In Aug 1934 Harold Jeffreys first expresses the idea of Bayesian probability in his paper "Probability and Scientific Method". He argues that that it is not necessarily synonymous with frequency but based on a logical degree of prior belief given the data. Ronald Fisher of course rejected this idea

4/ Also most of you young'uns don't know about the Bad Old Days when we had to look up critical test statistics in printed tables. The tables were massive and for reasons of space were limited to 3 α levels: 0.05, 0.01, and 0.001 thresholds.

Few statisticians know that Frank Yates, pioneer of experimental design, is responsible for the annoying practice of indicating 3 tiers of statistical significance by stars (*p ≤ 0.05, **p ≤0.01, ***p ≤ 0.001). He soon regretted it and “vehemently opposed its unthinking use”. And here we are.

"a ‚significant' p-value between 0.01 and 0.05 should be interpreted with the expectation that the effect is exaggerated by more than 50% (median 1.56) and that an exact replication has about a one-in-three chance of also being significant." evidenceinthewild.com/p-value-look...
