Case Study 1: The Lobotomy — When a Nobel Prize Became a Sunk Cost
Overview
The prefrontal lobotomy is the most dramatic case of sunk cost maintaining a harmful medical practice in the 20th century. Between 1936 and the late 1960s, an estimated 40,000-50,000 lobotomies were performed in the United States alone. The procedure was endorsed by the highest levels of medical authority, including the Nobel Prize. And it was continued for at least a decade after clear evidence demonstrated that it caused more harm than good.
Key Events
| Year | Event | Sunk Cost Implication |
|---|---|---|
| 1935 | Moniz performs first leucotomy | Initial investment begins |
| 1936 | Freeman adapts procedure for US | Institutional infrastructure develops |
| 1940s | Tens of thousands of procedures performed | Career, institutional, and narrative investment deepens |
| 1949 | Nobel Prize to Moniz | Maximum prestige validation — sunk cost peak |
| 1950s | Counter-evidence accumulates | Switching cost now includes moral dimension |
| 1954 | Chlorpromazine introduced | Alternative available — but switching cost prevents rapid adoption |
| 1960s | Practice declines but continues | Generational turnover eventually overcomes sunk cost |
| 1967 | Freeman's last lobotomy (patient dies) | Individual sunk cost maintained practice to the bitter end |
The Five Components in Action
Career: Freeman alone performed ~3,500 lobotomies. His entire career — publications, lectures, professional identity — was built on the procedure. Abandoning it meant acknowledging that his life's work had harmed patients.
Reputation: The Nobel Prize created an institutional validation that could not easily be retracted. Psychiatry's reputation as a medical specialty was partly built on the claim that it had a surgical intervention for mental illness.
Textbook: Medical school curricula incorporated lobotomy as a treatment option. Clinical guidelines included it. Training programs taught it.
Funding: Hospital surgical departments had invested in the procedure. Insurance reimbursement structures supported it.
Identity: Psychiatrists who performed lobotomies saw themselves as surgeons treating a biological disease. The procedure validated psychiatry's claim to be a medical discipline rather than a "soft" field.
Discussion Questions
- Should the Nobel Committee revoke Moniz's prize? What would revocation signal about the reliability of the Nobel process?
- How could the medical establishment have detected the harm earlier? What structural changes would have enabled faster correction?
- Compare the lobotomy case to the opioid crisis. What structural similarities exist in the sunk cost dynamics?
- The lobotomy patients were disproportionately women and institutionalized individuals with limited autonomy. How does power asymmetry interact with sunk cost?
