and scaled Poisson estimation suggesting that large, high-cost universities that are located in larger cities or where unemployment rates are higher lead the nation in the number of female students choosing such romantic arrangements in order to fund higher education. Moreover, those institutions that are chosen by more physically attractive female students, and those that enrol a higher percentage of female students, are also generating greater numbers of female student entrants into the sugar daddy industry. Each of these findings has implications for the human capital literature and the growing body of academic literature on the economics of beauty.

Among primates, only humans have a maximum lifespan significantly longer than 50 years, & only human female life history includes a significant post-fertile stage of life; happens also in other long-lived taxa (resident killer & short-finned pilot whales)
Pavelka M.S.M., Brent L.J.N., Croft D.P., Fedigan L.M. (2018) Post-Fertile Lifespan in Female Primates and Cetaceans. In: Kalbitzer U., Jack K. (eds) Primate Life Histories, Sex Roles, and Adaptability. Developments in Primatology: Progress and Prospects. Springer. https://link.springer.com/chapter/10.1007/978-3-319-98285-4_3
Abstract: Popular and scientific interest in menopause in humans has led to an increased interest in the extent of post-fertile life in other animals, particularly in long-lived social species such as other primates and cetaceans. Information on maximum lifespan achieved and age at last birth are available from long-term observations of known individuals from 11 primate species in the wild. Comparable information from wild cetaceans are more difficult to obtain; however there are relevant fisheries data, as well as a small number of long-term individual-based studies. Using post-reproductive representation (PrR) as a population measure of post-fertile lifespan that allows comparisons across populations and species, this review confirms that among primates, only humans have a maximum lifespan significantly longer than 50 years, and only human female life history includes a significant post-fertile stage of life. We conclude that although a prolonged post-fertile stage of life is very rare in mammals, it does occur in some exceptionally long-lived taxa, such as humans and resident killer and short-finned pilot whales. Thus menopause evolved independently at least three times in mammals, and the reasons for its evolution may differ in different lineages.

Moral Polarization and Out-party Hate in the US Political Context
Tappin, Ben M., and Ryan McKay. 2018. “Moral Polarization and Out-party Hate in the US Political Context.” PsyArXiv. November 2. doi:10.31234/osf.io/4fxb3
Abstract: Affective polarization describes the phenomenon whereby people identifying as Republican or Democrat tend to view opposing partisans negatively and co-partisans positively. Though extensively studied, there remain important gaps in scholarly understanding of affective polarization. In particular, (i) how it relates to the distinct behavioural phenomena of in-party “love” vs. out-party “hate”; and (ii) to what extent it reflects a generalized evaluative disparity between partisans vs. a domain-specific disparity in evaluation. Here, we report the results of an investigation that bears on both of these questions. Specifically, drawing on recent theoretical and empirical trends in political science and psychology, we hypothesize that moral polarization—the tendency to view opposing partisans’ moral character negatively, and co-partisans’ moral character positively—is associated with behavioural expressions of out-party hate. We test this hypothesis in two preregistered studies comprising behavioural measures and large convenience samples of US partisans (total N=1354). Our results strike an optimistic chord: Taken together, they suggest that the hypothesized association is probably small and somewhat tenuous. Though moral polarization per se was large—likely exceeding prior estimates of generalized affective polarization—even the most morally polarized partisans appeared reluctant to engage in a mild form of out-party hate behaviour. These findings converge with recent evidence that polarization—moral or otherwise—has yet to translate into the average US partisan wanting to actively harm their out-party counterparts.

Abstract: This paper describes evidence suggesting that science curiosity counteracts politically biased information processing. This finding is in tension with two bodies of research. The first casts doubt on the existence of “curiosity” as a measurable disposition. The other suggests that individual differences in cognition related to science comprehension - of which science curiosity, if it exists, would presumably be one - do not mitigate politically biased information processing but instead aggravate it. The paper describes the scale-development strategy employed to overcome the problems associated with measuring science curiosity. It also reports data, observational and experimental, showing that science curiosity promotes open-minded engagement with information that is contrary to individuals’ political predispositions. We conclude by identifying a series of concrete research questions posed by these results.

Better‐looking respondents give more morally permissive responses to most questions relating to sex; for issues not directly related to sexual opportunities, however, attractiveness does not predict significantly more acceptant attitudes
Good Looks as a Source of Moral Permissiveness. Robert Urbatsch. Social Science Quarterly, https://doi.org/10.1111/ssqu.12544
Abstract
Objective: Establishing what leads people to particular moral beliefs is complicated by potential predictors being themselves caused by moral attitudes. This problem is less acute when considering the effects of good looks, which, by expanding sexual opportunities, shift incentives for beliefs regarding the morality of sexual activities.
Methods: Regressions predict responses to morality‐related questions in the 2016 General Social Survey and the 1972 National Election Study, which included interviewer (i.e., not self‐generated) evaluations of respondents’ looks. These questions concern various actions’ moral acceptability regardless of legality, as well as policy positions on issues including gay marriage and marijuana legalization.
Results: Better‐looking respondents give more morally permissive responses to most questions relating to sex. For issues not directly related to sexual opportunities, however, attractiveness does not predict significantly more acceptant attitudes.
Conclusion: Good‐looking people generally are more acceptant of those indulgences that they have disproportionate opportunities for, highlighting the role of opportunism in the formation of moral and political attitudes.

Tentative support for the hypothesis that belief in free will increases support for economic inequality; but attempts to experimentally manipulate belief in free will are often underpowered to detect an overall change in a dependent variable
Mercier, Brett G., Dylan Wiwad, Paul Piff, Lara aknin, Angela R. Robinson, and Azim Shariff. 2018. “Does Belief in Free Will Increase Support for Economic Inequality?.” PsyArXiv. November 2. doi:10.31234/osf.io/k45ud
Abstract: In five studies, we test whether belief in free will influences support for economic inequality. Study 1 shows that on a country-level, belief in free will is correlated with support for economic inequality. Study 2 demonstrates that individuals with stronger belief in free will are more likely to support inequality. In Studies 3 and 4, we manipulate belief in free will and find mixed results. We do not find evidence that the manipulation produces an overall change in support for inequality. However, we do find evidence that the data are consistent with a mediation model where the manipulation has an indirect effect on support for inequality through a change in belief in free will. Study 5 finds that people report that they would be more willing to support inequality in a hypothetical universe where free will exists compared to one where it does not. Our results provide tentative support for the hypothesis that belief in free will increases support for economic inequality. Additionally, our research illustrates how attempts to experimentally manipulate mediating variables, such as belief in free will, are often underpowered to detect an overall change in a dependent variable.
Abstract: In five studies, we test whether belief in free will influences support for economic inequality. Study 1 shows that on a country-level, belief in free will is correlated with support for economic inequality. Study 2 demonstrates that individuals with stronger belief in free will are more likely to support inequality. In Studies 3 and 4, we manipulate belief in free will and find mixed results. We do not find evidence that the manipulation produces an overall change in support for inequality. However, we do find evidence that the data are consistent with a mediation model where the manipulation has an indirect effect on support for inequality through a change in belief in free will. Study 5 finds that people report that they would be more willing to support inequality in a hypothetical universe where free will exists compared to one where it does not. Our results provide tentative support for the hypothesis that belief in free will increases support for economic inequality.

Women's chemosignals of high fertility increase mating motivation among man, encouraging them to act in a cooperative manner toward others, a response that may highlight their attractive qualities and thus attract mates
Women's fertility cues affect cooperative behavior: Evidence for the role of the human putative chemosignal estratetraenol. Chen Oren, Simone G. Shamay-Tsoory. Psychoneuroendocrinology, https://doi.org/10.1016/j.psyneuen.2018.10.028
Highlights
• We examined the effect of women's chemosignals of fertility on men's cooperation.
• Men exposed to women's chemosignals of fertility were more cooperative.
• Estratetraenol increased men's tendency to apply a cooperative strategy as well.
• The results support the notion that chemosignals communicating fertility may affect mating -related behaviors among men.
• Estratetraenol is perhaps a biological agent underlying the effects of women's fertility chemosignals.
Abstract: Previous studies demonstrating that women’s body odor during ovulation is perceived as more attractive suggest that exposure to women’s chemosignals of high fertility increases mating motivation. Building on previous evidence showing that cooperative behaviors are perceived as attractive, in the current study we investigated whether chemosignals of women's fertility affect men's tendency to behave cooperatively. In the first experiment we found that in the presence of women's body odor during ovulation, men increase their tendency to apply a cooperative strategy, while their tendency to apply an individualistic strategy decreases. To examine the mechanism underlying this effect, we tested a different sample of men exposed to the putative human pheromone estratetraenol (estra-1,3,5(10),16-tetraen-3-ol) or to a control solution. Exposure to estratetraenol compared with control yielded strikingly similar effects of increased cooperation. The results indicate that women's chemosignals of high fertility increase mating motivation among man, encouraging them to act in a cooperative manner toward others, a response that may highlight their attractive qualities and thus attract mates. We further conclude that estratetraenol may serve as one of the biological agents that mediate the behavioral effects of women's chemosignals of fertility on social behavior.

