Maybe because statisticians (with their degree and correspondent IQ) never did reach really clever persons without a degree that I've known to perform an IQ test... or because they didn't choose some of the STEM degree holders, authors of real horror histories at work, or with the brain of a vegetable, that I did know. Who knows :) Anyway, don't want to discuss about if I'm wrong or insecure, but about the topic, have a nice day!
