Fact-check the thing you agree with hardest. That’s where you’re easiest to fool.

Scepticism switches on automatically for claims that bother you and switches off for claims that please you. Anything confirming what you already believe gets waved through without the questions you would have put to an opponent, which is why the stories that fool careful people are the ones they wanted to hear. Your blind spot sits exactly where your agreement is strongest.

Take the claim you have shared most confidently this month and look for its source. Try to find the best argument against it, written by someone reasonable. If it survives that, you now hold it for better reasons than before.
