Great Man Theory
Great Man Theory is the historical concept that certain exceptional individuals, rather than structural forces, determine the course of history. These 'great men' appear unpredictably, step outside the normal rules of cause and effect, and redirect events in ways no model could anticipate. The theory presents the ultimate challenge to any attempt at historical prediction.
The term originates with 19th-century historian Thomas Carlyle, who argued that 'the history of the world is but the biography of great men.' His view opposed the emerging structural theories of Marx and others, who saw history as driven by economic forces, class conflict, and material conditions, not individual genius.
In the context of Predictive History's psychohistory framework, great men are the 'edge case' problem: the moment in a mathematical model when an outlier breaks the system. Isaac Asimov recognized this in the Foundation series, his psychohistory model works for mass societies but is disrupted by a character called the Mule, a telepathic mutant who bends the predictions. Asimov's solution was the Second Foundation: a hidden group of experts who monitor the AI model and correct it for great-man disruptions.
Historical examples include Julius Caesar (ended the Roman Republic), Genghis Khan (built the largest land empire in history), and Vladimir Putin, who rose from obscurity to dominance in Russia with no inherited elite status, suggesting an almost telepathic ability to read and influence people.

Frequently asked questions
What is the Great Man Theory of history? ＋
Great Man Theory, originated by historian Thomas Carlyle, argues that history pivots on extraordinary individuals, not structural forces. Figures like Caesar, Napoleon, or Putin reshape civilizations in ways no economic or sociological model could predict, making them the fundamental challenge to any science of historical forecasting.
Why is the Great Man Theory a problem for psychohistory? ＋
Psychohistory models work on statistical averages across millions of people. But great men, by definition, are outliers who override the average. Isaac Asimov acknowledged this in Foundation by inventing the Second Foundation: a team of human monitors who watch the AI model and manually correct it whenever a great man appears.
