Let me first show you an experimental paradigm that's used to demonstrate the synthesis of happiness among regular old folks. This isn't mine, it's a 50-year-old paradigm called the "free choice paradigm." It's very simple. You bring in, say, six objects, and you ask a subject to rank them from the most to the least liked. In this case, because this experiment uses them, these are Monet prints. Everybody ranks these Monet prints from the one they like the most to the one they like the least. Now we give you a choice: "We happen to have some extra prints in the closet. We're going to give you one as your prize to take home. We happen to have number three and number four," we tell the subject. This is a bit of a difficult choice, because neither one is preferred strongly to the other, but naturally, people tend to pick number three, because they liked it a little better than number four.
