Governments, mass media, and other mechanized forces use fear, loneliness, and isolation to demoralize populations and exert control, persuading large groups of people to act against their own interests, always with destructive results. In , world-renowned Professor of Clinical Psychology Mattias Desmet deconstructs the societal conditions that allow this collective psychosis to take hold. By looking at our current situation and identifying the phenomenon of “mass formation”—a type of collective hypnosis—he clearly illustrates how close we are to surrendering to totalitarian regimes. With detailed analyses, examples, and results from years of research, Desmet lays out the steps that lead toward mass formation, including: In addition to clear psychological analysis—and building on Hannah Arendt’s essential work on totalitarianism, —Desmet offers a sharp critique of the cultural groupthink that exists throughout society. He cautions against the dangers of our current cultural landscape, media consumption, and reliance on manipulative technologies and then offers simple solutions—both individual and collective—to prevent the willing sacrifice of our freedoms. “We can honor the right to freedom of expression and the right to self-determination without feeling threatened by each other,” Desmet writes. “But there is a point where .
