This headline is an outstanding example of how misinformation is perceived in the public arena. The headline makes a causal assumption that misinformation is “getting in the way” of recovery from the hurricane’s devastating impact. The degree of accuracy of this assumption is a question for further study and empirical examination, but the very assumption that misinformation has a direct causal impact on relief efforts with significant negative consequences is noteworthy. And newsworthy. And is part of what motivated this report. Information, and misinformation, is everywhere—on our phones, televisions in the gym, social media. Some of this misinformation is brain candy, simple entertainment, and inconsequential; some of it, though, has the potential to impact public health, inform policy responses, and shape people’s perceptions of the world. If misinformation about science leads to beliefs that are in conflict with accepted science, the consequences can be profound. False perceptions and beliefs may lead to behaviors and support for policies that are not supported by accepted science and/or are not aligned with individual preferences and goals, with negative consequences for individuals, communities, and broader society.
