Specific example: In the car insurance paper, which was covered by Data Colada, there was agreement among all the four authors that Ariely himself was the only person to touch the data. That data (IIRC) was completely fabricated.
I’m happy to edit this comment and my original one if those details are wrong. I’ll give Ariely a presumption of innocence which he does not deserve and indeed which I suspect he abuses in research integrity investigations.

At the end under “replies” Dan says himself that he was the person in touch with the insurer. It really beggars belief to imagine that there was someone at the insurer who fabricated a dataset which perfectly tells the BS story of this paper.
Also note that another of the four authors (Gino) will soon be fired from HBS for fabricating data in a series of studies.
