A major argument in Adam Rutherford's book + the culture generally is that the races have been in gene-flow contact throughout history and that this somehow means that major differences can't arise.

The thing is, speciation is possible in the presence of gene flow:
https://sci-hub.ru/https://doi.org/10.1016/j.tree.2005.02.010

These things are a matter of degree. It of course makes sense that this is the case, as even if the boundary between two gene pools is merely clinal, the two gene pools can still be different enough on net that said differences between gene pools have to be taken into when 'deciding' if a new allele is adaptive in one or the other. When this sort of gene-gene interaction structure starts to develop, this can make a difference between groups which was once purely clinal stop being so.

People like Rutherford who think that gene flow has something to do with the plausibility of group differences are also more right than they know; as it turns out, countries with larger genetic distances tend to have larger absolute IQ gaps:
https://www.sciencedirect.com/science/article/abs/pii/S019188691630174X

Now how continuous are the human group differences?
A) Although genetic distance increases with geographic distance, genetic distances between genetic clusters are larger than what would be predicted from the geographic distances between the clusters:
https://sci-hub.ru/https://doi.org/10.1371/journal.pgen.0010070
B) This of course makes sense gives that the boundaries between groups tend to align with geographic barriers like mountains + deserts + bodies of water + etc:

"Our studies demonstrate that many psychology researchers overestimate the evidence in favor of a theory if one or more results from a set of replication studies are statistically significant, highlighting the need for better statistical education."

How do psychology researchers interpret the results of multiple replication studies?
