'Stumbling on Happiness,' by Daniel Gilbert
The Joy of Delusion
Review by SCOTT STOSSEL

"Teenagers get tattoos because they are confident that DEATH ROCKS will always be an appealing motto," he writes. "Smokers who have just finished a cigarette are confident for at least five minutes that they can quit and that their resolve will not diminish with the nicotine in their bloodstreams." For another, as Gilbert shows through a series of logic games and diagrams meant to dupe the reader (they worked on me), we misperceive reality — as philosophers since Kant have recognized — and then use those misperceptions to build a mistaken view of the future.

Events that we anticipate will give us joy make us less happy than we think; things that fill us with dread will make us less unhappy, for less long, than we anticipate. As evidence, Gilbert cites studies showing that a large majority of people who endure major trauma (wars, car accidents, rapes) in their lives will return successfully to their pre-trauma emotional state — and that many of them will report that they ended up happier than they were before the trauma. It's as though we're equipped with a hedonic thermostat that is constantly resetting us back to our emotional baseline.
