According to Morsella's framework, the "free will" that people typically attribute to their conscious mind -- the idea that our consciousness, as a “decider,” guides us to a course of action -- does not exist. Instead, consciousness only relays information to control "voluntary" action, or goal-oriented movement involving the skeletal muscle system.

Compare consciousness to the Internet, Morsella suggested. The Internet can be used to buy books, reserve a hotel room and complete thousands of other tasks. Taken at face value, it would seem incredibly powerful. But, in actuality, a person in front of a laptop or clicking away on a smartphone is running the show -- the Internet is just being made to perform the same basic process, without any free will of its own.
