I think your first line is a great generic response and sufficient in itself: Our process has a high chance of providing false negatives, so just because we are not offering you a position doesn't mean we are convinced you are not qualified. I don't really care for the reason why I'm rejected. I'm deluded enough in my own abilities to rationalize the reasons why you're making a huge mistake. :) The main thing I want is a timely response. What drives me crazy is not getting any response at all.
