You would think so, right? But funnily enough, whenever we find a new type of hominid that existed around us (neanderthals, denisovans, homo florensiensis), we find out that humans interbred with them and they are a part of our modern human DNA.
I bet humans learned to "other" things that look like humans so they could do things like avoid the sick and dead, dehuminize other tribes to kill them in war. All the very human things we do now.
It would be a evolutionary benefit to fear / avoid any person that is behaving strangely in certain distinct ways. Could be a dangerous transmittable disease, i.e. rabies etc.
I doubt that premise. Neanderthals looked different, but not uncanny valley. Horror and fear may have been involved sometimes, but so was sex and competition... Neanderthals probably just looked like big chinless people
According to commercial genetics testing, I'm more Neanderthal than 90% of other people that used the same major company. My ancestors were into some kinky 👉👌
Our instincts draw from pretty far back in our biological origins as well. The notion of mimiclike predators is pretty damned ancient and likely a factor for very earliest common ancestry.
Psychopath is derived from Ancient Greek... And even besides that, laymen generally use the term to describe ASPD despite the two conditions not being entirely the same. Don't be obtuse.
The best non-DSM category for socio/psychopath I've come across is the lack of affective empathy, but intact cognitive empathy. (non-DSM because that's just symptom clusters not aetiologies, you quite literally need to have broken laws to be diagnosed with ASPD). Then you have a look at what skills are useful to have as a surgeon, like not flinching when you cut into people, and their character traits including their bedside manners, yep there's plenty of perfectly integrated psychopaths around. Same goes for pyromaniacs fire departments are full of them, you only ever hear about the ones who don't get the curve.
Alternate theory: The human brain is reacting to unfamiliarity and not alien features. We strongly associate Uncanny Valley with things not-quite human but it’s my thinking that it’s a tribal thing. Nowadays we see a ton of faces of all variations but I bet when we were hunter gatherers, we only saw features of our own tribe. The moment you meet another tribe, I’d bet this response is to create fear of the unrecognized human. It’s also probably there as a punishment mechanism for us seeing faces in everything.
The times that the uncanny effect hit hardest is when you think something is human or is a face potentially before finding out you’re wrong. So that’s my basis for thinking its there to keep us from being mistaken.
