In the 1980s, two social psychologists–Rich Petty and John Cacioppo–devised a new way to make sense of persuasion: the Elaboration Likelihood Model. Their work came on the heels of an era in psychology when people were fed up with persuasion research. The old studies were a mess, and it wasn’t clear if it was even possible to understand how persuasion works. In the course of studying for an exam in graduate school, Rich and John started sketching out some ways to make sense of things. Over the next decade or so, those ideas blossomed into a fully formed theory that continues to inspire persuasion research today.
In this episode, I bring you up to speed on the Elaboration Likelihood Models and the incredible stories of happenstance that made it all happen. The foundation of the episode includes an interview with Rich Petty, a psychology professor at Ohio State University. In the latter half of the episode, we hear from Pablo Briñol, psychology professor at Universidad Autónoma de Madrid. Plus, there are some bonus words from Bob Cialdini.
