Abstract
The “level of conceptualization” index, introduced by Campbell et al. (1960), is commonly used to measure ideological awareness and sophistication among the electorate. Unfortunately, the validity and reliability of the original measure were never sufficiently examined. This article examines the level of conceptualization measures of Field and Anderson (1969) and Nie, Verba and Petrocik (1976). It reaches two major conclusions: (1) the measures under examination are neither reliable nor valid measures of the level of conceptualization construct; and (2) the measures reflect the rhetoric of contemporary political discourse rather than the actual process of political evaluation. These conclusions call into doubt the validity and reliability of the original measure of The American Voter.
