I made the distinction in my post. Celebs are newsworthy before they even applied. But even celebs have to be able to handle the work once admitted. I personally doubt that Yale or any of its peers would accept a Kardashian Kid solely based upon celebrity.
The Wade brothers may have been locally newsworthy at birth in their hometown, but the national attention came only after their acceptances. Whether Yale would have only accepted 2 or 3 based upon their application and URM hook and chose to take them all so as not to split them up is something only a Yale AO would know. Maybe they did. Maybe not. Perhaps some people are just more cynical than me.
