I thought rationality was a measure of how one's actions are based on what you know, but not the things you don't know.
Prior to finding out that the NSA was wiretapping all the things, it might be considered irrational to expect them to intercept and store all of your information. Now that we know that, it would be irrational NOT to think that. The truth in both cases is the same: the NSA has been carbon copied on all of our packets for ages, the only difference is that now we know it's true (and not a "conspiracy theory").
