Detailed Description of Method/Results Participants were recruited through Amazon's Mechanical Turk service, and from undergraduates at a small Midwestern liberal arts college. The correlation between mindfulness (MAAS) and resistance to sunk costs (RSC) was significant (r = 0.281, p < 0.01).

However, the RSC measure demonstrated low internal consistency (Cronbach's alpha = 0.416) and RSC scores were not well related to a second measure of sunk-costs (Sunk-cost fallacy, SCF), developed by Strough and colleagues (2014). While MAAS scores were significantly correlated with SFC scores (r = -0.143, p = 0.042), MAAS scores and RSC scores were more strongly related to whether an individual indicated a willingness to continue a course of action, independent of investment (see Further Details pdf).
