Behavioral economist Dan Ariely gets the RSA Animate treatment.
Known for his work on human motivation, or as he puts it in this video, our "flexible cognitive psychology," his most recent book, "The Honest Truth about Dishonesty," goes beyond simple admonishments against corner-cutting to point out the ways cheaters - that would be you and me - can rationalize what we think (as long as we're thinking it!) and how cheating can be discouraged.
Prior to his most recent book, Ariely wrote the best selling "Predictably Irrational: The Hidden Forces that Shape our Decisions."
