By his premise, I mean his statement on free will:
What is it that draws us in these two conflicting directions? The philosopher Shaun Nichols and I thought that people might be drawn toward one view by their capacity for abstract, theoretical reasoning, while simultaneously being drawn in the opposite direction by their more immediate emotional reactions. It is as though their capacity for abstract reasoning tells them, “This person was completely determined and therefore cannot be held responsible,” while their capacity for immediate emotional reaction keeps screaming, “But he did such a horrible thing! Surely, he is responsible for it.”
I think what draws us so strongly to believe that we have free will is that our experience tells us that we do. We make decisions all the time, and they are apparently free. The conflict comes in when we look at our brains which are constructed of material that experience tells us reacts in a determinsitic way to various events.
The example question does not seem to me to be directly on the question of free will but rather on the question of moral responsibility. The example question immediately becomes conflated with questions about a desire for justice that will be more strongly brought out in an emotional situation than in a purely intellectual sitation.
In the given example, they've already answered the free will question. They have preset the situation so that there is no free will. So, it doesn't look to me like the property they wish to test is the property that they are actually testing.
