The current research sheds new light on how individuals can best use the consideration of future outcomes as a self-control strategy to enhance their likelihood of goal attainment. Across three studies, the authors find that the effectiveness of positively versus negatively valenced outcome elaboration is dependent upon the construal level at which the potential outcomes are considered. This research demonstrates that positive outcome elaboration is more effective when it is abstract, whereas negative outcome elaboration is more effective when it is concrete. Moreover, the authors explore the process underlying these effects and demonstrate that the increased effectiveness of matching the outcomes’ valence and construal level is due to outcome elaboration fluency, as increased ease of generating outcomes that are positive and abstract or negative and concrete promotes more effective self-control.
