from Web Literacy for Student Fact-Checkers by Michael A. Caulfield
"The habit is simple. When you feel strong emotion–happiness, anger, pride, vindication–and that emotion pushes you to share a “fact” with others, STOP. Above all, these are the claims that you must fact-check.
Why? Because you’re already likely to check things you know are important to get right, and you’re predisposed to analyze things that put you an intellectual frame of mind. But things that make you angry or overjoyed, well… our record as humans are not good with these things".
