The Hidden Power of Doubt and Uncertainty
Shankar Vedantam explores how doubt, often viewed negatively, can be a powerful tool for growth and better decision-making. Bobby Parmar, author of "Radical Doubt," illustrates this through General Eisenhower's D-Day example, where public confidence was balanced with private doubt and preparation for potential failure.
Leveraging Doubt for Better Decisions
Parmar argues that doubt is particularly valuable in complex situations. He introduces "Anomalizing," a strategy of noticing early warning signs, and advocates for using doubt to examine various solutions rather than rushing to certainty. Through his own experience leading a challenging expedition, Parmar demonstrates how stepping back to reassess situations can lead to better outcomes. He notes that while novices often treat intuition as definitive, experts use it as a starting point for questioning and strategy development.
The Neuroscience of Decision-Making Under Uncertainty
The brain employs a "pause and piece together" system when experiencing doubt, but this can be overwhelmed during periods of acute stress. Parmar cautions that overconfidence and the need for certainty can blind individuals to potential risks, while confirmation bias often prevents people from seeking contradictory information after making decisions.
Strategies For Reducing Defensiveness When Receiving Feedback
Emily Falk explains that feedback often feels like an attack on our identity because our brain conflates identity with values. This reaction is compounded by the fact that we judge ourselves by intentions while others see only our actions.
Managing Feedback Effectively
Falk suggests several strategies for handling feedback constructively, including values affirmation exercises for psychological distance and framing feedback as collaborative problem-solving. She emphasizes the importance of maintaining a balance between openness to feedback and discernment, recommending a "hopeful skeptic" approach that allows for growth while protecting self-worth.

Clarifications
- "Anomalizing" is the practice of actively identifying and focusing on anomalies—unexpected or unusual signs that deviate from normal patterns. It helps in early detection of potential problems or risks by questioning assumptions. This approach encourages critical thinking and prevents premature conclusions. It is used to improve decision-making by highlighting what might otherwise be overlooked.
- General Eisenhower publicly expressed confidence about the success of the D-Day invasion to maintain morale among troops and the public. Privately, he prepared a contingency plan, including a draft of a letter taking responsibility if the invasion failed. This demonstrated his use of doubt to anticipate possible failure and plan accordingly. His approach balanced optimism with realistic caution, enhancing decision-making under uncertainty.
- The brain's "pause and piece together" system involves the prefrontal cortex, which slows down decision-making to analyze information carefully. This process helps integrate new evidence and reassess assumptions before acting. Under stress, the amygdala can override this system, triggering quick, instinctive responses instead. Effective doubt relies on balancing this reflective pause with emotional regulation.
- Feedback feels like an attack on identity because the brain links self-worth to core values and beliefs. When feedback challenges actions, it is perceived as threatening these deeply held values. This triggers a defensive response to protect one's sense of self. Additionally, people interpret feedback through their own intentions, while others judge only observable behavior, creating a disconnect that feels personal.
- When judging ourselves, we focus on our intentions—what we meant to do—because we have access to our internal thoughts and motivations. Others only see our external actions and outcomes, lacking insight into our intentions. This difference can cause misunderstandings, as people may judge us harshly based on results without knowing our reasons. Recognizing this gap helps reduce defensiveness when receiving feedback.
- Values affirmation exercises involve reflecting on and writing about core personal values to reinforce self-identity. This process helps reduce defensiveness by reminding individuals of their broader sense of self beyond the immediate feedback. It creates psychological distance, making criticism feel less like a personal attack. As a result, people become more open to constructive feedback and less reactive.
- A "hopeful skeptic" mindset means being open to new ideas while maintaining a critical perspective. It involves balancing optimism about potential benefits with careful evaluation of evidence. This approach helps protect against being misled or overly defensive. It encourages growth by allowing constructive feedback without compromising self-worth.
Counterarguments
- While doubt can be beneficial, excessive doubt can lead to decision paralysis, where an individual or organization is unable to make any decision due to fear of making the wrong one.
- Eisenhower's balance of confidence and doubt may not be applicable in all leadership scenarios; different situations may call for different approaches.
- The concept of "Anomalizing" might not always be practical, as not all early warning signs are easily identifiable or may be misinterpreted, leading to incorrect conclusions.
- Relying on doubt to examine multiple solutions could sometimes result in missed opportunities if decisions need to be made swiftly to capitalize on time-sensitive situations.
- While experts may use intuition as a starting point for further inquiry, there are instances where expert intuition is highly accurate and can be trusted without extensive questioning.
- The "pause and piece together" mechanism might not be the only or the most effective way the brain deals with uncertainty; other cognitive processes could also play significant roles.
- Overconfidence and desire for certainty are not universally detrimental; in some cases, they can lead to decisive action and clear direction, which can be beneficial.
- Confirmation bias is a natural cognitive tendency that can sometimes help in efficiently processing information and making quick decisions based on past experiences.
- Feedback can be perceived as constructive without necessarily feeling like an attack on identity; this perception can vary widely among individuals.
- The strategies for managing feedback, such as values affirmation exercises, may not be effective for everyone and could be seen as overly simplistic in addressing complex emotional responses.
- The "hopeful skeptic" approach may not always be the best stance, as some situations may require a more optimistic or trusting attitude to foster team morale or to inspire confidence.

