When this is tried, it does not output ideologically-pleasing student demographics. Presumably because all objective tests of merit are hopelessly biased.

Caltech is such a school. And its population is largely largely Asian and Jewish, both demographics Harvard has a history of discriminating against.

I am sure Caltech’s administration is considered hopelessly reactionary, but their graduates have the highest number of Nobel prizes per capita. But again, what sort of merit does a Nobel prize prove? Look at the demographics of the winners.
