East Asians are "impaired" the least, and the presumption among Western scientists, particularly American scientists regarding Asian Americans, is that they are simply undiagnosed despite their out performance in nearly every metric of success.
I'm sure it must have nothing at all to do with cultural stigma. If that were true we'd see signs of mental struggles in their home countries. In the US I'm sure all the model minority bullshit people project on them doesn't cause them any extra pressure or anxiety right?
Asian Americans are so successful that they certainly must not have disproportionately higher rates of suicide right? That might be a sign of some "impairment" going unaddressed! Or maybe you see the rate at which they're killing themselves as yet another metric of success? Those scrappy East Asians are just so good at doing stuff!
Asian Americans and East Asians have lower suicide rates than Americans (over 60% lower), and especially American white males, you've fallen for a false trope, which is exactly what I expected when I posed the question. I knew that you would immediately appeal to this false trope because you're looking for an excuse.
They outperform by the metrics that matter for a clinical diagnosis and the West is so quick to jump to the conclusion that they're "under diagnosed", it's a uniquely Western and especially American conclusion.
Why do you think that is?
