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 ...

It was developed on the ground, but when political scientists put it to a rigorous test, they found that these brief conversations with voters were having a lasting impact (Broockman & Kalla, 2016).

On this episode, Dave shares his background in political campaigns and walk...

Daniel Kahneman was a titan in social science. He transformed our understanding of decision-making, he taught a generation about social psychology, he won a Nobel prize.

Along with the hosts of the podcast Behavioral Grooves, I interviewed Kahneman back in 2021, and we used that interview as a foundation of our podcast series, &...

Behavioral Economics was using psychology to understand economics, but what did economists and psychologists think about their unexpected marriage? Slowly, this fledgling field weathered a flurry of criticism from both sides as it doggedly held onto data-driven ideas about economic decision-making.
