In this episode, Dr. Bradley Block interviews Dr. Nini Munoz, who shares strategies to help physicians effectively navigate and combat health misinformation. Known for her platform Nini and the Brain, Dr. Munoz rose to prominence during the COVID-19 pandemic by demystifying complex clinical data. She explains common statistical manipulations, like base rate fallacy and absolute versus relative risk, using examples such as raw milk claims and fluoride debates. Dr. Munoz emphasizes the difference between risk (quantifiable likelihood of harm) and hazard (potential to cause harm), offering strategies to communicate these concepts to patients by aligning with their personal values. From addressing publication bias to advocating humility in science, this episode equips physicians to counter misleading headlines and foster trust with patients.
Three Actionable Takeaways:
- Spot Base Rate Fallacy – Adjust for population size when comparing health outcomes (e.g., pasteurized vs. raw milk hospitalizations) to avoid misleading absolute numbers and reveal true risk.
- Question Weak Effects – Scrutinize studies with inconsistent or marginal effects, like fluoride research, by checking for confounders, publication bias, or non-replicable results.
- Tailor Risk Communication – Frame health advice around patients’ personal risks (e.g., vaccine benefits for individual healthcare access) to make data relatable and actionable.
