The spinning dancer and the actual evidence

Steven Levitt questions (quite convincingly, despite the small sample size and possible selection issues) the main "predictions" associated with the direction people see this ballerina spin. Levitt (who also sees the dancer turn only clockwise, as I do) shows that probably all associations in the article were reversed and the left column should have been the right column (next to that, it also appears that it isn't even true that most people see the dancer turn anti-clockwise)... I thought so, since I deemed most of them speculations, to start with. Well, too bad for the risk taking behaviour, that one I did not mind :-).
