An eye-opening look at the small communities of propagandists revolutionizing politics, culture, and society "Essential and riveting reading." --Jonathan Haidt, author of The Anxious Generation Invisible Rulers is about a profound transformation in power and influence that is altering our politics, our government, and even our relationships with friends and neighbors. Today, online propagandists increasingly shape public opinion and even control our relationship to the truth. Our shared reality has splintered into discrete bespoke realities driven by algorithms, influencers, and curated content. Very little can bridge the divide, making democratic consensus nearly impossible to achieve. Renée DiResta exposes how these propagandists and their followers undermine the institutions that make society work, from anti-vaccine zealots who flood social media with fringe viewpoints to political influencers who use AI-generated images to manipulate our perception of reality. She also provides readers with a new conception of civics that helps us understand and fight back against these new invisible rulers.