Researchers frequently make inappropriate requests to statisticians: Removing/altering data to support the hypothesis; interpreting the findings on the basis of expectation, not results; not reporting the presence of key missing data; & ignoring violations of assumptions
Researcher Requests for Inappropriate Analysis and Reporting: A U.S. Survey of Consulting Biostatisticians. Min Qi Wang, Alice F. Yan, Ralph V. Katz. Annals of Internal Medicine, http://annals.org/aim/article-abstract/2706170/researcher-requests-inappropriate-analysis-reporting-u-s-survey-consulting-biostatisticians
Abstract
Background: Inappropriate analysis and reporting of biomedical research remain a problem despite advances in statistical methods and efforts to educate researchers.
Objective: To determine the frequency and severity of requests biostatisticians receive from researchers for inappropriate analysis and reporting of data during statistical consultations.
Design: Online survey.
Setting: United States.
Participants: A randomly drawn sample of 522 American Statistical Association members self-identifying as consulting biostatisticians.
Measurements: The Bioethical Issues in Biostatistical Consulting Questionnaire soliciting reports about the frequency and perceived severity of specific requests for inappropriate analysis and reporting.
Results: Of 522 consulting biostatisticians contacted, 390 provided sufficient responses: a completion rate of 74.7%. The 4 most frequently reported inappropriate requests rated as “most severe” by at least 20% of the respondents were, in order of frequency, removing or altering some data records to better support the research hypothesis; interpreting the statistical findings on the basis of expectation, not actual results; not reporting the presence of key missing data that might bias the results; and ignoring violations of assumptions that would change results from positive to negative. These requests were reported most often by younger biostatisticians.
Limitations: The survey provides information on the reported frequency of inappropriate requests but not on how such requests were handled or whether the requests reflected researchers' maleficence or inadequate knowledge about statistical and research methods. In addition, other inappropriate requests may have been made that were not prespecified in the survey.
Conclusion: This survey suggests that researchers frequently make inappropriate requests of their biostatistical consultants regarding the analysis and reporting of their data. Understanding the reasons for these requests and how they are handled requires further study.

Distortions of perceived volume and length of body parts
Distortions of perceived volume and length of body parts. Renata Sadibolova, Elisa R. Ferrè, Sally A. Linkenauger, Matthew R. Longo. Cortex, https://doi.org/10.1016/j.cortex.2018.10.016
Abstract: We experience our body as a 3D, volumetric object in the world. Measures of our conscious body image, in contrast, have investigated the perception of body size along one or two dimensions at a time. There is, thus, a discrepancy between existing methods for measuring body image and our subjective experience of having 3D body. Here we assessed in a sample of healthy adults the perception of body size in terms of its 1D length and 3D volume. Participants were randomly assigned to two groups using different measuring units (other body part and non-body object). They estimated how many units would fit in a perceived size of body segments and the whole body. The patterns of length and volume misperception across judged segments were determined as their perceived size proportional to their actual size. The pattern of volume misperception paints the representation of 3D body proportions resembling those of a somatosensory homunculus. The body parts with a smaller actual surface area relative to their volume were underestimated more. There was a tendency for body parts underestimated in volume to be overestimated in length. Perceived body proportions thus changed as a function of judgement type while showing a similarity in magnitude of the absolute estimation error, be it an underestimation of volume or overestimation of length. The main contribution of this study is assessing the body image as a 3D body representation, and thus extending beyond the conventional ‘allocentric’ focus to include the body on the inside. Our findings highlight the value of studying the perceptual distortions “at the baseline”, i.e. in healthy population, so as to advance the understanding of the nature of perceptual distortions in clinical conditions.

Recent claims that people spend 40-50% of their waking lives mind wandering have become widely accepted & frequently cited; such simple quantitative estimates are misleading & potentially meaningless without serious qualification
Seli, Paul, Roger E. Beaty, James A. Cheyne, Daniel Smilek, and Daniel L. Schacter. 2018. “How Pervasive Is Mind Wandering, Really?.” PsyArXiv. February 26. doi:10.31234/osf.io/9pruj
Abstract: Recent claims that people spend 40-50% of their waking lives mind wandering (MW) (Killingsworth & Gilbert, 2010; Kane et al. 2007) have become widely accepted and frequently cited. While acknowledging attention to be inconstant and wavering, and MW to be ubiquitous, we argue and present evidence that such simple quantitative estimates are misleading and potentially meaningless without serious qualification. MW estimates requiring dichotomous judgments of inner experience rely on questionable assumptions about how such judgments are made and the resulting data do not permit straightforward interpretations. We present evidence that estimates of daily-life MW vary dramatically depending on response options provided. Offering participants a range of options in estimating task engagement yielded variable MW estimates, from approximately 60% to 10%, depending on assumptions made about how observers make introspective judgments about their MW experiences and how they understand what it means to be on- or off-task.

Congenital Amusia: Understanding of the Musical Mind and Brain
Lee, Harin. 2018. “Congenital Amusia: Understanding of the Musical Mind and Brain.” PsyArXiv. November 1. doi:10.31234/osf.io/xbwfq
Abstract: The current paper aims to provide a comprehensive review of some of the recent researches on congenital amusia, demonstrating how the behavioural, brain-imaging, and genetic studies have extended our understanding of the musical mind and brain. Moreover, it discusses the gaps in the literature that needs to be addressed in future research.

Peretz and her colleagues (2007) investigated 9 large families of amusic probands with 71 members with matched control of 10 families with 75 members. The study showed that the disorder is a defect in pitch discrimination but not timing in music, and it is heritable. While the prevalence of the disorder was only 3% among first-degree relatives of control families, 39% was present in the amusic families. In a twin study of 136 monozygotic and 148 dizygotic twin pairs, participants were asked to discriminate the wrong note in a well-known song melody, and genetic model-fitting showed that shared genes were greater determinant than shared environment with estimate of 70 to 80% heritability (Drayna, Manichaikul, de Lange, Snieder, & Spector, 2001). Likewise, some studies argue that individuals’ musicality in general are more dependent to genetic basis compared to number of practice hours in the context of musical achievement (Peretz, 2016). Even the motivation to commit more hours of practice seems to be genetically influenced. The topic of whether musicality is innate or shaped through the environment is an on-going debate.
Nevertheless, recent studies have also demonstrated that amusia can be improved through laboratory training and raises a more interesting question (Liu, Jiang, Francart, Chan, & Wong, 2017; Whiteford & Oxenham, 2017, 2018). In a study conducted by Whiteford and Oxenham (2017), 20 amusics and matched pair of controls undertook four sessions to train in pitch-discrimination task. After the training, 11 of the amusics no longer met the criteria of MBEA and one year follow up test showed that the improvement is maintained (Whiteford & Oxenham, 2018). This is controversial to the previous findings that amusia is a life-long deficit and questions the current diagnosis of MBEA and whether the disorder is influenced by genetics.

Identification of depression subtypes and relevant brain regions using a data-driven approach
Identification of depression subtypes and relevant brain regions using a data-driven approach.

Scientific Reports, volume 8, Article number: 14082 (2018). https://www.nature.com/articles/s41598-018-32521-z
Abstract: It is well known that depressive disorder is heterogeneous, yet little is known about its neurophysiological subtypes. In the present study, we identified neurophysiological subtypes of depression related to specific neural substrates. We performed cluster analysis for 134 subjects (67 depressive subjects and 67 controls) using a high-dimensional dataset consisting of resting state functional connectivity measured by functional MRI, clinical questionnaire scores, and various biomarkers. Applying a newly developed, multiple co-clustering method to this dataset, we identified three subtypes of depression that are characterized by functional connectivity between the right Angular Gyrus (AG) and other brain areas in default mode networks, and Child Abuse Trauma Scale (CATS) scores. These subtypes are also related to Selective Serotonin-Reuptake Inhibitor (SSRI) treatment outcomes, which implies that we may be able to predict effectiveness of treatment based on AG-related functional connectivity and CATS.

Maternal Age and Child Development: Each year the mother delays a first birth is associated with an increase in school achievement & a similar-sized reduction in behavior problems
Maternal Age and Child Development. Greg J. Duncan, Kenneth T. H. Lee, Maria Rosales-Rueda, Ariel Kalil. Demography, https://link.springer.com/article/10.1007/s13524-018-0730-3
Abstract: Although the consequences of teen births for both mothers and children have been studied for decades, few studies have taken a broader look at the potential payoffs—and drawbacks—of being born to older mothers. A broader examination is important given the growing gap in maternal ages at birth for children born to mothers with low and high socioeconomic status. Drawing data from the Children of the NLSY79, our examination of this topic distinguishes between the value for children of being born to a mother who delayed her first birth and the value of the additional years between her first birth and the birth of the child whose achievements and behaviors at ages 10–13 are under study. We find that each year the mother delays a first birth is associated with a 0.02 to 0.04 standard deviation increase in school achievement and a similar-sized reduction in behavior problems. Coefficients are generally as large for additional years between the first and given birth. Results are fairly robust to the inclusion of cousin and sibling fixed effects, which attempt to address some omitted variable concerns. Our mediational analyses show that the primary pathway by which delaying first births benefits children is by enabling mothers to complete more years of schooling.

Gay females are happier cohabiting, whereas marriage has a stronger well-being effect on gay males
Subjective Well-being and Partnership Dynamics: Are Same-Sex Relationships Different? Shuai Chen, Jan C. van Ours. Demography, https://link.springer.com/article/10.1007/s13524-018-0725-0
Abstract: We analyze Dutch panel data to investigate whether partnership has a causal effect on subjective well-being. As in previous studies, we find that, on average, being in a partnership improves well-being. Well-being gains of marriage are larger than those of cohabitation. The well-being effects of partnership formation and disruption are symmetric. We also find that marriage improves well-being for both younger and older cohorts, whereas cohabitation benefits only the younger cohort. Our main contribution to the literature is on well-being effects of same-sex partnerships. We find that these effects are homogeneous to sexual orientation. Gender differences exist in the well-being effects of same-sex partnerships: females are happier cohabiting, whereas marriage has a stronger well-being effect on males.

