Abstract

What share of results replicate in different literatures in some of the experimental social sciences? I will discuss several large replication projects in mainly psychology and economics, where my coauthors and I have redone experiments published in high impact journals with new and larger samples to see whether the main result replicates.

The seminar will also cover our studies on “wisdom of crowds” mechanisms like prediction markets and forecasting surveys where researchers attempt to predict these replication outcomes as well as outcomes of new hypothesis tests, as well as recent work on multi-analyst projects and conceptual replications where we either ask researchers to test the same hypotheses on the same data or to design experiments testing the same hypothesis
