Abstract: Men's and women's personalities appear to differ in several respects. Social role theories of development assume gender differences result primarily from perceived gender roles, gender socialization and sociostructural power differentials. As a consequence, social role theorists expect gender differences in personality to be smaller in cultures with more gender egalitarianism. Several large cross-cultural studies have generated sufficient data for evaluating these global personality predictions. Empirically, evidence suggests gender differences in most aspects of personality—Big Five traits, Dark Triad traits, self-esteem, subjective well-being, depression and values—are conspicuously larger in cultures with more egalitarian gender roles, gender socialization and sociopolitical gender equity. Similar patterns are evident when examining objectively measured attributes such as tested cognitive abilities and physical traits such as height and blood pressure. Social role theory appears inadequate for explaining some of the observed cultural variations in men's and women's personalities. Evolutionary theories regarding ecologically-evoked gender differences are described that may prove more useful in explaining global variation in human personality.

Preschool children and chimpanzees prefer to pay to watch punishment of antisocial other, instead of saving effort or money and stop watching
Preschool children and chimpanzees incur costs to watch punishment of antisocial others. Natacha Mendes, Nikolaus Steinbeis, Nereida Bueno-Guerra, Josep Call & Tania Singer. Nature Human Behaviour (2017). doi:10.1038/s41562-017-0264-5
Abstract: When misfortune befalls another, humans may feel distress, leading to a motivation to escape. When such misfortune is perceived as justified, however, it may be experienced as rewarding and lead to motivation to witness the misfortune. We explored when in human ontogeny such a motivation emerges and whether the motivation is shared by chimpanzees. Chimpanzees and four- to six-year-old children learned through direct interaction that an agent was either prosocial or antisocial and later saw each agent’s punishment. They were given the option to invest physical effort (chimpanzees) or monetary units (children) to continue watching. Chimpanzees and six-year-olds showed a preference for watching punishment of the antisocial agent. An additional control experiment in chimpanzees suggests that these results cannot be attributed to more generic factors such as scene coherence or informational value seeking. This indicates that both six-year-olds and chimpanzees have a motivation to watch deserved punishment enacted.

Knowing one would receive the answers to anagrams made them persist for less time trying to solve the task

Abstract: Our willingness to persist in problem solving is often held up as a critical component in being successful. Allied against this ability, however, are a number of situational factors that undermine our persistence. In the present investigation, the authors examine 1 such factor—knowing that the answers to a problem are easily accessible. Does having answers to a problem available reduce our willingness to persist in solving it ourselves? Across 4 experiments, participants (university students from a large Canadian University) solved multisolution anagrams and were either provided the answers after giving up (and knew they would receive the answers) or not. Results demonstrated that individuals persisted for less time in the former condition. In addition, participants did not seem to be aware of the effect that answers had on their decisions to quit. Implications for our understanding of the role that access to answers has on persistence across a number of domains (e.g., education, Internet) are discussed.

Exposure to male sexual scents (androstenone) influences women’s drinking (they drink more)
Tan, R., & Goldman, M. S. (2017). Exposure to male sexual scents (androstenone) influences women’s drinking. Experimental and Clinical Psychopharmacology, 25(6), 456-465. http://dx.doi.org/10.1037/pha0000162
Abstract: In a demonstration of a heretofore unknown motivational pathway for alcohol consumption, we recently showed that exposure to scents emitted by human females during the fertile phase of their menstrual cycle could increase men’s drinking. The current study examined the reverse: whether exposure to male sexual scents (androstenone) would increase women’s drinking. One hundred three female participants were primed with either androstenone or a control prime (plain water) camouflaged as a men’s “cologne.” They then completed a laboratory assessment of beer consumption and related measures. (Nonalcoholic beer was used for methodological and safety reasons.) Results indicated that females exposed to the androstenone prime drank significantly more than those exposed to the control prime. Social and sexual expectancies taken subsequent to drinking (to avoid unwanted manipulation influences) were correlated with drinking in the primed group but not in the neutral group, supporting the idea that information-processing pathways related to alcohol use had been engaged in the primed group. Few females were ovulating, precluding assessment of the effects of fertility on this process. Because of the centrality of sexual signaling to fundamental evolutionary/biological forces, these results indicate a potentially powerful influence on alcohol consumption that calls for continued investigation.

The Geography of Poverty and Nutrition: Food Deserts and Food Choices Across the United States. Hunt Allcott, Rebecca Diamond, Jean-Pierre Dubé. NBER Working Paper No. 24094. http://www.nber.org/papers/w24094
We study the causes of “nutritional inequality”: why the wealthy tend to eat more healthfully than the poor in the U.S. Using two event study designs exploiting entry of new supermarkets and households' moves to healthier neighborhoods, we reject that neighborhood environments have economically meaningful effects on healthy eating. Using a structural demand model, we find that exposing low-income households to the same food availability and prices experienced by high-income households would reduce nutritional inequality by only 9%, while the remaining 91% is driven by differences in demand. In turn, these income-related demand differences are partially explained by education, nutrition knowledge, and regional preferences. These findings contrast with discussions of nutritional inequality that emphasize supply-side issues such as food deserts.

The married are more satisfied [...] suggesting a causal effect at all stages of the marriage, from pre-nuptual bliss to marriages of long-duration
How’s Life at Home? New Evidence on Marriage and the Set Point for Happiness. Shawn Grover, John F. Helliwell. Journal of Happiness Studies, https://link.springer.com/article/10.1007/s10902-017-9941-3
Abstract: Subjective well-being research has often found that marriage is positively correlated with well-being. Some have argued that this correlation may be result of happier people being more likely to marry. Others have presented evidence suggesting that the well-being benefits of marriage are short-lasting. Using data from the British Household Panel Survey, we control individual pre-marital well-being levels and find that the married are still more satisfied, suggesting a causal effect at all stages of the marriage, from pre-nuptual bliss to marriages of long-duration. Using new data from the United Kingdom’s Annual Population Survey, we find that the married have a less deep U-shape in life satisfaction across age groups than do the unmarried, indicating that marriage may help ease the causes of the mid-life dip in life satisfaction and that the benefits of marriage are unlikely to be short-lived. We explore friendship as a mechanism which could help explain a causal relationship between marriage and life satisfaction, and find that well-being effects of marriage are about twice as large for those whose spouse is also their best friend.
