Our gut reactions tend to perceive "the public" as a whole as sharing our perspective. This problem is especially problematic when it causes us to overrate substantially the extent to which others will agree with our political opinions.
So why do we give ourselves a pass, while attributing an obnoxious status to others? Why does our gut always make us out to be the good guys, and other people bad guys? Clearly, there is a disconnect between our gut reaction and reality here.
