Last week I attended a lecture by Paul Zak, a neuro-economist from Claremont Graduate University, at the the Mind Science Foundation. He has studied how our behaviors are affected by the presence in our brains of a chemical called oxytocin, which can affect how generous we are. The more oxytocin you have have, the more generous and empathic (or sympathetic) you are. So he calls oxytocin "the moral molecule." It helps us identify with others and understand their feelings and situatons. Oxytocin can also increase when people trust you or are generous to you.
What does this have to do with Adam Smith? He wrote a book called The Theory of Moral Sentiments. One point he made there was that we are able to sympathize with other people by trying imagine what they are going through. This is directly related to oxytocin. Last September I had a post on this called Science Proves That Adam Smith Was Right Over 200 Years Ago (sort of). That will provide you with more details.
Where does Bart Simpson come in? Professor Zak showed a video clip from the "The Simpsons" that illustrated sympathy, a concept that Adam Smith wrote about in the above mentioned book. To watch a lecture by professor Zak (very similar to the one he did here in San Antonio), go to The Moral Molecule. The Bart Simpson clip starts at the 7:40 mark. Bart's mom tells him to look at his sister and try to feel what she feels. Exactly the kind of thing Adam Smith talked about.
Oxytocin also facilitates trust. Economies need trust because not everything can be put into a law, a contract or be monitored. Your boss can't watch you every second to make sure you don't slack off on the job. We trust banks and our pension funds not to take the money and blow it all in Vegas. We trust our government officials not to accept bribes. Yes, we have rules and regulations against these things. But if we had to have a rule for everything and if everyone was being watched constantly, it would be too costly to our economy. Trust helps quite a bit.
Here are two articles about professor Zak's lecture from the San Antonio Express-News:
