Abandon Statistical Significance Blakeley B. McShane1, David Gal2, Andrew Gelman3,Christian Robert4, and Jennifer L. Tackett11 Northwestern University,2 University of Illinois at Chicago,3 Columbia University,4 Universit e Paris-Dauphine21 Sep 2017 AbstractIn science publishing and many areas of research, the status quo is a lexicographicdecision rule in which any result is first required to have ap-value that surpasses threshold and only then is consideration often scant given to such factors asprior and related evidence, plausibility of mechanism, study design and data quality,real world costs and benefits, novelty of finding, and other factors that vary by researchdomain. There have been recent proposals to change thep-value threshold, but insteadwe recommend abandoning the null hypothesis significance testing paradigm entirely,leavingp-values as just one of many pieces of information with no privileged role inscientific publication and decision making.
