Grit narratives create a systematic bias against quitting even when quitting is correct

Duke argues that cultural storytelling — inspirational speeches, biographies of famous persisters, workplace mottoes — almost exclusively celebrates people who refused to give up, creating a skewed sample where we only hear about persistence that eventually paid off. The much larger, less visible group of people who persisted in a losing effort and simply failed rarely gets a public narrative, because failure stories aren't told the same way success stories are.

This survivorship bias, she argues, quietly teaches people that persistence is nearly always the right answer, when in reality persistence and quitting are both sometimes right, depending entirely on the actual expected value of continuing versus stopping. The stories we're told say nothing reliable about which choice is statistically wiser in a given situation.

Her point isn't that persistence is bad, but that our information diet about it is badly distorted, making quitting seem shameful by comparison, when it's often just the correct call. We only hear the persistence stories that worked, which skews how we judge whether persisting is usually wise.
