If people avoid alternatives they dislike, a negative evaluative bias emerges because errorsof under-evaluation are unlikely to be corrected. Prior work that analyzed this mechanismhas shown that when the social environment exposes people to avoided alternatives (i.e. itmakes them resample them), then evaluations can become systematically more positive. In this paper, we clarify the conditions under which this happens. By analyzing a simple learning model, we show that whether additional exposures induced by the social environment lead to more positive or more negative evaluations depends on how prior evaluations and the social environment interact in driving resampling. We apply these …
