I think you'll find MIT's gatekeeping is extensively systematized. : ) Which is not to say that MIT admissions don't sometimes revolve around human elements, and moreso the process of landing RA positions, but the sheer number of people gunning for these opportunities its its own kind of gatekeeping. These human factors, the networking and outreach and so forth that goes into "surfacing opportunities," are fiercely pursued now, to the point that it becomes another hoop to jump through even past the grades and SATs and internships that we think of as the "system." One can certainly learn to play the game, but it'd be awfully nice if we didn't have to.
