My friend @Ctzn5, who goes by JJ, came up with a useful corollary to Hanlon’s razor. I’m posting it here so that I can easily link to it whenever, instead of needing to dig through Twitter search every time.
To refresh your memory, Hanlon’s razor goes like this: “Never attribute to malice that which is adequately explained by stupidity.”
JJ’s addition (which dates to 2016, as far as I know) points out the futility of Hanlon’s: “The intentionality of an agent with behavior sufficiently indistinguishable from malice is irrelevant.”
I think JJ’s razor could use rephrasing for pithiness, but I’m not sure what would be ideal. Perhaps: “Malicious or stupid, it doesn’t matter, because your options are the same.”
