#100: A Unified Model of Persuasion

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 ...
