Who Thought Your Last Thought? | A Mind Experiment
Who thought your last thought? Late at night, an angry reply can feel like the only answer. This short follows an unsent message, Benjamin Libet’s 1983 experiment, and the learned grooves that can turn a thought into action. The full film: Who Thought Your Last Thought? | A Mind Experiment https://www.youtube.com/watch?v=b12-KIpRmYo This short does not claim that every decision is predetermined. Libet’s experiment concerned small, voluntary movements. The real question is what we do once we notice an urge.
