On the causal efficacy of qualia: Philosophical zombies are fine-tuned, and implications for the quantum measurement theory

Summary

Consciousness may directly influence quantum mechanics, challenging our understanding of how mind and matter interact. This groundbreaking physics theory suggests that conscious experiences (qualia) play an active role in quantum processes, rather than being mere byproducts. The analysis shows that quantum states must be precisely fine-tuned to support consciousness, making purely physical "philosophical zombies" statistically improbable.

Abstract

We suggest that qualia have a causally efficacious role in quantum mechanics; an occurrence which explains how information about qualia can enter the physical environment. This is compatible with the unitary time-evolution of the quantum state if qualia are understood as effecting the beables of the de Broglie-Bohm interpretation or wavefunction collapse process rather than at the wavefunction level. We furthermore suggest that not all quantum states are consistent with qualia. If this is the case, the standard wavefunction collapse postulates of the Copenhagen interpretation will fail to select only those states which are consistent with qualia, and the Born-rule must be modified if wavefunction collapse is to generate the correct dynamical histories across time. This new model which includes qualia clearly demonstrates how non-linear and self-referential phenomena can occur, despite the linear, deterministic time-evolution of the wavefunction. We reject the notion that physical matter operates independently of qualia, and find that the main evidence for epiphenomenalism i.e. the causal closure of the underlying physical time-evolution, has failed to take into consideration fine-tuning of the microcausal degrees of freedom. We propose that the philosophical zombie argument is fine-tuned in the initial conditions, thus making philosophical zombies statistically unlikely if the fine-tuning is removed. We furthermore suggest the presence of fine-tuning can be used as a test for consciousness in the general case. This explains why some classical processes such as computer circuits may never be conscious; because they lack the capacity for fine-tuning when the dynamics is reversed.
