American IQ scores have rapidly dropped, proving the 'Reverse Flynn effect'

Studying human athletic performance was also done by some eugenics movements, so by your logic we should stop all studies of human athletic performance?

You’re right, you got me. I can’t think of anything which modern intelligence researchers are proposing but sport scientists aren’t. No policy proposals or claims about say a general athletic factor which the elite class has but the impoverished doesn’t, or anything like that. These things are entirely equivalent /s
