19. Aggression III

(May 14, 2010) Robert Sapolsky continues his neurobiological exploration of human aggression. He discusses correlations between neurotransmitter prevalence and aggression levels, aggressive activity differences from genetic variance, societal factors and application, amplification from alcohol, and crime and punishment.

Such a great finale in the last 10 mns. The effective morality does not come so much from declarative memory, from the cortex and all that has been learnt and acquired during development and adulthood. It comes mostly from implicit memory, what has been acquired in younger age and become quasi-instinctive and nearly automatic, from the cerebellum. And then, out of the blue, the amazing question "What day is it?"

[@Rawi888]

Anyone notice how Sapolsky never “um”s or “ah”s? He is either solely a highly cerebral speaker, or that, and he practices his lectures loads, which just makes him more admirable as a lecturer.

[@1LoveSol]

Umms and Ahhs mean that the person is accessing a higher field of knowledge. Its not some sign of genius that you can talk withought a pause.

[@ElektrykFlaaj]

or it just means that he knows what he is talking about very well

[@Gillsing]

Presumably he knows what he's going to say because he's already said it many times before in previous lectures. I'm getting the impression that he's got a lot to say and is trying to fit as much as possible into whatever time he's got before class is over. Not slowed down at all.

[@Dfd_Free_Speech]

There is quite a lot of stuff outdated already. Particularly in regards of psychology/behavior Sapolsky quotes lots of claims that failed to replicate in bigger studies, and generally recent scientific studies show that the genes that you inherit from your parents play a much bigger role than how you are raised by them. In other words: genes >> shared environment.

I would argue that aggression is a very important part of us but we have to learn how to own it. Directly approaching people one might be romantically or platonically interested in already holds a little bit of aggression in it. But as I mentioned it is a skill one needs to master in order for it not randomly finding venting spots as in soccer games where the fans turn violent. Great lectures though. It has been a blast so far.

[@emmar9104]

I've always thought that unusually heroic behavior was linked to aspergers or low social awareness, using reasoning from my own experiences as an aspergers kid: When I was a kid I would actively step into cases of bullying, even though I didnt know the kid being bullied. When I looked at bullying, I felt upset: Yes, I was disturbed that it felt bad for the victim, but mostly I had this strong feeling that the bully is breaking the moral code. What I told them when I interrupted the bullying was something along the lines of "You're not supposed to do that. How can you do that. It's such an ugly thing to do. I can't fathom how you derive joy from doing such an ugly thing." Which I truly didn't understand. When I was an even smaller kid, younger than I can recall, I was with my dad and we witnessed the people in a parked car toss their ice cream wrappers out the window. I got up, picked up the wrappers, and threw them back inside. My dad wasnt sure of my reasoning, and I sure as hell dont remember what I was thinking. But that, along with my later experiences, make me thinkg that my seemingly "brave" actions was me actually breaking moral code- not caring what others were thinking, not doing the socially sophisticated move of "keeping tabs" on how much effort everyone else was putting in. I was playing the social game as good as I could: according to rigid, simple rules. It's become intuition now, and for instance when I walk through a weighted public door, I'll always check if there's someone behind me who's walking a bike, and if they are, I'll always stay and hold it - because it's THAT cumbersome to try to puch it open while you're also holding your bike. No one told me to do it, it just makes sense if you do the utility math. Most others dont, and though it makes me angry, I think I'll keep doing it. I guess this is different though. It's not unusually heroic. I doubt I would do something truly heroic.

[@SameAsAnyOtherStranger]

The heroic are less likely to pass on their genes. On account of the death inducing consequences being heroic can cause.

These lectures are fantastic! His mastery of the subject and his amazing recall of so many previous experimental studies including the lead scientists of such studies is no small feat. Also, here's a guy who's spent much time in the field, studying wild Baboons. He "Walks the Walk"; as opposed to merely "Talking the Talk". Brilliant guy, who is a wonderful lecturer. One of a kind! I am so grateful that these lectures are free on KZbin.

[@awhodothey]

There's no correlation between absolute poverty and aggression. The correlation is between relative poverty and aggression, and even that is contingent upon social acceptance of the aggression. I'm surprised he didn't even mention Gini coefficients.

[@fionafiona1146]

There is a link between resource access and development, including in such circumstances where malnutrition is not a sing of poverty (1930s Japanese soldiers getting scorbut from eating white (fancy) rice but little else (unlike poor or very rich people)).

[@FatViky]

I think it would be stress. Stress is the what causes this effect in the brain, of agression. Extended families living in poverty but supporting and helping each other or having human resource to compensate would probably not cause this agression.

By assessing whether behaviour such as bullying/hurting smaller children and animals existed in these children, and to what degree, prior to whatever stage/effect they are studying. There's more, of course. Paediatric psychopathology is a frightening thing to study.

[@Arzamol5]

@@benoplustee Yeah, he always makes sure to point out the prominent conflicting theories and arguments that have been made about the subject. It's all interesting, I guess I'm just wondering how things have progressed in general since then, and if any of this info has been expanded on or debunked. It'd be interesting to see what's different about his lectures today.

[@benoplustee]

@@Arzamol5 I'm curious too! However I think the topics covered in this course are so broad and diverse that I'd be surprised if 10 years was enough for a dramatic/seismic shift in the bulk of these theories that -wouldnt- have trickled down into the lay press to some degree. Could be wrong tho!

Fascinating bit about Roe vs. Wade driving down crime rates. And rather poignant given its recent repeal.

Yeah...the "Freakanomics" take is severely lacking. Another viable contender as the causality of that drop in crime is the decreased exposure to lead in the environment- making gasoline unleaded, making paint lead free and the general recognition of lead as a neurotoxin

also---turns out to be unfounded. Birth rates haven't declined since Roe v Wade in a magnitude that would explain the crime rate drop.
