Fighting misinformation or fighting for information?

To test the efficacy of various interventions aimed at improving the informational environment, we developed a model computing a global information score, which is the share of accepted pieces of reliable information minus the share of accepted pieces of misinformation.

Simulations show that, given that most of the news consumed by the public comes from reliable sources, small increases in acceptance of reliable information (e.g., 1%) improve the global information score more than bringing acceptance of misinformation to 0%. This outcome is robust for a wide range of parameters and is also observed if acceptance of misinformation decreases trust in reliable information or increases the supply of misinformation (within plausible limits).

Our results suggest that more efforts should be devoted to improving acceptance of reliable information, relative to fighting misinformation.
