The study of phenomena across nine dimensions: spacetime, probability, initial conditions, physical laws, mathematical structures, and logical systems. In 9D sciences, the framework includes different ways of reasoning—different inference rules, different definitions of validity, different concepts of truth. 9D sciences investigate how argument, proof, and rationality vary across dimensional slices, how a claim that's logically valid in one system could be fallacious in another, and what kind of discourse could exist in universes where the law of non-contradiction doesn't hold. This is the science of radical cognitive diversity—the recognition that your logic is just one logic among infinite possibilities, not the logic.
