From a ToK System, science is a particular branch in the evolution of justification systems. Initially in smaller and less complex societies, justification systems were undifferentiated, meaning that the shared narratives that coordinated the populations of individuals would be a global religious-political narratives that explained how the world worked and what was good and bad. As societies grew in complexity, justification systems became more complicated and differentiated into various domains such as law, politics, mathematics and religion.

The ToK System suggests that science was a justification system built on the value of accuracy and depicts how science exists in the dimension of culture and functions to map the four dimensions of complexity. The following reciprocal feedback loop provides the basic three step process that underlies the scientific method and allows scientists to build increasingly accurate representations of the universe and the objects in it.
