Distributions of

pwere found to be similar across the different journals. Moreover,pvalues were much more common immediately below .05 than would be expected based on the number ofpvalues occurring in other ranges…

The present study observed evidence of an overreliance on null-hypothesis signiﬁcance testing (NHST) in psychological research. NHST may encourage researchers to focus chieﬂy on achieving a sufﬁciently low value of p. Consistent with that view, the p value distribution from three well-respected psychology journals was disturbed such that an unusually high number of p values occurred immediately below the threshold for statistical signiﬁcance.
