In her Ted talk, Chang explains the methodology of how you pick between two options. She says that between the two choices one has to be greater, lesser, or equal to the other in value. If the two choices happen to be equal a fourth option arises: being “on a par.” This means that at the point when the pros and cons of both choices equal one another, and thus the choices are equal, free will can’t totally determine what option one should pick. Free will appears somewhat as an illusion. On a par means that one alternative isn’t better than another, which is why the choice becomes hard. So the choice one ends up making tells a lot about that individual’s characteristics, motives, and purposes, etc.. But because we learn all of this about ourselves, part of Kane’s self-forming theory has to apply at some point. So even if it seems like you have free will, and when you actually do have free will, a choice shouldn’t be made lightly because it defines your personality.
