Free Will's lack of Free Will

So, freedom right? The freedom to choose. Allegedly, we humans have the capacity for free will. All right, that's cool. So I can do what I would like right?

Well, not so fast. Even if you have the freedom to choose, you don't really have freedom in what you want to choose. You often make instantaneous knowledge of your preferences. You want to have ice cream or tacos, like Taylor Swift better than The Roots, prefer to write with pens or pencils? And so on.

These answers live before the question is asked. Like a Stern-Gerlach device measures the charge of an electron, depending on a lot of things prior to the question being asked, you know what your charge is on a given thing. Upon hearing the question, you reach into the part of yourself that has the answer and there it is.

Where is the free will? Sure, you got the choice to eat poop instead of rice, but is that 'free will' we are talking about really what matters? I think it may be more important that we realize the decision already made and act on it. Our brain is to be used in understanding what we can before making the next choice, and if you haven't learned not to eat poop, eat poop. Shouldn't take long right? That scientific experiment has pristine, golden results. Your brain is there to deal with the past information, but once you think A is better than B, your brain's job is done. There is no choice, no free will. Just realization.
