This question refers to the findings of the famous experiments by Benjamin Libet. In his studies, Libet found that the readiness potential, a measure of brain activity indicating preparation for movement, began several seconds before participants were consciously aware of their decision to move. This suggests that the brain initiates the decision to move before the individual becomes consciously aware of it.
