Trying to determine the cause of racial differences in IQ is extremely complicated, since we cannot simply assign a person Black genes and a White environment while growing up (since having black skin in itself will mean a person's environment while growing up is different). I'd be very interested in seeing a specific study, but to my knowledge there is no compelling evidence for either nature or nurture when it comes to racial IQ differences. There have been a lot of studies with varying results. But the narratives that "people went looking for differences because of their racial biases, but then their studies were debunked" is not accurate. The fact that people believe this narrative is due to politics. For example, Steven J Gould "debunked" craniometry in "The Mismeasure of Man". But his debunking was criticized by peer reviewed work that upheld the original craniometry work[0].
