This is grim because there's nowhere to go.
The US spends more on research and development than any other country in the world (by far), and we have more PI-level positions than anywhere else (by far).

If true, this is unbelievable.
Ruling out the investigation of biases means destroying a wide variety of computational social science-, anthropological and psychological research science but also key research on AI and safety.
This is highly dangerous for science.
