Bryan swats Tyler

Tyler might as well stand up at a concert to "prove" that everyone at the concert will see better if everyone stands up.

Arnold piles on, sounding quite sensible to me:
My guess is that if you add up the cost of doing all of the studies in the education/earnings literature, it is far more than the cost would have been of undertaking a college scholarship lottery among a sample of students and observing the differences in outcomes. To study the relevant margin, choose the sample of students from those whose grades and SAT scores would barely gain them admission to second-tier state schools. Randomly give half of them full-ride scholarships and give half of them nothing. Observe their years of schooling and their subsequent earnings. Base your conclusion on those results.
