Navigating Scientific Uncertainty and Personal Beliefs

Today’s episode is about a narrow question and a broad question. The narrow question is: Is ice cream secretly good for you? The broader question is about the nature of uncertainty and truth, how diet science actually works, and how bias plays a role in scientific discovery. Our guest is public health historian and journalist David Johns, who has reported on ice cream science for The Atlantic.
