Abstract: Excessive volatility : irrational behaviours or intellectual dividing ? The main assumption to explain high volatility of markets is the irrational behaviours of investors. This analysis contrasts the « good » economy with the « bad » stock exchange. The author presents the origins of this concept and describes the dividing it implies in modelling field. He explains that this intellectual dividing is based on a probability assumption and if this assumption isn't verified, the dividing isn't possible. JEL classifications : D81, D82, D84, G14
