John Searle criticizes Libet experiment that attempts to prove that Readiness Potential brings the act of pushing the button. This can be understood from the following quote by Searle:
The cases in question are all cases where the subject has already made up his mind to eventually perform a course of action, and the brain has an increased activity prior to his awareness of a conscious decision to physically perform it; but the presence of the readiness potential does not constitute a causally sufficient condition for the performance of the action. It could be the case that a person would have been inclined to push a button, that the brain then undertook the activity called readiness potential, and that the person would not push the button. Readiness potential in the brain is not a condition that is sufficient to cause the act. It is associated with the act but does not determine it.
