The Ego has landed! The .05 level of statistical significance is soft (Fisher) rather than hard (Neyman/Pearson)

Journal/Book: Behav Brain Sci. 1998; 21: 40 West 20TH Street, New York, NY 10011-4211. Cambridge Univ Press. 207.

Abstract: Chow pays lip service (but not much more!) to Type I errors and thus opts for a hard (all-or-none) .05 level of significance (Superego of Newman/Pearson theory; Gigerenzer 1993). Most working scientists disregard Type I errors and thus utilize a soft .05 level (Ego of Fisher; Gigerenzer 1993), which lets them report gradations of significance (e.g., p < .001).
