Race and IQ: Genes That Predict Racial Intelligence Differences

[firemonkey]

Not as dumb as a nigger and not as mathematically skilled as an East-Asian..

Since when has mathematical skill been the sole measure of intelligence ?

Correct me if I'm wrong but, from my understanding and research of the phenomenon, regression to the mean is misconstrued by many psychometric analysts because:

1) It measures the IQ of children with either one higher than average IQ parent (who marries back into the average IQ gene pool)

or

2) abnormally high IQ parents whose lineage consists of average IQ ancestors.

Also, considering that children of exceptionally high IQ people from an average-low average population (Ashkenazi Jews compared to Southern Levantine pops. for example) tend to maintain their parents' intelligence, it doesn't make sense that it'd revert back to some arbitrary number. After all, that's how genes for intelligence get expressed more so in different populations from an ancestral base.

Looking it up fairly quickly I haven't read anything about the first point. All references I saw were of "both parents have an IQ of 160" or "the median of both parents IQ being 160", etc.

The argument against regression against the mean I have seen is that extended recent family/generations(of how many grandparents back I don't know) will be more important than the overall gene pool of the race or ethnicity in question, so hypothetically, if each next generation kept breeding with a same or higher IQ person, the regression to the mean would be slower, the mean IQ on the opposite side of the parents IQ would keep rising each generation and/or regression would eventually halt, or has already halted/has a higher mean than other families in the ethnic/racial group because they already selectively bred. Of course, you can't keep breeding within your family and to significantly slow regression could mean having to marry into another high IQ family, not just another high IQ individual.

Seems to me like that would take very selective breeding, and a long time, quite similar to the Ashkenazi process(Jewish in-group, high class preference). It's safe to assume if two successful, IQ 110 Igbo Nigerian-Americans(the average Nigerian number being 84) mate(for the sake of the argument, we can assume there are not established high IQ families yet in Nigeria, the two 110 IQ parents hit the lottery), their kid will have an IQ of 96-97. The kid will most likely breed with another person around 96, who also probably had parents not belonging to high IQ families, but high IQ individuals. Completely hypothetically, again for the sake of argument, let's raise the base IQ to 86(perhaps that's being too generous, again, I have no idea) after one generation, with more intelligence related SNP alleles now because of the four new added grandparents, that still puts the third generation at an IQ of 91. Seems like it would take a long time and the unlikely eugenics commitment. That assumes your first point is wrong, I don't know.

That is incorrect. It's 120 on average.

Medical school isn't here, but going off of Physiology, it does seem to be around 115(with Social Workers actually averaging around 100 and physicists averaging 130).



Btw, I'm probably a good example of my previous point. My mother studied Chemistry and I wound up studying something on the far left of that chart. x_x

Interesting, what did you study? My dad also studied something completely different than me. I was originally going to become a mechanical engineer, but got more interested in the health and cancer research field.

I've seen several studies and graphs that peg it at 110 for doctors actually. And the actual doctor IQ is not the same as the majors, because most of the doctors these days come from other countries. Mainly India and similar places that don't have nearly the same standards as american schools (which have also gone down a lot though).
