What's a Replication of a Set of Studies?

Earlier this year, the last of five "Many Labs" projects was accepted for publication at Collabra: Psychology, representating the culmination of a nearly-decade long series of multi-lab replication efforts. In this episode, Alexa and Yoel consider what they've learned from Many Labs 1 through 5, including insights about replication, expertise, and the impact (or lack thereof) of small effects. They also discuss their own connections to the project - Yoel as an original author, and Alexa as a researcher examing psychologists' reactions to the findings. Although the co-hosts deny they have any existential fear of death (see Many Labs 4) they do share their most recent life-threatening experiences.
