Strong institutions reduce in-group favoritism

Ineffective social and political institutions make people more likely to favour their family and own local social group, while good institutions make them more likely to follow impersonal rules that are fair to everyone, suggests a forthcoming study in the journal Human Nature.

A series of experiments found that people in societies with supportive government services, food security and institutions that meet their basic needs were very likely to follow impartial rules about how to give out money. By contrast, those without effective, reliable institutions showed favouritism toward members of their local community.
