Judging competitiveness by the amount of spots unfilled has serious flaws.
First of all, is it that surgery is more competitive, or that PD's simply ranked more people per position in order to fill? Or is the applicant pool being filled in by more applicants with lower scores? Or is it some combination of the above?
While I know that a lot of GS applicants are very strong, the average applicant is certainly not on the level of the average ENT, Uro, Derm, Plastics applicant...
I think that interest in surgery has certainly increased, which will make it a bit more competitive. But, I also think that GS is still a far, far easier match than some of the traditionally competitive programs.
I mean, look at my field, Ob/Gyn. It certainly went up in competitiveness based on percentage unfilled. In fact, by this criteria ob is more competitive than Gas, Rads, and EM this year, to name a few. But, do you really think the average ob applicant is a more competitive applicant than the average rads applicant?
There are simply too many factors to make a claim like this. And, given the realtively HUGE amount of positions in GS, there is certainly still room for the average applicant somewhere.