Testing the Kundera Hypothesis: Does Every Woman (But Not Every Man) Prefer Her Child to Her Mate? Almost.
Testing the Kundera Hypothesis: Does Every Woman (But Not Every Man) Prefer Her Child to Her Mate? Carlos Hernández Blasi, Laura Mondéjar. Evolutionary Psychology, https://doi.org/10.1177/1474704918808864
Abstract: The context of a famous novel by Milan Kundera (Immortality) suggests that when faced with a life-or-death situation, every woman would prefer to save her child than her husband, left hanging whether every man would do the same. We labeled this as the Kundera hypothesis, and the purpose of this study was to test it empirically as we believe it raises a thought-provoking question in evolutionary terms. Specifically, 197 college students (92 women) were presented a questionnaire where they had to make different decisions about four dilemmas about who to save (their mate or their offspring) in two hypothetical life-or-death situations: a home fire and a car crash. These dilemmas involved two different mate ages (a 25- or a 40-year-old mate) and two offspring ages (1- or a 6-year-old child). For comparative purposes, we also included complementary life-or-death dilemmas on both a sibling and an offspring, and a sibling and a cousin. The results generally supported the Kundera hypothesis: Although the majority of men and women made the decision to save their offspring instead of their mate, about 18% of men on average (unlike the 5% of women) consistently decided to save their mate across the four dilemmas in the two life-or-death situations. These data were interpreted with reference to Hamilton’s inclusive fitness theory, the preferential role of women as kin keepers, and the evolution of altruism toward friends and mates.

Hot Hand Fallacy & Robust Evidence That Belief in the Hot Hand Is Justified, and that expert observers can predict which shooters have a tendency to become hot
Miller, Joshua B., and Adam Sanjurjo. 2018. “A Cold Shower for the Hot Hand Fallacy: Robust Evidence That Belief in the Hot Hand Is Justified.” OSF Preprints. November 1. doi:10.31219/osf.io/pj79r
Abstract: The hot hand fallacy has long been considered a massive and widespread cognitive illusion with important implications in economics and finance. We develop a novel empirical strategy to correct for limitations in the canonical study and replications, conduct an improved field experiment to test for the hot hand in its original domain (basketball shooting), and gather all extant controlled shooting data. In contrast with the previous results, we find strong evidence of hot hand shooting in every dataset, and that expert observers can predict which shooters have a tendency to become hot

Locked-in individuals do not experience the anguish and turmoil that this horrifying situation would lead observers to expect
Phenomenology of the Locked-In Syndrome: an Overview and Some Suggestions. Fernando Vidal. Neuroethics, https://link.springer.com/article/10.1007/s12152-018-9388-1
Abstract: There is no systematic knowledge about how individuals with Locked-in Syndrome (LIS) experience their situation. A phenomenology of LIS, in the sense of a description of subjective experience as lived by the ill persons themselves, does not yet exist as an organized endeavor. The present article takes a step in that direction by reviewing various materials and making some suggestions. First-person narratives provide the most important sources, but very few have been discussed. LIS barely appears in bioethics and neuroethics. Research on Quality of Life (QOL) provides relevant information, one questionnaire study explores the sense of personal continuity in LIS patients, and LIS has been used as a test case of theories in “embodied cognition” and to explore issues in the phenomenology of illness and communication. A systematic phenomenology of LIS would draw on these different areas: while some deal directly with subjective experience, others throw light on its psychological, sociocultural and materials conditions. Such an undertaking can contribute to the improvement of care and QOL, and help inform philosophical questions, such as those concerning the properties that define persons, the conditions of their identity and continuity, or the dynamics of embodiment and intersubjectivity.

Abstract: People often express political opinions in starkly dichotomous terms, such as “Trump will either trigger a ruinous trade war or save U.S. factory workers from disaster.” This mode of communication promotes polarization into ideological in-groups and out-groups. We explore the power of an emerging methodology, forecasting tournaments, to encourage clashing factions to do something odd: to translate their beliefs into nuanced probability judgments and track accuracy over time and questions. In theory, tournaments advance the goals of “deliberative democracy” by incentivizing people to be flexible belief updaters whose views converge in response to facts, thus depolarizing unnecessarily polarized debates. We examine the hypothesis that, in the process of thinking critically about their beliefs, tournament participants become more moderate in their own political attitudes and those they attribute to the other side. We view tournaments as belonging to a broader class of psychological inductions that increase epistemic humility and that include asking people to explore alternative perspectives, probing the depth of their cause-effect understanding and holding them accountable to audiences with difficult-to-guess views.

There was no evidence for a positive association between partner similarity & the three well-being measures; they discuss the implications of this finding for our understanding of partner choice & divorce
Verbakel, Ellen, and Christiaan W. S. Monden. 2018. “Higher Well-being with Similar Partner? Testing the Similarity Hypothesis for Socio-demographic Characteristics.” SocArXiv. July 5. doi:10.31235/osf.io/ahwn6
Abstract: Studies on marriage and divorce often assume, explicitly or implicitly, that there is a positive relationship between partner similarity and well-being. We test this similarity hypothesis: do individuals who share more socio-demographic characteristics with their partners report higher well-being than individuals whose partners are less similar? We analyzed information on more than 2,300 married and cohabiting couples aged 18-50 from the UK Understanding Society wave 1 survey. Three dimensions of well-being were assessed: relationship quality, life satisfaction and psychological distress. We examined similarity on seven characteristics separately and as an index of similarity: age, father’s class, education, ethnicity, religiosity, native language, and parental divorce. The results provided no support for the similarity hypothesis: there was no evidence for a positive association between partner similarity and the three well-being measures. We discuss the implications of this finding for our understanding of partner choice and divorce.

Future clarity—the extent to which the future seems vivid and certain—is associated with the inclination to consume healthy food, abstain from cigarettes, participate in physical activity, & experience positive emotions
Look into the crystal ball: Can vivid images of the future enhance physical health? Simon A Moss et al. Journal of Health Psychology, https://doi.org/10.1177/1359105316669582
Abstract: Many impulsive behaviors, unpleasant emotions, and misguided cognitions increase the incidence of type 2 diabetes and other conditions. This study tests the premise that such risk factors are inversely related to future clarity—the extent to which the future seems vivid and certain. Specifically, 211 participants completed the measures of future clarity and various determinants of health. Future clarity was positively associated with the inclination of participants to consume healthy food, abstain from cigarettes, participate in physical activity, and experience positive emotions. Future research should examine whether interventions designed to help individuals clarify and pursue their aspirations could stem lifestyle diseases.

People infuse their passwords with autobiographical information; some people do it as mementos to cue autobiographical information
People infuse their passwords with autobiographical information. Robbie J. Taylor & Maryanne Garry. Memory, https://doi.org/10.1080/09658211.2018.1539499
ABSTRACT: Passwords might unlock more than our computer accounts. A New York Times Magazine described anecdotes of people who infused their passwords with autobiographical information [Urbina, I. (2014, November 20). The Secret Life of Passwords. New York Times. Retrieved from https://www.nytimes.com/2014/11/19/magazine/the-secret-life-of-passwords.html]. We suspected people infused their passwords with autobiographical information so they could privately remember that information. Across two studies we took a systematic approach to address the extent to which people infused passwords with autobiographical information and the functions that information served. We also examined the self-reported consequences of people infusing their passwords with autobiographical information. Across both studies, 41.6–71.1% of people infused their passwords with autobiographical memories; in Study 2, 9.3% of people infused their passwords with episodic future thoughts. People who infused their password with autobiographical information reported that information served identity, social, and directive functions, and they created their password to remember that information. These studies show that people do not simply use passwords to unlock their computer accounts. Some people might use passwords as mementos to cue autobiographical information.

We perceive good luck itself, rather than material goods, as a limited resource; there is a limited amount of good luck to get, and if another is lucky, he is robbing us
Marciano, Deborah, Eden Krispin, Sacha Bourgeois-Gironde, and Leon Deouell. 2018. “Limited Resources or Limited Luck? Why People Perceive an Illusory Negative Correlation Between the Outcomes of Choice Options Despite Unequivocal Evidence for Independence.” PsyArXiv. October 30. doi:10.31234/osf.io/6rkwd
Abstract: When humans learn of the outcome of an option they did not choose (the alternative outcome), before their own outcome is known, they form biased expectations about their future reward. Specifically, people see an illusory negative correlation between the two outcomes, which we coined the Alternative Omen Effect (ALOE). Why does this happen? Here, we tested several alternative explanations and conclude that the ALOE may derive from a pervasive belief that good luck is a limited resource. In Experiment 1, we show that the ALOE is due to people seeing a good alternative outcome as a bad sign regarding their outcome, but not vice versa. Experiment 2 confirms that the ALOE is a highly ingrained bias that replicates across tasks, and that the ALOE cannot be explained by preconceptions regarding outcome distribution, including 1) the Limited Good Hypothesis (zero-sum bias), according to which people see the world as a zero-sum game, and assume that resources there means fewer resources here, and/or 2) a more specific assumption that laboratory tasks are programmed as zero-sum games. To neutralize these potential beliefs, participants had to draw actual colored beads from two real, distinct bags. In spite of the unequivocal situational evidence of the independence of the two resources, we found a strong ALOE. Finally, in Experiment 3, we tested the Limited Luck Hypothesis: by eliminating the value of the outcomes we eliminated the ALOE. These results suggest that individuals perceive good luck itself, rather than material goods, as a limited resource. We discuss how the Limited Luck belief might explain a wide range of behaviors traditionally associated with the Limited Good belief.

