RedNova News - Psychohistory is Coming,: ; Scientists Learning to Take Society's Temperature

Excerpt: "Among the newest of the enterprises - and closest to the spirit of Asimov's psychohistory - is a discipline called sociophysics. The name has been around for decades, but only in the 21st century has it become more science than slogan.

Like Asimov's psychohistory, sociophysics is rooted in statistical mechanics, the math used by physicists to describe the big picture when lacking data about the details. Nobody can track the trillion trillion molecules of air floating around in a room, for instance, but statistical mechanics can tell you how an air conditioner will affect the overall temperature.

In a similar way, science cannot describe how any given individual will behave. But put enough people together, Asimov's psychohistorian Hari Seldon reasoned, and laws of human interaction will produce predictable patterns - just as the way molecules move and interact determines the temperature and pressure of a gas."
