What % of the Black-White IQ gap is due to genetic differences?
Please source your response.

Seriously though. Does anyone have a percentage estimate with some sound reasoning?

everyone is genetically different. define "race". also somebody please link that famous genetic clustering chart so i can get a good laugh

But of course once you have a low enough iq to strap into mr bone's race realist's wild ride, there's already no way off for you so no amount of evidence will change your mind

populations of people geographically separated that interbred and thus are genetically and physically distinguishable

There's genetic, but there's also nutrition/culture. African issue is primarily genetics. Asia/Whites issues is mix bag. Poor whites/Poor asians can have lower IQ simply due to lack of resources/nutrient rich food/etc.

There is no settled answer here. The best you can get is from a recent survey of expert opinions from intelligence researchers.

In Rushton & Jensen 2005, they suggest that default hypothesis should be 80% genetic, 20% environmental on the grounds that individual differences are explained by this model and that there is no reason to assume it's different between blacks and whites. You'd have to show that there are different sources of variance in one group or you'd have to treat both groups as subsets of the same population

There is no answer to this question as 'we' do not know nearly enough about genetics or the brain to answer it

>0%
Obvious cognitive dissonance. Anyone trying to argue intelligence has absolutely no heritability in 2020 is either intentionally ignoring obvious evidence or completely retarded themselves.
>50%
Most likely effect range based on twin studies, single nucleotide polymorphisms (yes, they do exist, not all intelligence is polygenic) and genome wide studies.
>80%
I highly doubt these people.

>Furthermore, while a 50-80% heritability is not definitive evidence for that the measured IQ gap between Blacks and Whites is 50-80% genetically caused, hereditarians have argued that this makes the 50-80% genetic explanation the most probable "default hypothesis".[8][9][76][77][7]

The 20% environmental factors that determines one's IQ could be the cause of 100% of the observed racial gap. Learn more about how heritability works.

That's an empirical question. You have to prove that's the case
