Susann Fiedler How Reproducible Are Results from Empirical Psychology?

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 Society

"The Max Planck Society is Germany's most successful research organization. Since its establishment in 1948, no fewer than 18 Nobel laureates have emerged from the ranks of its scientists, putting it on a par with the best and most prestigious research institutions worldwide. The more than 15,000 publications each year in internationally renowned scientific journals are proof of the outstanding research work conducted at Max Planck Institutes – and many of those articles are among the most-cited publications in the relevant field."

Max Planck Institute for Research on Collective Goods

"Many goods are not obviously best provided by unregulated markets. This does not necessarily imply that government does a better job. But research can do society a service in defining why markets have a hard time with some goods, and in comparing institutional arrangements aiming at their provision. In a precise way, the problem is defined by the concept of public goods. Capitalising on the theory of mechanism design, it can be further improved. Using experimental methods, it can be put into perspective. Yet some social dilemmas are better analysed in alternative categories. It may even be preferable to start analytically from the political decision to intervene into markets. The institute tackles these questions from the combined perspectives of economics, law and psychology. While the institute started with applications from environmental problems, current work focuses on antitrust, regulation and financial stability." (Source)


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.
