What are some good counterarguments against the claim that the IQ differences between ethnic groups are mostly or entirely rooted in biology?

For a while now modern progressives have used a peculiar strategy: they simply deplatform problematic views instead of engaging them since engaging an idea in the first place is less effective at stopping it from spreading than silencing those who espouse it. That might be true but I'm a curious person who is deeply interested in why people believe what they believe. I wanted to find out whether the racists had a case. I easily found the writings of the smarter proponents of scientific racism. I have, however, not found many texts written by scientists on the other side, probably for the reason I mentioned at the beginning of this paragraph. Can you point me toward some?

Thus far the only well-backed short form essay I found is
