I'm more of the technical, math and physics persuasion..... and human behavior is not my forte. So I like my studies "un-flawed", based on solid premises. When a study or test is subject to controversy and opposing facts, I tend to shy away from anything borne from those studies or tests. IMO, you seem too willing to embrace something which has long been deemed flawed and controversial. It's an old and unwinnable argument, I'm afraid. As long as there are people with agendas or axes to grind, there will be tests, measures, graphs, and "proof" to make their points. Sad, really.
