Decision making and learning while taking sequential risks. *Journal of Experimental Psychology: Learning, Memory, and Cognition, 34*(1), 167-185. **Target of replication.** We seek to replicate the a priori planned comparison which found a significantly stronger correlation between the ART and self-reported drug use in the sunny condition than in the cloudy condition (z=3.10, p=0.0019). **A priori replication criteria.** A successful replication would find that the learning process hinders the diagnosticity of the ART in identifying individuals at increased risk of using hazardous drugs. The subjects will be recruited from the masters programs at the Stockholm School of Economics (there are six masters programmes: international business, finance, business and management, economics, general management, accounting and financial management). As Pleskac (2008) had about the same fraction of men and women in the sample (38 men and 34 women) we will recruit about 50% women.
