After taking a hiatus from my road biking due to other commitments and cold weather, I hooked it up to my trainer last weekend and went for a ride.
It was a much-needed break from all the lack of exercise and terrible eating I had been doing. So though it wasn’t exactly fun, it felt great.
As soon as I got off the bike, I also found that I suddenly had an aversion to snacks and fatty foods. Why should this be? I know that exercise has been shown to be an appetite suppressant, but is what’s going on here really just physiological, or could it also be psychological?
As I pondered my situation, I realized that what was pushing me to suddenly eat more healthfully was the desire to not destroy the benefit gained from exercise. I was, it seemed, experiencing loss aversion at work.
Could this be why dieting is so unsuccessful when not accompanied by exercise? Could it be that when a change in diet is the focal point of healthier living, that exercise feels like an additional sacrifice?
When exercise is the focal point, however, eating healthfully is a natural response based in our loss averse tendencies. I mean, you just burned all those calories. You’re not going to put them back on by eating that fatty cheeseburger, are you?

I’m embarrassed to admit it, simply because for the last decade or so I have tried so hard to reject the fast-food diet I had as a kid growing up in rural America. Still, however, there is a warm place in my heart for the McDonald’s Monopoly game.
One thing I notice now, though, that I didn’t notice then, is how McDonald’s plays on our irrationality to make this annual marketing campaign such a success. There are two elements, specifically, that it relies on.
“Threshold” Values
This is a term that I’m making up, perhaps only because I’m not aware of the official moniker. The idea, however, consistent with behavioral economics thinking, is that we have a tendency to over-value certain amounts because of their symbolic value. People play the Monopoly game not just because it is a fun complement to their dinner, but also because of the (very distant) possibility of winning that million dollar prize touted in all of the Monopoly game commercials.
A million dollars is a very powerful and motivating amount in our society. We imbue it with all kinds of meaning and importance that is totally undeserved when you consider how close it is in proximity to 999,999. For most middle-class Americans, to be a “millionaire” is to have reached the apex of financial success.
Money Illusion
A million dollars doesn’t buy what it used to. And it sure as hell won’t buy in twenty years what it would buy you today. McDonald’s recognizes this, but they also know that most Americans don’t, and so they don’t hesitate to reward the million dollar prizes in annuity payments of $50,000 over twenty years.
They are playing on what behavioral economists call money illusion – our tendency to value money in terms of nominal and not real (i.e., discounted for inflation) amounts.
For example, at an average rate of inflation of 3.5%, the $50,000/year that McDonald’s pays its winners would be worth (before taxes) about $735,000 in today’s dollars. After tax, it would probably be in the neighborhood of $500,000. (This is its “present value.”)
McDonald’s tactic here also takes for granted the idea that people don’t consider opportunity cost when thinking about how they spend and invest money. If we did, we would almost certainly poo-poo McDonald’s annuity payment approach and demand a bulk payment in year one.
For example, let’s say that McDonald’s paid out that $735,000 to its winners immediately, instead of promising a million dollars over twenty years. And let’s say that 50% is taken away in taxes, so you’re left with about $367,000. If you were able to invest that money for twenty years at a modest 7% rate of return, you’d end up with about $1.325 million (in nominal terms), significantly more than the $1 million they give away.
Note: Robert Shiller and George Akerlof provide a great overview of money illusion and the history of the idea in their book, “Animal Spirits.”
To tie this all together. Let’s imagine that, instead of the “Play the Monopology Game, Win a Million Dollars!” message that McDonald’s currently sends out, they said something like this…
“Play the Monopoly Game, Win Over $700,000! …Because even after taxes, your winnings can become well over a million dollars in twenty years by investing smartly!”
Now wouldn’t that be a hell of an ad campaign!?
It turns out that even medical doctors are subject to the whims of irrationality and the phenomena of behavioral economics.
This would come as no surprise to Nassim Taleb (whose next book I fear will not be very kind to the medical profession – http://www.fooledbyrandomness.com/notebook.htm), but is likely to be a bit disturbing to the rest of us who tend to be guilty of assigning god-like status to our physicians.
If you ever wondered whether pharma companies are effective at influencing the behavior of doctors, please read the linked article below.
The Ethical Taint of Post-It Notes — and the Power of a Company Policy « Lead Good
Nice little post here from the blog “Unbundling as a Pricing Strategy.” It’s a good example of applying choice architecture and libertarian paternalism to everyday choices that cary with them much grander consequences.
“When people see a 5 cent charge per bag they are more than likely to bring their own bags than if there were given a credit for each bag.”
I just finished Thaler and Sunstein’s Nudge. Though my enthusiasm faded a bit as the book wore on, I have to admit that the concept of choice architecture that they explore is one of the most exciting ideas that I’ve encountered in a long time. So exciting, in fact, that I would consider making a career of it (in some ways I already am).
Enthusiasm aside, as I finished the last chapter on “Objections” tonight, I was struck by one of the authors’ comments.
They discuss the objection that policymakers should always attempt to be neutral. Well, the premise of the book rests largely on the fact that many of us are choice architects, even though we may not realize it. We are involved in designing the environments in which people make decisions. Therefore we influence decisions, whether we like it or not. So we might as well be intentional in how we go about our design.
What struck me about the neutrality discussion was the assumption that neutrality somehow denotes innocence. For some reason, as a society we forgive neutrality and punish or reward intentionality (depending on how things turn out). So if I kill someone unintentionally – in a car accident, for example – I am treated differently than if I kill someone in a premeditated fashion. The first is likely to somehow be a result of negligence, while the second is a result of something much more insidious. In this way, they are different. Yet, both result in the same outcome.
Along the same lines, choice architects who drive us toward stupid decisions unintentionally are somehow innocent. Yet, those who drive us toward bad decisions intentionally are somehow evil because they game the system.
This seems a bit strange to me. Maybe it shouldn’t. But I would prefer a set of cultural norms that places slightly greater emphasis on personal awareness and responsibility.
If you drive, you drive safely. If you nudge, nudge intentionally.
