Dr. Miller's New Book: "Spent: Sex, Evolution, and Consumer Behavior"
"Why does a diploma from Harvard cost $100,000 more than a similar piece of paper from City College? Why might a BMW cost $25,000 more than a Subaru WRX with equally fast acceleration? Why do “sophisticated” consumers demand 16-gigabyte iPhones and “fair trade” coffee from Starbucks?
If you ask market researchers or advertising executives, you might hear about the difference between “rational” and “emotional” buying decisions, or about products falling into categories like “hedonic” or “utilitarian” or “positional.” But Geoffrey Miller, an evolutionary psychologist at the University of New Mexico, says that even the slickest minds on Madison Avenue are still in the prescientific dark ages.
“Evolution is good at getting us to avoid death, desperation and celibacy, but it’s not that good at getting us to feel happy,” he says, calling our desire to impress strangers a quirky evolutionary byproduct of a smaller social world.
"If marketers (or their customers) understood biologists’ new calculations about animals’ “costly signaling,” Dr. Miller says, they’d see that Harvard diplomas and iPhones send the same kind of signal as the ornate tail of a peacock."
“We evolved as social primates who hardly ever encountered strangers in prehistory,” Dr. Miller says. “So we instinctively treat all strangers as if they’re potential mates or friends or enemies. But your happiness and survival today don’t depend on your relationships with strangers. It doesn’t matter whether you get a nanosecond of deference from a shopkeeper or a stranger in an airport.”
