Andy Luttrell: Pro’s and Con’s of Persuasion When Issues are Moralized

Oct. 5, 2020

Andy Luttrell, PhD is an assistant professor of psychological science at Ball State University and the podcaster/host of Opinion Science, one of Kurt and Tim’s favorites.

Andy’s research centers on people’s opinions, including when and how attitudes change. More importantly, Andy is curious about what happens when people moralize their attitudes and how moral arguments can sometimes be compelling and sometimes backfire. Our conversation focused on these areas and we loved the research Andy presented.

We were particularly interested in hearing about how people who based their positions on careful analysis tend to be the ones who open enough to be persuaded with the right argument.

So our willingness to be open to a fresh idea is in part based on how strong or weak the arguments were in coming to our own conclusions. We found the research fascinating that indicates that people with weak arguments are harder to persuade to new ideas. That was a head-scratcher.

Our discussion also covered some thoughtful positions on the so-called Replication Crisis and Andy’s first-hand experience with replication – and non-replication – was insightful.

We also want to remind you that Andy’s podcast, Opinion Science, is one of our favorite podcasts – period. We highly recommend it.
