IIT (Integrated Information Theory)

Integrated Information Theory (IIT) is a scientific framework that seeks to explain the nature of consciousness. It proposes that consciousness arises from the way information is integrated within a system; specifically, when a system's parts interact in a way that creates unified and irreducible information. This means that the experience cannot be broken down into simpler components without losing essential meaning. IIT suggests that the level of consciousness correlates with how much integrated information a system possesses, implying that more interconnected and complex systems—like the human brain—generate richer conscious experiences.
