Partisan Expressive Responding: Lessons from Two Decades of Research

MATTHEW H. GRAHAM

Abstract

Research on partisan expressive responding suggests that the beliefs people express in surveys are more partisan than their underlying perceptions. This article examines the scope and importance of expressive responding through a meta-reanalysis of 44 studies from 25 articles. On average, treatments designed to reduce expressive responding shrink measured partisan bias by about 25%. Across the 242 survey questions in the data, treatments increase the correlation between the average Democrat’s and Republican’s beliefs from 0.81 to 0.86. Contrary to expectations derived from the two leading theories of expressive responding, misreporting (“cheerleading”) and congenial inference, there is no evidence that expressive responding increases in partisan identity strength or educational attainment. As research on expressive responding enters its third decade, greater emphasis on design-based tests of mechanisms may help build a firmer understanding of the nature and substantive importance of expressive responding—namely, whether the forces that produce expressive responding in surveys also shape real-world political judgments.
