Blind spots in the search for happiness: Implicit attitudes and nonverbal leakage predict affective forecasting errors

We investigated implicit knowledge and affective forecasting, reasoning that although conscious evaluations are available to people when predicting their future emotional responses, nonconscious evaluations are not. However, these automatically-activated evaluations should contribute to in-the-moment emotional experiences, and thus they should account for misforecasts (i.e., discrepancies between affective forecasts and actual experiences). We conducted two studies to explore affective misforecasts, using food items as stimuli. In Study 1, participants' implicit attitudes (but not their explicit attitudes) predicted misforecasts of food enjoyment, supporting the role of nonconscious evaluations in affective forecasting errors. In Study 2, we examined participants' facial expressions (another index of nonconscious evaluation) upon the presentation of food items, and we found that these nonverbal behaviors predicted affective misforecasts as well. In sum, although nonconscious evaluations are unavailable when anticipating the future, they may contribute to one's in-the-moment experiences and thus serve as blind spots in affective forecasting.
