Hypothetically if the world's scientists were to all prove that blacks were inferior to whites, what good would come out of that? I can't think of a single good thing that would come from that- the world would be worse for knowing such a fact.
I'm pretty sure we have measured some very spicific things, and found that different races on average have some genetic advantages and disadvantages. Is saying that Asians are disadvantaged in milk drinking competitions making society worse? Also, because humans are diverse, differences between individuals within any racial group can be far greater than differences between races.
And if you compare men and women, the differences are much much bigger, and the comparisons much more frequent - you can barely turn on the TV or open up any social media without seeing them.
So, ultimately - so what?