Brain connectivity is associated with personality traits (Five-factor model of personality), forming a “global personality network”; that network is more similar between monozygotic twin pairs compared to the dizygotic twin pairs
Intersubject similarity of personality is associated with intersubject similarity of brain connectivity patterns. Wei Liu, Nils Kohn, Guillén Fernández. NeuroImage, https://doi.org/10.1016/j.neuroimage.2018.10.062
Highlights
• Brain connectivity is associated with personality traits (Five-factor model of personality), forming a “global personality network”.
• Global personality network is more similar between monozygotic twin pairs compared to the dizygotic twin pairs.
• Intersubject network similarity analysis can identify pairs of participants with similar personality profiles.
• Global personality network can predict participants’ item-level responses in the Five-Factor Model.
Abstract: Personality is a central high-level psychological concept that defines individual human beings and has been associated with a variety of real-world outcomes (e.g., mental health and academic performance). Using 2 h, high resolution, functional magnetic resonance imaging (fMRI) resting state data of 984 (primary dataset N = 801, hold-out dataset N = 183) participants from the Human Connectome Project (HCP), we investigated the relationship between personality (five-factor model, FFM) and intrinsic whole-brain functional connectome. We found a pattern of functional brain connectivity (“global personality network”) related to personality traits. Consistent with the heritability of personality traits, the connectivity strength of this global personality network is also heritable (more similar between monozygotic twin pairs compared to the dizygotic twin pairs). Validated by both the repeated family-based 10-fold cross-validation and hold-out dataset, our intersubject network similarity analysis allowed us to identify participants' pairs with similar personality profiles. Across all the identified pairs of participants, we found a positive correlation between the network similarity and personality similarity, supporting our “similar brain, similar personality” hypothesis. Furthermore, the global personality network can be used to predict the individual subject's responses in the personality questionnaire on an item level. In sum, based on individual brain connectivity pattern, we could predict different facets of personality, and this prediction is not based on localized regions, but rather relies on the individual connectivity pattern in large-scale brain networks.

Abstract: While a growing literature within the study of subjective well-being demonstrates the impact of socio-political factors on subjective well-being, scholars have conspicuously failed to consider the role of the size and scope of government as determinants of well-being. In this study, we examine the size of the public sector as a determinant of cross-national variation in life satisfaction across the industrial democracies. At the individual-level, we find that public employees are happier and exhibit greater life satisfaction than otherwise similar others. At the aggregate level, the data strongly suggest that the subjective well-being varies positively with the size of the public sector. The implications for the study of life satisfaction are discussed.

Men who engage in swinging have higher self-esteem, but women who engage in swinging have self-esteem comparable to others
Swinging high or low? Measuring self-esteem in swingers. Amanda S. Ruzansky, Marissa A. Harrison. The Social Science Journal, https://doi.org/10.1016/j.soscij.2018.10.006
Highlights
• We quantitatively measured the self-esteem of swingers.
• Our sample consisted of 41 participants (19 men and 22 women) identifying as swingers and attending a swinging event.
• Our participants largely matched the demographics reported in other studies of swingers.
• We found that female swingers had self-esteem comparable to a general sample.
Abstract: This study sought to examine the self-esteem of individuals involved in a consensually non-monogamous relationship, the swinging lifestyle. Utilizing the Rosenberg Self-Esteem Scale, the self-esteem of swingers was quantified and compared to a general sample. The results reveal that swingers have higher self-esteem. However, gender differences emerged in post hoc analyses whereby men who engage in swinging have higher self-esteem, but women who engage in swinging have self-esteem comparable to others. Results are discussed in terms of evolutionary and clinical importance. Limitations and future directions are also discussed.

Left-wing electoral victories cause significant and substantial short-term decreases in stock market valuations & in the US dollar value of the domestic currency, while the response of sovereign bond markets is muted
Girardi, Daniele, "Political Shocks and Financial Markets: Regression-Discontinuity Evidence from National Elections" (2018). UMASS Amherst Economics Working Papers. 245. https://scholarworks.umass.edu/econ_workingpaper/245
Abstract: Despite growing interest in the effect of political-institutional factors on the economy, causally identified evidence on the reaction of financial markets to electoral outcomes is still relatively scarce, due to the difficulty of isolating causal effects. This paper fills this gap: we estimate the ‘local average treatment effect’ of left-wing (as opposed to conservative) electoral victories on share prices, exchange rates, and sovereign bond yields and spreads. Using a new dataset of worldwide national (parliamentary and presidential) elections in the post-WWII period, we obtain a sample of 954 elections in which main parties/candidates can be classified on the left-right scale based on existing sources and monthly financial data are available. To achieve causal identification, we employ a dynamic regression-discontinuity design, thus focusing on close elections. We find that left-wing electoral victories cause significant and substantial short-term decreases in stock market valuations and in the US dollar value of the domestic currency, while the response of sovereign bond markets is muted. Effects at longer time horizons (6 to 12 months) are very dispersed, signaling large heterogeneity in medium-run outcomes. Stock market and exchange rate effects are stronger and more persistent in elections in which the Left’s proposed economic policy is more radical, in developing economies, and in the post-1990 period.

Holding People Responsible for Ethical Violations: The Surprising Benefits of Accusing Others
Building trust by tearing others down: When accusing others of unethical behavior engenders trust. Jessica A. Kennedy, Maurice E. Schweitzer. Organizational Behavior and Human Decision Processes, Volume 149, November 2018, https://doi.org/10.1016/j.obhdp.2018.10.001
Highlights
• Accusing others of unethical behavior can engender greater trust in an accuser.
• Accusations can elevate trust by boosting perceptions of accusers’ integrity.
• Accusations fail to build trust when they are perceived to reflect ulterior motives.
• Morally hypocritical accusers and false accusations fail to build trust.
• Accusations harm trust in the target.
Abstract: We demonstrate that accusations harm trust in targets, but boost trust in the accuser when the accusation signals that the accuser has high integrity. Compared to individuals who did not accuse targets of engaging in unethical behavior, accusers engendered greater trust when observers perceived the accusation to be motivated by a desire to defend moral norms, rather than by a desire to advance ulterior motives. We also found that the accuser’s moral hypocrisy, the accusation's revealed veracity, and the target’s intentions when committing the unethical act moderate the trust benefits conferred to accusers. Taken together, we find that accusations have important interpersonal consequences.

Abstract: Individuals who accuse others of unethical behavior can derive significant benefits. Compared to individuals who do not make accusations, accusers engender greater trust and are perceived to have higher ethical standards. In Study 1, accusations increased trust in the accuser and lowered trust in the target. In Study 2, we find that accusations elevate trust in the accuser by boosting perceptions of the accuser’s ethical standards. In Study 3, we find that accusations boosted both attitudinal and behavioral trust in the accuser, decreased trust in the target, and promoted relationship conflict within the group. In Study 4, we examine the moderating role of moral hypocrisy. Compared to individuals who did not make an accusation, individuals who made an accusation were trusted more if they had acted ethically but not if they had acted unethically. Taken together, we find that accusations have significant interpersonal consequences. In addition to harming accused targets, accusations can substantially benefit accusers.

Adoption as A Strategy to Fulfill Sex Preferences of U.S. Parents: Children were more likely to be of the missing sex (i.e., girls were more likely than were boys to have only preceding brothers)
Adoption: A Strategy to Fulfill Sex Preferences of U.S. Parents. Ashley Larsen Gibby, Kevin J. A. Thomas. Journal of Marriage and Family,
https://doi.org/10.1111/jomf.12541
Abstract
Objective: This article examines adoption as a strategy used by parents in the United States to fulfill their preference for a specific sex composition among their children.
Background: Evidence from the United States suggests that parents with children of the same sex are more likely to continue childbearing, as parents generally desire at least one girl and one boy. What is unknown, however, is whether parents use adoption to fulfill this same preference.
Method: Using data from the 2016 American Community Survey (n = 1,107,800 children), the authors test the relationships among the sex composition of preceding siblings, child sex, and adoption status.
Results: Children who had same‐sex preceding siblings were more likely to be adopted, as opposed to biologically related to their parents, than children who had mixed‐sex preceding siblings. Furthermore, adopted children were more likely to be of the missing sex (i.e., adopted girls were more likely than were adopted boys to have only preceding brothers).
Conclusion: These findings suggest a need to consider parental sex preferences and child sex in studies on adoption decisions. Furthermore, the results point to adoption as an additional mechanism parents can use to achieve a balanced sex composition among their children.

