I don't think anyone has an objection to honestly studying heritable traits, including those for intelligence, but rather we object to how quickly people cherry-pick individual studies to support ideologies, without paying any heed to the general scientific consensus or other studies.

"This one study from 1976..." isn't a convincing case for establishing that link.

If there were a good meta-analysis that tied together several studies and made a reasonable, statistically-grounded case that race is tied to IQ, while simultaneously explaining the contradicting studies, the anime-avatar Race Realist crowd would be absolutely tripping over themselves to post it.

Where is it?
