How Coffee Affects Men And Women Differently
a meeting becomes stressful, does it help, or make things worse, if team members drink lots of coffee? A study by Lindsay St. Claire and colleagues that set out to answer this question has uncovered an unexpected sex difference. For two men collaborating or negotiating under stressful circumstances, caffeine consumption was bad news, undermining their performance and confidence. By contrast, for pairs of women, drinking caffeine often had a beneficial effect on these same factors. The researchers can't be…

Do people avoid situations that enable them to deceive others?
formation advantage enables people to benefit themselves by deceiving their counterparts. Using a modified ultimatum bargaining game with an exit option, we find that people are more likely to avoid settings enabling them to privately deceive their counterparts than settings which do not enable deception. This tendency is explained by people's reduced desire to become responsible for the other's outcomes when deception is possible. Results of three experiments show that people avoid entering a setting that enables deception by appearing…

How do conscientious people handle unemployment differently?
nscientious individuals tend to achieve more and have higher well-being. This has led to a view that conscientiousness is always positive for well-being. We hypothesize that conscientiousness could be detrimental to well-being when failure is experienced, such as when individuals become unemployed. In a 4-year longitudinal study of 9570 individuals interviewed yearly we show that the drop in an individual’s life satisfaction following unemployment is significantly moderated by their conscientiousness. After 3 years of unemployment individuals high in conscientiousness (i.e. one…

Do those who have less give more?
s: Lower social class (or socioeconomic status) is associated with fewer resources, greater exposure to threat, and a reduced sense of personal control. Given these life circumstances, one might expect lower class individuals to engage in less prosocial behavior, prioritizing self-interest over the welfare of others. The authors hypothesized, by contrast, that lower class individuals orient to the welfare of others as a means to adapt to their more hostile environments and that this orientation gives rise to greater prosocial…

Are narcissists aware they are narcissists?
a Scott Barry Kaufman: Those scoring high in narcissism tended to rate themselves as more intelligent, physically attractive, likeable and funny than others. Interestingly, they also rated themselves as having higher levels of negative aspects of narcissism, such as being power-oriented, impulsive, arrogant and prone to exaggerate their abilities! Therefore, narcissists are aware they are narcissists. There was also a strong positive correlation between narcissism and having a reputation for narcissism: narcissists were definitely perceived as narcissists. While other people…

Should you trust your gut when deciding whether a neighborhood is safe or not?
a Science Daily: It's an unfamiliar neighborhood and you find yourself in the middle of a bunch of streets and buildings you've never seen before. Giving the environment a quick once-over, you make a snap decision about whether you're safe or not. And chances are, that first 'gut' call is the right one, say Binghamton University researchers Dan O'Brien and David Sloan Wilson in an article published in the current issue of Journal of Personality and Social Psychology. And: Through…

Do more women get married when it’s hard for them to find a job?
ack labor market conditions for women relative to men increase the marriage rate in the USA. This paper examines the long-term consequences of such marriages. Despite the significant effect on marriage timing, labor market conditions experienced in youth do not affect the probability that a woman will marry by the age of 30. Further, labor market conditions at the time of marriage are uncorrelated with the probability of divorce, spouses’ characteristics, or the number of children. These findings suggest that…

Poor Fitness Is Contagious
e increase in obesity over the past 30 years has led researchers to investigate the role of social networks as a contributing factor. However, several challenges make it difficult to demonstrate a causal link between friends’ physical fitness and own fitness using observational data. To overcome these problems, we exploit data from a unique setting in which individuals are randomly assigned to peer groups. We find statistically significant positive peer effects that are roughly half as large as the own…
