Two studies investigated the hypothesis that individuals using the cognitive strategy of defensive pessimism will perform better and feel better when allowed to play through possible outcomes and reflect on their progress. In contrast, individuals using an optimistic strategy will perform more poorly and feel worse when they are encouraged or required to reflect on themselves and their goals. A laboratory experiment and a study using experience-sampling methodology (ESM) revealed this pattern for self-reported mood, appraisal of tasks, and progress toward goals; objective performance; and a physiological measure, though the interaction was not always statistically significant
Norem et al. (Fri,) studied this question.
