On Being Certain: Believing You Are Right Even When You're Not by Robert A. Burton

Summary

In 'On Being Certain,' neurologist Robert A. Burton explores the compelling feeling of certainty that often accompanies our beliefs and how it can be misleading. He argues that the sensation of knowing is a neurological phenomenon, distinct from logic or evidence, and highlights how this can lead us astray in our thinking. Drawing on neuroscience, psychology, and real-world examples, Burton reveals the limitations of self-awareness and rationality, urging readers to embrace uncertainty and question their convictions. The book not only examines the roots of belief but also provides insight into how we can be more open-minded and flexible in our thinking.

Life-Changing Lessons

1. Certainty is a feeling, not proof: Our sense of being right is a subjective neurological state and not a guarantee of factual correctness.

2. Embracing doubt leads to better decisions: Acknowledging the limits of our knowledge helps us make more informed and less biased choices.

3. Introspection has limits: We cannot always trust our own minds to accurately report how or why we believe something, which means humility is essential in debates and self-understanding.

Practical Examples

1. Medical Misdiagnosis

   Burton describes how even the most experienced physicians can be utterly certain about a diagnosis, only to be proven wrong by later evidence. This example highlights how neurologically-based conviction can persist even when it contradicts reality, emphasizing the dangers of overconfidence in high-stakes environments.

2. Political Beliefs

   The book illustrates how political ideology often feels self-evidently correct to individuals, regardless of contradictory information. Burton explains that this certainty emerges from neurological processes, not simply conscious analysis, helping explain the persistence of polarization.

3. Memory Fallibility

   Burton discusses experiments where people recall seeing words on a list that were never actually presented, yet they remain confident about their memory. This shows how certainty about memories is not a reliable indicator of their truthfulness, cautioning against trusting our recollections too implicitly.

4. Coin Flipping Experiment

   He recounts studies in which participants become convinced they can predict the outcome of random coin tosses, demonstrating how the brain's search for patterns can give rise to rationalizations and certainty even in the face of statistical randomness.

5. Mathematical Reasoning

   Burton explores cases where people are sure they've solved a math problem correctly, only to realize later they made logical errors. This underscores how feelings of confidence can arise from intuitive, automatic mental processes rather than actual accuracy.

6. Scientific Paradigm Shifts

   He details how established scientific communities have resisted new theories, such as plate tectonics or relativity, because of a profound shared certainty in prevailing ideas. This shows that even science, which prizes open-mindedness, is not immune to neurobiological certainty.

7. Gut Feelings in Investing

   The author analyzes how investors trust their gut instincts when making financial decisions, often sticking with losing stocks due to an unshakable sense of being right, revealing the personal and economic costs of misplaced certainty.

8. Religious Conviction

   Burton discusses how the neurological origins of belief make religious experiences feel absolutely, unarguably true to those who have them. This is used to explain why rational argument alone rarely shifts deeply held spiritual convictions.

9. Jury Deliberation

   He points to court cases where jurors feel totally certain about a defendant’s guilt or innocence, sometimes despite ambiguous evidence. This example calls attention to the potential for justice to be undermined by misplaced confidence.
