MICHAEL MORRIS: I’ve been able to translate my particular area of behavioral science, which is called cultural psychology, into a toolkit for leaders who want to lead through culture, who want to use culture as a way of rallying collective action or pull on people’s cultural wiring in order to orchestrate a cultural change. MICHAEL MORRIS: If using situational cues is the short-term approach to managing culture, the longer-term approach to molding a culture is learning the social signals that update people’s cultural codes. CURT NICKISCH: That’s Michael Morris, a professor at Columbia Business School and the author of the new book, Tribal: How The Cultural Instincts That Divide Us Can Help Bring Us Together.
