These concise guides are an antidote to confusion, tracing major political ideas from their origins to today''s headlines.The world has always had conspiracy theories. From the Illuminati to the deep state, the JFK assassination to the death of Princess Diana - there have always been those who believe that events are manipulated by shadowy forces with sinister intent. But in recent years, conspiracism has colonised the mainstream. These days, it is a booming industry, a political strategy and a pseudo-religion - and it''s threatening the foundations of liberal democracy.Where once political battles were fought over ideas and values, it now feels as though we''re arguing over the nature of reality itself. The problem is bigger than lizard people or UFOs: left unchecked, conspiracy theories have the power to warp the fabric of society and justify unspeakable crimes.In Conspiracy Theory: The Story of an Idea, Ian Dunt and Dorian Lynskey pull back the curtain on conspiracy theories: where they come from, who promotes them, how they work, and what they''re doing to us. From biblical myth to online hysteria, this book explains what happens when the human gift for storytelling goes wrong - and how we might restore our common reality.
