What Does 'Information' Mean in Integrated Information Theory?

Integrated Information Theory (IIT) aims to explain consciousness by linking its fundamental properties to physical systems. A central concept is information, which IIT treats as intrinsic to a system and tied to its causal structure. This paper argues that the information in IIT should be understood through a causal-manipulability view, where information is defined only when it participates in causal relationships. These causal links are revealed by interventionist procedures based on Woodward's and Pearl's manipulability theories of causation. The analysis clarifies how information operates within IIT's framework.