The Hidden Power of Doubt and Uncertainty
Shankar Vedantam introduces the idea that doubt, typically seen as a negative trait, can actually be a powerful tool for growth, learning, and better decision-making.
Embracing Doubt for Better Decision-Making
Bobby Parmar, the author of "Radical Doubt," argues that doubt can be leveraged to transform uncertainty into sure-fire success, indicating that it can improve the decision-making process. He discusses the story of General Eisenhower on the eve of D-Day, illustrating how Eisenhower's public confidence was balanced by private doubt, preparing an acceptance of responsibility if the operation were to fail. Parmar himself experienced growth by stepping outside his comfort zone and embracing the uncertainties of a backpacking trip despite personal limitations, viewing it as an opportunity to learn and grow personally.
Parmar describes doubt as beneficial when dealing with complex situations. He suggests that people who focus on getting right answers and who crave certainty tend to dismiss different perspectives, underestimate risks, and become overconfident. He advocates for considering doubt as a productive tool for examining various solutions. Parmar highlights the strategy of "Anomalizing," where noticing early signals of deviation can lead to critical insights, and he discusses the premortem technique as a preventive strategy for identifying potential failures.
Doubt Aids In Exploring Solutions Amid Complexity
Parmar exemplifies good practice by recounting an expedition where instead of pressing forward or giving up when faced with a challenge, he and his students hiked back up a mountain to find the safest route. A study with military officers echoes this, showing that novices often treat intuition as the correct decision, whereas experts use their intuition as a hypothesis, ask questions, and build flexible strategies.
Experiencing Doubt Can Lead To Greater Growth
By pushing himself into uncomfortable situations, like a backpacking trip, Parmar sought to face and learn from doubt and uncertainty. This experience of navigating an uncertain situation led to significant self-reflection and growth over time. He learned valuable lessons about the decision-making process and the avoidance of uncertainty that has shaped his approach to doubt as a resource for better decision-making.

Brain Systems Influence Handling Doubt and Uncertainty
Vedantam and Parmar discuss brain functions related to doubt and uncertainty. The brain has a "pause and piece together" system, which functions to resolve conflicting interpretations and is crucial when we experience doubt.
Acute Stress Overpowers Reflection System
During periods of acute stress, people tend to seek relief. This response can lead people to make impulsive decisions as an increase in protect system activity can overshadow the reflective thought process, hindering effec ...

