Yesterday brought the issuance of dozens of papers about the importance – or not – of p-values. That’s important news for trial lawyers, corporate officers, corporate directors, and risk managers. Persons in those roles (and others) are in for surprises if not aware of and ready for debates about and likely reduction in the litigation-related power of p values. Indeed, the many papers issued yesterday on use of statistics deserve attention when thinking about opportunities and risks in litigation.

For yesterday’s editorial from the American Statistical Association, and more, go to “Moving to a World Beyond “p < 0.05.”

For the paper shown in the cartoon, go here to Nature.

For cogent history regarding use of p values in court, see my post back in 2012, as some of the debates were simmering.

For very learned discussion of the topic, see my prior post pointing out Nathan Schachtman’s pointed 2018 analysis of the use of of p values, and his critique of arguments to reduce reliance on the .05 standard.
