maybe WE SHOULD STOP USING FUCKING P-VALUES FOR HYPOTHESIS TESTING.

There's some... tension between this correct statement and the rest of your blog post :-/

You're right, I added a paragraph explaining why I do this:

P-values aren’t very useful in

getting close to the truth, but they’re everywhere, they’re easy to work with and they’re moderately useful forgetting away from bullshit. Since the latter is our goal in this essay we’ll stick with looking at p-values for now.

Since you see p-values reported all the time and they're easy to calculate (because they're uniformly distributed), there's value in extracting whatever useful evidence there is in p-values.

Unfortunately for the author's "Rule of two Ns", "Bonferonni" is actually spelt "Bonferroni".

I feel like such a dumbass.

You could correct the post as "Both 'Dunn' and 'Bonferroni' have exactly two 'n' in them. Thus we have etc."

That's a good suggestion, but I actually had to update that entire section because the math had an embarrassing mistake and I renamed the rule.

By the way, I have a policy on my blog of paying bounties to commenters who catch major errors. I sent $5 to the commenter who pointed out where I messed up the math. If you see a really stupid mistake on Putanumonit, leave a comment there and make a buck.
