Chris puts them right:-
[F]or this study to have any relevance to free will, there would have to be this conscious system (physical or not, it doesn't matter), separate from the unconscious one, that is sitting around getting input from the unconscious system and making its own decisions freely (whatever freely means in this context). You'd have to have a conscious mind that's watching the unconscious mind, and acting separately. If this is your model of how things work in the head, then you've got more problems than this data -- you've got a hundred years worth of data to contend with, along with some difficult logical and engineering problems.You might decide to read the whole thing. Or you might not - you may just find yourself reading it and only subsequently feel the need to justify the activity by reference to some sort of conscious decision making process.
If, however, you treat the conscious and unconscious minds as part of the same system, then any decision made by the latter are as free as decisions made by the former. That is, there's no reason to treat decisions made unconsciously as less free than decisions made consciously. Unless there's some property of conscious awareness that gives freedom to choices, but I have no idea what that property would be, and I don't think anyone else does either.
