In this solo episode, Peter Attia tackles one of the most underappreciated skills in health optimization: scientific thinking itself. He explains why our brains are evolutionarily wired to resist it, how cognitive biases and social identity distort our interpretation of evidence, and why this problem is especially dangerous in today's misinformation-saturated health landscape. Attia offers five concrete mental tools — from noticing false certainty to judging process over conclusions — and a framework for identifying trustworthy experts. The episode is less about any single health intervention and more about building the meta-skill that makes all other health decisions more reliable. For both patients and clinicians, it's a rare and valuable primer on epistemic hygiene in medicine.
