How different incentives reduce scientific misinformation online

Several social media employ or consider user recruitment as defense against misinformation. Yet, it is unclear how to encourage users to make accurate evaluations. Our study shows that presenting the performance of previous participants increases discernment of science-related news. Making participants aware that their evaluations would be used by future participants had no effect on accuracy. Lastly, monetary rewards have the largest effect on accuracy. Our study provides support for the idea that a person’s motivation is an essential component of their propensity to be vigilant online and that it is possible to devise strategies to strengthen this motivation.
