You're talking as if the chaos that the world is had been conceived my some illuminated mind based on the latest academic psychology research to be exactly like it is -- and not the reality that it is like that because of ton of different decisions, most of which were not at all based on any psychological research (or maybe based on what the person decided thought was a good idea with no real evidence for that), and even if some were and even in the unlikely case that these researches were correct that would make very little difference since that decision would instantly get mixed with the rest of the decisions in completely unpredictable ways.
