The Impact of Information Provided by Political Elites on Individual Trade Policy Preferences: A Result of Political Knowledge or Interest?

Are people who are more knowledgeable and interested in trade policy more likely to change their preferences regarding trade agreements compared to their less knowledgeable and less interested counterparts on receiving new information from politicians? This study responds to this question by developing a framework that distinguishes knowledge from interest and assesses it using an original survey conducted on voters during the 2020 US election campaign. Assessing whether information about trade agreements provided by political elites shifts individuals’ trade preferences and whether knowledge and interest condition susceptibility to such information reveals that people knowledgeable and interested in trade policy are less likely to change their original preference. Together, the results sharpen the existing theories by establishing knowledge and interest as moderators of trade opinion change in low-salience trade settings.
