I'm currently about to submit my first application, but I'm not sure how to answer this question.

The school in question is pretty middle-of-the-road for me (not a reach or a safety). As of right now, the list of schools I'm applying to is not 100% set in stone. If I end up deciding to apply to a school that I do not include in my answer to this question, is there anyway the school would find out and think I was lying to them?

Furthermore, if this question is on an application for a safety school, should I just leave it blank? I've read some things that say schools might strike you down if you list higher ranked schools than theirs and your numbers are competitive, for yield purposes.

Am I just overthinking this? Should I just list the schools I am applying to as of right now? Should I just leave it blank (it is not a mandatory question)?