How The High Priests Of Science Lost Their Status & Prestige
How The High Priests Of Science Lost Their Status & Prestige
John Horgan, The Wall Street Journal, October 19 2018
Stephen Hawking and Martin Rees recognize science’s declining status. But both authors fail to mention that science’s wounds are at least partially self-inflicted. I’m glad I witnessed science’s high priests at the height of their glory. But perhaps we are better off doubting all authorities, including scientific ones.
A high point of my career as a science journalist was a cosmology workshop I bulled my way into in 1990. Thirty luminaries of physics gathered in a rustic resort in northern Sweden to swap ideas about how our universe was born. Stephen Hawking, although almost entirely paralyzed, was the id of the meeting, a joker with a Mick Jagger smirk. Martin Rees, cool and elegant, was the superego, as was befitting for a future president of the Royal Society, one of science’s most venerable institutions.
Personalities aside, Hawking and Mr. Rees had much in common. Born in 1942, both became professors at the University of Cambridge, where Newton once taught. Both contributed to our modern understanding of the big bang, black holes, galaxies and other cosmic matters. Both were committed to telling the public about science’s astonishing revelations.
One afternoon everyone piled into a bus and drove to a local church to hear a concert. As the scientists proceeded down the center aisle of the packed church, led by Hawking in his wheelchair, parishioners stood and applauded. These churchgoers seemed to be acknowledging that science was displacing religion as the source of answers to the deepest mysteries, like why we exist.
That scene came to mind as I read two new books, “Brief Answers to the Big Questions,” by Hawking and “On the Future: Prospects for Humanity” by Mr. Rees. The authors’ styles differ—Hawking cocky, Mr. Rees sober—but the substance of their books overlaps. They offer brisk, lucid peeks into the future of science and of humanity. They evince a profound faith in science’s power to demystify nature and bend it to our ends.
Yet reading these books was a bittersweet experience, and not only because Hawking died last March, at 76. (His book was completed by colleagues and family members.) The works resemble relics from a long-gone golden age: The high priests of science no longer enjoy the prestige they did just a few decades ago.
Hawking in this book is less brash than he once was. In 1980 he proclaimed that, by the end of the 20th century, physicists would discover an “ultimate theory” that would solve the riddle of existence. It would tell us what reality is made of, where it came from and why it takes the form that it does. In “Brief Answers” Hawking concedes that “we are not there yet,” and he pushes back his prediction for a “theory of everything” to the end of thiscentury. But he continues to promote the same ideas that he has for decades. String theory remains his favorite “theory of everything.” Also called M-theory, it conjectures that reality is made of infinitesimal strings, loops or membranes wriggling in a hyperspace of 10 dimensions.
Noting that, according to quantum mechanics, empty space seethes with particles popping into and out of existence, Hawking suggests that the entire universe began as one of these virtual particles. The universe is “the ultimate free lunch,” he says. Our universe may also be just one of many. M-theory, quantum mechanics and inflation—a theory of cosmic creation—all suggest our cosmos is just a minuscule bubble in an infinite ocean, or “multiverse.”
To explain why we live in this universe rather than one with radically different laws, Hawking invokes the “anthropic principle”: If our universe were not as we observe it to be, we would not be here to observe it. Our scientific picture of the cosmos, Hawking proposes, is already so complete that it eliminates the need for God. “No one created the universe,” he declares, “and no one directs our fate.”
Science can save us, too, Hawking states. It gives us the means to establish colonies on Mars and elsewhere in case the Earth becomes unlivable—whether because of nuclear war, runaway warming, pandemics or an asteroid collision. “If humanity is to continue for another million years,” he states, “our future lies in boldly going where no one else has gone before.”
Mr. Rees’s worldview differs in a few respects from Hawking’s. He describes himself as a “practising but unbelieving Christian.” He respects believers, with whom he shares “a sense of wonder and mystery.” As for space-colonization, Mr. Rees asserts that it is “a dangerous delusion to think that space offers an escape from Earth’s problems.” He dwells more than Hawking on threats posed by climate change, nuclear weapons, bioterrorism, asteroid collisions and even economic inequality. He urges redistribution of the “enormous wealth” generated by the “digital revolution.”
Yet the Cambridge colleagues agree on major issues. That machines will inevitably become super-intelligent, capable of learning without human guidance and pursuing their own goals. That we can nonetheless harness these machines for our own ends, or even merge with them. That we need more science and technology to help us overcome challenges to our peace and prosperity. That science will eventually explain the origin of this universe and even confirm the existence of other universes.
“It’s highly speculative,” Mr. Rees says of multiverse theory. “But it’s exciting science. And it may be true.” Mr. Rees also shares Hawking’s vision of “post-human” cyborgs fanning out through the universe to colonize other star systems. Our bionic descendants might be smart enough to invent warp-drive spaceships and time machines, Mr. Rees suggests. They might even solve what many scientists and philosophers consider the greatest mystery of all, the mind-body problem. This puzzle asks, as Mr. Rees puts it, “how atoms can assemble into ‘grey matter’ that can become aware of itself and ponder its origins.”
Hawking and Mr. Rees recognize science’s declining status. They call for better science education to lure more young people into science and to counter public ignorance about vaccines, genetically modified foods, climate change, nuclear power, and evolution. “The low esteem in which science and scientists are held is having serious consequences,” Hawking complains.
Both authors fail to mention that science’s wounds are at least partially self-inflicted. In 2005 statistician John Ioannidis presented evidence that “most published research findings are wrong.” That is, the findings cannot be replicated by follow-up research. Many other scholars have now confirmed the work of Mr. Ioannidis. The so-called replication crisis is especially severe in fields with high financial stakes, such as oncology and psychopharmacology.
But physics, which should serve as the bedrock of science, is in some respects the most troubled field of all. Over the last few decades, physics in the grand mode practiced by Hawking and Mr. Rees has become increasingly disconnected from empirical evidence. Proponents of string and multiverse models tout their mathematical elegance, but strings are too small and multiverses too distant to be detected by any conceivable experiment.
In her new book “Lost in Math,” German physicist Sabine Hossenfelder offers a far more candid and compelling assessment of modern physics than her English elders. She fears that physicists working on strings and multiverses are not really practicing physics. “I’m not sure anymore that what we do here, in the foundations of physics, is science,” she confesses.
As I finished “Brief Answers to the Big Questions” and “On the Future,” a few questions of my own came to mind. Will science regain its luster? Will it earn back the public’s trust, or will its authority be permanently diminished? And what outcome should we prefer? I’m glad I witnessed science’s high priests at the height of their glory. But perhaps we are better off doubting all authorities, including scientific ones.
John Horgan, The Wall Street Journal, October 19 2018
Stephen Hawking and Martin Rees recognize science’s declining status. But both authors fail to mention that science’s wounds are at least partially self-inflicted. I’m glad I witnessed science’s high priests at the height of their glory. But perhaps we are better off doubting all authorities, including scientific ones.
A high point of my career as a science journalist was a cosmology workshop I bulled my way into in 1990. Thirty luminaries of physics gathered in a rustic resort in northern Sweden to swap ideas about how our universe was born. Stephen Hawking, although almost entirely paralyzed, was the id of the meeting, a joker with a Mick Jagger smirk. Martin Rees, cool and elegant, was the superego, as was befitting for a future president of the Royal Society, one of science’s most venerable institutions.
Personalities aside, Hawking and Mr. Rees had much in common. Born in 1942, both became professors at the University of Cambridge, where Newton once taught. Both contributed to our modern understanding of the big bang, black holes, galaxies and other cosmic matters. Both were committed to telling the public about science’s astonishing revelations.
One afternoon everyone piled into a bus and drove to a local church to hear a concert. As the scientists proceeded down the center aisle of the packed church, led by Hawking in his wheelchair, parishioners stood and applauded. These churchgoers seemed to be acknowledging that science was displacing religion as the source of answers to the deepest mysteries, like why we exist.
That scene came to mind as I read two new books, “Brief Answers to the Big Questions,” by Hawking and “On the Future: Prospects for Humanity” by Mr. Rees. The authors’ styles differ—Hawking cocky, Mr. Rees sober—but the substance of their books overlaps. They offer brisk, lucid peeks into the future of science and of humanity. They evince a profound faith in science’s power to demystify nature and bend it to our ends.
Yet reading these books was a bittersweet experience, and not only because Hawking died last March, at 76. (His book was completed by colleagues and family members.) The works resemble relics from a long-gone golden age: The high priests of science no longer enjoy the prestige they did just a few decades ago.
Hawking in this book is less brash than he once was. In 1980 he proclaimed that, by the end of the 20th century, physicists would discover an “ultimate theory” that would solve the riddle of existence. It would tell us what reality is made of, where it came from and why it takes the form that it does. In “Brief Answers” Hawking concedes that “we are not there yet,” and he pushes back his prediction for a “theory of everything” to the end of thiscentury. But he continues to promote the same ideas that he has for decades. String theory remains his favorite “theory of everything.” Also called M-theory, it conjectures that reality is made of infinitesimal strings, loops or membranes wriggling in a hyperspace of 10 dimensions.
Noting that, according to quantum mechanics, empty space seethes with particles popping into and out of existence, Hawking suggests that the entire universe began as one of these virtual particles. The universe is “the ultimate free lunch,” he says. Our universe may also be just one of many. M-theory, quantum mechanics and inflation—a theory of cosmic creation—all suggest our cosmos is just a minuscule bubble in an infinite ocean, or “multiverse.”
To explain why we live in this universe rather than one with radically different laws, Hawking invokes the “anthropic principle”: If our universe were not as we observe it to be, we would not be here to observe it. Our scientific picture of the cosmos, Hawking proposes, is already so complete that it eliminates the need for God. “No one created the universe,” he declares, “and no one directs our fate.”
Science can save us, too, Hawking states. It gives us the means to establish colonies on Mars and elsewhere in case the Earth becomes unlivable—whether because of nuclear war, runaway warming, pandemics or an asteroid collision. “If humanity is to continue for another million years,” he states, “our future lies in boldly going where no one else has gone before.”

Pornography consumption was associated with an impersonal approach to sex among both men and women; among both adolescents and adults; and across countries, time, and methods
Pornography and Impersonal Sex. Robert S Tokunaga, Paul J Wright, Joseph E Roskos. Human Communication Research, hqy014, https://doi.org/10.1093/hcr/hqy014
Abstract: This paper presents meta-analytic findings on pornography consumption and impersonal sexual attitudes and behaviors. Results were based on more than 70 reports spanning over 40 years of research. Data from 13 countries were located, with attitudinal results from more than 45,000 participants and behavioral results from over 60,000 participants. Pornography consumption was associated with an impersonal approach to sex among both men and women; among both adolescents and adults; and across countries, time, and methods. Mediation results were consistent with the sexual script theory hypothesis that viewing pornography leads to more impersonal sexual attitudes, which in turn increase the likelihood of engaging in impersonal sexual behavior. Confounding analysis did not support the libertarian theory of pornography's hypothesis that the only reason why pornography consumption correlates with impersonal sexual behavior is because people who are already impersonal in their approach to sex are more likely to consume pornography and engage in impersonal sexual acts.

