Dr Timothy Levine on deception: Truth-Default Theory, spotting liars and how not to be wrongfully convicted (#14)

Can you spot a liar? 

If I showed you videos of ten people who were asked if they had cheated on a test, do you think you could spot the five liars? 

You’d be surprised to know that your ability to spot the liars would be little better than a coin toss. 

But this should not be a surprise. After all, we’ve all been burnt at some point. We all know what it feels like to be fooled. 

Why are we so bad at spotting liars? 

Why do we not notice when our partners are cheating? 

Why do we only detect fraud after the damage is done? 

Why do we fall for scams or get-rich-quick schemes? 

If you’ve read Talking to Strangers by Malcolm Gladwell then you might already by familiar with the idea of Truth-Default Theory. We are super excited by the opportunity today to dig deeper into deception and Truth-Default Theory by talking to the very person who developed the theory! 

Dr Timothy Levine is one of the leading researchers in the area of deception and he is an expert on interpersonal communication.  He is Distinguished Professor and Chair of Communication Studies at the University of Alabama at Birmingham (UAB). Dr Levine’s teaching and research interests include deception, interpersonal communication, persuasion and social influence. He has published more than 140 journal articles. His research has been funded by the National Science Foundation, Department of Defence, and Department of Justice. His work has received press coverage from New York Times, Washington Post, NPR, NBC, CNN, Discovery Chanel, and National Geographic.  

His latest book was released last year. I would highly recommend this book to anyone interested in the topic of deception. The book is called Duped: Truth-Default Theory and the Social Science of Lying and Deception. The book details Dr Levine’s 30-year program of research on deception which has led to the development and testing of Truth-Default Theory. 

We hope you enjoy this eye-opening conversation with Dr Timothy Levine.

If you are too full of yourself and too worried about your own image and own ego you are not going to be very good at relating to other people…being a good communicator has to be to some extent be about the other person”

“What I like about deception is the puzzle…I like that it is not well understood…that gives me a chance to make a splash with my research.” 

“Generally, the closer you are to somebody, the more you think you can tell they are lying, the more you believe them and the more you miss the lies.”
