『Invisible City』の著者について

Shankar Vedantam, bestselling author and host of NPR’s Hidden Brain podcast, teams with science writer Bill Mesler in Useful Delusions: The Power and Paradox of the Self-Deceiving Brain, exploring psychology’s intersection with societal behavior.

Vedantam, a Stanford-trained journalist and social science correspondent, built his career dissecting unconscious biases through his Hidden Brain platform—a top-ranked podcast with over three million weekly downloads—and his acclaimed book The Hidden Brain, which won the Edward R. Murrow Award. Mesler, a historian and coauthor of A Brief History of Creation, contributes expertise in science communication. Together, they examine how self-deception shapes human resilience and collective action, drawing on Vedantam’s NPR reporting and Mesler’s focus on scientific narratives.

Useful Delusions was named a 2021 Behavioral Scientist Notable Book and a Next Big Idea Club selection, solidifying its status in popular psychology. Vedantam’s work is frequently cited in academic circles and media outlets like The Washington Post, where he authored the “Department of Human Behavior” column. The book reflects his two-decade career bridging journalism and cognitive science, offering fresh perspectives on truth’s role in human progress.

『Invisible City』に関するよくある質問

What is Useful Delusions by Shankar Vedantam about?

Useful Delusions explores how self-deception shapes human behavior, arguing that certain illusions—like beliefs in love or national identity—serve emotional and social benefits. Through case studies like Donald Lowry’s “Church of Love” scam and the placebo effect, Vedantam reveals how delusions help individuals and societies cope with reality. The book blends psychology, history, and storytelling to examine why our brains cling to falsehoods.

Who should read Useful Delusions?

This book suits readers interested in psychology, behavioral science, or the paradoxes of human behavior. It’s ideal for those curious about how myths and lies influence personal relationships, politics, and culture. Fans of Vedantam’s Hidden Brain podcast or works by Daniel Kahneman will appreciate its accessible blend of research and narrative.

Is Useful Delusions worth reading?

Yes, particularly for its thought-provoking analysis of self-deception’s societal role. Reviewers praise its engaging storytelling and real-world examples, though some note a desire for deeper theoretical exploration. The book offers fresh perspectives on topics like religion and propaganda, making it valuable for rethinking assumptions about truth and fiction.

What are the main ideas in Useful Delusions?

• Self-deception as survival tool: Delusions help individuals manage stress and build social bonds.
• Collective myths: Shared falsehoods (e.g., national pride) foster community cohesion.
• The cost-benefit paradox: While some delusions are adaptive, others enable exploitation, as seen in cons and scams.

How does Useful Delusions explain the placebo effect?

Vedantam frames the placebo effect as a form of beneficial self-deception, where belief in treatment efficacy triggers real physiological improvements. This example underscores how the brain’s capacity for illusion can enhance health outcomes, even without active medication.

What is the “Church of Love” case study in Useful Delusions?

The book analyzes Donald Lowry’s 1970s “Church of Love” scam, where thousands paid for fake ordinations. Vedantam uses this to illustrate how people embrace lies that offer purpose or identity, highlighting self-deception’s power to fulfill emotional needs despite logical contradictions.

How does Useful Delusions compare to Thinking, Fast and Slow?

While both explore cognitive biases, Useful Delusions focuses specifically on the utility of self-deception, whereas Kahneman’s work examines broader decision-making systems. Vedantam prioritizes narrative-driven examples, while Kahneman emphasizes experimental psychology.

What criticisms exist about Useful Delusions?

Some reviewers argue the book oversimplifies complex psychological concepts or neglects deeper philosophical questions about truth. Others note that its optimistic view of self-deception risks downplaying dangers like misinformation.

How does Shankar Vedantam’s background influence Useful Delusions?

Drawing on his tenure as NPR’s social science correspondent and Hidden Brain host, Vedantam combines journalistic storytelling with interdisciplinary research. His focus on human behavior’s paradoxes informs the book’s accessible yet rigorous approach.

Can Useful Delusions help with personal growth?

Yes. By understanding how self-deception shapes habits and relationships, readers can better identify which illusions serve them and which hinder growth. The book encourages critical reflection on beliefs about success, love, and identity.

Why is Useful Delusions relevant in 2025?

In an era of AI-driven misinformation and polarized narratives, the book’s insights into collective delusions offer tools to navigate propaganda, conspiracy theories, and societal myths. It underscores the urgency of discerning harmful falsehoods from unifying stories.

What quotes highlight key themes in Useful Delusions?

• On delusions: “Our brains craft lies not to obscure truth, but to make life survivable.”
• On community: “Shared myths are the glue that binds strangers into tribes.”

These lines encapsulate the book’s central thesis about self-deception’s dual-edged power.
