It's compounded by a lot of things though.
There's evidence from every angle that supports it. Whether it's OK Cupid or "preference tests", empirical marriage data and surveys, the "eyeball test"...even...a highly trained Asian sociologist years ago around 2009 or 2010 from "Psychology Now" said that he had proven that BW were the "least desirable" and started an uproar.
Ok, stats like these almost always result in Black people not fairing well. And that includes BM being rated low. But it does not rule us.
"preference test" are no big of a deal IMO, considering everyone's going to prefer their features. And that's what some of those test are, features based
Ex: like one posted here on the coli a while ago, of BM/WM and results of what faces they preferred black or white
Spoiler: black men preferred black women faces, Cacs preferred Cac. Lol
Plus races are going to prefer even others that come close to theirs(skin color, hair etc). Our Black features are rather unique compared to other races and obviously some are not gonna favor our feats. As we are not gonna favor theirs. So you have that to consider
So yeah some stats may have some merit, but they also don't. Eye testing will show despite how many stats will say "you can't get anyone Nonblk" there are black men and women everyday with someone Nonblk people
Not defending or praising IR with nonblacks(I don't care what anyone does) just saying.
