something if it is expensive than if it is cheap.
Buying wine is an exercise that combines flavor, smell, and other physical attributes with an array of difficult-to-measure qualities—from how well it projects our self-image to whether it brings forth pleasant memories of a European vacation. Americans will pay more for a French wine than an Argentine wine of similar quality, the same grape varietal, and the same age. Simply stamping “Product of Italy” on the label can raise the price of a bottle by more than 50 percent.
Economists will tell you that, other things being equal, people will always prefer the cheaper option. But drinkers like a bottle of wine more if they are told it cost ninety dollars a bottle than if they are told it cost ten. Belief that the wine is more expensive turns on the neurons in the medial orbitofrontal cortex, an area of the brain associated with pleasure feelings.
Wine without a price tag doesn’t have this effect. In 2008, American food and wine critics teamed up with a statistician from Yale and a couple of Swedish economists to study the results of thousands of blind tastings of wines ranging from $1.65 to $150 a bottle. They found that when they can’t see the price tag, people prefer cheaper wine to pricier bottles. Experts’ tastes did move in the proper direction: they favored finer, more expensive wines. But the bias was almost imperceptible. A wine that cost ten times more than another was ranked by experts only seven points higher on a scale of one to one hundred.
Sometimes people pay stratospheric prices for humdrum items because doing so proves that they can. As the price of oil soared to around $150 a barrel in the summer of 2008, Saeed Khouri, a twenty-five-year-old businessman from Abu Dhabi, made it into Guinness World Records for having bought the most expensive license plate ever. Khouri paid $14 million for the “1” tag in a national license plate auction that drew Rolls and Bentley owners from around the kingdom. The number one is, to be sure, a nice digit to have stamped on a piece of plastic attached to the front and back of a car. But it is hard to argue that the number alone merits a premium of $13,999,905 over the standard fee for a regular license plate.
This behavior is surprisingly common, however. Paying high prices for pointless trinkets is just an expensive way to show off. In his famous Theory of the Leisure Class, the nineteenth-century American social theorist Thorstein Veblen argued that the rich engaged in what he dubbed “conspicuous consumption” to signal their power and superiority to those around them. In the 1970s, the French sociologist Pierre Bourdieu wrote that aesthetic choices served as social markers for those in power to signal their superiority and set themselves apart from inferior groups. Anybody can buy stocks. Oligarchs, emirs, and hedge-fund managers can pay $106.5 million for Picasso’s Nu au Plateau de Sculpteur, which sold in only eight minutes and six seconds at an auction in New York in May of 2010. Had Mr. Khouri paid ninety-five dollars for a license plate, he could have been anybody.
Over the last three decades, evolutionary biologists and psychologists picked up on Veblen’s and Bourdieu’s ideas and gave them a twist. The point of spending huge sums on useless baubles is not merely to project an abstract notion of power. It serves to signal one’s fitness to potential mates. Wasteful spending on pointless luxury is not to be frowned upon; it is an essential tool to help our genes survive into the next generation. Sexual selection puts an enormous value on costly, inane displays of resources. What else is the peacock’s tail but a marker of fitness aimed at the peahens on the mating market? It is a statement that the bird is fit enough to expend an inordinate amount of energy on a spray of pointless color.
