Unlike what the general audience believes in this thread, I think
@GaiusOctavius brings up a good point, albeit misguidedly.
The current hypothetical guy does sound like he has an ego for blatantly ignoring instructions and feeling entitled to a med school spot, which are deplorable traits no med school should want. Reject, sure, blah blah.
BUT I think the more general question is very valid: how do we tell what is forced BS that is cooked for apps versus true writing, and does it matter? Obviously, true voices are easily spotted, but NO WAY IN HELL can all the fakers be spotted. So if an applicant has a one- or two-liner reason about why medicine and writes only that, would that be frowned upon? Is there a unilateral requirement for a PS to be of a certain length of elaboration, if the situation was simple enough to explain in 2 paragraphs? Would an applicant be rejected for writing something so short and simple just because it looks like he's being lazy by not wanting to write a lengthy PS which we know adcoms don't even consider all that important for most people anyway? Do adcoms just want people to follow instructions for the sake of following instructions, if the purpose of the PS can still be satisfied?
That's what I'd like to know.
