Sorry I posted to your first question before I saw this comment.
Ooopps! That survey doesn't look confidential to ME! I think many on this board will agree that raising children in a JW environment is, to be polite, not the best and the survey in my opinion exposes as a weakness that other's can exploit. Not that they aren't working hard on it already.
The survey is completely confidential. If you individually feel uncomfortable, please don't participate. It's completely voluntary.
It is unethical to claim confidentiality where none exists. Universities (at least the universities with which I've been associated) don't tolerate misrepresentation of that type.
Please describe how this could be "exploited." Thank you.
