I don't disagree. But I don't think personal anecdote is a sufficient answer. You could criticize the quality of the research (in more specific terms than "pop-sci") or present contradictory evidence and I'd have no problem with it. Simply attacking a guy in a casual discussion that is not particularly rigorous for posting a citation you deem insufficiently rigorous without further explanation I do not think is fair.
