Applying Exploratory Learning Methods To Sociopolitical Beliefs And Cognition., Sarah French

Electronic Theses and Dissertations

Americans are polarized along party lines across a variety of sociopolitical issues, including climate change and sustainability issues. Sociopolitical messaging often triggers biased processing that results in defensive rejection or biased elaboration (i.e., counterarguing) of belief-incongruent information. The current research examined whether exploratory learning activities, primarily applied in STEM-education research, can foster belief updating about polarized sustainability issues. Exploratory learning encourages people to engage with learning materials and arrive at their own conclusions before receiving direct instruction/messaging. In two experiments, participants reported their beliefs about carbon taxes and electric vehicle incentives (among other issues) before and after receiving counter-attitudinal persuasive …
