In my teaching work and on this blog, I have often referred favorably to the work of behavioral economist Dan Ariely who devised ingenious experiments to tease out human behaviors and motivations. (See here for the posts where I have discussed his work.) I have recommended his book Predictably Irrational which, as the title succinctly suggests, argued that while people are often irrational, their irrationality is not random. He has also given very popular TED talks.
A lot of his research dealt with the issue of honesty: what corners people are willing to cut, by how much, and how they view themselves. So I was disappointed to read that he may the latest example of an academic who has been sloppy or worse in the way that he has conducted his research, throwing his work into doubt.
