Why Misinformation Must Not Be Ignored

Recent academic debate has seen the emergence of the claim that misinformation is not a significant problem. We believe that the arguments used to support this minimizing position are flawed, particularly if interpreted (e.g., by policymakers or the public) as suggesting that misinformation can be safely ignored. Here, we rebut the two main claims, namely that misinformation is not of substantive concern (1) due to its low incidence and (2) because it has no causal influence on notable political or behavioral outcomes. Through a critical review of current literature, we demonstrate that (1) the prevalence of misinformation is non-negligible if reasonably inclusive definitions are applied and that (2) misinformation has causal impacts on important beliefs and behaviors. Both scholars and policymakers should therefore continue to take misinformation seriously.
