A Theoretical Physicist Grapples With the Math of Consciousness

Looking at the various theories, she is not very happy

She’s not very happy with what she sees: The currently most popular mathematical approach to consciousness is integrated information theory, IIT for short. It was put forward by a neurologist, Giulio Tononi, in two thousand and four. In IIT, each system is assigned a number, that’s big Phi, which is the “integrated information” and supposedly a measure of consciousness. The better a system is at distributing information while it’s processing the information, the larger Phi. A system that’s fragmented and has many parts that calculate in isolation may process lots of information, but this information is not “integrated”, so Phi is small. For example, a digital camera has millions of light receptors. It processes large amounts of information. But the…

Why Is Science Growing Comfortable with Panpsychism (“Everything Is Conscious”)?

At one time, the idea that “everything is conscious” was the stuff of jokes. Not any more, it seems

A recent article at New Scientist treats panpsychism as a serious idea in science. That’s thanks to the growing popularity of neuroscientist Giulio Tonioni’s Integrated Information Theory (IIT), which offers the opportunity for mathematical modeling, along with the implication that inanimate matter and/or the universe may be conscious. If IIT continues to gain a sympathetic hearing, panpsychism could become, over time, a part of normal science.

Can Machines Be Given Consciousness?

A prominent researcher in consciousness studies offers reasons for doubt

Two theories of human consciousness are about to be tested in a historic contest. Integrated Information Theory (IIT) of consciousness and rival Global Workspace Theory (GWT) have sharply different implications for consciousness in machines.

Quest for Consciousness: A Historic Contest Is Announced

The two theories to be tested pit "information processing" against "causal power" as a model of consciousness. One side must admit it is wrong

Consciousness is a slippery concept but the two prominent theories make different predictions as to which part of the brain will become active when a person becomes aware of an image; thus they can be tested by neuroscientists.
