In my defense, I have received zero aid from the program I am currently deferred from. Additionally, were I to apply and get accepted anywhere else (which I haven't done. I'm purely contemplating the idea), I would not pull a double-deposit stunt. I would of course forfeit my deferral deposit and inform the school I no longer planned to attend before accepting any other offer. That being said, it does make me nervous, because I remember from undergrad, it was really hammered into my head that if you accept or defer a position, you go, and to do anything else is unethical (which is totally true). It just makes me nervous, because even though I haven't seen anything specifically prohibiting it, the worst-case scenario is of course, that both schools somehow find out (I don't know if schools communicate with one another over things like this, for example), are affronted by the situation and both pull offers, especially considering that if there were really explicit rules concerning this sort of thing, it would make it much easier to know how to handle this situation. So it definitely requires some careful consideration and introspection about where I want to be and what would be best. Thanks so much for your input!
