The Ideological Brain with Dr Leor Zmigrod [Ep. 42]

In this episode of the Conflict Tipping podcast, Laura May speaks with political neuroscientist and psychologist Dr Leor Zmigrod, author of incredible new book The Ideological Brain. Leor’s groundbreaking research explores what makes our brains susceptible to rigid beliefs, ideological extremism, and group identity—drawing from cognitive science, psychology, and neuroscience.

Key Highlights:

• Why This Research? Leor shares what drew her to study ideological extremism, including her initial interest in understanding why some young people in Europe were drawn to join ISIS.

• What She Found From the Wisconsin Card Sorting Test to creative uses for a cup, Leor explains how unconscious cognitive patterns can predict a person’s openness—or vulnerability—to extreme ideologies.

• Intelligence vs. Rigidity Cognitive rigidity is distinct from intelligence. Flexible thinkers are more adaptable and less drawn to simplified worldviews.

• The Role of Culture and Stress Our brains react to environmental stress—and even mild discomfort—by narrowing perception and reducing openness. Scarcity and insecurity can make us more rigid, more tribal, and more susceptible to dehumanising others.

• Emotional Impulsivity and Extremism People drawn to ideological extremism tend to be more emotionally impulsive and reactive—highlighting the importance of emotion regulation and broader psychological support.

• So What? Practical Takeaways Why cognitive flexibility matters—for individuals and societies. How we can better design counter-extremism approaches, and what you can do to cultivate more flexible thinking.

Note from Laura May: due to circumstances beyond our control, a chunk of the recording where we talked about the brain on social media, and about even more findings from Leor's fantastic book, was lost—so I insist you buy a copy of her book!

About the Book

Leor’s new book, The Ideological Brain, takes readers on a journey through the psychology and neuroscience of belief, showing how dogmatic ideologies can shape not just our thinking, but our biology—and why this matters now more than ever.
