RJ's comment #30 reminds me of a joke I heard recently which is actually quite on-point.
Two Taliban fighters are talking in Afghanistan. One of them comments, "Those American Marines are such incompetents, their marksmanship is pathetic!" The other one asks, "How do you know that?" And the first replies, "Well, I've talked to a bunch of our guys who were shot at by them - the Marines missed every time!"If you don't see the connection, think about it for a bit. Hint: Selection effects.
