Sex Differences in Attitude Expression: A Generational Explanation

Abstract

Females have consistently shown higher DK response rates than males in surveys. Using the 1972 Center for Political Studies National Election Study, this sex difference is shown to be a largely generational phenomenon which is much greater among older than younger respondents. It also declines at higher levels of political knowledge and interest. Finally, using the CPS 1972–76 national panel, DK response rate shows high test-retest reliability.
