Inverse zombies, anesthesia awareness, and the hard problem of unconsciousness.
Consciousness and cognition December 1, 2008 George A Mashour, Eric LaRock
Philosophical p-zombies are imagined beings that behave like humans but lack consciousness, used to challenge physicalist theories of mind. Inverting this concept yields i-zombies: beings that appear unconscious but are actually conscious. A real-world approximation of i-zombies exists in anesthesia awareness, where 1-2 per 1000 patients under general anesthesia become conscious during surgery despite appearing unconscious due to paralysis and intubation. Additionally, 22% of patients in a recent study reported dreaming during anesthesia. P-zombies raise the hard problem of explaining qualia; i-zombies pose the practical problem of detecting qualia. The work compares these concepts and examines the hard problem of unconsciousness through anesthesia awareness.
