I was gonna open a thread about it. I still can tbh.
The summary is: mixed race is doing SIGNIFICANTLY better than full blown ethnics and they are very close to whites in terms of dating success. BUT ONLY IF the other half is white.
black/asian mix doesnt do so good compared to hispanic/white mix for example.
I was kinda surprised that mixed people are seen almost as attractive as whites, so that blows up the one drop rule theory.
but on the other hand, studies show mixed men that are not half white aren't doing so good compared to half white mix.
so, according to studies conducted(Those I could find and read at least), one drop rule is a meme, being half white / half ethnic is almost as attractive as full whites.
