Conspiracy theories have always existed in our world. They have been used in their most extreme form to justify tyranny and genocide.

From the Illuminati to the deep state, from the assassination of Kennedy to the death of Princess Diana, there have always been those who believed that events were guided by some invisible, devious hand.

In recent years, conspiracy theories have become mainstream: a booming industry, a strategy that undermines democratic processes.

In this book, Ian Dunt and Dorian Lynskey analyze conspiracy theories in depth: what their origins are, who promotes them, how they affect us, and most importantly, how we can act and react to prevent the spread of suspicion and misinformation.
