Diax chased the fortune-tellers out of the temple with a gardener's rake and left one rule behind: never believe a thing only because you wish it were true. The avout repeat it the way other people say grace. Erasmus admits the hard part out loud: he was still young enough to forget the Rake completely whenever he fell in love with some idea. That confession is the whole mechanism. Wanting-to-believe is the one bias nobody outgrows, so you build a habit that catches you in the act. Ripped from the novel: "one should never believe a thing only because one wishes that it were true." And: "you should not believe a thing only because you like to believe it." And Erasmus on himself: "I was still young enough that I could let myself forget about Diax's Rake when I was in love with some idea."

[Use when]

When you feel yourself getting excited about an idea. Ask what you would think of it if you disliked it.

[Why it matters]

The cheapest debiasing tool in the book. One sentence, works on anyone, and it targets the exact moment your judgment is weakest: when you're excited.
