I don't really buy much of this. Is paranoia really a genetic trait? The video seems to suggest that evolution favours paranoia, but here we all are for the most part not paranoid of everything. There is a price for false positives, that's energy wasted running from the wind in the trees or a distrust of others thats results in fewer mating opportunities for example. The truth just might save your life, but seems to me the paranoid as just as likely to miss the truth because they see patterns and assign meanng where there are none and they end up overlooking the simpler explanation. So yah. I'm calling bullshit.

I'm not a big fan of how easily he interchanges the terms "paranoia" and "conspiracy theory".
Paranoia is a real mental health condition that falls under the category of anxiety.
If it was such an "evolutionary trait" then it would be so readily and successfully treated with therapy and medicine.
It also shares a common trait, almost everyone who suffers from paranoia anxiety does not wish to continue suffering from its symptoms. I would assume that if it were such a positive evolutionary trait, then it would have been a more desirable ailment to suffer from.

Just because it's an evolutionary trait, doesn't mean we want it. A hairy male for instance why be able to stand the cold better, but doesn't mean it's a trait him or his potential mates like.

Things like paranoia, or even community, to depression can and do have several links to an evolutionary advantage. The issue here isn't that paranoia is good or extreme, it's that the levels at which they express themselves in certain people are and can be well above normal. There is a thing as healthy paranoia where we generally fear things we don't know as a preservation technique. However, the level of wanton paranoia expressed by manic conspiracy theorists is not healthy. Much the same as sex is good, but a sex addiction is bad. Or sugar . . . we love the taste of sugar but in a time of plenty, it works against us.
