Megan Scudellari discusses widely held — but false — beliefs about subjects like cancer screening, antioxidants, and overpopulation and considers why they are so hard to overcome: "These myths often blossom from a seed of a fact — early detection does save lives for some cancers — and thrive on human desires or anxieties, such as a fear of death. But they can do harm by, for instance, driving people to pursue unnecessary treatment or spend money on unproven products."
