Has this study been replicated?

The atlas records 1 replication and 1 reproduction of this study. Recorded outcomes: 1 successful, 1 mixed. The earliest on record is from 2026.

SCORE new data replication of Goeree (2011), Parsons et al. (2026). Outcome recorded: successful. This replication attempt was extremely successful. This is perhaps not surprising, since if participants vote with their signal (i.e. guess jar 1 if they draw a red ball and guess jar 2 if they draw a blue ball), then the odds of selecting jar 1 when the majority of group membersdrew a red ball mechanically decline as the decision threshold increases from 5 to 7 to 9. Outcome read from OSF report.

Reproduction (with author data): Goeree et al. (2011, Econometrica), Chen et al. (2020). OSF. Outcome recorded: computationally reproducible, robustness not checked. Computational: I have successfully replicated the focal test. Outcome read from Computational: Reproduction result heading. View paper
