True-
If you are scrambling, where in the world will you find time to do research on a program unless you have had experience with the program-like if you interviewed there before, you did an elective there, etc. Time taken to research a program takes a good amount of time. So, while you are doing the research, another applicant got the spot.
Most likely, you will be selecting programs based on (1) geography (places close to home or what not) and if those programs are filled then you would probably apply to programs where (2) you could see yourself, but isn't your top choice...and if worse comes to worse, you'd might be applying to a program where you just (3) "want a spot", like Boondocks, USA.
So, if you are asked the "Why are you interested in our program?" question, what do programs expect out of applicants "scrambling for a position", who are just vying for a position (2,3 above), who have no experience with said program (which I think is true for a majority of those scrambling).
