The Consciousness Test That Would Change Everything

An envisioned consciousness test involves a machine predicting an individual's subjective experience in real-time based on a mathematical theory of consciousness, which the individual then attempts to falsify or confirm.

• Test consciousness theories by having a machine predict subjective experience, which individuals then verify.

• Theory validation mirrors physics: consistent predictions build confidence, even for unobservable phenomena.

• A working consciousness theory would allow predictions about coma patients and machine consciousness, fostering new research.

A groundbreaking experiment is proposed where a mathematical theory of consciousness, like Giulio Tononi's, is fed neural data from an individual to predict their subjective experiences. The individual then verifies or falsifies these predictions, allowing for the empirical testing and potential validation or refutation of consciousness theories. This approach, similar to how general relativity was validated, could extend predictions to coma patients and machine consciousness.

Envisioning the Consciousness Test

• 00:00:00 An experiment is envisioned to test theories of consciousness using a machine that processes real-time neural data from an individual. This machine would apply a mathematical theory of consciousness to predict the individual's subjective awareness, such as seeing a water bottle or feeling their heartbeat. The individual then internally verifies if the prediction matches their actual conscious experience, thus directly testing the theory's accuracy regarding subjective awareness rather than just neural correlates.

Validating Scientific Theories

• 00:02:03 The process of validating a consciousness theory is likened to how general relativity was established, where repeated accurate predictions lead to confidence, even for untestable phenomena like black holes. A scientific theory is accepted if its predictions consistently hold true across various tests, even if it cannot be definitively proven absolutely correct. Conversely, persistent incorrect predictions compel the development of alternative theories, much like the century-long, yet unsuccessful, attempts to disprove general relativity.

Implications of a Verified Theory

• 00:04:50 A validated theory of consciousness, one that consistently and correctly predicts subjective experience, would have profound implications, extending its predictions to unresponsive coma patients and the potential for machine consciousness. Such a theory would compel those who disagree with its broader implications to develop alternative mathematical frameworks that accurately predict subjective experience. This rigorous, empirical approach moves beyond simply dismissing consciousness as 'bullshit'.

Distinguishing Subjective Experience

• 00:07:48 The proposed test specifically defines consciousness as subjective experience, differentiating it from mere information processing or stored memories within the brain. The challenge for any theory is not just to identify what information is in the brain, but precisely which specific subset of that information an individual is consciously aware of at any given moment. A theory fails if it predicts awareness of details that are unconsciously processed or not part of the current subjective experience.
