Joe Rogan Experience #2563 - Dan Richards · Aired Oct 8, 2026
Claim summary · not a verbatim quotation
American Civil War doctors had a 40% survival rate for similar procedures.
The finding
What the evidence shows
Dan describes Civil War survival as about forty percent and surgeons as half as good as the Inca. The primary paper reports Civil War cranial-surgery mortality of forty-six to fifty-six percent but explicitly says short- and long-term survival rates are unknown. Complementing mortality is not the same as measuring comparable long-term survival. Different injuries, follow-up and selection prevent a controlled two-to-one surgical-skill comparison.
