Die hard rational choice social scientists are often puzzled when they see people making less than optimal decisions. For example, it is hard to explain why people choose to pay the cost of punishment and make themselves worse off just so that they can punish someone who acted unfair or against the rules. I came across an example of this in yesterday’s Washington Post when a reporter published a story about a little known short cut near the Dulles Airport. According to the reporter, drivers normally sit in traffic, moving slowly, on a toll road as they drove passed the airport, but they could avoid the traffic and save time and money by taking the public access road through the airport. The only problem is that the public access road is only meant for airport traffic. It is against the “rules” to drive on it unless you are utilizing the airport’s services or are have a passenger with you during rush hour. People have found creative ways around these rules, like buying a cup of coffee from the sole gas station in the airport or driving with a blow up doll in the passenger seat. However, these methods are not exactly seen as legitimate ways to get around the rules. The "right" thing to do is to stay on the toll road and not cut through unfairly through the airport road.
