Has this study been replicated?

The atlas records 3 replications of this study. Recorded outcomes: 3 failed.

The duality of poverty: a replication of Mani et al. (2013) in Colombia, González-Arango et al. (2021). Outcome recorded: failed. As opposed to Mani et al. (Science 342:976–980, 2013), we did not find that scarcity taxed individuals' mental bandwidth, neither their cognitive nor executive functions. View paper
Empirical audit and review and an assessment of evidentiary value in research on the psychological consequences of scarcity, O'Donnell et al. (2021). Outcome recorded: failed. Contrary to prior results (Mani et al., 2013), there was no robust interaction between income and condition (F(1,224) = 0.17, p = .678). View paper
Eleven years of student replication projects provide evidence on the correlates of replicability in psychology, Boyce et al. (2023). Outcome recorded: failed. Subjective replication success rating = 0 (failed). The replication report rated each sub-outcome on a 0-1 scale; the row is recorded as failed only when all sub-outcomes equal 0, successful only when all equal 1, and mixed for any value strictly between.
