In the last few decades, psychology has experienced a replication crisis: Many apparently well-established textbook findings have been impossible to replicate. Reasons for this include a likely abundance of false-positive results in the psychology literature (via questionable research practices), and the fact that many studies do not contain sufficient information to know what was done.

For example, if it is unclear how the original data were processed and analyzed, reanalyses of these data may provide results that differ from the original results. So, not knowing all the steps that researchers took to obtain their results makes it impossible to gauge the robustness of any effect in psychology. Because reproducible results are critical for scientific progress, researchers need to do their utmost to ensure reproducibility. Two practices are particularly promising: Preregistration and data sharing.

The goal of this course is to understand how to conduct reproducible science. This course will allow students to explore key concepts in reproducibility and to help them conduct reproducible research. As part of the course, students will write a preregistration (actual or hypothetical) and learn how to share data (actual or hypothetical) via the Stockholm University depository.

This course is offered as part of the research education for doctoral students at the Department of Psychology, Stockholm University.

To facilitate understanding, students will have the opportunity to participate in discussion seminars on selected papers through ReproducibiliTea journal club headed by Stephen Pierzchajlo and Rasmus Eklund.
