If you've ever met a psychopath and seen their true colors, you will undoubtedly be convinced it's a real phenomenon. I have had the unfortunate experience of dealing with one myself. He showed all the hallmark signs. He urinated the bed frequently. He harmed animals when he was young. Specifically, he swung his pet gerbil around by the tail until the tail was severed. He threw a baby rabbit against a stop sign and killed it while his poor younger brother watched. He has grown up to be incredibly sadistic to the point where everyone I know has completely cut him off. I hope you never run into one. When you are talking to someone you believe to be decent, and you eventually realize what they are, what you're dealing with, it is a truly chilling experience.

What does urinating the bed have to do with it?

Not the GP, but it's debatably correlated, apparently.

> Although it remains an influential and widely taught hypothesis, subsequent research has generally not validated this line of thinking.[3][4]

[hirvi74]

Yes, that is why I wrote, "debatably."

[svnt]

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

[farts_mckensy]

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.

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.

[hirvi74]

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

[svnt]

It doesn’t.

[svnt]

Yes, that is dated and hasn’t been supported by more recent science.

[throwaway48476]

Recent psychology has been suffering from the replication crisis.

[svnt]

The replication crisis was recently discovered; this does not mean older science does not have the same challenges. Generally the problems that led to the replication crisis are worse the further back you go in time
