razib, great post. Overall, if there's a particular weakness among enthusiasts (and "experts") in rational thinking, it's a tendency towards overreductionism. Way to often the discussion here goes from Most X are Y to let's discuss why X is Y. It can be revealing to analyze the subset of X that aren't Y, as well as the overall distribution of X according to how much they are or aren't Y. But these other analyses are done or discussed much here at OB, or at most similar sites.
