On December 14th, 1799, George Washington's physicians did what medicine had done for two thousand years. They bled him. Three times. He was dead by evening. They were not reckless. They were following the most credentialed, most consensus-supported medical protocol in the Western world.

This episode is about what it took to dismantle that consensus, and what medicine had to build in its place. It covers James Lind's 1747 controlled trial aboard HMS Salisbury, the physician who proved that doctors were the disease vector and was driven to an asylum for it, the 1784 French royal commission that discovered the placebo effect while investigating a magnetic fraud, and Austin Bradford Hill's sealed envelopes - the design that finally removed personal responsibility from the clinician.

Episode 3 of The Tenth Man, a podcast about the specific mechanisms different domains have built to make dissent structurally impossible to ignore.

Show Notes:

The George Washington death account is historically well-documented; the three-to-four-liter blood removal figure is consistent across historical accounts but is a reconstruction based on recorded "bleedings" of specific volumes, not a single contemporaneous measurement. State it as the scholarly consensus estimate.

The Semmelweis mortality figures (10% and 30% peaks in the physicians' ward, under 2% in the midwives' ward) are from the historical record documented by Semmelweis himself and subsequent historians; the specific monthly variation has some range across sources. The orders of magnitude are not disputed.

The "removed personal responsibility from the clinician" phrase is from the 1948 BMJ editorial accompanying the streptomycin trial report. It is presented in the episode in its original context - as a description of the design's intention, not a criticism of it.
