Free Will and Non-Computability

Is your sense of choice merely an illusion, or could there be something truly fundamental about your decisions? In today's episode of Mind Shift, Kate explores the frontiers of consciousness, diving deep into quantum mechanics and its provocative implications for human agency. The episode challenges mainstream neuroscience with ideas that blur the boundaries between physics and philosophy, pondering whether free will might be woven into the very fabric of reality.

Building on last episode’s mind-bending suggestion that consciousness and the flow of time might be quantum twins, today's discussion probes the heart of free will. Kate unpacks Roger Penrose’s arguments for non-computable elements in the brain, examines the quantum processes that might underpin our choices, and asks what would have to be true for genuine agency to exist—not just as a story we tell ourselves, but as a scientific possibility.

“There's a gap, a space for something beyond both randomness and computation,

is that gap...consciousness itself?” ~Kate

Today on Mind Shift:

·     Why most neuroscientists dismiss free will as a biological illusion, and the experiments they cite

·     The Benjamin Libet studies: What do they really prove about the timing of conscious decisions?

·     Penrose’s Gödelian argument: can humans recognize truths that computers cannot?

·     What non-computable processes are, and why Penrose thinks they’re essential to consciousness

·     Quantum state reduction (objective reduction) and its possible role in decision-making

·     The difference between standard quantum mechanics and the hypothesized OR collapse

·     Retro-causation: could quantum collapse allow decisions to influence the past, within superpositions?

·     Temporal nonlocality: how quantum processes might span time, giving agency to consciousness

·     Why randomness isn’t free will, and neither is determinism

·     The third option: non-computable choice

·     Critiques of Penrose’s view, dualism, misunderstanding of Gödel, and skepticism from physicists

·     How this idea puts consciousness not outside physics, but at its foundation

·     What ORCH OR could mean for AI, medicine, and the quest to understand ourselves

·     The scientific limits: what we know so far and what remains speculative
