Scientists Rise Up Against Statistical Significance

Amrhein, Greenland, McShane. 2019. (View Paper → )

Valentin Amrhein, Sander Greenland, Blake McShane and more than 800 signatories call for an end to hyped claims and the dismissal of possibly crucial effects…

In their article published in Nature, the authors and signatories argue against the reliance on statistical significance, specifically the use of a P-value threshold such as 0.05. They assert that this practice can lead to misleading claims and the dismissal of potentially important effects. The authors emphasize that it can result in the misinterpretation of non-significant results as evidence of no effect, as well as an overstatement of significant results.