30 Pacific and Indian Ocean atolls including 709 islands: No atoll lost land area, 88.6% of islands were either stable or increased in area, while only 11.4% contracted; atolls affected by rapid sea‐level rise did not show a distinct behavior
A global assessment of atoll island planform changes over the past decades. Virginie K. E. Duvat. Wiley Interdisciplinary Reviews: Climate Change. https://doi.org/10.1002/wcc.557
Abstract: Over the past decades, atoll islands exhibited no widespread sign of physical destabilization in the face of sea‐level rise. A reanalysis of available data, which cover 30 Pacific and Indian Ocean atolls including 709 islands, reveals that no atoll lost land area and that 88.6% of islands were either stable or increased in area, while only 11.4% contracted. Atoll islands affected by rapid sea‐level rise did not show a distinct behavior compared to islands on other atolls. Island behavior correlated with island size, and no island larger than 10 ha decreased in size. This threshold could be used to define the minimum island size required for human occupancy and to assess atoll countries and territories' vulnerability to climate change. Beyond emphasizing the major role of climate drivers in causing substantial changes in the configuration of islands, this reanalysis of available data indicates that these drivers explain subregional variations in atoll behavior and within‐atoll variations in island and shoreline (lagoon vs. ocean) behavior, following atoll‐specific patterns. Increasing human disturbances, especially land reclamation and human structure construction, operated on atoll‐to‐shoreline spatial scales, explaining marked within‐atoll variations in island and shoreline behavior. Collectively, these findings highlight the heterogeneity of atoll situations. Further research needs include addressing geographical gaps (Indian Ocean, Caribbean, north‐western Pacific atolls), using standardized protocols to allow comparative analyses of island and shoreline behavior across ocean regions, investigating the role of ecological drivers, and promoting interdisciplinary approaches. Such efforts would assist in anticipating potential future changes in the contributions and interactions of key drivers.

This evidence supports my claim that the threat of conventional retaliation is sufficient to deter a preventive strike against emerging nuclear state
Closing the Window of Vulnerability: Nuclear Proliferation and Conventional Retaliation. Jan Ludvik. Security Studies, https://doi.org/10.1080/09636412.2018.1508635
Abstract: Living with a nuclear-armed enemy is unattractive, but, strangely, states seldom use their military power to prevent the enemy’s entry into the nuclear club. It is puzzling why preventive strikes against nuclear programs have been quite rare. I address this puzzle by considering the role of conventional retaliation, a subfield of deterrence that so far has received scant attention in the literature. I theorize the concept of conventional retaliation and test its explanatory power. First, I explore all historical cases where states struck another state’s nuclear installations and find none occurring when the proliferator threatened conventional retaliation. Second, I explore two cases where a strike was most likely, but the would-be attacker balked and find smoking-gun evidence that the threat of conventional retaliation restrained the would-be attacker. This evidence supports my claim that the threat of conventional retaliation is sufficient to deter a preventive strike against emerging nuclear states.

From 2013, Secret Codes of Political Propaganda: The Unknown System of Writing Teams
From 2013, Secret Codes of Political Propaganda: The Unknown System of Writing Teams. Wen-Hsuan Tsai and Peng-Hsiang Kao. The China Quarterly, Volume 214, June 2013, pp. 394-410, https://doi.org/10.1017/S0305741013000362
Abstract: Within the Chinese Communist Party (CCP), some Party units have established a largely unknown network of writing teams which propagate the policies or perspectives of a particular unit by publishing feature articles in Party journals. These writing teams often make use of a pseudonym in the form of a person's name, leading outsiders to believe that the work is written by a journalist. In fact, the pseudonyms of the Party unit writing teams function as a form of secret code. Through this code, inner Party members can recognize which unit's views an article reflects. In order to reveal exactly which units the codes represent, we have collated the names of over 20 writing teams. In addition, we provide an introduction to the functioning of the writing teams and the manner in which articles are produced. Finally, we propose that the CCP's mechanism of “propaganda codes” is gradually undergoing the process of institutionalization.

Brain Tissue–Volume Changes in Cosmonauts: Gray-matter volume decreases, cerebrospinal fluid increases
Brain Tissue–Volume Changes in Cosmonauts. Angelique Van Ombergen et al. N Engl J Med 2018; 379:1678-1680, October 25, 2018, DOI: 10.1056/NEJMc1809011
Long-duration spaceflight has detrimental effects in several physiological systems. Several studies have shown an upward shift of the cerebral hemispheres, a decrease in frontotemporal volume, and an increase in ventricle size after spaceflight.1-3 However, information is limited about the effects of microgravity on brain volume, particularly regarding changes that are evident more than 1 month after spaceflight.
We prospectively studied data from T1-weighted magnetic resonance imaging (MRI) that was performed in 10 male cosmonauts (mean age, 44 years; average space-mission duration, 189 days) at three time points: preflight (in 10 cosmonauts), short-term postflight (average, 9 days postflight; in 10), and long-term postflight follow-up (average, 209 days postflight; in 7). The volumes of gray matter, white matter, and cerebrospinal fluid (CSF) were analyzed with the use of voxel-based morphometry. [...]
The gray-matter volume postflight as compared with preflight showed a widespread decrease in the orbitofrontal and temporal cortexes; the maximal decrease was 3.3% in the right middle temporal gyrus. At long-term postflight follow-up, most reductions in gray-matter volume had recovered toward preflight levels (e.g., a 1.2% reduction in gray-matter volume persisted in the right temporal gyrus). The white-matter volume postflight as compared with preflight was reduced along a longitudinal tract of the left temporal lobe, but there was a global reduction of cerebral white-matter volume at long-term follow-up as compared with postflight. The ventral CSF spaces of the cerebral hemispheres and the ventricles had increased in volume postflight as compared with preflight (maximal increase, 12.9% in the third ventricle), while CSF volume below the vertex decreased. At long-term follow-up, the CSF volume in the ventricles had returned toward preflight values, while the CSF volume in the entire subarachnoid space around the brain had increased. Changes in the volumes of gray matter and CSF are shown in Figure 1.

Attributes associated with sexual attractiveness in female bodies (waist-to-hip ratio) are processed rapidly in the stream of visual processing
Waist‐to‐hip ratio affects female body attractiveness and modulates early brain responses. Marzia Del Zotto, David Framorando, Alan J. Pegna. European Journal of Neuroscience, https://doi.org/10.1111/ejn.14209
Abstract: This investigation examined the electrophysiological response underlying the visual processing of waist‐to‐hip ratio (WHR) in female bodies, a characteristic known to affect perceived attractiveness. WHRs of female bodies were artificially adjusted to values of 0.6, 0.7, 0.8 or 0.9. Behavioural ratings of attractiveness of the bodies revealed a preference for WHRs of 0.7 in the overall group of participants, which included both male and female heterosexual individuals. Event‐related potentials (ERPs) were then recorded while participants performed a selective attention task involving photographs of female models and scrambled images. Results showed that the P1 (80‐120 ms) and N1 (130‐170 ms) components situated over posterior brain regions were the earliest components to be modulated by attention and bodies. Interestingly, the VPP, a vertex‐positive potential occurring between 120‐180 ms, produced a greater positivity for WHRs of 0.7 compared to the other ratios. However, this increase was only observed when the body stimuli were attended, while no effect was observed for unattended bodies. These findings provide evidence of an early brain sensitivity to visual attributes that constitute secondary sexual characteristics. Although they are relatively discrete from the point of view of their physical quality, these signs possess strong behavioural significance, producing greater reported attractiveness, likely by conveying the biological meaning that signals good health and greater reproductive success. Our results therefore reveal that attributes associated with sexual attractiveness in female bodies are processed rapidly in the stream of visual processing.

Those paired with an opposite-sex partner exerciced a higher levels of intensity and traveled greater distances during their workouts; and even more if single

When people are aware that potential mates are observing their performances, they may alter their behavior (consciously or unconsciously) in order to make themselves appear more desirable to these individuals. This is consistent with previous research showing that matingrelated display strategies may be situationally sensitive, such that people will only engage in these displays when they believe that their performance will be viewed by a desirable functionally-relevant target (Baker & Maner, 2008, 2009).
In general, the current research demonstrates the utility of applying an evolutionary perspective to generate and test specific predictions regarding how human performance varies depending upon both fundamental social motives and social context. A more general social psychological theory such as social facilitation theory would generate a prediction that performance would be similarly enhanced in the presence of any partner, regardless of individual differences in relationship status or mating motives. However, our results demonstrate that performance in the presence of another individual varies depending on the sex of the individuals in the situation as well as the motives of the actor. We argue that this finding is best interpreted as being a product of human mating strategies. More specifically, the pattern of observed results is consistent with predictions generated by costly signaling theory and the fundamental social motives perspective. Improvements in performance were observed only in the presence of a potential mate and only when the actor possessed personal characteristics associated with greater levels of motivation to seek a mate. Accounting for individual differences in fundamental social motives and functionally relevant social factors can lead to the generation of novel hypotheses about how these factors interact to impact performance. Although the current research focused on exercise performance, it is reasonable to speculate that fundamental social motives and social context might interact to influence performance of a range of different behaviors in functionally relevant ways.
The findings of the current work demonstrate how social context can affect performance in a manner consistent with a sexual display strategy. By tailoring one’s behaviors to the preferences of potential mates, these behaviors can serve as advertisements of desirable qualities, allowing people to market themselves as desirable romantic or sexual prospects. In order to better understand why people behave the way that they do in any given situation, it is helpful to take into account the opportunities afforded by the social context as well as the fundamental social goals that the actor is motivated to pursue. This work demonstrates that conceptualizing public behaviors as serving a social display function can lead to an improved understanding of the impact of social context on performance.

