In Response To: Selection bias (phil Simborg)

Weren't all problems already one's that SW was known to get wrong?

Another analogy:

A pro (tour) golfer plays a round and shoots a decent score (say 69 on a par of 72). You select the shots he messed up, e.g. missed a 3 foot putt on hole number 5, took two shots to get out of the sand on hole #8, hit his drive into the woods on hole #13. Then you ask a top amateur to repeat only those situations where the pro screwed up. The Am does better. What are we to conclude?
