Michele Gelfand discusses her book "Rule Makers, Rule Breakers." (September 12, 2018)

Why, wonders University of Maryland psychology professor Michele Gelfand, are the clocks in Brazil so often wrong, while in Germany the clocks can be counted on? What explains the difference between New Zealand, where prostitution is legal, and Singapore, where chewing gum brings severe sanctions? In “Rule Makers, Rule Breakers,” Gelfand traces all of this, and so much more, to a single variable: the “tightness” of a culture. She explains the origins of tight (or loose) cultures in countries, in states, in companies, even in families—and then takes readers through the myriad implications, from politics to parenting. Join Leonard as he asks Michele about the research that went into this unique work.
