Concept
Surrogation
Surrogation is Gilbert's remedy for the impact bias: instead of imagining how a future situation will feel, ask someone who is already living it. A stranger's report of the actual experience predicts your future feeling better than your own detailed imagining, and it costs one conversation.
People resist surrogation because they believe their own case is special and their imagination is better informed than a stranger's experience. The research says the opposite, repeatedly: given a choice between a detailed description of a situation and a one-line report from someone in it, the report predicts feelings better, and people who are shown this still prefer the description. The reason is the imagination's mechanics, presentism and omission, which no amount of detail fixes. The practice is simple. Find a person a year into the job, the city, the degree, the marriage you are forecasting, and ask about ordinary days rather than whether it was worth it: what a Wednesday is like, what they did not expect, what they miss. Then compare with what you imagined; the gap is the bias, measured. It is the same move as the Mom Test for founders: ask about the real past, not the imagined future.
A real-life example
Before accepting a regional role in Dubai, a manager messages a former colleague already there and asks about a normal Wednesday. The eleven-hour days and the monthly flight home go into her plan, and the first six months hold no surprises.
How to use it
- 1Before a big forecast, find someone a year into the same outcome.
- 2Ask about ordinary days and what they did not expect, not whether it was worth it.
- 3Write down the gap between their answer and what you imagined, and plan for it.
