RATIONALE: Targets sources explaining the concept of cause-effect power in IIT, which is vital for claims about physical existence and consciousness.

========================================================================

The 2008 work by Balduzzi on the Integrated Information Theory (IIT) focuses on the concept of 'cause–effect power,' a key principle in evaluating consciousness. The central idea is that consciousness is composed of integrated information, which cannot be reduced to the sum of its parts. This integrated information is quantitatively assessed through the cause–effect power that a system holds.

The cause–effect power is defined by how certain states of a system cause other states (cause power) and how these states are influenced by previous states (effect power). In this framework, consciousness is thought to arise from the system's capacity to generate a repertoire of possible past and future states, which exceed mere structural or functional correlations among components.

The theory posits that consciousness is measured by Φ (phi), indicating the capacity for integrated information. Systems with higher Φ are considered to have greater consciousness because they exhibit complex interactions that cannot be easily divided into independent parts. The formulation stresses that it is the system's causative interactions that determine this power, highlighting the irreducibility and unity aspects of conscious experience.

Ultimately, this approach argues that consciousness corresponds to high integrated cause–effect power, making it an intrinsic attribute of certain systems rather than something extrinsically added or layered upon physical processes.
