This course confronts the growing challenge of misinformation and disinformation about interventions aimed at improving health, at the individual and population level. Through illustrative examples involving vaccinations, supplements, exercise and diet, you will learn to recognize common patterns and strategies through which misinformation is spread. We will also cover strategies to fight misinformation, including debunking, crafting counter messages and regulatory responses at the systemic level. Prerequisite: SPH 200 or consent of instructor.
