How can a medical recommendation that harms people survive for years inside one of the most educated, evidence-focused professions in the world?

In this episode of Reimagine Healthcare, Noah Volz begins a three-part series on what Dr. Marty Makary calls blind spots in medicine — the places where healthcare gets stuck on ideas that are incomplete, outdated, or wrong.

This is not an anti-doctor episode. It is a systems episode.

Medicine is a human system. And human systems have failure modes: cognitive dissonance, professional identity, protocols, liability fear, institutional embarrassment, habit, and the pressure to move quickly through busy clinical settings.

This episode uses two examples to make the problem concrete: appendicitis and peanut allergy.

For more than a century, appendicitis was treated with one dominant reflex: remove the appendix. But research has shown that some uncomplicated cases may be managed with antibiotics first. That does not mean surgery is obsolete. It means patients should understand when there is a real choice.

The peanut allergy story is even more uncomfortable. Around the year 2000, major guidance encouraged peanut avoidance for young children and pregnant or breastfeeding mothers in higher-risk families. The goal was prevention. But later evidence showed that early peanut exposure, under appropriate guidance, could substantially reduce peanut allergy risk.

The lesson is not that medicine is fake or that patients should ignore doctors. The lesson is that confident recommendations are not always the same as well-updated recommendations.

And in Southern Oregon, this matters.

When access is thin, clinician time is scarce, and patients feel pressure to say yes quickly because getting care is hard, outdated guidance can linger longer. That makes local health literacy, better patient questions, and a less defensive healthcare culture even more important.

In this episode, you’ll learn:

• Why medical blind spots form
• How cognitive dissonance affects clinicians and institutions
• Why professional identity can make evidence harder to accept
• What appendicitis reveals about surgical reflexes
• What peanut allergy teaches us about fear-based guidance
• Why updates in medical evidence can take years to reach everyday care
• How Southern Oregon patients and parents can ask better questions without becoming cynical
• Why “thoughtful trust” is healthier than blind trust or total distrust

The key question from this episode is simple:

Is this still the best evidence?
