Who is having more and better sex? The Big Five as predictors of sex in marriage

Prior research has been somewhat inconsistent in demonstrating links between personality and sexual functioning. We pooled the data from three independent daily-diary studies of newlywed couples to examine the association between individuals’ Big Five traits and the probability of sex on a given day; we also pooled the data from the two studies that assessed satisfaction with sex to examine the association between these traits and individuals’ satisfaction with sex when it occurred. Couples with wives high in agreeableness engaged in more frequent sex. Husbands low in openness or neuroticism and wives low in neuroticism reported increased satisfaction with sex when it occurred. Partner personality was unrelated to satisfaction with sex when it occurred.     

Do age stereotypes as social role expectations for older adults influence personality development?

Age stereotypes as social role expectations for older adults were hypothesized to influence personality development in later life for specific stereotype domain x personality trait combinations. N = 965 participants aged 50–60 from the Midlife Development in the U.S. (MIDUS) study provided ratings about “people in their late sixties” in four domains at T₁ and completed a personality questionnaire at T₁ and at T₂ ten years later. Personality at T₂ was regressed on age stereotypes and personality at baseline. Age stereotypes in the domains Family/Relationships and Wisdom were related to changes in both Agreeableness and Extraversion over ten years. The findings provide tentative support for the role of positive age stereotypes in personality development in older age.     

Not as Different as We Want to Be: Attitudinally Consistent Trait Desirability Leads to Exaggerated Associations Between Personality and Sociopolitical Attitudes

Research connecting sociopolitical attitudes to personality typically relies exclusively on self‐report measures of personality. A recently discovered mechanism of bias in self‐reports highlights a particular challenge for this approach. Specifically, individuals tend to report exaggerated levels of a trait to the extent that they view that trait as desirable. In a community sample of 443 participants, differences in sociopolitical attitudes were associated with differences in the extent to which individuals provided biased self‐reports for a given trait (relative to trait levels indicated by peer‐report or an objective measure) as well as differences in views of the desirability of that trait. Further, the tendency to misrepresent traits in a manner consistent with one's sociopolitical attitudes was mediated by differences in views of trait desirability. Thus, although meaningful personality differences exist among those with differing sociopolitical attitudes, those differences may not be as large as people with opposing sociopolitical attitudes might like them to be.
