Students’ trust in research-based results about potential health risks presented in popular media

Abstract

Socioscientific issues receive considerable public attention and there are concerns that people in general are not able or willing to deal with information at odds with what they believe to be true. In this study, we focused on students’ beliefs about two controversial issues: whether consumption of the artificial sweetener aspartame and use of cell phones, respectively, represent any serious health risks. Our aim was to investigate whether students’ trust in the information was related to prior beliefs, the nature of the message, and students’ critical reading strategies. Results showed interactions between prior beliefs about the issues and text condition (risk vs. no risk) on trust in conclusions that indicated a confirmation bias assumption. Additionally, students trusted conclusions ascertaining that there were risks more than conclusions ascertaining that there were no risks. Finally, students’ self-reported use of critical reading strategies implied less trust in both types of conclusions.
