Those who’ve been following the most recent controversy over the replicability of psychological findings (see here, here, here, here, and here for a primer), may be interested in the latest output from the PsyBorgs Digital History of Psychology Laboratory. Michael Pettit (left) has created an interactive timeline of replication controversies over psychology’s history:

This interactive timeline offers the reader a brief guide to this longer history. I define replication fairly broadly, but attempt to not simply offer a history of psychology in its entirety. Instead, I have focused on famous replication controversies from the past alongside the development of psychology’s favored research methods.

I am personally quite agnostic as to the value of the current interest in direct replication. My worry is that it distracts (as is often the case in psychology) from questions of external validity. My goal is to provide a richer context for contemporary controversies animating psychology.

I welcome corrections, updates, and suggestions of relevant topics. Please contact me at mpettit at yorku.ca

The timeline can be explored in full here.
