About the Author

About the Author of Suspicious Minds

Rob Brotherton, author of Suspicious Minds: Why We Believe Conspiracy Theories, is a psychologist and leading expert on the cognitive origins of conspiracy theories. A former lecturer at Goldsmiths, University of London, and current Adjunct Assistant Professor at Barnard College, Columbia University, Brotherton combines academic rigor with accessible science communication to explore why people gravitate toward conspiratorial explanations.

His research, including a seminal study on the “intentionality bias” in conspiracy thinking published in PLOS ONE, underpins this examination of psychology’s role in shaping belief systems.

Brotherton’s work extends to his 2020 book Bad News: Why We Fall for Fake News, which analyzes the historical and psychological roots of misinformation. His insights have been featured in TIME, The Sunday Times, and New Scientist, and his research was spotlighted on Last Week Tonight with John Oliver.

He regularly contributes to his blog, ConspiracyPsychology.com, and engages with public audiences through media appearances and academic lectures. Suspicious Minds has been widely cited in psychology curricula and translated into multiple languages, cementing its status as a key text in understanding modern discourse.

FAQs About This Book

Suspicious Minds explores the psychology behind why people believe conspiracy theories, arguing they stem from innate cognitive biases rather than irrationality. Rob Brotherton examines historical examples and research to show how biases like pattern recognition and intentionality bias make conspiracies feel plausible, emphasizing these beliefs are a natural byproduct of human cognition.

This book is ideal for psychology enthusiasts, critical thinking advocates, and anyone curious about societal distrust. It offers value to academics studying cognitive biases, journalists analyzing misinformation trends, and general readers seeking science-based insights into conspiracy theories’ appeal.

Yes—critics praise its engaging blend of academic rigor and accessibility, with starred reviews from Library Journal and Publishers Weekly. The book balances historical context, experimental data, and witty prose to demystify conspiracy thinking without dismissing believers.

Brotherton highlights intentionality bias (attributing events to deliberate intent), pattern recognition (seeing connections in randomness), and proportionality bias (expecting large causes for major events). These mental shortcuts predispose humans to conspiracist explanations.

While discussing classics like the JFK assassination, Brotherton ties research to contemporary examples, showing how social media amplifies—but doesn’t create—conspiracism. He argues the internet merely accelerates sharing of theories rooted in timeless cognitive tendencies.

A key line states, “There are more conspiracy theorists out there than you might expect. Chances are you know some. Chances are you are one.” This underscores Brotherton’s thesis that conspiracism is a universal tendency, not a fringe aberration.

No—he avoids mockery, framing conspiracy theories as predictable cognitive responses. His research with Chris French shows even skeptical individuals exhibit intentionality bias, making conspiracy explanations feel intuitively compelling.

Suspicious Minds focuses on conspiracy theories’ cognitive roots, while Bad News addresses broader misinformation mechanisms like fake news. Both books analyze how biases shape beliefs, but the former delves deeper into intentionality and proportionality.

Some reviewers note Brotherton prioritizes psychological factors over sociological drivers (e.g., political alienation). However, his focus on universal cognitive traits helps explain conspiracism’s cross-cultural persistence.

The book provides tools to analyze events like COVID-19 misinformation or election fraud claims by highlighting how biases distort risk perception and evidence evaluation. It encourages questioning narratives without defaulting to cynicism.

Brotherton holds a PhD in psychology from Goldsmiths, University of London, and teaches at Barnard College, Columbia University. His research on conspiracist cognition has been featured in Scientific American and Last Week Tonight with John Oliver.

Despite AI-driven misinformation advances, Brotherton’s insights remain vital. The book explains why new technologies amplify—but don’t fundamentally alter—conspiracism’s cognitive underpinnings, offering a timeless framework for navigating modern information crises.
