You can do this with brains after people have died.
Likewise you can measure the inside of their skulls after death.
I don't know why you're trying to act like it's somehow impossible to measure or estimate brain volume - we've been able to do it for hundreds of years. Are you shitskins or something? White science is beyond your comprehension?

Basically only the top 25% of Pakistani and Black Caribbeans deserve to survive, the rest need to be culled. Donβt know how but we will have to do it, as it was done with the dumbest of our kind centuries ago. Maybe nukes will help, most probably it will be famine and epidemics

What's interesting about this graph is that it suggests that there's an optimal brain size and that you get dumber when it gets bigger.
