Over the past decade, an abundance of psychology research has shown that experiences bring people more happiness than do possessions. The idea that experiential purchases are more satisfying than material purchases has long been the domain of Cornell psychology professor Thomas Gilovich. Since 2003, he has been trying to figure out exactly how and why experiential purchases are so much better than material purchases. In the journal Psychological Science last month, Gilovich and Killingsworth, along with Cornell doctoral candidate Amit Kumar, expanded on the current understanding that spending money on experiences "provide[s] more enduring happiness." They looked specifically at anticipation as a driver of that happiness; whether the benefit of spending money on an experience accrues before the purchase has been made, in addition to after. And, yes, it does.

Essentially, when you can't live in a moment, they say, it's best to live in anticipation of an experience. Experiential purchases like trips, concerts, movies, et cetera, tend to trump material purchases because the utility of buying anything really starts accruing before you buy it.

Waiting for an experience apparently elicits more happiness and excitement than waiting for a material good (and more "pleasantness" too—an eerie metric). By contrast, waiting for a possession is more likely fraught with impatience than anticipation. "You can think about waiting for a delicious meal at a nice restaurant or looking forward to a vacation," Kumar told me, "and how different that feels from waiting for, say, your pre-ordered iPhone to arrive. Or when the two-day shipping on Amazon Prime doesn’t seem fast enough."

Gilovich's prior work has shown that experiences tend to make people happier because they are less likely to measure the value of their experiences by comparing them to those of others. For example, Gilbert and company note in their new paper, many people are unsure if they would rather have a high salary that is lower than that of their peers, or a lower salary that is higher than that of their peers. With an experiential good like vacation, that dilemma doesn't hold. Would you rather have two weeks of vacation when your peers only get one? Or four weeks when your peers get eight? People choose four weeks with little hesitation.

Experiential purchases are also more associated with identity, connection, and social behavior. Looking back on purchases made, experiences make people happier than do possessions. It's kind of counter to the logic that if you pay for an experience, like a vacation, it will be over and gone; but if you buy a tangible thing, a couch, at least you'll have it for a long time. Actually most of us have a pretty intense capacity for tolerance, or hedonic adaptation, where we stop appreciating things to which we're constantly exposed. iPhones, clothes, couches, et cetera, just become background. They deteriorate or become obsolete. It's the fleetingness of experiential purchases that endears us to them. Either they're not around long enough to become imperfect, or they are imperfect, but our memories and stories of them get sweet with time. Even a bad experience becomes a good story.
