Weaker signal, more noise - the dilemma(s) of the highly selective college in the current age

After reaching a certain threshold of high school academic “stats” that are predictive of academic success at the a selective college, adcoms are looking at: 1) Is the student going to “add to our college”, either demographically (they are the only student from Idaho applying) and / or once they get on campus by being involved in activities that publicize the college in a positive light 2) After they graduate are they likely to keep furthering the college through success, testimony, & monetary contribution.
