Mindfulness and decision-making: Sunk-costs or escalation of commitment?

Mindfulness is related to a number of positive health outcomes, such as decreased stress, anxiety and improved physical functioning. Recent studies have also identified a range cognitive benefits of mindfulness, including recent studies demonstrating that higher trait mindfulness and brief mindfulness inductions are associated with improved decision-making, and specifically to resistance to the influence of sunk-costs, where higher mindfulness is associated with increased willingness to discontinue a costly, but disadvantageous, course of action. However, some previous studies examining mindfulness and the sunk-cost bias have methodological limitations which make it difficult to determine if mindfulness is specifically related to sensitivity to the sunk-cost bias, or rather than to a general willingness to continue an unprofitable course of action (independent of the level of prior investment). The present study extends previous work by replicating the finding that trait mindfulness is positively related to resistance to the effects of sunk-costs, and also demonstrates that mindfulness is related to reduced escalation of commitment, an individual’s willingness to continue their commitment to a unprofitable course of action through the further investment of resources or time. Overall, trait mindfulness was most consistently related to reduced escalation of commitment, whereas the relationship between trait mindfulness and resistance to the effects of sunk-costs were less consistently observed
