Dragon King Theory
The idea that some extreme events aren't just rare outliers but arise from distinct, identifiable mechanisms — positive feedback loops, tipping points, and phase transitions that amplify them beyond normal scale.

Origin
Developed by physicist Didier Sornette at ETH Zurich, first formally described in a 2009 paper. The name is a double metaphor: "king" for extreme size, "dragon" for unique origin — distinguishing these events from Nassim Taleb's "black swans," which are assumed to be unpredictable. Sornette argues that many crises (financial crashes, earthquakes, epileptic seizures) are actually Dragon Kings — born of identifiable mechanisms like positive feedback loops — and may therefore be partially predictable.
