This week, we revisit one of our favorite episodes from last year (with improved audio quality!).  In this episode, Anjie chats with Edouard Machery, a Distinguished Professor in the Department of History and Philosophy of Science at the University of Pittsburgh. He is also the Director of the Center for Philosophy of Science. Edouard's main research focuses on the intersection between cognitive science and philosophy. In this episode, Edouard shares his recent work on a topic that is extremely important for psychology today: replication. In an era of the replication crisis, it is more important than ever to understand the concept of replication. What are we really talking about when we are talking about replication? Is preregistration the cure-all magic for the crisis? Why is scientific reform so difficult? These are the questions Edouard ponders. You can learn more about his research on his personal website. Paper: Machery, E. (2020). What is a replication?. Philosophy of Science, 87(4), 545-567.
