Because brainwashing affects both the world and our observation of the world, we often don't recognize it while it's happening―unless we know where to look. As Rebecca Lemov writes in her new book The Instability of Truth, "Brainwashing erases itself." What we call brainwashing is more common than we think; it is not so much what happens to other people as what can happen to anyone.

In her work, Lemov exposes the myriad ways our minds can be controlled against our will, from the brainwashing techniques used against American POWs in North Korea to the "soft" brainwashing of social media doomscrolling and behavior-shaping.

Rebecca Lemov is a historian of science at Harvard University and has been a visiting scholar at the Max Planck Institute. Her research explores data, technology, and the history of human and behavioral sciences. Her new book is The Instability of Truth: Brainwashing, Mind Control, and Hyper-Persuasion.
