I was reading reviews of HPMOR on Goodreads and I noticed that the people who didn't like the book were essentially "put off by the rationality". They thought Harry was arrogant and condescending.

Then I was thinking, a lot of people are "put off by rationality" for similar reasons. What a shame. There's a lot of value in spreading rationality, and this seems to be a big obstacle in doing so.

Any thoughts on how to make people less "put off by rationality"? I think the core issues are:

1. In some cases, people think it's rude to suggest to someone that they're wrong. (I have a vague idea of when, but am having trouble articulating it. Can anyone articulate this well?). Edit: EY has articulated (part?) of what I'm getting at. He calls it the status slapdown emotion.
2. People pattern-match the tone to "smart aleck"?
