Two groups with IQ’s of 85 will probably behave about the same, right? Nope!
That is because we are leaving out something very important, and that is race. And race is absolutely real in a biological sense and you can make whatever you want of that. An 85 IQ US White, Persian in Iran, Chinese in China and US Black are going to act pretty different, though the American White and the Persian might act fairly similar. The races act different! I’m sorry but it’s just true. Open your eyes and ears. It’s only obvious.
A good IQ researcher over at Unz has written a number of articles where he claims that the IQ of your average human is ~81. That’s terrible. It’s thought that you need a 90 IQ to create a decent modern society. That’s probably not completely true, but there’s something to it.
It also depends on the population. An Arab, North African or Central Asian IQ of 85 is simply not the same thing as a US Black IQ of 85. Go look around in Arabia, North Africa or Iran and get back to me. Even Pakistan is fairly civilized.
If those countries were full of US Blacks, the cities would look like Detroit, Baltimore, Philadelphia, Chicago, Oakland, etc. That’s why I get so upset with White nationalists snarly at Blacks that they only have 85 IQ’s. First of all, it’s probably 87 now. Second of all, that IQ score is no fault of their own. It is some sort of a product of genes and environment. Let’s put it this way. I don’t think the US Black 87 IQ is their fault at all! That’s simply the way they end up getting wired up.
If Tehran and Detroit have the same average IQ, there is something more going on with US Blacks.
I believe that is psychopathy. Your average US Black has a psychopathy score twice as high as the average White on the PCL. Say the average White score is 4 out of 0-40. Everything below 20 is considered in normal range, but you can be quite psychopathic and still be in the normal range. What can I say? We are apex predators, meat eaters and killers of our own kind from time immemorial. He aren’t like cows. We are more like bears or mountain lions.
Anyway if your average US Black has a PCL score of 8 to the average US White score of 4, that is going to make a tremendous amount of difference. That’s because there is a universe of difference between a PCL score of 1 and one of 19! They’re both completely normal non-psychopaths, but I guarantee you that folks at 19 on a PCL are going to act way worse than people with a PCL of one.
Blacks also seem to have elevated testosterone levels, and that is absolutely genetic. But they are only higher until age 32, after which they fall and are actually lower than Whites! I suspect that elevated testosterone plays a role in the extremely high crime rates of US Blacks.
Let’s not get too hung up on IQ.
