Only on the CBS This Morning podcast, 2017 MacArthur fellow and psychologist Betsy Levy Paluck speaks with CBS News correspondent Vladimir Duthiers about her work understanding what drives human behavior and how social norms are determined. Paluck discusses her research studying how a soap opera could promote ethnic tolerance in Rwanda. Every year the John D. and Catherine T. MacArthur Foundation awards an unrestricted fellowship of $625,000 to talented individuals who have shown extraordinary originality and dedication in their creative pursuits and a marked capacity for self-direction.
