Sure. I did not say "almost anything." I said "socially valued traits**." Group diffs in sickle cell? Some hormone? Hypertension? Proneness to cancer? Heart disease? Def do not include any of that. **In the psych sense.

What prior probability do people who want to ban research on population differences in socially valued traits assign to the existence of such differences? It must be high enough that they fear it won't debunk those "racial theories." I believe it's >0.05.https://axisofordinary.tumblr.com/post/186584192813/can-we-rule-out-genetically-determined-cognitive …

Moratorium≠ban. Also, study group diffs galore. In other species to show you know what you are doing. If you can't show you know what you are doing with other species, there is no reason for any of us to have any confidence you know what you are doing w/humans.

I am skeptical of this. Other species are not cultural species to the extreme degree humans are. So group heritabilities are less direct in humans, and results from animal studies can not be assumed necessarily valid in humans also.

Right, my point was not generalizability, it was tractability and soundness of the methods. If we can't do it when things are simpler, I'd be very dubious about adding complexity.

It doesn't really seem to me that such studies would help at all really. We already know that behavior differences between animal species / breeds are genetic. Perhaps you could help with an example of a hypothetical study?

Not my field, plus its probably hard; I have little doubt it could be done (tho that's easy for me to say, not doing it). Develop a method for studying intelligence in other mammals like this. 1/n ending in END.pic.twitter.com/DpTgHDqERa

Then create strains of mice w/greater v. lesser intelligence. Heavily manip the environ to see how much one can undermine iq of smart mice, increase it among dumb mice.

Let's assume that we do this succesfully. (A very safe assumption, given that there are difference in intelligence between animal species, and experiments like this https://en.wikipedia.org/wiki/Domesticated_red_fox ….) Then what? What does this tell us about humans, or about studying humans?

Very little. But if there is widespread consensus that such methods work w/a variety of other species, it tells us that our methods have been well-validated enough to begin considering the possibility of using them with humans. Minimal necessary condition, imho.

We have bred smarter rats, fish and probably others already. https://en.wikipedia.org/wiki/Tryon's_Rat_Experiment …https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3566478/ …

Humans have bred animals for millenia without any equivalent to the modern understanding of evolution, genetics, or heritability. It does not help solve the problem of sources of intact group diffs.
