This is not saying it is debatable, it is politely saying it is almost definitely wrong, but still popular.

Not proven ≠ Wrong

It's true, a direct link hasn't been proven, and I was debating even mentioning that. Obviously that specific tendency alone isn't indicative of a homicidal individual. But I would speculate that it has something to do with dysfunction/dysregulation of the autonomic nervous system.

Yes, but that is the absence of evidence, commonly called on when the science hasn't been done.

If a theory/hypothesis remains not proven once the science has been repeatedly done in numerous attempts to prove it, very often it does mean it is wrong.

A mere two studies are cited in the Wikipedia quote you supplied as evidence of the supposed wrongness of the hypothesis.

Wikipedia is not often referenced in literature reviews as an exhaustive source of relevant studies.

It still seems like it could be correlated, but it shouldn't be used as a diagnostic measure or taken as a sign of something. It's more likely to be a sign of abusive parenting, but abusive parenting is also correlated with the psychopath behavior so it all ends up being correlated with each other.

Well there are is neurogenic bladder and congenital causes.

That is what I meant by the word debatable. I was trying to politely imply it's bullshit like 95% of psychology.
