I want you to think about the last time you encountered an achievement that seemed too large for the person who produced it. Something that made you pause, narrow your eyes, and reach for the comfortable explanation. Maybe it was a historical figure whose story sounded exaggerated. Maybe it was a living person whose accomplishment struck you as implausible given what you thought you knew about their background, their body, their circumstances. You felt a flicker. A small, quiet impulse that said: that cannot be right.
