Now what I want to see is if M1 neurons begin to show increased activity before someone thinks about getting up to go pee, but decides to hold it in. Because if so, it’s pretty clear that the decision making process simply involves motor neurons readying themselves in case they’re needed. But if they don’t, then it means the motor cortex is contributing to the decision making process, and that’s an actually informative result.












And what we’re doing right now is good science. We’re operationalising our variables and making testable predictions, deciding what the possible results could mean before we conduct the experiment and see them.
Saying “Neuron activity before a decision is made disproves free will” is bad science, because “free will” is being implicitly operationalised in a very opinionated way, and it’s not exactly clear what the experimenter thinks a null hypothesis result would look like.
I don’t think neuroscience can tell us whether free will exists, because “free will” is too difficult to operationalise in a way everyone would agree with. For example, many people think if our actions are predetermined based on our environment, it means no free will. But I think if our actions are random, that’s not free will, and predetermined actions would make Me feel much freer. I want to know that My mind behaves consistently, that makes Me feel in control. Many disagree. This disagreement can’t be resolved with science.
