How Reproducible Are Results from Empirical Psychology?

Susann Fiedler

To maintain confidence in scientific findings, the project presented in this video by SUSANN FIEDLER examines the reproducibility rate of empirical results in psychology: Studies published in three major psychological journals in 2008 are replicated by other researchers in collaboration with the original authors. The results of original and replicated studies are compared to determine the general reproducibility rate in psychological science as well as the factors that predict it.

Researcher

Susann Fiedler is the Head of the Gielen-Leyendecker Research Group at the Max Planck Institute for Research on Collective Goods in Bonn, Germany. In 2013, she received her PhD in Psychology for her thesis with the topic “Information Search in Multi-attribute Decision Making”. Apart from behavioral economics and decision making, her current research also investigates methodological challenges present in psychological research. In 2015, Fiedler has received the Otto Hahn Medal for outstanding scientific achievements from the Max Planck Society.

Max Planck Institute for Research on Collective Goods

Initially founded as a Max Planck institute that investigates the provision of collective goods, the institute has developed into an international hub that focuses in its research mainly on applied economics and on behavioral law. Moreover, the institute hosts three independent research groups on “moral courage”, “economic cognition”, and “mechanisms of normative change”. The set of researchers from various disciplines, such as economics, law, psychology, and sociology, constitutes a truly interdisciplinary environment that facilitates a cross-fertilization of ideas.
