Psychology’s ‘Reproducibility Project’ Efforts Reporting In


Nature News reports on the first wave of findings in the “crowd-sourced” effort to reproduce 100 of the most influential or important studies in psychology.

“An ambitious effort to replicate 100 research findings in psychology ended last week ‚ÄĒ and the data look worrying,” reports Nature News. “Results posted online on 24 April, which have not yet been peer-reviewed, suggest that key findings from only 39 of the published studies could be reproduced. But the situation is more nuanced than the top-line numbers suggest. Of the 61 non-replicated studies, scientists classed 24 as producing findings at least ‚Äúmoderately similar‚ÄĚ to those of the original experiments, even though they did not meet pre-established criteria, such as statistical significance, that would count as a successful replication.”
