 The Many Labs project (Klein et al. 2014) coordinated 36 independent replications of 13 classic psychology phenomena (from 12 studies, that is, one study tested two effects), including anchoring, sunk cost bias and priming, amongst other well-known effects in psychology. In terms of matching statistical significance, the project demonstrated that 11 out of 13 effects could be successful replicated. It also showed great variation in many of the effect sizes across the 36 replications.
