Lunch Talk: Moral Tribes (Joshua Greene gives a talk at Google)

Note how his experiments show the relationship b/w physical distance and psychological distance. A similar effect happens when inventors are trying to explain their ideas to investors. I also like his analogy between Kahneman's System 1 vs System 2 on one the hand, and point-and-shoot and SLR cameras on the other: the former is set on automatic, while the latter on manual.
