Yes. The experiment proves that we are in astrology stage of development regarding mental illnesses. It doesn't mean that stars or planets do not exist. It just means that astronomy is yet to be born. Psychiatry awaits its Copernicus.

btw, I don't see how could you explain the second part of the experiment where were no fake patients at all as "gaming". If a mere expectation of a fake patient screws the results so much; your methods are garbage. This and other counter-arguments are mentioned on the wiki-page.
