G2WS was created to make the logic of a complex world model tangible and explorable. Its purpose is not to predict the future with certainty, but to let users make their assumptions explicit—about technology, energy, climate, economics, demographics or public policy—and then explore their consequences in a consistent, interconnected simulation. In that sense, G2WS turns modelling into a new form of experimentation: rather than discovering entirely new facts about the world, it helps us understand, with remarkable efficiency, what follows from what we already believe or know. By making those chains of consequences visible, G2WS provides a practical environment for testing hypotheses, comparing worldviews and improving the quality of strategic reasoning.
