Five-year-olds affect the reputation of others through gossip
When it comes to selecting a cooperation partner, information about another person’s reputation – for example as a generous person or a miser – may come handy. Many animal species make reputation judgements, but only humans use gossip to pass on evaluative social information about others. Researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, show that five-year-olds but not three-year-olds reliably engage in such prosocial gossip.
