Editors Reads Verdict
Tuchman's most explicitly argued book poses one of history's most urgent questions: why do governments persistently pursue disastrous policies when alternatives are available? The answer, illustrated through four case studies spanning three millennia, is both carefully documented and deeply unsettling.
What We Loved
- The central question — why governments act against their own interests — is as urgent as any in political thought
- The Vietnam case study is one of the best short accounts of that war's policy failures
- Tuchman's standards for what counts as genuine 'folly' are precisely defined and consistently applied
Minor Drawbacks
- The four case studies span so much time that some readers find the comparative framework strained
- The Renaissance papacy section assumes more knowledge of Church history than general readers may have
Key Takeaways
- → Wooden-headedness — the refusal to update beliefs in light of contrary evidence — is the defining characteristic of political folly
- → Folly requires that a wiser alternative was available and recognized at the time
- → Governments pursue disastrous policies not from lack of information but from the political costs of changing course

Why Governments Act Against Themselves
Barbara Tuchman’s central question in The March of Folly is deceptively simple: why do governments — with full information about the consequences, with advisers who can see the alternative — pursue policies that are obviously, demonstrably contrary to their own interests? Not the folly of ignorance, but the folly of wooden-headedness: the refusal to change course even when the disaster is visible.
Tuchman’s definition of folly is precise. It must meet three criteria: the policy must have been perceived as counter-productive in its own time; a workable alternative must have been available; and the policy must have been the product of a group, not an individual, and must have persisted across more than one political lifetime. This rigor is important — it prevents the concept from becoming a retrospective judgment applied to anyone who turned out to be wrong.
Four Case Studies
The book examines four episodes that meet these criteria: the Trojan rulers who brought the wooden horse inside the walls despite warnings; the Renaissance popes whose corruption and political mismanagement drove northern Europe into the Protestant Reformation; the British handling of the American colonies that produced the Revolution; and, in the book’s most substantial section, American policy in Vietnam from Truman through Nixon.
The Vietnam section is the heart of the book and one of the best short accounts of that catastrophe’s policy dimensions. Tuchman traces how successive administrations received intelligence and advice that contradicted their assumptions, and how each administration found ways to discount or ignore that evidence rather than accept the political costs of acknowledging failure. The pattern is not stupidity — the individuals involved were often highly intelligent — but a structural inability to accept the consequences of admitting error.
Wooden-Headedness as Historical Force
Tuchman’s ultimate argument is about the psychology of institutional power: that the commitment of resources and prestige to a course of action creates irresistible psychological pressure to justify the commitment by doubling down rather than cutting losses. This dynamic — which behavioral economists now describe as the sunk-cost fallacy operating at civilizational scale — is as visible in contemporary politics as in the Trojan Horse.
Our rating: 4.5/5 — Tuchman’s most argumentative book asks one of the most important questions in political thought and answers it with characteristic precision and narrative force.