Endogenous Emotion Generation Abilities Support Adaptive Emotion Regulation & More Happiness
Engen, Haakon, Philipp Kanske, and Tania Singer. 2018. “Endogenous Emotion Generation Abilities Support Adaptive Emotion Management.” PsyArXiv. October 28. doi:10.31234/osf.io/4yxkv
Abstract: Emotions are frequently thought of as reactions to events in the world. However, many of our emotional experiences are of our own making, coming from thoughts and memories. These different origins mean that these endogenous emotions are more controllable than exogenous emotions, making plausible a role of endogenous emotion in self-regulation and mental health. We tested this idea in a representative sample of 277 individuals (163 female, 20-55 years) who partook in an experiment measuring individual differences in endogenous emotion generation ability and a questionnaire battery measuring individual differences in trait affect and emotional self-regulation style. Two hypotheses for how endogenous emotion generation can facilitate mental health were tested: By buffering negative stressors with self-generated positive emotion enabling use of emotion-focused regulation techniques, or by allowing effective simulation of the emotional consequences of future events, facilitating active and instrumental coping. Support for both hypotheses was found. Consistent with buffering, positive emotion generation ability mediated the relationship between emotion-focused regulation and trait affect, while the ability to generate emotions regardless of valence, was found to mediate the relationship between active and instrumental regulation and trait affect, supporting a simulation account. This suggests role of emotion generation in emotion regulation, a finding of both theoretical and practical implication for mental health interventions.
Abstract: Emotions are frequently thought of as reactions to events in the world. However, many of our emotional experiences are of our own making, coming from thoughts and memories. These different origins mean that these endogenous emotions are more controllable than exogenous emotions, making plausible a role of endogenous emotion in self-regulation and mental health. We tested this idea in a representative sample of 277 individuals (163 female, 20-55 years) who partook in an experiment measuring individual differences in endogenous emotion generation ability and a questionnaire battery measuring individual differences in trait affect and emotional self-regulation style. Two hypotheses for how endogenous emotion generation can facilitate mental health were tested: By buffering negative stressors with self-generated positive emotion enabling use of emotion-focused regulation techniques, or by allowing effective simulation of the emotional consequences of future events, facilitating active and instrumental coping.

Imprisonments in hospitals in at least 30 other countries, including Nigeria and the Democratic Republic of the Congo, China & Thailand, Lithuania & Bulgaria, & others in Latin America & the Middle East
AP Investigation: Hospital patients held hostage for cash. MARIA CHENG. AP, October 25, 2018. https://apnews.com/daf47512c8f74e869b722782299b4a0e
NAIROBI, Kenya (AP) — The Kenyatta National Hospital is east Africa’s biggest medical institution, home to more than a dozen donor-funded projects with international partners — a “Center of Excellence,” says the U.S. Centers for Disease Control and Prevention.
The hospital’s website proudly proclaims its motto — “We Listen ... We Care” — along with photos of smiling doctors, a vaccination campaign and staffers holding aloft a gold trophy at an awards ceremony.
But there are no pictures of Robert Wanyonyi, shot and paralyzed in a robbery more than a year ago. Kenyatta will not allow him to leave the hospital because he cannot pay his bill of nearly 4 million Kenyan shillings ($39,570). He is trapped in his fourth-floor bed, unable to go to India, where he believes doctors might help him.
At Kenyatta National Hospital and at an astonishing number of other hospitals around the world, if you don’t pay up, you don’t go home.
The hospitals often illegally detain patients long after they should be medically discharged, using armed guards, locked doors and even chains to hold those who have not settled their accounts. Mothers and babies are sometimes separated. Even death does not guarantee release: Kenyan hospitals and morgues are holding hundreds of bodies until families can pay their loved ones’ bills, government officials say.
Dozens of doctors, nurses, health experts, patients and administrators told The Associated Press of imprisonments in hospitals in at least 30 other countries, including Nigeria and the Democratic Republic of the Congo, China and Thailand, Lithuania and Bulgaria, and others in Latin America and the Middle East.
The AP investigation built on a report last year by the British think-tank Chatham House; its experts found more than 60 press reports of patient detention in 14 countries in Asia and sub-Saharan Africa.
“What’s striking about this issue is that the more we look for this, the more we find it,” said Dr. Ashish Jha, director of the Harvard Global Health Institute, who was not involved in the British research. “It’s probably hundreds of thousands if not millions of people that this affects worldwide. It is not something that is only happening in a small number of countries, but the problem is that nobody is looking at this and it is way off the public health radar.”
Some examples:
—In the Philippines, Annalyn Manalo was held at Mount Carmel Diocesan General Hospital in Lucena City for 1½ months starting last December following treatment for heart problems. Administrators refused initially to allow her family to pay in installments — and the cost of each extra day in detention was added to the bill.
“We were treated like criminals,” said Manalo’s husband, Sigfredo. “The security guards would come and check on us all the time.”
—In Congo’s second city of Lubumbashi, the AP visited more than 20 hospitals and clinics and found that all but one routinely detained patients who failed to pay, even though the practice is illegal there.
—In Bangalore, India, Emmanuel Malagi was detained in a private hospital for three months after he was treated for a spinal tumor, according to his brother, Christanand. Prevented from seeing him, his family scrambled unsuccessfully to pay his nearly 1.4 lakh rupees ($19,281) bill — and when he died, the hospital demanded another 10 lakh ($13,771) to release the body.
—In Malaysia, a medical student from the Netherlands on a diving trip got the bends. He couldn’t afford his decompression treatment; the hospital locked him in a room for four days, with no food or drink, until he was able to get the money, according to Saskia Mostert, a Dutch academic who has researched hospital detentions.
—In Bolivia, a government ombudsman reported that 49 patients were detained in hospitals or clinics in the last two years because they couldn’t pay, despite a law that prohibits the practice.
During several August visits to Kenyatta National Hospital, The Associated Press witnessed armed guards in military fatigues standing watch over patients, and saw where detainees slept on bedsheets on the floor in cordoned-off rooms. Guards prevented one worried father from seeing his detained toddler. All despite a court ruling years ago that found the detentions were illegal.
Health experts decry hospital imprisonment as a human rights violation. Yet the United Nations, U.S. and international health agencies, donors and charities all have remained silent while pumping billions of dollars into these countries to support splintered health systems or to fight outbreaks of diseases including AIDS and malaria.
“It’s the dirty underbelly of global health that nobody wants to talk about,” said Sophie Harman, a health academic at Queen Mary University of London.
“People know patients are being held prisoner, but they probably think they have bigger battles in public health to fight, so they just have to let this go.”
[...]
Where patients are imprisoned, hospitals acknowledge it is not necessarily profitable. But many say it often leads at least to partial payment and serves as a deterrent.
Unlike many hospitals in developed countries, African hospitals don’t always provide food, clothing or bedding for patients, so holding onto them does not necessarily incur a significant cost. Detained patients typically rely on relatives to bring them food while those without obliging family members resort to begging for help from staff or other patients.
Dr. Festus Njuguna, a pediatric oncologist at the Moi Teaching and Referral Hospital in Eldoret, about 300 kilometers northwest of Nairobi, said the institution regularly holds children with cancer who have finished their treatment, but whose parents cannot pay. The children are typically left on the wards for weeks and months at a time, long after their treatment has ended.
“It’s not a very good feeling for the doctors and nurses who have treated these patients, to see them kept like this,” Njuguna said.
Still, some officials openly defend the practice.
“We can’t just let people leave if they don’t pay,” said Leedy Nyembo-Mugalu administrator of Congo’s Katuba Reference Hospital. He said holding patients wasn’t an issue of human rights, but simply a way to conduct business: “No one ever comes back to pay their bill a month or two later.”
At many Kenyan hospitals, including Kenyatta, officials armed with rifles patrol the hallways and guard the hospital’s gates. Patients must show hospital guards a discharge form to prove they’re allowed to leave and even visitors must sometimes surrender their identification cards before seeing patients.
[...]
“This is something that hospital authorities have been trying to keep under wraps,” said George Morara, vice chairperson of the country’s national commission on human rights. He said the number of Kenyans imprisoned in hospitals is “disturbingly high” and that the practice is “ubiquitous in public and private hospitals.”
He said patients have been held at Kenyatta for up to two years, and it was reasonable to suspect that hundreds of patients could be detained there at any time.
Kenya’s ministry of health and Kenyatta canceled several scheduled interviews with the AP and declined to respond to repeated requests for comment.
[...]
Although the court instructed the government to produce guidelines on how hospitals should waive fees for patients unable to pay, Opondo said the proposed fixes have not gone far enough. A program that provides free maternity care is only available at a select number of private hospitals and does not include post-delivery care.
Earlier this month, Kenya’s High Court ruled again that imprisoning patients “is not one of the acceptable avenues (for hospitals) to recover debt.” The case involved a man detained at Nairobi Women’s Hospital since June 25; the judge ordered his immediate release despite the outstanding bill. Kenyan politicians also will soon debate a proposed amendment to the country’s health law that will explicitly make patient detentions illegal.
The latest amendment was submitted by MP Jared Okelo, a member of Parliament who described the imprisonment of mothers as “rampant.”
Omuya is still scarred by her detention at Pumwani. She says she developed chronic pneumonia after being held in the damp, cold conditions there and has not been able to work full-time since.
Neither Omuya nor Oliele have been paid the damages awarded to them by the court: Omuya was to receive 1,500,000 shillings ($14,842) from the hospital while Oliele was to receive 500,000 shillings ($4,948).

