Right. It's all very scientific (pseudo scientific?), but I'll wait till I see this article printed in a respected scientific journal.  I see no attribution by the writer. Until then, I will regard it as the answer to every politician's prayer. That is, "please Mr./Ms. public, don't complain about how my policies are not working for you. That bothers me and causes me stress. I like to avoid stress. So good luck with what you feel like complaining about.. You would only be hurting yourself.
