The Changing Nature of Mass Belief Systems: The Rise of Concept and Policy Ideologues

Abstract

ABSTRACT The proportion of the American electorate that is “constrained” by ideology has risen dramatically since Philip E. Converse suggested, in the early 1960s, that ideology is the province of only a small fraction of the mass public. In part, the rise of ideological voters has been obscured by the tendency of scholars after Converse to equate them with those who use terms referring to ideological concepts, such as liberal and conservative, in open-ended interviews. These “concept ideologues,” however, are not the only members of the public whose political opinions show evidence of ideological constraint. There is also a growing segment of the public, the “policy ideologues,” who take positions on three or more policy issues but do not happen to mention ideological concepts. Policy ideologues prove to be as politically knowledgeable as concept ideologues; their attitudes are nearly as constrained across issues and over time; and their policy stances usually “make sense” as liberal or conservative—not surprisingly, as they are almost as willing as concept ideologues to label themselves ideologically, when asked. By 2012, the portion of the public consisting of concept and policy ideologues had reached 42 percent. It declined to 38 percent in 2016, but was still a far cry from the 12 percent of the electorate whom Converse identified as ideologues or near ideologues as of 1956.
