The Latest On Intelligence

I never knew it was the "Murray Gell-Mann Amnesia effect" but I've been using this exact line of reasoning for many years when discussing the validity of stories read and watched in the media. Interestingly I discovered it as a kid reading a newspaper article about video games something I was very much into at the time. The were talking about the Sega Genesis and the Super Nintendo and at least half of the article's "facts" were just flat wrong and many of the opinions were far left field of what a legitimate gamer would really think. That's when I made the connection. If this story which is something that I am intimately familiar is so utterly wrong then...what about the things I don't know about. That was about the time I stopped paying so much attention to the general media.

I didn't know it had a fancy name though.

You're not alone. I've always wondered, how come different dog breeds have different behavior and intelligence levels. Yet certain breeds are much smarter than others and capable of greater learning capacity. Any kind of comparison, even scientific, between human races would be seen as racist and thrown out immediately. It conjures up all sorts of negative emotions. Hitler, Nazis, Eugenics, Master Races, Holocausts.

I think deep down inside we are slaves to our genetics and many people know so and have significant evidence for it but are keeping quiet. And I don't blame them. The repercussions of telling the human race "Your success, happiness, intelligence, health, and entire life is limited by your genetics." would be horrific. Half the world would be on anti-depression medications if you told them that and proved it. No one wants to be told who they are before they're given a chance to discover themselves on their own. Also, genetics are not the end all of success. Just because someone doesn't have the genes that make them more likely to be successful doesn't mean they'll never be successful. There are other ways around. Aggression, luck, money, hard work, etc....

For instance, Ashkenazi Jews have the highest intelligence and very poor Spatial intelligence according to research. After them come north east Asians. Jews are disproportionately successful in numerous fields. 25% of Nobel prize winners are jewish and this is increasing. All of the major Hollywood studios were started by jews and are currently dominated by jews. The NYT's Joel Stein could only find 5 non-jewish executives in all of Hollywood. Most of the top writers are also jewish. Banking and finance is dominated by them as well. So is the fashion industry: Marc Jacobs, Ralph Lauren, Marc Echo, Calvin Klein, Estée Lauder, Kenneth Cole, and others are jewish. Levi's jeans as well. 2 of the internet's biggest companies, Google and Facebook were started by jews Larry Page, Sergey Brin, Mark Zuckerberg. People's refusal to acknowledge that genetics has anything to do with intelligence is exactly what has sprouted numerous conspiracy theories to try to explain why jews are so well achieved.

Also, look at men vs women. How many wars have women started compared to men? Nearly every war, genocide, and conflict has been caused entirely by men. Why is it that we never see the female versions of Hitler, Gangis Kahn, Napoleon, Stalin, etc... Because evolution has created extremely violent men (not all of us of course). Evolution wise, we're disposable. Women are not. The human race can easily be replenished with 99 women and 1 man. But not with 99 men and 1 women. And so women live much more "slow but steady" lifestyles while men are more likely to live "risky" lifestyles. Rewards are proportionate to risk. So men reap the rewards when it comes to inventions, companies, religions, nation building, etc...

[To gwern, unprovoked] You are attempting the early dismissal of some viewpoint you disagree with on a more or less political grounds but this has not very much to do with science.

[Next reply] Why can't the critique proceed on a higher level than "those Xists are deliberately lying again"?

You seem to be suffering from some cognitive dissonance here.

Oh, this wasn't a jab at you. Rather, that's the part of grandparent's post that I think is the most concerning. I just don't have the knowledge and skills to see if it's true, so I was asking you.

Usually, part of the science process is to analyze results in the context of similar work. If the authors are indeed cherry-picking and ignoring counter-results instead of acknowledging them, then that's bad.

The squirrel example is absolutely absurd - there are clear physiological, morphological differences between human beings and squirrels that influence whether or not squirrels even have the capacity to master fire, or whatever other silly comparison you choose. Furthermore, I think you will find that environmental factors plainly influence the behavior of animal populations (squirrels, chimpanzees, birds - any kingdom, genus or species you choose) far more than any particular genetic variation among them - animals of the same species without abundant resources behave quite differently from animals of the same species in an environment of abundance (one need only look at any pest species - animal or plant - to see that this is true).

There does not exist much variation across 'societies' of animals within the same species - one tribe of baboons is much like another tribe - but there exist vast gaps between societies of human beings, so far as these gaps influence the environment of individuals among populations, and entire populations as a whole.

There is no physiological model for human intelligence, and since only physiological traits are inheritable (though psychological traits may be derived from morphological differences) there is no model for genetic influence on intelligence. Since there is no model, you can only blindly test a black-box hypothesis - and the results from those tests appear to support the conclusion that there does not exist any inheritable, physiological difference that would influence intelligence, controlling for societal factors.
