I think the interesting part that relates to this experiment is that it's not worth it to the brain to expend a considerable amount of energy in honing the precision of deciding which candy bar to eat, which even if there's a preference is not extremely significant. What I'd be interested in seeing is a similar study where the subjects are presented with potentially life altering choices whose outcomes are unclear and see if the brain kicks in with extra processing power since it knows that the extra precision could make or break the lasting repercussions of the decisions. Not sure not only how you'd measure this but also whether it's possible to do such a study in an ethical way, but it would be interesting!
