Do we have evidence that whites and non-whites have different average levels of certain neurotransmitters? Are there actual gross physiological differences in white and non-write brains? If so, then there is more than just social-construction at work. If not, then social-construction is all there is.
Well we certainly have evidence that they behave differently. I don’t know about neurotransmitters (I’m guessing the experiment hasn’t been performed, imagine trying to get approval for it), also I don’t see why the exact details of the causal mechanism matter here.
The experiments have been performed. For instance, this dopamine receptor has a single nucleotide polymorphism that emerged in the middle east 40000 years ago (and therefore has very different prevalence across ethnic groups) and causes ADHD. There is a just-so evolutionary argument that states that as humanity spread out from Africa, novelty-seeking becomes advantageous as people adapt to new environments. This novelty-seeking is then pathologised as ADHD in the modern world.

Because they could allow us to predict which kinds of interventions would have which effects.
