I haven't been through a residency interview process, so I'm speaking purely from logic rather than experience. Please correct me if I'm wrong on any of this. Don't the programs interview a lot of prospective residents prior to narrowing down their acceptances, just like dental school? So theoretically, wouldn't they also have backup interviewees to contact if someone were to drop out, again, just like dental school? Also, according to the logic that switching programs is selfish and inconsiderate in that it takes a spot from a peer, I feel like that same argument would then have to apply to dental students for switching programs after an initial acceptance. I don't know about you, but I had no shame in rescinding my initial dental acceptance to attend another school that better fit my goals and situation. Last, I would hardly use the word scrambling to describe the 5 months a program would have to fill that spot.
