Complexity
A wide literature exists on complex/non-linear systems. Highlighting aspects of complicated causal networks. This provides some ideas in categorising, analysing and understanding mechanisms of agent interaction.
The existing work on complexity can be related to the analytical themes of The Mangle: agency, contingency amd emergence.
Complexity
Complex systems of interactions where it is difficult to track physical explanations with precise and discrete causal paths. Expand vocabulary of simple cause and effect in linear systems to non-liniear cases, e.g. inhibition, amplification, feedback loops, emergent causality, cascading effects.
General Studies
Examples in economics and biology.
Specific to Social Studies
Social interactions are complex: context-dependent, time-sensitive, unrepeatable.
Ideas in Complex Systems
Distribution of information in complicated societal system. Based on Gladwell's Tipping Point.
Agents
Law of the Few
Stickiness
Contingency
Power of Context
