Youre probably right that this is the direction that med school admissions are going to head towards in the future, as more of the tech-savvy generation becomes older, established doctors that serve on these adcoms. But for right now, I dont think thats really the case, and Im basing that on two primary pieces of evidence: the fact that my mom (who works as an assistant dean at a New York hospital) has served on medical school admissions committees for several years, and my own experience serving as a student representative to a graduate admissions committee when I was in grad school. I can tell you that most committee members view their responsibilities to the adcom as a complete waste of their time. Dont forget, what they do while serving on the adcom is in addition to their other administrative duties, filling out paperwork, teaching classes, attending lectures, serving on other hospital committees, and everything else that keeps them away from seeing patients. Is it any wonder, then, that adcoms only meet once every 4-6 weeks at most schools? In order to really go over each and every application with the due diligence that you seem to ascribe to them would require them meeting far more often than that, don't you think? Do you really think the members are spending every waking hour in between their meetings going over 5000 applications with a fine tooth comb to find the 40 best? The answer is of course not.
And if you think about it in those terms, the whole process of med school admissions start to make a lot more sense. After all, is it any wonder that the first round of cuts are made solely on stats (GPA, MCAT, etc.)? The reason why is because its the easiest way to make the pile of applications smaller, and because it requires the least amount of effort on their part. Conversely, thats also why the cuts in the later stages (after the interview) always seem so arbitrary (in terms of why one candidate gets in versus another). It's because it IS arbitrary! At that point in the cycle there is very little difference between candidates, so they just pick their favorites using any metric that takes the least amount of time, even if its simply picking every fifth application in the pile. These guys are first and foremost doctors, who have already have a full-time job delivering medical care. Whatever they do on these committees is on top of that, so they are obviously going to make it as quick and painless for themselves as they possibly can. So I really can't see them tacking on hours of internet searching to the process if they feel they don't have to in order to make an admissions decision.
