Generative science is an area of research that explores the natural world and its complex behaviours. It explores ways 'to generate apparently unanticipated and infinite behaviour based on deterministic and finite rules and parameters reproducing or resembling the behavior of natural and social phenomena'. By modelling such interactions, it can suggest that properties exist in the system that had not been noticed in the real world situation. An example field of study is how unintended consequences arise in social processes. Generative science is an area of research that explores the natural world and its complex behaviours.

Self-organizing natural systems are a central subject, studied both theoretically and by simulation experiments. The study of complex systems in general has been grouped under the heading of 'general systems theory', particularly by Ludwig von Bertalanffy, Anatol Rapoport, Ralph Gerard, and Kenneth Boulding. These sciences include psychology and cognitive science, cellular automata, generative linguistics, natural language processing, connectionism, self-organization, evolutionary biology, neural network, social network, neuromusicology, quantum cellular automata, information theory, systems theory, genetic algorithms, computational sociology, communication networks, artificial life, chaos theory, complexity theory, network science, epistemology, quantum dot cellular automaton, quantum computer, systems thinking, genetics, economy, philosophy of science, quantum mechanics, cybernetics, digital physics, digital philosophy, bioinformatics, agent-based modeling and catastrophe theory. The development of computers and automata theory laid a technical foundation for the growth of the generative sciences. For example: One of the most influential advances in the generative sciences as related to cognitive science came from Noam Chomsky's (1957) development of generative grammar, which separated language generation from semantic content, and thereby revealed important questions about human language. It was also in the early 1950s that psychologists at the MIT including Kurt Lewin, Jacob Levy Moreno and Fritz Heider laid the foundations for group dynamics research which later developed into social network analysis.
