Taleb is using the idea that in order to create a world where, barring extreme circumstances, such as birth defects and disease, people are of roughly equal ability we have to pretend that, baring extreme circumstances, all people are of roughly equal ability and attack any information that points out anything to the contrary. The idea being that by believing a reality is true and attacking anything that contradicts that belief we can make it true.
