Relax a little, the poster outright said it was a guess. They were just offering a POSSIBLE explanation based off of their personal views, no need to pull out your Empiricism 101 textbook.
My guess, actually, is that people who have done the work would not view this as a "possible explanation". It seems about as useful as speculating that "hey, maybe the earth is flat?"
But you never know, that's why I asked, hoping that someone OP or otherwise who has experience in the field would comment.
TFA is specifically taking about genetics and brain scans, which makes me curious as to how that would be reconciled with this "theory" about bad experiences, if indeed the OP was aware of the content of the article at all.
