- IDEA 1 OF 8
Governments often act against their interests
Tuchman studies a strange pattern in history: governments repeatedly pursue policies that harm their own interests.
She calls this folly, and asks why leaders persist with such policies even when warned.
- IDEA 2 OF 8
Folly has three conditions
Tuchman sets a strict definition: the policy must have been seen as harmful at the time, a feasible alternative must have existed and the decision must have been made by a group rather than one individual.
- IDEA 3 OF 8
Troy let in the horse
Tuchman begins with the legend of the Trojan Horse, when the Trojans brought the enemy's gift inside their walls despite warnings.
She uses it as a symbol of folly. Warnings went unheeded.
- IDEA 4 OF 8
Renaissance popes provoked the Reformation
Tuchman describes how corrupt and worldly popes of the Renaissance ignored calls for reform.
Their behaviour helped provoke the Protestant Reformation, splitting the church. Their blindness cost them dearly. Reform came too late.
- IDEA 5 OF 8
Britain lost America
Tuchman describes how British governments in the eighteenth century pursued policies that alienated American colonists.
Despite warnings, they pushed until the colonies rebelled. The empire lost its colonies. Arrogance proved costly.
- IDEA 6 OF 8
Vietnam was a modern folly
Tuchman describes how successive American governments deepened involvement in Vietnam, despite evidence that the war could not be won.
Pride and fear kept them going. Admitting error seemed impossible. The cost was huge.
- IDEA 7 OF 8
Power can blind leaders
Tuchman argues that power often makes leaders resistant to evidence and advice.
Self-deception and stubbornness lead them to repeat mistakes. Wishful thinking replaces careful judgement in the corridors of power.
- IDEA 8 OF 8
Learning requires humility
Tuchman suggests that avoiding folly requires leaders willing to listen and change course.
Humility is a key safeguard. Leaders who can admit mistakes protect their nations from disaster. Listening matters.
