Psychologist Michele Gelfand talks about her book, Rule Makers, Rule Breakers, with EconTalk host Russ Roberts. Gelfand distinguishes between loose cultures and tight cultures--the degree to which culture and regulation restrict behavior or leave it alone. Gelfand explores the causes of why some cultures are tighter than others and the challenges societies face when culture is too tight or too loose. She also applies these ideas of cultural tightness and looseness to corporate mergers and family life.
