Dozens of Labs Respond to Call to Bolster Reliability of Psychology Research
A large international group set up to test the reliability of psychology experiments has successfully reproduced the results of 10 out of 13 past experiments. The consortium also found that two effects could not be reproduced.
Psychology has been buffeted in recent years by mounting concern over the reliability of its results, after repeated failures to replicate classic studies. A failure to replicate could mean that the original study was flawed, the new experiment was poorly done or the effect under scrutiny varies between settings or groups of people.
To tackle this ‘replicability crisis’, 36 research groups formed the Many Labs Replication Project to repeat 13 psychological studies. The consortium combined tests from earlier experiments into a single questionnaire — meant to take 15 minutes to complete — and delivered it to 6,344 volunteers from 12 countries.
