Toward a Social-Technological System that Inactivates False Rumors through the Critical Thinking of Crowds

Critical thinking is an important part of media literacy. It allows people to find facts among rumors and to inactivate false information. Such abilities are essential when social media is flooded with rumors during disaster response. We envision a social technological system in which critical thinking is crowd-sourced: Individuals benefit from othersâ criticisms of false information, and the system inactivates the spread of false information. To test the plausibility of this system, we examined the effect of exposure to criticisms on peopleâs decision to spread rumors in social media. When people were exposed to criticisms before rumors, the proportion of responses aimed at stopping the spread of rumors was significantly larger than when people were exposed to rumors before criticisms. We identified some psychological factors that could explain this effect. Based on our results, we discuss practical implications for developing a social-technological system that harnesses the critical thinking of crowds.
