Interesting, if potentially flawed:
We know that americans have become more biased against one another based on partisan affiliation over the past several decades. Most of us now discriminate against members of the other political side explicitly and implicitly—in hiring, dating, and marriage, as well as judgments of patriotism, compassion, and even physical attractiveness, according to recent research.
But we don’t know how this kind of stereotyping varies from place to place. Are there communities in America that are more or less politically forgiving than average? And if so, what can we learn from the outliers?
In general, the most politically intolerant Americans, according to the analysis, tend to be whiter, more highly educated, older, more urban, and more partisan themselves. This finding aligns in some ways with previous research by the University of Pennsylvania professor Diana Mutz, who has found that white, highly educated people are relatively isolated from political diversity. They don’t routinely talk with people who disagree with them; this isolation makes it easier for them to caricature their ideological opponents.