Paraventricular thalamic neurons represent multiple salient features of sensory stimuli, like reward, aversiveness, novelty, & surprise; the nucleus thus provides context-dependent salience encoding
Dynamic salience processing in paraventricular thalamus gates associative learning. Yingjie Zhu, Gregory Nachtrab, Piper C. Keyes, William E. Allen, Liqun Luo, Xiaoke Chen. Science , Vol. 362, Issue 6413, pp. 423-429. DOI: 10.1126/science.aat0481
Abstract: The salience of behaviorally relevant stimuli is dynamic and influenced by internal state and external environment. Monitoring such changes is critical for effective learning and flexible behavior, but the neuronal substrate for tracking the dynamics of stimulus salience is obscure. We found that neurons in the paraventricular thalamus (PVT) are robustly activated by a variety of behaviorally relevant events, including novel (“unfamiliar”) stimuli, reinforcing stimuli and their predicting cues, as well as omission of the expected reward. PVT responses are scaled with stimulus intensity and modulated by changes in homeostatic state or behavioral context. Inhibition of the PVT responses suppresses appetitive or aversive associative learning and reward extinction. Our findings demonstrate that the PVT gates associative learning by providing a dynamic representation of stimulus salience.

A close view of the paraventricular thalamus
The paraventricular thalamus is a relay station connecting brainstem and hypothalamic signals that represent internal states with the limbic forebrain that performs associative functions in emotional contexts. Zhu et al. found that paraventricular thalamic neurons represent multiple salient features of sensory stimuli, including reward, aversiveness, novelty, and surprise. The nucleus thus provides context-dependent salience encoding. The thalamus gates sensory information and contributes to the sleep-wake cycle through its interactions with the cerebral cortex. Ren et al. recorded from neurons in the paraventricular thalamus and observed that both population and single-neuron activity were tightly coupled with wakefulness.

Stereotypes about wealthy people’s personality are accurate albeit somewhat exaggerated; wealthy people can be characterized as stable, flexible, & agentic individuals who are focused more on themselves than on others
Leckelt, Marius, David Richter, Carsten Schröder, Albrecht C. P. Küfner, Markus M. Grabka, and Mitja Back. 2018. “The Rich Are Different: Unraveling the Perceived and Self-reported Personality Profiles of High Net-worth Individuals.” PsyArXiv. October 28. doi:10.1111/bjop.12360
Abstract: Beyond money and possessions, how are the rich different from the general population? Drawing on a unique sample of high net-worth individuals from Germany (≥1 million Euro in financial assets; N = 130), nationally representative data (N = 22,981), and an additional online panel (N = 690), we provide the first direct investigation of the stereotypically-perceived and self-reported personality profiles of high net-worth individuals. Investigating the broad personality traits of the Big Five and the more specific traits of narcissism and locus of control, we find that stereotypes about wealthy people’s personality are accurate albeit somewhat exaggerated and that wealthy people can be characterized as stable, flexible, and agentic individuals who are focused more on themselves than on others.

Researchers at Brown U found that alcohol hijacks a conserved memory pathway in the brain and changes which versions of genes are made, forming the cravings that fuel addiction
Alcohol Activates Scabrous-Notch to Influence Associated Memories. Emily Petruccelli et al. Neuron, October 25, 2018. https://doi.org/10.1016/j.neuron.2018.10.005
Highlights
• Alcohol cue preference requires Scabrous-Notch interaction in mushroom body neurons
• Alcohol activates Notch and Su(H) target gene expression in the adult brain
• Dopamine 2 receptor splicing and targeting by Su(H) are altered by alcohol exposure
• Alcohol cue preference affects mushroom body gene expression and splicing
Summary: Drugs of abuse, like alcohol, modulate gene expression in reward circuits and consequently alter behavior. However, the in vivo cellular mechanisms through which alcohol induces lasting transcriptional changes are unclear. We show that Drosophila Notch/Su(H) signaling and the secreted fibrinogen-related protein Scabrous in mushroom body (MB) memory circuitry are important for the enduring preference of cues associated with alcohol’s rewarding properties. Alcohol exposure affects Notch responsivity in the adult MB and alters Su(H) targeting at the dopamine-2-like receptor ( Dop2R). Alcohol cue training also caused lasting changes to the MB nuclear transcriptome, including changes in the alternative splicing of Dop2R and newly implicated transcripts like Stat92E. Together, our data suggest that alcohol-induced activation of the highly conserved Notch pathway and accompanying transcriptional responses in memory circuitry contribute to addiction. Ultimately, this provides mechanistic insight into the etiology and pathophysiology of alcohol use disorder.

Literature said property crimes have more instrumental motives, require planning, & hence are particularly sensitive to permanent changes in cost & benefits, but violent crime declines in U.S. cities on days in which the local pollen count is unusually high
Chalfin, Aaron and Danagoulian, Shooshan and Deza, Monica, More Sneezing, Less Crime? Seasonal Allergies, Transitory Costs and the Market for Offenses (August 18, 2018). http://dx.doi.org/10.2139/ssrn.3234415
Abstract: The neoclassical economic model of crime envisions crime as a gamble undertaken by a rational individual who is weighing the costs and benefits of offending at the margin. A large literature estimates the sensitivity of crime to policy inputs that shift the cost of offending such as police and prisons. In this paper, we point out that participants in the market for offenses also respond to transitory changes in situational factors and that these are in constant flux. We consider the responsiveness of crime to a pervasive and common health shock which we argue shifts costs and benefits for offenders and victims: seasonal allergies. Leveraging daily variation in city-specific pollen counts, we present novel evidence that violent crime declines in U.S. cities on days in which the local pollen count is unusually high and that these effects are driven by residential violence. While past literature suggests that property crimes have more instrumental motives, require planning, and hence are particularly sensitive to permanent changes in the cost and benefits of crime, we find evidence that violence may be especially sensitive to situational factors.

Despite philosophical & conventional wisdom dating back to the ancients, researchers have only recently begun to uncover evidence that extreme standing on “normal” or “desirable” personality traits might be maladaptive
Extreme Personalities at Work and in Life. Nathan T. Carter, Joshua D. Miller, Thomas A. Widiger. Current Directions in Psychological Science, https://doi.org/10.1177/0963721418793134
Abstract: Contemporary personality taxonomies cast personality traits as ranging from the maladaptive (e.g., low conscientiousness) to adaptive (e.g., high conscientiousness) levels. Despite philosophical and conventional wisdom dating back to the ancients, researchers have only recently begun to uncover evidence that extreme standing on “normal” or “desirable” personality traits might be maladaptive. Here, we present an emerging perspective on why and how extreme standing on “desirable” trait continua translates into maladaptive behavior and undesirable outcomes at work and in life. An overview of the literature on the topic is presented for each trait within the five-factor model. We suggest two reasons for the lack of clarity in the empirical literature: (a) problems with statistical tests resulting from measurement error and (b) lack of breadth in the conceptualization and measurement of personality traits. We suggest that a solution to this problem is to extend trait continua to reflect maladaptive levels at both ends. We close by pointing out that a major implication of this emerging perspective indicates that many more people possess optimal personality-trait levels than previously thought and that future research needs to examine whether the question is consistent with evolutionary and neurophysiological accounts of personality science.

27% of participants have kept a financial secret from their partner; and both marital & life satisfaction were lower for participants who have experienced financial infidelity than in those who have not

Four hundred and fourteen participants answered questions regarding financial habits within the context of the couple relationship.The Big Five Personality Inventory and a Martial and Life Satisfaction Scale were used to determine the incidence and factors associated with financial infidelity. Results indicated that 27% of participants have kept a financial secret from their partner. Furthermore, both marital and life satisfaction were lower for participants who have experienced financial infidelity than in those who have not. Finally, conscientiousness, a factor from the Big Five Personality Inventory, showed a significant difference, suggesting that more organized individuals were less likely to keep financial secrets. Clinical implications are also discussed.

Bacon's ideas are central in the culture of growth; his epistemology derives from his jurisprudence &, hence, reflects common-law culture, which can help explain the coincidence of early political & economic development in England
Toward understanding 17th century English culture: A structural topic model of Francis Bacon's ideas. PeterGrajzl, Peter Murrell. Journal of Comparative Economics, https://doi.org/10.1016/j.jce.2018.10.004
Highlights
• Bacon's ideas are central in the culture of growth of early modern England.
• We study Bacon's thought using machine-learning tools for analysis of text-as-data.
• Bacon communicated strategically and did not emphasize some ideas later viewed as Baconian.
• Bacon's epistemology derives from his jurisprudence and, hence, reflects common-law culture.
• Features and origins of Bacon's ideas help interpret England's early development.
Abstract: We use machine-learning methods to study the features and origins of the ideas of Francis Bacon, a key figure who provided the intellectual roots of a cultural paradigm that spurred modern economic development. Bacon's works are the data in an estimation of a structural topic model, a recently developed methodology for analysis of text corpora. The estimates uncover sixteen topics prominent in Bacon's opus. Two are key elements of the ideas usually associated with Bacon—inductive epistemology and fact-seeking. The utilitarian promise of science and the centralized organization of the scientific quest, embraced by Bacon's followers, were not emphasized by him. Using strategic communication, Bacon facilitated reception of his scientific methodology, targeted influential groups, and finessed powerful opponents. We provide the first quantitative evidence that the genesis of Bacon's epistemology lies in his experience in the common-law. Combining our findings with accepted arguments in the existing literature, we suggest that the effects of common-law culture can help explain the coincidence of early political and economic development in England.
Highlights
• Bacon's ideas are central in the culture of growth of early modern England.
• We study Bacon's thought using machine-learning tools for analysis of text-as-data.
• Bacon communicated strategically and did not emphasize some ideas later viewed as Baconian.
• Bacon's epistemology derives from his jurisprudence and, hence, reflects common-law culture.
• Features and origins of Bacon's ideas help interpret England's early development.
