It’s when the higher scale of a system has more information associated with its causal structure than the underlying lower scale. I don&#x27;t understand why the writer invents new (grand) terms to discuss phenomena that is already widely studied. Information as a function of scale in a system is well known phenomenon in physics and complex systems theory. Systems different in microscopic scale can behave similarly in macroscopic scale. Renormalization group formalizes this emergent principle of universality. Multiscale information theory is generalization of it.…</p><p><a href="https://hackerpaper.kaipfister.de/p/1409.4708/">Paper and discussion history</a>.
