WebAuthors such as Gigerenzer have argued that today’s use of hypothesis-testing procedures constitutes an inappropriate hybrid of Fisherian, Neyman-Pearson, and Bayesian ideas and that historic rituals such as the routine setting up of null hypotheses and the use of 0.05 significance levels constitutes an epidemic of the “mindless” use of statistics across the … In the development of classical statistics in the second quarter of the 20th century two competing models of inductive statistical testing were developed. Their relative merits were hotly debated (for over 25 years) until Fisher's death. While a hybrid of the two methods is widely taught and used, the philosophical questions raised in the debate have not been resolved.

WebFisher (1955, p. 74) complained, justifiably, that his significance test had become “assimilated” into the N–P hypothesis testing framework. This assimilation has occurred, despite the fact, shown by Hubbard and Bayarri (2003, p. 174), that α plays no role in Fisherian significance tests. Moreover, the p value plays no role in N–P ...
