Decades of studies identify personality traits as an important predictor of life outcomes. However, previous investigations of personality-outcome associations have not taken a principled approach to covariate use or other sampling strategies to ensure the robustness of personality-outcome associations. The result is that it is unclear (1)...
Several studies have suggested that the rank-order stability of personality increases until midlife and declines later in old age. However, this inverted U-shaped pattern has not consistently emerged in previous research; in particular, a recent investigation implementing several methodological advances failed to support it. To resolve the matter, we analyzed data from two representative panel studies ...
We propose a broadly applicable empirical approach to classify individuals as time-consistent versus native or sophisticated regarding their self-control limitations. Operationalizing our approach based on nationally representative data reveals that self-control problems are pervasive and that most people are at least partly aware of their limited self-control. Compared to naifs, sophisticates have ...
Agency and communion are the two fundamental content dimensions in psychology. The two dimensions figure prominently in many psychological realms (personality, social, self, motivational, cross-cultural, etc.). In contemporary research, however, personality is most commonly measured within the Big Five framework. We developed novel agency and communion scales based on the items from the most popular ...
Declining response rates have made traditional, probability-based sampling methods more resource-intensive and thus more expensive. Studies of population subgroups are particularly vulnerable to this trend, as smaller group sizes as well as other factors often make these groups "hard-to-reach" or "hard-to-survey". In response, researchers have increasingly relied on network...
Risk preference impacts how people make key life decisions related to health, wealth, and wellbeing. Yet the evolutionary roots of human risk taking behavior remain poorly understood. I will present two studies on risk preferences in chimpanzees, one of our closest living relatives.In the first study, we investigated whether chimpanzees (N=13) differentiate between social...
Economists increasingly recognise the importance of personality traits for socio-economic outcomes, but little is known about the stability of these traits over the life cycle. Existing empirical contributions typically focus on age patterns and disregard cohort and period influences. This paper contributes novel evidence for the separability of age, period, and cohort effects for a broad range of personality ...
