A Characteristic Difference [1]

DANIEL KAHNEMAN:  We're at the nub of the question. You come from philosophy, so there are certain things that are of interest to you. You want to convey two things at once: that the question is exciting, and that you have something new to say about it. It is true that I, as a psychologist, would come to the same question and conclude that it's an impossible question. Those are two impossible questions, and I certainly would not expect people to answer them in any way that is coherent.                                  

My first assumption, coming to it as a psychologist, is that there is no coherence. You agree with me that there is no coherence. What makes it exciting from the point of view of philosophy is that there is no coherence. Whereas, as a psychologist, I take it for granted that there is no coherence, so it's less exciting. That could be one of the differences.               

JOSHUA KNOBE:  That's really helpful. The thing we showed is not just that it is incoherent but along which dimension it is incoherent. It seems like there was evidence already that there's something pulling us towards one side and something pulling us to the other side, and we want to know which thing is pulling us towards one side or the other. We suggested that it's this difference between abstract thinking and concrete thinking....
