In system theory, differentiation is the increase of subsystems in a modern society to increase the complexity of that society. Each subsystem can make different connections with other subsystems, and this leads to more variation within the system in order to respond to variation in the environment.

Differentiation that leads to more variation allows for better responses to the environment, and also for faster evolution (or perhaps sociocultural evolution), which is defined sociologically as a process of selection from variation; the more differentiation (and thus variation) that is available, the better the selection.^{[1]: 95–96}
