There's a persistent myth that it's impossible to do science in this field and that people who try are cancelled. That's obviously false. You can just look this up. It's a fertile field and people are coming at it from multiple angles --- just watch arguments between behavioral and molecular geneticists on Twitter some time.

The people who actually are (/were) hounded are people like Richard Lynn, the godfather of "average IQ by country" data sets. That's because their data sets are fraudulent; not in a subtle way, but very directly: for instance, data for Sub-Saharan African countries are taken in many cases exclusively from mental health facilities, the only places IQ tests are done in any significant numbers in those places.
