The efficacy of interventions in reducing belief in conspiracy theories: A systematic review

In this study, the authors conducted a systematic review to identify and assess interventions that have sought to counter conspiracy beliefs. Conspiracy beliefs have become a topic of increasing interest among behavioural researchers. While holding conspiracy beliefs has been associated with several detrimental social, personal, and health consequences, little research has been dedicated to systematically reviewing the methods that could reduce conspiracy beliefs. 

Out of 25 studies (total N = 7179), researchers found that while the majority of interventions were ineffective in terms of changing conspiracy beliefs, several interventions were particularly effective. In the study, interventions that fostered an analytical mindset or taught critical thinking skills were found to be the most effective in terms of changing conspiracy beliefs. These findings are important as future research is developed to combat conspiracy beliefs.
