Excellence is a high cost but low variance character trait. Taking for example an excellent powerlifter you would expect to see them slowly build upon their total over many years and may just edge out the next best. What moves the dial in human history is high variance behaviour as seen in geniuses and it is imperative that we recognise much of our progress has been borne from the minds of eccentric and appalling people. One of three men behind the invention of the semi-conductor, William Shockley, was a eugenicist but you would have to be some kind of a massochist to try to argue that the human race would have been better off had he been shunned from academia. These people must in some way be tolerated as the rewards are so great. We want non-conformists to be given the resources required to benefit from their potential, but excellence is serving as a barrier to the contribution of genius.
