Key Takeaways: Field Autopsy — Medicine
The Big Idea
Medicine has the longest documented history of error (~2,500 years), the highest stakes (human lives), and the most sophisticated correction infrastructure (RCTs, Cochrane, guidelines) of any field. It is both the most self-correcting and the most in need of correction — and its ~40% reversal rate and 17-year implementation gap set the benchmark against which all other fields should measure themselves.
Medicine's Arc in Four Eras
| Era | Period | Correction Status |
|---|---|---|
| Humoral medicine | ~400 BCE – ~1850 | No correction mechanism; unfalsifiable theory sustained by authority cascade |
| Early correction | ~1850 – ~1950 | Germ theory revolution; correction through outsider evidence + crisis + generational replacement |
| RCT era | ~1950 – ~1990 | Powerful correction tool but adoption uneven; major errors (lobotomy, thalidomide) still occurred |
| EBM era | ~1990 – present | Sophisticated infrastructure but failure modes persist; opioid crisis, replication crisis, medical reversal |
Key Failure Modes in Modern Medicine
- Inverted evidence hierarchy: Practices adopted based on weak evidence, embedded institutionally, then tested rigorously (if ever) → ~40% reversal rate
- Eminence-based medicine: Authority cascade operating within EBM framework through guidelines and key opinion leaders
- Incentive misalignment: Evidence production corrupted by pharmaceutical funding; procedures incentivized over non-intervention
- Therapeutic inertia: 17-year gap between definitive evidence and widespread practice change
- Correction infrastructure blind spot: Tools address evidence quality but not evidence production incentives
The Medical Benchmark
If your field has less correction infrastructure than medicine, and medicine still gets ~40% of tested practices wrong, your field's error rate is likely higher. The question is not "is my field doing as well as medicine?" but "what is my field's equivalent of the RCT, and does my field even have one?"
Epistemic Audit — Chapter 23 Addition
Map your field onto medicine's four eras. Identify your field's equivalent of RCTs, Cochrane, and guidelines. Estimate your field's "reversal rate" if established practices were rigorously tested.
