Public Perceptions of Poll Results Don’t Necessarily Depend on Data Quality

Michael W. Traugott, Institute for Social Research, University of Michigan

 

Ever since the advent of public polling in the United States and the marriage of pollsters with media organizations who distribute their results, a key concept is the role they serve in a representative government. In The Pulse of Democracy (1940), Gallup and Rae argued that the role of public opinion is essential to the development and maintenance of democracy and that public polls give citizens a continuous opportunity to express their policy preferences and attitudes. Of course, elections help in this regard, but they are infrequent. Not all issues are discussed during a campaign, and new issues can arise that the candidates never considered. Public acceptance of poll results rests on an assumption that consumers of such information have confidence in the accuracy, trustworthiness, and informative value of their results. Recent research framed by the theory of motivated reasoning (Kunda 1990; Lodge & Taber 2000; Taber & Lodge 2006) suggests that this assumption has come into question.

Rather than consuming new findings as a way to update current attitudes and beliefs, motivated reasoning researchers find that in many circumstances an individual will find results less credible when they suggest that a majority of the public are reported to have an opinion opposite the one that person holds. This can result in counterarguing against the results or rejecting them outright. Some research suggests that this phenomenon is more likely to occur among people who are more politically knowledgeable or sophisticated. This finding has been produced in survey-based experiments where, after respondents’ views are measured, they are randomly exposed to simulated results from a poll showing a majority of people agree or disagree with their view. These results have been reproduced in studies involving both policy issues and trial heat poll results in the United States (Kuru , Pasek & Traugott 2017, 2019, 2022; Madson & Hillygus 2019), as well as in Mexico (Aguilar, Moreno & Traugott 2018) and England (Aguilar & Traugott 2024).

The strength of the motivated reasoning phenomenon varies by issue and among different subgroups in the population. In the current polarized state of politics in the United States, the relationship seems to be stronger among more polarized individuals and for self-reported conservatives compared to liberals and moderates (Traugott 2024). Since most of the research has been conducted in the context of surveys with heavy political content, it is also possible that motivated reasoning would not appear or would be less prominent in other domains of attitudes or beliefs or when experiments are conducted in surveys with lower or no political content (Groenendyk and Krupnikov 2020).

There can be real world consequences for individuals who engage in motivated reasoning. For example, distrust in government policies with regard to COVID seemed to produce lower protective behavior rates (Kerr, Panagopoulos and van der Linden 2021). And the phenomenon of “unskewing” the polls (Cohn 2024) derives from individuals who don’t

believe the results from the trial heat polls showing their candidate is trailing. However, the most serious consequences may come from the reluctance of some members of society to acknowledge that elected officials and public policy makers should consider the results from polls that suggest the need for new or revised public policies or dissatisfaction with a current law or policy. That represents a fundamental challenge to our representative form of government.
