You think about something you don't say it out loud, you don't search for it, and there it is in your feed.
How does it know?
Almost everyone has had the moment. The ad for the exact thing you'd been considering. The song that lands the day you needed it. The quiet sense that something out there is paying attention, and knows you a little too well.
Most people assume their phone is listening. The real answer is stranger, and far more interesting: it doesn't need to.
How Does It Know? takes you behind the screen, into the algorithms, the data, the psychology, and the business of attention, to show how the feed predicts what you'll want, how you feel, and what you'll do next, often before you know it yourself. No jargon. No fearmongering. Just a plain-spoken look at what's actually happening every time it feels like your phone read your mind.
This isn't a book that tells you to throw your phone in a drawer. It's one that hands you something quieter and more useful: a clearer picture. Because once you can see how it works, you start to see your own patterns too, and that's where paying attention stops feeling like being watched, and starts feeling like waking up.
