Comment Harvard tried a different approach long before (Score 1) 529
Malcom Gladwell wrote about this identical issue in the New Yorker (http://www.newyorker.com/magazine/2005/10/10/getting-in). The concepts applied especially to Jews, and to all the Ivy-League institutions. The problem the Ivys were addressing was that if they based their admissions criteria on grades and test scores alone, Harvard would be nearly all Jewish and Asian. But those students, even with their high scores, would not achieve in life any better, or even as well, as students selected in part based on subjective traits such as "manliness." The Ivys have perfected a system that identifies future high contributors to society, and convinces them to enroll at their institutions. That is one explanation of why if you are admitted to Harvard, it makes no difference to your future success whether you enroll: You have been identified as a future high achiever.
