John Tierney writes in the New York Times, Message in What We Buy, but Nobody’s Listening.

Suppose, during a date, you casually say, “The sugar maples in Harvard Yard were so beautiful every fall term.” Here’s what you’re signaling, as translated by Dr. Miller:

“My S.A.T. scores were sufficiently high (roughly 720 out of 800) that I could get admitted, so my I.Q. is above 135, and I had sufficient conscientiousness, emotional stability and intellectual openness to pass my classes. Plus, I can recognize a tree.”

Dr. Miller says that much of the pleasure we derive from products stems from the unconscious instinct that they will either enhance or signal our fitness by demonstrating intelligence or some of the Big Five personality traits: openness, conscientiousness, agreeableness, stability and extraversion.

In a series of experiments, Dr. Miller and other researchers found that people were more likely to expend money and effort on products and activities if they were first primed with photographs of the opposite sex or stories about dating.

After this priming, men were more willing to splurge on designer sunglasses, expensive watches and European vacations. Women became more willing to do volunteer work and perform other acts of conspicuous charity — a signal of high conscientiousness and agreeableness, like demonstrating your concern for third world farmers by spending extra for Starbuck’s “fair trade” coffee.

I talked about this a lot when I was running ProfileDoctor. Crass as it may seem to some, putting “I’m a Pete’s drinking, VW driving Trader Joes shopping kind of person” in your personal ad says much more about a person than “I’m caring, considerate and value family.” We are what we do, consume and pay attention to.
