Like most of pop psych.
There's a predatory ecological niche in every society. Very common in nature too. Altruism is less common than predation in nature, it seems.
Though in the workspace, you may be onto something.
Hopefully that bullshit virtue signalling went away.
The way I see it there's a selection bias at play here. The kind of psychopaths who are repeat offenders are the ones who get caught, so of course we notice them.
We don't notice the ones who don't get caught.
That doesn't mean that they're any less ruthless and destructive to society -- they're just lucky / more functional.
In my mind I view white collar crime to be the greatest evil in society because it is the thing that enables all of the petty/violent crime that we abhor. Part of the reason that it's so evil to me is for that very reason, and that the perpetrators of it are able to pass themselves off as functional individuals who participate in society like you and I do, and are able to use the system against itself to perpetuate their crimes.
If someone does appear who can identify them, they are quickly exited from the company via various means depending on the individual: pair them with a particularly distasteful partner/manager, make their job impossible via passive means, or enable them to humiliate themselves.
The only real symptom is that there is no one around them that competes with them in their self-perceived core competency, and they never seem to put a foot wrong. Once the are in a high position, anyone who complains about their behavior is said to be attempting to climb.
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.
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.
