Résumé

Human pro-sociality towards non-kin is ubiquitous and almost unique in the animal kingdom. It remains poorly understood though a proliferation of theories has arisen to explain it. We present evidence strongly consistent with a set of theories based on group level selection of cultural norms favouring pro-sociality. The evidence is drawn from survey data and from laboratory treatment of experimental subjects. The findings provide support for cultural group selection as a significant contributor to human pro-sociality.

One Sentence Summary:  Consistent with theories of cultural group selection, increases in competition increase trust levels of individuals who: 1. work in competing firms, 2. live in states were competition increases, 3. move to sectors where competition rises and, in the lab, get placed into groups facing higher competition.
