Sometimes it just works to insist you did the work… I say I looked into <> extensively and that’s what I found. Feel free to come back later and present me with evidence to the contrary. And (this is the crucial part) I just don’t accept any further argument in that moment. Honestly this worked so many times. Like barely anybody ever came back to me another day but at the very least I got them to shut up in the moment.
