You try a rebuttal, which I commend, but the approach of your rebuttal isn't strong enough! Height also correlates with "basically every good life outcome" but the application form didn't ask for our height: nor should it.

IQ is inherently different. I really support the IQ test they decided to give and I definitely think they should glance at the results - especially to basically approve any applications from people with great results even if the evaluators don't understand the proposed application exactly.
