Affective forecasting

Daniel Gilbert & Timothy Wilson, 2003

We are confident weather-forecasters of our own hearts, and we are usually wrong. Gilbert and Wilson showed that people systematically overestimate how intense and how lasting their future feelings will be — sure that the promotion will elate us or the loss will undo us for far longer than either does. The error has a shape: we focus on the change and forget how much else will fill the days around it.

Working definition

Forecasts of future affect err through immune neglect, focalism, and impact bias; we are poor weather-forecasters of our own hearts.

Where Vela uses this

Affective forecasting tempers Vela's reading of desire and dread alike — it is a useful corrective to the stories we tell about what will finally make us happy or destroy us. It pairs with cognitive appraisal (the evaluations that drive present feeling) and informs how the corpus treats anticipation. Vela cites it for the overconfident reader who trusts their own predictions about future feeling.

Origin & lineage

Gilbert & Wilson (2003); Gilbert's *Stumbling on Happiness* (2006) → mechanisms named as impact bias, focalism, and immune neglect → ongoing work on when forecasts are accurate.

Honest framing

The bias is robust on average but not universal — some forecasts are well-calibrated, and replication has refined which. Vela uses it as a caution about a general tendency, not a verdict on any one person's predictions.
