In the academy, it's not enough to be sensible: there is an expectation that you should have convincing reasons for your view and be aware of objections. If a student is trying to end up near where the instructor is, the instructor will notice if the student got there by a route the instructor thought about but rejected for being overly simplistic or worse.

I've also noticed this in my daily life. I wince when somebody I agree with at a high level gets horribly tripped up in the details. I assume it's because I want to believe that people who agree with me do so for good reasons.
