5-year Review: B. Haig: [TAS] 2019 update on P-values and significance (ASA II)(Guest Post)

This is the guest post by Bran Haig on July 12, 2019 in response to the “abandon statistical significance” editorial in The American Statistician (TAS) by Wasserstein, Schirm, and Lazar (WSL 2019). In the post it is referred to as ASAII with a note added once we learned that it is actually not a continuation of the 2016 ASA policy statement. (I decided to leave it that way, as otherwise the context seems lost. But in the title to this post, I refer to the journal TAS.) Brian lists some of the benefits that were to result from abandoning statistical significance. I welcome your constructive thoughts in the comments.

The American Statistical Association’s (ASA) recent effort to advise the statistical and scientific communities on how they should think about statistics in research is ambitious in scope. It is concerned with an initial attempt to depict what empirical research might look like in “a world beyond p<0.05” (The American Statistician, 2019, 73, S1,1-401). Quite surprisingly, the main recommendation of the lead editorial article in the Special Issue of The American Statistician devoted to this topic (Wasserstein, Schirm, & Lazar, 2019; hereafter, ASA II(note)) is that “it is time to stop using the term ‘statistically significant’ entirely”. (p.2) ASA II(note) acknowledges the controversial nature of this directive and anticipates that it will be subject to critical examination. Indeed, in a recent post, Deborah Mayo began her evaluation of ASA II(note) by making constructive amendments to three recommendations that appear early in the document (‘Error Statistics Philosophy’, June 17, 2019). These amendments have received numerous endorsements, and I record mine here. In this short commentary, I briefly state a number of general reservations that I have about ASA II(note).
