Not trying to nitpick....but 10 IQ points is less than a standard deviation so any increase or decrease by that much isn't super significant (and is expected). In regards to everything else, tl;dr.

This was studied deeply by individuals like Jason Richwine. A far deeping understanding than you have. IQ is 15% upbribging and 85% genetic. If you study your balls off you can still fall 85% short.

It can be a useful indicator, but it's still not a great indicator. We're talking about the social sciences here, where a p value of 0.6 is acceptable.

Honestly any university textbook will get you started and give you further resources.

You mean how you take the word of a political commentator on an academic subject?

I agree, that's pretty dumb.

I did a bit of reading on Jason Richwine.

He doesn't make statements nearly as strong as what you posted as far as I can tell.

You just did what the media loves to do. Take tempered statements from scientists and blow them out of proportion. (it appears)



Still strange that he works at the Heritage foundation, so I'm sure I'm missing some piece of the puzzle on what he's written. You don't get a job there by being an unbiased professional....

Notably your brain.

what many people dont seem to understand is this: the intellectual ceiling of a person is heavily influenced by his or her genes, yes. but to reach one's potential requires good nutrition, an intellectually stimulating environment while growing up, good education and so on. IQ tests measure a proxy quantity for the intellectual capabilities of someone, not their potential ceiling. so if, for example, a significantly higher percentage of minorities than of whites live in poverty, then those minorities will, on average, stay farther below their intellectual potential than whites. therefore, IQ differences between ethnicities coupled with a genetic contribution to intellect still dont necessarily imply that people of color are born intellectually inferior or anything like that.

yes, it is imaginable that there are really differences between ethnicities on a genetic level with respect to intellect, but if such differences exist, their influence will most likely be smaller than the "environment" aspect. and there are other aspects too, like higher IQ people being more successful on average, and successul and/or smart people tending to mate with each other instead of with poor/stupid folks. this "social selection" effect certainly also plays into it and over time increases spreads in measured IQ.
