Mindset Neuroscience Podcast: "Your brain doesn’t do reality – it does probability: And self-understanding is how we update the code"

Host: Stefanie Faye
Guest: Dr. Nicholas Wright, neuroscientist and advisor on decision-making under pressure
Date: December 30, 2025

Episode Overview

This episode delves into how our brains interpret reality, not by directly perceiving it, but by constructing probabilistic models based on past experiences. Stefanie Faye and Dr. Nicholas Wright explore how understanding the brain's predictive nature can enhance self-understanding, wisdom, and collective intelligence—crucial not only for high-stakes strategy but also for daily relationships, learning, and resilience. Dr. Wright introduces the RAF framework (Reality, Anticipation, Flexibility) and discusses how increasing our awareness of the brain’s modeling can help us update our “code” and act more wisely, both individually and collectively.

Key Discussion Points & Insights

1. Dr. Nicholas Wright’s Journey & Mission

[06:03]

• Dr. Wright began as a neurology doctor, became fascinated by brain science, and transitioned into research using functional brain imaging and computational techniques to understand decision-making.
• He applied insights from neuroscience to real-world contexts, especially to prevent and respond wisely to conflict and insecurity.
• His work includes advising the Pentagon for over a decade: “What you want to do is influence others to prevent a nuclear war from happening… How can you control escalation?”
  — Dr. Nicholas Wright [07:12]

2. How the Brain Constructs Reality: The Model Framework

[10:03]

• The brain’s core function is to connect sensory inputs to actions for achieving goals—every organism’s brain operates this way.
• Animals have simple models (e.g., pain reflexes); humans have complex, layered models:
  • Spatial navigation: “There are maps literally in [the hippocampal-entorhinal cortex]… We’ve shown this in humans. That’s how we navigate the world.” [12:20]
  • Modeling others: Ability to predict others’ behavior (“simulate Stefanie in my head”).
  • Self-modeling: The frontal pole, uniquely developed in humans, enables us to “think about our own thinking” and “ask how certain am I, when should I change my mind?”
    — Dr. Nicholas Wright [13:58]
• All these models form an “orchestra” in the brain to help us navigate the world and make wiser choices through self-reflection.

3. The Power—and Pitfalls—of Models

[15:43]

• Our models help us simplify and manage an overwhelming world—“It’s absolutely remarkable that we can function at all.”
• Yet, models can cause bias and misunderstanding, especially in social contexts: labeling individuals/groups based on prior assumptions.
• “Any medicine that can help can also harm… We have to be aware of how our models work.” [16:35]
• Wisdom requires pausing, reflecting, and questioning the certainty and completeness of one’s model: “People can be clever, but not very wise. Wisdom is about stopping and reflecting and asking yourself, for example, how certain am I about this?”
  — Dr. Nicholas Wright [18:24]

4. Practical Strategies for Gaining Perspective and Wisdom

[20:42]

• Use perspective-taking—see yourself as a “third person.”
• Association cortex supports this perspective; three main brain areas are involved in perspective-taking (“thinking”).
• Practical tools:
  • Imagine how you’d advise a colleague (“third-person project planning”).
  • Seek criticism and diverse viewpoints—Churchill “deliberately chose as his chief military advisor…someone who would argue with him.” [23:40]
  • AI tools (e.g., through IARPA) are emerging to provide feedback and critique.

5. Prediction Error: How We Update Our Models

[25:46; 27:05]

• The brain is designed not to mirror reality, but to build and manage models that must be anchored in reality.
• We update models when confronted with “prediction errors”—when the world violates our expectations.
• “Our models are constantly making predictions… We have to change our models when those predictions are wrong… By explicitly doing that, thinking about our own thinking, we can make better judgments and update our models of the world better.”
  — Dr. Nicholas Wright [29:08]
• Encouragement to seek out environments and information that “poke holes” in our usual models, broadening understanding (e.g., Mandela studying in prison, Eisenhower’s broad education [31:30]).

6. Cultivating Openness and Self-Curated Inputs

[33:22]

• Intentionally choosing diverse, challenging, or unfamiliar information helps keep models flexible and accurate.
• “If Eisenhower can do that as a junior officer in Panama and Mandela can do it… we can probably do it in our lives, even when it seems like we’re overwhelmed by TikTok or Twitter…”
  — Dr. Nicholas Wright [32:32]
• Self-knowledge and collective self-reflection are means not just of survival, but of human flourishing.

7. Human Nature, Conflict, and Deep Optimism

[33:53]

• Dr. Wright’s research acknowledges the reality of human conflict but insists that self-knowledge always includes reasons for optimism.
• “There is no aspect of self-knowledge about humans that doesn’t also contain reasons for optimism. Yes, for example, we have the capacity to lie and deceive… but that can often be used for good, [as] resistance heroes who lied… to save hundreds of thousands…”
  — Dr. Nicholas Wright [34:25]
• Reconciliation and creativity are as much a part of humanity as conflict. Examples: Post-WWII Germany, American and Chinese rapprochement.

8. Reflection, Systems Thinking, and Real-World Application

[36:59; 38:00]

• Reflection doesn’t mean endless contemplation—small moments and intentional awareness are enough to nudge growth.
• “We can have better understanding of where we are ignorant…we can curate the knowledge coming into ourselves… Those are practical things.” [39:29]
• Take time to “stop and reflect,” just as Churchill did. Even micro-moments of reflection during daily life build brain connectivity and support complex, wise action.
• Seek not just more knowledge, but more connections and nuance—wisdom is about connecting and integrating.

9. The Brain’s Unique Human Capacity: Self-Reflection

[44:32; 45:46]

• The ability to “think about our own thinking”—centered in the frontal pole—is what makes us distinctly human.
• “This ability to think about our own thinking is probably…the most remarkable thing we can do as humans. Every now and again we can make corrections that can make all the difference…”
  — Dr. Nicholas Wright [46:28]

10. Reasons for Optimism in a Troubled World

[47:53]

• Despite widespread pessimism, we live in “a wonderful part of history.”
• Even in settings like the Pentagon or major military commands, Dr. Wright encounters thoughtful, reflective leaders.
• “I think we can, through self-knowledge of why we fight wars, why we lose and win wars, we really can build a more peaceful world through self-knowledge. And that really does make me optimistic.”
  — Dr. Nicholas Wright [50:10]
• Each generation stands on the shoulders of the previous—“My children hopefully will know more than me…And that… is another reason to be very optimistic about the future.” [51:24]

Notable Quotes and Memorable Moments

• On Wisdom:
  “Wisdom is seeing the bigger picture about ourselves in the world so that we can choose actions that help us live better.”
  — Dr. Nicholas Wright [21:50]

• On Models:
  “What we end up with is an orchestra—not one model, but in our brain, an orchestra of models… including to make wiser choices.”
  — Dr. Nicholas Wright [15:24]

• On Receiving Critique:
  “If you present your ideas to others, they can interrogate them… It’s always easier to see nonsense when other people are talking than when you’re talking yourself.”
  — Dr. Nicholas Wright [23:30]

• On Updating Models:
  “We have to change our models. We have to be linked to reality. We have to change our models. And we have to do that throughout our lives.”
  — Dr. Nicholas Wright [29:48]

• On Human Nature and Optimism:
  “There is no aspect of self-knowledge about humans that doesn’t also contain reasons for optimism…In victory, magnanimity.”
  — Dr. Nicholas Wright [34:23, 35:56]

• On Self-Reflection:
  “The most remarkable thing we can do as humans [is] explicitly think about our own thinking… Every now and again we can make those corrections that can make all the difference…”
  — Dr. Nicholas Wright [46:40]
