Just because you can predict what simple decision I will make before I am aware of it consciously, does not imply I don't have free will. All it says is that my conscious awareness of some other part of my brain making the decision is delayed by x milliseconds i.e. we are not making decisions in the upper layers of consciousness, but below it.
When you think about it, it is what I would expect. Your awareness is the product of nerves firing, so they have to fire before it can be reflected in your consciousness. If you decide to recall some information, the neurons storing that information have to be activated (they have to fire). If you can create a device (and we have) to detect those nerves as they are firing you will know what person is trying to recall before (by some miniscule lead time) they are aware of it.
