The impact bias, a form of which is the durability bias, in affective forecasting, is the tendency for people to overestimate the length or the intensity of future feeling states.
In other words, people seem to think that if disaster strikes it will take longer to recover emotionally than it actually does. Conversely, if a happy event occurs, people overestimate how long they will emotionally benefit from it.
Daniel Gilbert and Timothy Wilson first identified this bias, and proposed the name change to refer more broadly to all forms of emotional "impact", including durability as well as intensity, and the rate of ascension and descension, etc. Daniel Kahneman has also contributed research on this cognitive bias.
A possible explanation for the impact bias is given by the theory of cognitive dissonance: most times people are very good at reducing cognitive dissonance, but, since it happens unconsciously, do not know it. Another explanation is 'focalism', the tendency in affective forecasting to neglect the influence of other activities in minimizing one event's impact.
