In Your Eyes Only? Discrepancies and Agreement Between Self- and Other-Reports of Personality From Age 14 to 29

Abstract

Do others perceive the personality changes that take place between the ages of 14 and 29 in a similar fashion as the aging person him-or herself? This cross-sectional study analyzed age trajectories in self-versus other-reported Big Five personality traits and in self-other agreement in a sample of more than 10,000 individuals from the myPersonality Project.Results for self-reported personality showed maturation effects (increases in extraversion, conscientiousness, openness to experience, and emotional stability), and this pattern was generally also reflected in other-reports, albeit with discrepancies regarding timing and magnitude. Age differences found for extraversion were similar between the self-and otherreports, but the increase found in self-reported conscientiousness was delayed in otherreports, and the curvilinear increase found in self-reported openness was slightly steeper in other-reports. Only emotional stability showed a distinct mismatch with an increase in selfreports, but no significant age effect in other-reports. Both the self-and other-reports of agreeableness showed no significant age trends. The trait correlations between the self-and other-reports increased with age for emotional stability, openness, agreeableness, and conscientiousness; by contrast, agreement regarding extraversion remained stable. The profile correlations confirmed increases in self-other agreement with age. We suggest that these gains in agreement are a further manifestation of maturation. Taken together, our analyses generally show commonalities but also some divergences in age-associated mean level changes between self-and other-reports of the Big Five, as well as an age trend towards increasing self-other agreement.Word count: 239

How people know their risk preference

“…59 It was also close to the agreement between self and other ratings among Facebook friends for personality traits. 60 Despite being very brief-a median of 10 words-the texts contained condensed, pertinent information. Our social judgment analysis showed that coders relied on cues such as regret, the number of risks listed for the last 12 months, and risk avoidance.…”

Personality Change: Longitudinal Self-Other Agreement and Convergence With Retrospective-Reports

“…The tendency for self-other agreement to be higher on extraversion and conscientiousness has been replicated often both cross-sectionally (Connelly & Ones, 2010) and across development (Göllner et al, 2017, Luan et al, 2017. Cross-sectional self-other agreement has been shown to increase from adolescence to young adulthood, mirroring the maturity principle of personality development (Rohrer, Egloff, Kosinski, Stillwell, & Schmukle, 2018). However, there have been fewer studies specifically on self-other agreement on personality trait change, and to our knowledge no studies in older adulthood.…”
