Stumbling on Happiness

Why can't we predict our own joy?

Humans are the only animal that thinks about the future, Daniel Gilbert says, and we use the gift to steer towards whatever we think will make us happy. The Harvard psychologist shows how often we steer wrong, and why the errors are so hard to spot from the inside.

The key ideas in Stumbling on Happiness

Imagination fills in

When you picture a future event, your brain quietly adds some details and leaves others out, and you don't notice either. Picture a move to the seaside and you see the sunsets and miss the long commute. Gilbert shows we then trust the picture as if it were a forecast.

Presentism

We imagine the future using how we feel now. Gilbert describes shoppers who had just eaten putting fewer unplanned items in their trolleys than hungry ones. Today's feelings leak into every forecast, so it's hard to imagine wanting tomorrow what we don't want right now.

The psychological immune system

After bad news, the mind goes looking for a kinder way to see it. The job we didn't get starts to look like a bad fit. It works well, but it works out of sight, so we don't count on it and overestimate how long the pain will last.

Ask someone who's there

Gilbert's fix is to use a surrogate. To know how something will feel, ask people living it now, instead of imagining it, because their reports beat our forecasts. We resist, he says, because we think we're more unusual than we are, so their experience can't apply to us.

Lines worth underlining

  1. Forecasting

    Humans can imagine the future, but we're bad at guessing how we'll feel when we get there.

  2. Filling in

    When we picture the future, the mind quietly fills in details that turn out to be wrong.

  3. Presentism

    We imagine tomorrow's feelings using today's mood, like shopping for food when hungry.

  4. Bouncing back

    Bad news hurts less, and for less time, than we expect, because the mind finds ways to cope.

  5. No way back

    People liked photos they couldn't swap more than ones they could still exchange.

A story from the book

The drummer the Beatles sacked

In 1962 the Beatles replaced their drummer, Pete Best, with Ringo Starr, just before they became famous. Gilbert quotes Best, decades later, saying he's happier than he would have been with the Beatles. Most of us assume that's a brave face. Gilbert suggests he may simply mean it.

Hot take · true or myth?

Being able to change your mind after a choice makes you happier with it.

Myth. In one of Gilbert's studies, students who could swap the photograph they'd chosen liked it less than students whose choice was final. While the door stays open, the mind doesn't settle.

One thing to try

Find a surrogate

Before your next big decision, like a new job or a move, find someone who did the same thing a few months ago. Ask them how an ordinary Tuesday feels, rather than what they think of the decision. Give their answer more weight than your own daydream.
