What was done
Researchers conducted an exact multilab replication of Gürerk, Irlenbusch, and Rockenbach (Science, 2006) to test whether groups with peer-sanctioning institutions (rewarding cooperators and punishing defectors) outperform groups without sanctioning. The study enrolled 1,008 participants across 7 European labs, structured as 12 groups of 12 participants per lab, compared to the original study's sample of 84 participants across 7 groups in 1 lab.
What was found
The replication met all preregistered success criteria in 5 of the 7 participating labs. In those 5 labs, the majority of participants chose to join groups with a sanctioning institution, achieving higher average cooperation and profits compared to groups without sanctioning. In the remaining 2 labs, results were weaker but still directionally favored sanctioning institutions. Exact numerical effect sizes, participation rates, and profit figures were not reported in the abstract.
Why it matters
This large-scale replication establishes that the competitive advantage of peer sanctioning and institutional self-selection in promoting human cooperation is robust across multiple laboratory settings.
Limits
The study tested human behavior in artificial laboratory environments, which may not capture complex real-world institutional dynamics. The abstract notes that findings are established specifically within a European context, leaving cross-cultural generalizability unverified. Two of the seven labs showed weaker results, and specific quantitative estimates and variance parameters were not provided in the abstract.
