Ivy Adcoms Still Promoting--why??

<p>I have another thought:
Do you think these elite colleges believe it is important to have proof of very aggressive and broad and de facto imprecise outreach activities (till the last minute!) to defend themselves (legally; image-wise) against (potential) accusations of discrimination, i.e. pre-selection and preference for certain types/populations and disinterest in other types/populations of applicants?</p>
