More than intuitive , man has a need to survive. it is more than instinctive, it is innate. To survive he needs to be able to make agreements that are honest. He needs to have a moral standard that others understand and accept. If there are others within his circle of associates who accept these tenets then he is better able to make free will decisions. I don't think that the experiment involves activities which reflect real world situations, brain patterns aside. That's just me talking.
