Interesting observation, and on the mark, except I think sometimes that particular sort of reasoning process is more strategy than belief. Evolutionists use it (the postulator defines only a and b as possible. a is made so outlandish as to be unacceptable to "common sense," so the answer must be b), religious fanatics use it.... However, I think strategists do it consciously and maliciously, and represent a whole different sort. I've seen the "black or white" argument used by people I knew (because the bullseyes they were aiming for required precisely specific knowledge) had to know the truth as Truth, and simply found it unpalatable. I guess those people feel validated if they can build a crowd of other non-reasoning believers around them. Hmmm. Maybe not so different at that.
