Also I think it is education and historical practice of misusing math. This I've seen for decades: in the life sciences in general, they don't understand the mathematics behind statistics. Very consistently. My theory is this arose from the inability to actually do mathematically valid studies on real people - Hitler tried it but in most societies it's frowned upon. Being used to ad-hoc, invalid math abuse becomes habit. What I've noticed is that even when the opportunity to use math properly, the idea seems offensive to many - the get very defensive, even hostile. I think that is part of the culture that is instilled by their education.
