On the wisdom of crowds......................

"The wisdom of crowds in the market, as everywhere else, does not arise from the wisdom of each and every member of the mob. It comes from the diversity of idiotic, ill-considered, and just plain dumb opinions held by everybody, which, by some thankful magic of human nature, usually tend to cancel each other out and supply a workable if not entirely transparent answer. It’s when we have only one lunatic, or a small handful, making value decisions that we tend to get the silly answers."
