You can ace every exam, match into a top program, and still get quietly written off in your first week of a rotation. Vance Lehman, a Mayo Clinic neuroradiology professor who runs education for his department, spent two years researching why some trainees thrive and others stall. He argues the difference is almost never knowledge. It is the hidden curriculum, the unspoken expectations no one teaches you, and one bad first impression can spiral for the rest of training.

About this episode:
Vance Lehman is a Mayo Clinic neuroradiology professor and chief of neuroradiology education who, after stumbling on a 1960s grade-school research concept, spent over two years writing a practical guide for medical trainees. He defines the hidden curriculum as the unspoken expectations, invisible challenges, and stealth influences that shape who succeeds in training, and he argues it matters more in medicine than in any earlier stage of school because medicine is fundamentally experiential and social. He walks through concrete examples, from the script he recommends new rotators use with their attending on day one, to Daniel Kahneman's concept of excessive coherence and how it locks first impressions into self-reinforcing loops. He shares the small but career-altering mistakes he hears about from program directors across the country, and he challenges the common attending bias that younger trainees lack work ethic by pointing to Adam Grant's research on the illusion of moral decline. He pushes back on the false economy that says training is already too crowded to teach this, arguing that not teaching it costs more time than teaching it ever would. He closes with the single rule he wants every trainee to internalize: get the easy things right and be proactive, because one professional misstep can spiral, and the people doing things quietly in the background often get the worst perception.

Tune into our episode "2026 Cholesterol Guidelines: LDL goals, lipoprotein(a), and coronary calcium scoring," brought to you by Novartis Pharmaceuticals Corporation.

For the first time in eight years, LDL cholesterol goals have changed, and preventive cardiologist Seth Baum says the new guidelines are a long-overdue course correction. He breaks down the new LDL targets for your highest-risk patients, why the LDL hypothesis should be retired in favor of the LDL fact, why lipoprotein(a) screening finally belongs in every patient's workup, what a coronary calcium score over 300 really means for how aggressively you treat, and how to talk to statin-skeptical patients without losing their trust.
