Maybe, but I don't see results that point to some races to be inferior to other in any sense. (TBH, I've read about genetic diversity in Africa, but it is it). I'm not looking for those reasons, because it is a stupid thing that doesn't matter really, but the point is: I don't see them. Therefore I don't believe to the field at large.

There continue to be published studies suggesting group differences in intelligence, but the weight of studies over the last 10 years or so seems to be in the other direction.

The explanation for that is probably the "missing heritability problem"; twin studies in the 1980s and 1990s set extraordinarily high heritability statistics for intelligence that have been undercut by molecular genetics results. Put differently: there was an unreasonably high correlation established in the literature at the turn of this century, and it's had nowhere to go but down.

(In case it matters for the thread: I'm not an expert, but I do follow this area of research, and I've been pretty convinced for many years now that supposed race/IQ correlations are basically bullshit, and that science is really beating the crap out of the old Murray and Lynn numbers.)
