It means if you don’t know if someone did something because they had evil plans or were fking stulud, its safe to assume they were fking stupid at the point of the incident.
Especially if the evil plan would have been convoluted and required things to align just perfect for the plan to be successful.
But it is not safe to make that assumption. It’s wildly dangerous to label evil as stupid. Giving evil people an in is how we get to where we are.
It’s called Hanlon’s razor, a take on Occam’s razor, the unstated part is “all else being equal”.
I was just explaining to the commenter above what was meant by the saying. I never said it was correct in all situations.
If you have an issue with the saying, you’re free to give Robert j. Halon your feedback.
