Edit - Addendum: The video title is quite clickbait-y. The video doesn’t want to debunk any “serious” science, but rather investigates how badly done research with no reproducability or horrible statistical significance is used to influence the discourse in favour of regressive politics.
Repeating your point dosn’t make it less wrong. You didn’t watch the video. You don’t get to judge it.
Please show the scientific process went in establishing that mistrust of strangers is a genetically evolved trait. That’s one of the biggest problems of evopsych: basically all theories are post-hoc. That’s not science, it’s wild speculation with a bunch of unfalsifiable claims.
Are you seriously comparing the breeding of crops with the human genome? Analysing the human genome is not the same as eugenics with a less burned name. The whole idea of eugenics is to make the human gene pool more shallow in favour of more “advantageous” traits/genes.and that doesn’t work, no matter how well the human genome is understood.
Also: nobody mentioned game theory or behavioral ecology, but you. Adting as if they were ever under attack by this video is mansplaining an best and strawmanning at worst.
Those are quite closely related branches of research. If you deal with one, you’re almost certainly also involved with another, so much that teaching them on the same course makes sense. Human psychology is considerably more complex than animal psychology, but built of the same blocks - and both humans and animals can, to different degrees, be rational agents in natural or artificial games, where their choice of strategy depends on their psychological profile.
Here are some articles on the subject. The deepest-drilling article is not about humans, but dogs.
“Genetic mapping of canine fear and aggression”
So it seems that in dogs, there likely is a genetic factor involved in fear of unfamiliar individuals and agression towards them. It is no wonder, as countless generations of wolves have likely needed to decide how to relate to an individual from another pack, and this has sometimes conveyed them advantages or disadvantages.
Large Study Identifies Genetic Variants Linked to Risk Tolerance and Risky Behaviors
So it seems that in humans, there are hundreds (or thousands) of genes subtly influencing different types of risk-and-reward calculations. Trust (or distrust) in strangers is a narrower part of a wider array of attributes which can be summarized as “risk tolerance”. It has been noticed recently that genetic factors contribute, along with environmental factors, of course. It is worth noting that genetic factors aren’t considered to be the biggest source of influence.
…and in practise, a person knowing about their genetic predisposition might apply this knowledge in related fields - e.g. when negotiating a risky deal, deciding whether to litigate or take retribution after being wronged, deciding whether to wear a life vest or attach a seatbelt.
Some person might know of their predisposition to seeking higher reward at high risk, and refrain from gambling. Another might know that their reward-seeking mechanisms are more susceptible than usual to chemical addiction, and avoid consuming certain substances. Another might know of their predisposition to averting loss, even if it also averts gain, and deliberately increase their willingness to take business risk. Another might want to compensate against their higher tendency to distrust strangers, or against a tendency to trust too easily.
Yes. All life on Earth is related. Even plants and bacteria use the same sort of ribosomes to make their protein, and most air-breathers use the same sort of mitochondria to process oxygen. Altering plants so they would resist drought or flooding better is only some degree of knowledge away from giving oneself or others night vision, ability to heal bigger wounds, greater resistance to cancer or inability to get thrombosis.
Not hastily, though, as genomes don’t have their goods in clearly labeled boxes.
I stand by my statement that you are one of the people who would have learned the most from the video.
Alas, I did not have the time to watch it all.
