Can we ever know what causes a chronic disease? In this episode, I’m joined again by Dr. Shoshana Herzig to finish a three-part miniseries on Bradford Hill and Doll’s attempts to prove that smoking caused lung cancer. We’ll talk about the first prospective cohort trial in history, 1960s “Fake News” from tobacco companies, public spats with the most famous statistician of the 20th century, and the development of the Bradford Hill Criteria, a guideline, however imperfect, that gives doctors a blueprint to finally figure out what causes diseases.
