Someone tells you one true thing about yourself - and suddenly you believe everything else they say.
You didn't decide to trust them. The trust simply arrived, riding on the one detail that happened to be correct. Psychics run on it. Frauds are built on it. Juries convict on it. And now machines run it at a scale no con artist ever dreamed of.
Look Again names the mechanism - the laundering signal: one verified detail certifying a stack of unverified ones - and follows it through true stories you won't be able to stop retelling:
The survivor who memorized her attacker's face to make him pay, identified the wrong man with eleven years of absolute certainty - and couldn't recognize the real one when he stood in front of her in court.
The con man who never forged a painting. He forged its history, planting fake records inside a real museum's archive - so that the more carefully buyers checked, the more completely they were deceived.
The cruise ship that ran aground seventeen miles from where its calm, experienced officers knew it to be - because a screen was more fluent than the sea.
Woven through them: the experiments that prove it's you too, and a clear-eyed account of what happens when AI starts arranging what you see before you see it.
The mechanisms are ancient. The machines are new. The defense is the same as it has always been - and it's in the title.
Read it in two sittings. See differently for years.
