RE: Highly Suspicious of Meta-Analysis

What I described is indeed a cheat, if done consciously. But it is also possible to do it unconsciously. If one is more or less familiar with the literature and one has preconceived notions of "truth" one may well have an unconscious tendency to invent criteria that rules in one's favorite research and rules out one's disliked research without even realizing what one is doing.

One can avoid this problem (but not be able to prove that one has avoided it) by coming up with the criteria before reading any reports on the subject. Unfortunately, this is unlikely to be very effective, because if one has no familiarity with previous work in the field one is unlikely to even be aware of the problems one should be looking for. One is trying to be an "unbiased expert" but there is no such thing as an unbiased expert.

Hence the debate goes on and on....
