Friendship making orientation as indexed by preferences for wide networks and intimacy with many friends: Structure and validity of a new construct
Friendships help people achieve many fundamental adaptive functions, such as forming coalitions and successful alloparenting. As such, one might theorize that humans are designed to seek out and maintain as many friendships as possible. However, with time and energy as finite resources, humans face a unique challenge in determining the number of friendships they can sustain - do they prioritize maximizing friendship quantity (potentially at the e…
Helping People in Times of Need Cultivates Empathy Over Time
Why is lower social class often associated with greater empathy? We test whether less wealthy people experience more challenges, thereby motivating them to help others as a means of securing future social support, and, in turn, cultivating empathy over recurrent experiences. Study 1 ( N = 513) showed that wealth was negatively correlated with empathy through fewer challenges and less helping. Study 2 ( N = 915) replicated this effect while reveal…
Sources of fitness interdependence associated with shared fate and cooperation in a small-scale horticultural society
What is reciprocity? A review and expert-based classification of cooperative transfers
Empathic concern motivates willingness to help in the absence of interdependence
Previous research suggests that empathic concern selectively promotes motivation to help those with whom we typically have interdependent relationships, such as friends or siblings, rather than strangers or acquaintances. In a sample of U.S. participants (collected between 2018 and 2020), our studies not only confirmed the finding that empathic concern is directed somewhat more strongly toward interdependent relationship partners, but also showed…

Food scarcity and disease concern reduce interdependence when people eat together
Food sharing is central to the human experience, serving biological and sociocultural functions. Historically, food sharing has allowed people to manage food shortages, creating positive interdependence among those who pool calories and other sources of risk. However, sharing food may lead to negative outcomes when food is scarce, or when there is a threat of disease. We found that sharing food (compared with sharing pencils) led to reduced coope…
