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.
