If you lay out five different objects that have been rated as equally appealing by test groups, they will pick one and say they picked it because they liked it the best, pointing out some feature of the object that made them pick it. But in actuality they pick the one on the far right 80% of the time.

So you have to ask: in all of our "choices" are the reasons we think we have the actual reasons?

But then, what do you call our capacity to resist our basic urges at times, and the effect our thoughts can have on our actions?

I would replace free will with "will", the urge to follow a set of beliefs rather than our "lower" (for lack of a better word) urges.

I follow Sartre on this one, and say that yes there is free will and that we can know this through angst and anxiety.
I don't understand this...
