This has been on my mind lately since I saw the paper originally. I think the question for me is why people misestimate others' attitudes, and what that says about them. For instance, if a group of people are getting more liberal but believe everyone is getting more conservative, is that a reflection of their mood? I guess it raised a bunch of questions for me about how well surveys track things like mood and perceptions.
