Partisan and ideological belief systems: Do they differ?

In this paper a direct comparison is made between the cognitive content of ideological and partisan belief systems. A quasi-experimental design was used in a two-part study. Subjects were randomly assigned to either a partisan or ideological condition and asked to categorize and then scale contemporary leaders, groups, and issues as either Democrat or Republican, liberal or conservative. Results indicate that the meanings of partisan and ideological belief systems are quite similar — their cognitive attributes (issues, groups, and leaders) are interchangeable at the categorical level and highly correlated (r=0.86) in their degree of typicality. Political sophistication is determined to contribute significantly to the degree to which partisan and ideological belief systems are related. For politically sophisticated subjects (Ss) the two belief systems are highly related (r=0.90), whereas for low sophisticates, the belief systems are only moderately related (r=0.50). Sophistication also plays an important role in structuring Ss' own issue preferences. High sophisticates in both the liberal-conservative and Democratic-Republican conditions exhibit a greater level of issue constraint, which can be interpreted as either ideological or partisan constraint.Paper delivered at the Annual Meeting of the American Political Science Association, September 1983.
