Research Looks at Perceptions of Political Parties



According to new research by Assistant Professor of Political Science Douglas J. Ahler and his colleague, data scientist Gaurav Sood, Americans show significant bias in how they perceive political parties. Ahler and Sood asked 1,000 Americans to guess what percentage of each party is made up of groups stereotypically associated with that party. In every category, the respondents overestimated the actual numbers, often by significant margins.


As the chart above shows, the respondents were slightly more accurate when making guesses about their own party. But only slightly. Which shows our assumptions about our own parties aren’t much better than our assumptions about the other party.

Perhaps more surprising, the respondents who reported tracking politics MORE CLOSELY, were LESS ACCURATE in their guesses. The research does not tackle the reasons behind this negative correlation, but it raises fascinating questions about the information reaching the electorate through advertising, traditional media and other online sources.

Bottom line, according to this study, we shouldn’t assume we know who makes up the other party. As Sood put it, “What we know about the American polity is that they don’t actually pay a ton of attention to politics, but they seem to have these deeply-prejudicial views about the other side. And what we are telling you is that what you may know… ain’t so right.”
