For many decisions, going with your gut outperforms lengthy analysis
Over-explaining reasons for a preference can actually detgrade the quality of affective predictions.
Why it works
Wilson and Schooler’s "verbal overshadowing" effect shows that asking people to analyze their reasons for preferring something can degrade the quality of their preferences by shifting from intuitive affective processing to analytical processing that poorly captures the affective signal. Gilbert cites this as evidence that in preference-based decisions, the gut has information that verbal analysis doesn’t surface reliably.
How to do it
- For preference decisions (where to live, which option feels right), spend time experiencing each option before analyzing.
- Write down your gut reaction immediately, before reasoning about it.
- Use analysis to check for major factual errors or values mismatches — not to override affect-based signals.
Evidence
Wilson & Schooler (1991) showed that people who analyzed their reasons for preferring jams or college courses ended up with choices that agreed less with expert opinion than people who did not analyze their reasons. Replications have been mixed; the effect is real in some contexts and absent in others. In their studies, students who analyzed why they preferred certain strawberry jams, or certain college courses, made choices that agreed less with expert ratings than students who did not; the authors suggest that analyzing reasons focuses attention on criteria that are easy to put into words but not optimal. (observational)
Verbal overshadowing has proven difficult to replicate consistently and may be specific to domains where affect is the relevant signal (aesthetics, interpersonal fit) rather than to analytical decisions. Do not use this as a license to avoid thinking.

Common mistake
Using "go with your gut" as justification for avoiding the analysis that would reveal a decision’s actual consequences — the scope is preference and affective fit, not risk assessment or factual accuracy.

More practices for Affect Forecasting: Why You Mispredicted How You’d Feel
- Ask people who’ve been there instead of imagining it
Other people’s actual experiences predict your future feelings more accurately than your own imagination.
- Identify the other things that will also be true of your future life
Focalism is the tendency to focus so intensely on one future event that you neglect everything else that will also be true of your life — which makes that event seem bigger than it will actually feel.
- Expect to adapt more than you think you will
Your psychological immune system will make most setbacks feel more tolerable than you currently predict.
- Plan for hedonic adaptation in your goals
The happiness boost from achieving a goal fades faster than you expect — design goals with this in mind.
- The experience effect: rate how it feels now, not later
The experience effect is the gap between how something actually felt as you lived it and the story memory keeps afterward — memory is the unreliable one.
- Calibrate expectations for how long novelty will sustain motivation
New projects and environments produce an initial motivational burst that reliably fades — plan for this.
