“Jews”, “nigerians”, “whites”, “blacks”, please provide relevant backgroundies like social class, ethnicity, locality etc of studied people. More additional aspects enrich the research.

So expecting massive creative achievements by african blacks in UK. Missing “evidences’ from other european and non european countries like France about black africans outperforming scholastically and in outschool tasks.

Regression to the mean literally only happens to familial or gene-local level. Regression to the racial or broad group-level mean is a statistical coincidence, not a literal tendency.

Britain is historically very stratified socially indeed.

You forgot to say that Harvard is mostly djooisch these days. I think you are right about on avg east asian lower creativity (these days) namely continental ones because japanese tend to exccel on it, not in pair with whitey but.
But the truth is in the middle. Harvard apply supposedly a “pure meritocratic examination” to select their puppyles but there are lot of money (and jewethnic nepotism) involved in this process that make it significantly less meritocratic despite the fact that the university as well other ivy ones doesn’t analyse creative potential (make even less merit based).

Maybe africans “are” great on capital’s names memorizing?? I used to be good on it.

Contradiction alert about factor g: being good at something often means being equally to similarly good to other things.

So if “africans” are so great cognitively based exclusively on scrabble game why they are not great on chess game, “equally cognitive demanding”?? This very good scrabble gamers are generally smarter on other fields??

I believe Black african race has evolved to be more verbally smart based on very good oral or communicational verbal skills. Seems blacks tend to have faster communicational reasoning despite having on avg lower IQ. I believe the same happen with gypsies and the historically more verbal-evolved ashkenazis. It’s possibly explain this “anomaly”.
