Despite its best efforts, the project, called Many Labs 2, has only succeeded in 14 out of 28 cases. Six years ago, that might have been shocking. Now it comes as expected (if still somewhat disturbing) news.

In recent years, it has become painfully clear that psychology is facing a “reproducibility crisis,” in which even famous, long-established phenomena—the stuff of textbooks and ted Talks—might not be real.
