You've answered your own question. Actual wisdom is difficult to attain and often times difficult to further express in spoken or written language (ie. "tacit knowledge", if you believe such a thing exists I suppose). The kind of wisdom you DO attain may not be socially acceptable, either. But, you still want to have the appearance in front of your friends, colleagues and potential "partners" that you are somehow wise. So you turn to statistics, and damn lies that follow.
