Headline result: \"forcing subjects to decide quickly increases contributions, whereas instructing them to reflect and forcing them to decide slowly decreases contributions\". Conclusion: \"intuition supports cooperation in social dilemmas, and that reflection can undermine these cooperative impulses\".\n- Original sample sizes are not in the stored abstract, so I don't state them.\n\n**The replication setup**\n- Task: \"In an anonymous 4-person economic game, participants contributed more money to a common project (i.e., cooperated) when required to decide quickly than when forced to delay their decision\". Manipulation: \"participants were either required to decide how much to contribute to the group within 10 s (time-pressure condition/intuitive decision making), or they were asked to wait at least 10 s before deciding on their contribution (forced-delay condition/reflection)\".\n- Design: \"combining 21 separate, preregistered replications of the critical conditions from Study 7 of the original article\". \"The protocol required testing of at least 75 participants in each of the two conditions\". \"A total of 21 laboratories contributed data from a grand total of 3,596 participants\".\n\n**Effect sizes (metric: contribution as a percentage of the maximum, time pressure minus forced delay)**\n- Original, re-analyzed intent-to-treat: \"An intent-to-treat analysis of data from the original study showed an 8.6 [95% CI: −1.84, 19.00] percentage point difference\".\n- RRR, intent-to-treat (the primary preregistered analysis): \"Across all participants, the meta-analytic effect size in the RRR was −0.37 percentage points [95% CI: −2.60, 1.86], a value smaller than observed in the original data and close to zero\". \"The observed effects ranged from −9.36 to 7.87\" across labs.\n- Compliant-only (how the original was analyzed): \"the meta-analytic difference between conditions was 10.37 percentage points compared with a 15.31 percentage point difference for the same analysis in the original study\". My arithmetic: 10.37 / 15.31 = 67.7% of the original difference.\n- Why the two analyses disagree: compliance was very uneven, \"34.1% and 92.5% compliance in the time-pressure and forced-delay conditions respectively\". Recomputed: 100 - 34.1 = 65.9% of time-pressure participants and 100 - 92.5 = 7.5% of forced-delay participants missed their time limit, matching the abstract's figures.\n- Authors' reading: the pattern is \"consistent with the presence of selection biases and the absence of a causal effect of time pressure on cooperation\".\n\n**Reading it.** Supported: in a 21-lab, 3,596-person preregistered replication of Study 7, assigning people to decide within 10 seconds did not raise contributions; the intent-to-treat estimate is about zero, with a CI that excludes the original 8.6-point point estimate. Not supported: that time pressure causally increases cooperation in this one-shot public goods game. The compliant-only gap (10.37 points) survives, but because two-thirds of the time-pressure group dropped out of that comparison, it can reflect who manages to answer fast rather than an effect of being rushed. Limits: this RRR tested only Study 7 (college students, lab setting), not the other nine studies in the original paper, and I did not recompute the meta-analytic estimates themselves, which come from lab-level data on OSF.","topics":["economics"],"evidence":[{"end":564,"start":521,"source_id":"MED:22996558","doc_sha256":"9859d16cebdee1659c725cd2d61d58d523fb26c4a7b22bc35da681ace300b394","excerpt":"we perform ten
