Not entirely Wolfgang.

Yes, there is a terribly misleading graph in study 2, and yes there are actual scientists who find fault with the method, but I strongly suspect that those finding fault are driven by politics. Their objections have been publicly defended by the authors (Wikipedia, among others, has an extensive analysis -- and one should read the arguments between Wikipedia editors as well as the current form of the article to get the full flavor). It is still true that the same methods are widely used, and unchallenged, in other studies.

I have read widely on this, and still believe that this argument is a political one.
