It also seems unprofessional to call Sir Fisher an "ass", which is called an ad-hominem attack (attack on the person is obviously not a valid logical argument), and one of a dead person at that. Fact is: Fisher made fundamental contributions and the poster himself uses these on a daily basis: "Student" [Gossett]'s t-distribution, Fisher's linear discriminant, a precursor of linear discriminant analysis, ANOVA, Fisher information, Fisher's scoring, Minimum Fisher information, the F-distribution, Fisher–Tippett–Gnedenko theorem, the Fisher-Yates shuffle algorithm, the von Mises–Fisher distribution, inverse probability, Fisher's permutation test Fisher's inequality, sufficiency of a statistic, and more. His contribution to biology are even more impactful. It also happens that Fisher was a proponent of the "Frequentist" interpretation of probabilities, whereas the poster belongs to the recently more popular "Bayesian" camp of ideology (yes, ideology, if you think statistics as a part of mathematics is free from that, welcome to real life!). He further held strong views about races, perhaps because he was a professor of eugenics (which we today know as incorrect unscientific nonsense, but obviously that was not the state at the time), and there is am ongoing controversy regarding whether he was a racist or not. What I read about him suggests to me I may not have liked him, but to just stamp him as "ass" wihtout elaborating is too cheap for a statistcs professional in my view. But then this is a personal blog, where the poster can write whatever he wants under US law.
