A fair point: there may be three unique articles referred to in my list there, rather than four. An additional fake paper on which I could have added to that list revolves around an apparently-modified paper shredder. However (!) there are a bunch of other Ariely articles which are extremely suspicious and which are suspected of being fake. At this point I would say everything he has ever written should be assumed to be faked. I expect a broader investigation will reveal more fraud. Apparently Duke doesn't care enough but hopefully some renewed attention to the case will force them to take action.
