Laughing, grooming, and pub science.

Abstract:

:On the basis of naturalistic observations of people conversing and laughing in pubs, a new study suggests that the 'grooming-at-a-distance' of laughter provides a three-fold increase in grooming group size, potentially explaining how hominins evolved social groups that are considerably larger than those of other primates.

  • False memories and confabulation.
