Science Writer: No Way To Tell If AI Is Conscious

Absent a definition of consciousness, it might not be possible to prove extravagant claims wrong
The difficulty of defining consciousness could very well be one of the reasons why tech moguls can get away with extravagant claims about conscious AI. Read More ›

Leading Consciousness Theory Slammed as “Pseudoscience.” Huh?

Integrated Information Theory’s panpsychist leanings are the 124 neuroscientist critics’ real target
Curiously, the coverage at Nature doesn’t address the critics’ concerns about IIT’s panpsychism. But it’s at Nature’s doorstep whether or not it’s noted. Read More ›

GWT: A Leading Consciousness Theory Depends on Information Theory

Not mechanism. If Global Workspace Theory (GWT) is a good approach to consciousness, there is no “consciousness spot” in the brain.

Recently, we have looked at the Integrated Information Theory (IIT) of human consciousness, as set out by well-known Allen Institute neuroscientist Christof Koch. Another leading contender (and rival) is Global Workspace Theory (GWT) — it pictures the brain as an orchestra with many conductors. IIT is panpsychist in orientation (the universe participates in consciousness; human consciousness is the most highly developed instance) whereas GWT uses information theory to capture an image of consciousness via observations of the brain at work. A recent essay in Psyche by two GWT proponents, Morten L. Kringelbach and Gustav Deco, introduces us to GWT: … given the distributed nature of the brain hierarchy, there is unlikely to be just a single ‘conductor’. Instead, in 1988 Read More ›
