Back in 2018 we wanted examine meta-analytic heterogeneity in research in social and cognitive psychology when there were only minor differences between primary studies, so we went looking for multi-lab replication projects. At the time, we found 10 multi-lab projects and during the years it took to publish the study (https://doi.org/10.1037/bul0000294) we added 3 more for a total of 13 projects with 68 primary effect sizes.
Recently I was looking for an updated list of multi-lab projects and couldn’t find one, so I collated my own. Below are all the published (human) multi-lab projects that I have been able to find at the time of writing (2023-02-23). There are now an impressive 32 human multi-lab projects published.
