And that's what this book is about. Robert Levine is a social psychologist who studied how we are persuaded, how salespeople sell, how people are brought into cults, how children resist—or don't resist—peer pressure, and some of the cultural differences in learning to resist invisible forces of persuasion. To that end, Levine learned how to sell cars himself, attended Tupperware parties, and met with former cult members, in each instance laying out clearly how our sense of ourselves as independent thinkers is an illusion, that we can be subtly and gradually manipulated, leaving us prey to the blandishments of people who, purporting to care for us, truly care only for themselves. But by creating the lethal combination of (apparent) expertise, honesty, and likeability, these individuals draw us into their nets.
