People demand nuance for themselves and simplicity for those they condemn.

You know your own context completely, so your failures come with reasons attached. Other people arrive as actions with no interior, so their failures look like character. That asymmetry is not hypocrisy exactly; it is a difference in available information that produces hypocrisy reliably if unexamined.

When you are certain about someone’s motives, remember that you are working from the outside of them. Ask what context would make their behaviour understandable, and grant them at least the possibility of having one.
