Consider this:
When you make a descision based upon previous knowlege, does that constitute a free choice? Given the exact same circumstances, would you not make the same descision?
If the answer to the latter is, "Yes," then you have no free will. As noted in the article, a choice where you know what to expect and are making descisions based upon that your subconcious can do that for you; in short, you are not necessarily conscious.
If, however, you make a descision based on the assumption that every situation is new (which it technically is), then you will make descisions based upon the present rather than the past, which the subconcious is incapable of.
To truly have free will is to make descisions not based upon past knowlege, but to make a descision based upon the present. That is, effects of past experiences are not necessarily going to be the same as similar present experences.
Only when you understand and live by that will you be truly conscious and truly have free will.
