CONCEPT
Psychohistory
Asimov's fictional science of predicting the trajectory of large populations using statistical laws — the most influential speculative model for what data-scale intelligence might reveal about human behavior.
Psychohistory is the fictional mathematical discipline at the heart of Asimov's Foundation series, invented by the character Hari Seldon. It proposes that individual human behavior is unpredictable but the behavior of very large populations follows statistical regularities comparable to the laws of thermodynamics. Psychohistory's premise — that there is a tractable signal in aggregate human conduct — has become more relevant since large language models demonstrated that human expression at scale does encode deep, exploitable regularities.

In the Orange Pill Asimov volume, psychohistory is treated as a surprisingly prescient early formulation of what training a model on civilizational-scale text actually does. The Foundation novels ask: if you could predict the arc of a galactic civilization thousands of years in advance, would you publish the predictions or conceal them? Psychohistory assumes concealment is required — if the population knows the predictions, behavior changes and predictions fail.
Large language models partially satisfy psychohistory's premises. They are trained on the largest
