I believe in a model similar to panpsychism. This makes sense to me as any system you entangle yourself within will have an effect on your will. If you are using a tool your brain will similarly behave differently due to the difference in machine that you then are. The complexity within our brains are like an engine of entropy and from its chaos arises a denser form of consciousness then that of smaller systems of energy exchange. People really like to assume their subconscious is just a different part of themselves, but instead it is all things that have a play in the decisions we make from our individual cells to gravitational pulls to zeta distributions in relative frequency of occurrence regarding anything that has ever happened.
