You missed the main point, although the studies you mentioned could be ground breaking stuff, there is always the chance of academic fraud. I have worked along side of a few over educated idiots, their PHD's allowed them to pretend to be experts and they did a lot of damage until others proved what many of us suspected.
I am not dismissing your examples but I highly doubt any study works for billions of people scattered across a large globe and from competitive religions, cultures etc. Still, it might be a good read, I will withhold judgement.