Clarifications
- "Anomalizing" is a strategy that involves actively looking for and paying attention to early signs or data that do not fit expected patterns or assumptions. It helps decision-makers identify potential problems or opportunities before they become obvious. This approach encourages questioning initial beliefs and adapting plans based on new, unexpected information. By embracing anomalies, individuals can avoid blind spots and improve outcomes in complex situations.
- The premortem technique involves imagining a future failure of a plan and then working backward to identify possible causes. It helps decision-makers anticipate risks and weaknesses before they occur. By envisioning what might go wrong, teams can develop strategies to prevent those failures. This proactive approach improves planning and reduces overconfidence.
- Moral dumbfounding occurs when people have a strong intuitive moral reaction but struggle to provide logical reasons for it. It reveals how emotions often drive moral judgments more than rational thought. This phenomenon shows that people may defend their gut feelings even without clear evidence. It highlights the challenge of making fully reasoned ethical decisions.
- The "pause and piece together" system refers to brain networks involved in reflective thinking and conflict resolution, primarily the prefrontal cortex. This area helps evaluate conflicting information and suppress impulsive reactions to enable thoughtful decision-making. It works by integrating past experiences, current context, and possible outcomes to reduce uncertainty. When functioning well, it supports careful analysis rather than snap judgments.
- Novices often rely on intuition as a final answer, trusting gut feelings without questioning them. Experts treat intuition as an initial hypothesis to test and refine through analysis and evidence. This approach allows experts to remain flexible and adapt strategies based on new information. It helps prevent errors caused by overconfidence or premature conclusions.
- General Dwight D. Eisenhower was the Supreme Allied Commander during World War II, responsible for planning and executing the D-Day invasion on June 6, 1944. This operation was a massive and risky amphibious assault on Nazi-occupied France, crucial for turning the tide of the war in Europe. Eisenhower's decision-making involved balancing immense pressure, uncertainty, and the lives of thousands of soldiers. His private doubt and contingency planning reflected the gravity and unpredictability of the mission.
- The "protect system activity" refers to the brain's automatic response to perceived threats, activating survival mechanisms like fight, flight, or freeze. This system prioritizes immediate safety over thoughtful analysis, triggering stress hormones such as adrenaline. It suppresses the brain's reflective, reasoning functions to enable quick reactions. This shift can impair complex decision-making during acute stress.

Counterarguments
- Doubt can sometimes lead to analysis paralysis, where an individual becomes so overwhelmed by considering all possible outcomes and perspectives that they struggle to make any decision at all.
- In some high-stakes or time-sensitive situations, the luxury of embracing doubt may not be feasible, and decisive action without the opportunity for extensive reflection may be necessary.
- Overemphasis on doubt could potentially undermine confidence in a way that is visible to others, which might erode a leader's ability to inspire and lead effectively.
- The strategy of "Anomalizing" might lead to an excessive focus on minor deviations, causing unnecessary alarm or distraction from the main objectives.
- The premortem technique, while useful, could also foster a negative mindset that is overly focused on failure rather than on the potential for success.
- While experts may use intuition as a hypothesis, this approach may not always be practical in fields where rapid decision-making is critical and there is little time for reflection.
- The idea that experiencing doubt leads to growth assumes that individuals have the psychological resilience to cope with uncertainty, which may not be true for everyone.
- The brain's "pause and piece together" system may not always be beneficial; for example, in cases where a quick decision is needed, this system could hinder the ability to act swiftly.

