What do you believe because others believe it, even though your own evidence and reasoning ("impressions") point the other way?

I don't know. If I did, I'd probably try to do something about it. But my subconscious mind seems to have prevented me from noticing examples. I don't doubt that they exist, lurking behind the blind spot of self-delusion. But I can't name a single one.
