Chaos theory is a theory that holds that some systems, such as weather, are ultimately unpredictable because of the effects of small scale events that cannot be included in the prediction equations. In mathematics, chaos theory describes the behavior of certain dynamical systems, those whose states evolve with time, that may exhibit dynamics that are highly sensitive to initial conditions, often referred to as the butterfly effect.

Society for Chaos Theory in Psychology & Life Sciences

The Society is an international forum bringing together researchers, theoreticians and practitioners involved in the application of dynamical systems theory, self-organization, neural nets, fractals, cellular automata, agent-based modeling and related forms of chaos theories to psychology and the life sciences. Resources available include a data library, data analysis and other articles on the subject, as well as a blog and online discussion forum.
