Issues of measuring ideological sophistication: Level of conceptualization,attitudinal consistency,and attitudinal stability

This study uses the CPS 1972–1976 election panel to examine the construct validity of three traditional measures of belief system sophistication: level of conceptualization, attitudinal consistency, and attitudinal stability. The analysis reveals that these measures tap two distinct characteristics that are virtually unrelated to one another. As expected, level of conceptualization proves to be a valid but modestly reliable indicator of ideological sophistication. However, the consistency and stability measures are found to tap a structural or configurational property of belief systems that apparently has nothing to do with ideological sophistication. These findings strongly recommend against the use of attitudinal consistency and stability measures in future studies of political sophistication. They also call for a major reappraisal of prior attitudinal consistency and stability research.This is a revised version of a paper delivered at the Annual Meeting of the American Political Science Association, 1985, New Orleans.
