In 1957, Leon Festinger published A Theory of Cognitive Dissonance. Along with a collection of compelling experiments, Festinger changed the landscape of social psychology. The theory, now referenced constantly both in and outside of academic circles, has taken on a life of its own. And it\\u2019s still informing new research and analysis more than 60 years later.

For the grand 20th episode of Opinion Science, I want to give you an insider\\u2019s look at the theory\\u2013its inspiration, the people involved, the classic studies, and the remaining controversies.

Throughout the show you\\u2019ll hear from people who have studied cognitive dissonance and who knew the infamous Leon Festinger: Elliot Aronson, Joel Cooper, Jeff Stone, April McGrath, and Mike Gazzaniga.

To learn more about cognitive dissonance, check out these two books written by two of our guests: Cognitive Dissonance: 50 Years of Classic Theory and Mistakes Were Made (but Not by Me).
