LESSON 7 · The Mental Models Playbook
Assume Ignorance Before Malice
Hanlon's Razor states: "Never attribute to malice that which is adequately explained by stupidity" — or more charitably, by ignorance, oversight, or error.

This principle is powerful because humans have a strong tendency toward hostile attribution bias — interpreting ambiguous actions as intentionally harmful. This bias served our ancestors well, but in modern life it generates unnecessary conflict, paranoia, and damaged relationships.