Strategies For Reducing Defensiveness When Receiving Feedback
Understanding the psychological roots of defensiveness and employing strategies to manage it can lead to more productive conversations and personal growth.
Understanding the Psychological Roots of Defensiveness
Feedback Can Feel Like an Attack on Our Identity
Emily Falk points out that the brain often conflates our identity with our values, causing trouble when we receive feedback because it may feel like a broader judgment of who we are, rather than advice or input. Shankar Vedantam adds that criticism tends to challenge our self-concept, often leading to instinctive rejection.
We Judge Ourselves By Intentions, Others See Actions
Vedantam and Falk discuss how we have access to more information about our intentions and the efforts behind our actions, which may be invisible to others who simply see the results. This discrepancy leads to a defensive reaction to feedback that feels like an attack on our identity.
Techniques For Creating Psychological Distance
Reflecting On Core Values and Purpose
Falk suggests that reflecting on core values, or what psychologists call values affirmation, can offer psychological distance. By focusing on core values, individuals can see that their worth isn't determined by whatever is being critiqued.
Imagining how a Wise, Patient Mentor Would Respond
While not explicitly discussed, Sue's mature handling of criticism could be viewed as an analog to how a wise, patient mentor may respond to feedback. Imagining the reaction of a role model can help individuals adopt qualities of patience or wisdom, as suggested by Falk.
Considering how We Might View the Situation Differently
Falk talks about the strategy of framing feedback as a collaborative problem-solving exercise. By taking on the perspective of others, a more constructive conversation can pivot away from defensiveness. The use of hindsight bias and mental preparation can facilitate a constructive and less emotional response to criticism.
The Power Of Framing Feedback Constructively
Feedback as a Collaborative Problem-Solving Exercise
Falk articulates that thinking about feedback as a team effort towards problem-solving can be beneficial. It turns the process into a mutually supportive action rather than a one-sided critique.

Clarifications
- Values affirmation is a psychological technique where individuals focus on their core personal values to reinforce their sense of self-worth. This process helps separate their identity from specific criticisms, reducing emotional threat. By affirming what truly matters to them, people gain mental space to view feedback more objectively. This distance lowers defensiveness and promotes openness to constructive input.
- The brain links identity and values because values represent what we consider important and define our sense of self. When feedback challenges our actions, it feels like a threat to these core beliefs, triggering a defensive response. This happens because the brain aims to protect a stable self-image essential for psychological security. Thus, criticism can feel like a personal attack rather than neutral information.
- Self-concept is the mental image or perception a person has of themselves, including beliefs, feelings, and thoughts about their identity. It shapes how individuals interpret experiences and feedback, influencing their emotional reactions. A strong, positive self-concept can buffer against negative feedback, while a fragile one may increase defensiveness. Understanding self-concept helps explain why criticism can feel like a personal attack.
- Hindsight bias is the tendency to see events as more predictable after they have happened. When receiving feedback, it can cause people to believe they "should have known better," increasing defensiveness. Recognizing this bias helps individuals understand that mistakes are part of learning, not failures. This awareness promotes a more open and less emotional response to criticism.
- A "hopeful skeptic" is someone who remains open to new ideas or feedback but critically evaluates their validity before accepting them. This approach balances optimism about potential improvement with caution against blindly trusting all input. Practically, it means listening carefully, considering the source and intent, and deciding what is genuinely useful. It helps protect self-esteem while encouraging growth.
- Stories and parables create a safe emotional distance by presenting lessons indirectly, so people don't feel personally attacked. They engage the listener's imagination, allowing self-reflection without direct confrontation. This indirect approach lowers emotional defenses, making it easier to accept new ideas. Additionally, narratives often evoke empathy, helping individuals relate to the message more openly.
- "Garden variety defensiveness" refers to a natural, automatic reaction to protect oneself from perceived criticism or threat. Defensiveness due to manipulation occurs when someone uses feedback strategically to control, undermine, or influence another person for their own benefit. The key difference lies in intent: natural defensiveness is self-protective, while manipulative defensiveness involves external motives. Recognizing this helps in deciding wh ...
Actionables
- Create a feedback journal where you record criticism received, your initial emotional response, and a later, more objective analysis of the feedback. This practice encourages you to separate your emotional reactions from a more rational assessment of the feedback's content. For example, after receiving criticism at work, jot down how it made you feel initially, then revisit the entry a few days later to evaluate the feedback without the emotional charge.
- Develop a "feedback avatar," a fictional character that embodies resilience and objectivity, and imagine how this character would handle the feedback you receive. This strategy helps you to depersonalize criticism and approach it with a mindset geared towards growth and learning. If you're a graphic designer and a client criticizes your work, imagine how your avatar, perhaps a renowned and unflappable designer, would use the critique to refine their art.
- Start a "perspective swap" exercise with a friend or colleague where you share a piece of feedb ...
