547: How to Master Uncertainty. With (Ret) SEAL Commander, Rich Diviney

Moving horizons is a strategy to address fear and overwhelm by breaking down large challenges into smaller, actionable, and achievable objectives. This practice draws upon how the brain processes uncertainty and rewards, harnessing neurobiology to build momentum and resilience in demanding situations.

Fear From Uncertainty and Anxiety Can Be Mitigated By Managing Them

Fear, according to Rich Diviney, arises from the combination of uncertainty and anxiety. Either state alone does not necessarily induce fear; for example, one can feel anxiety about a presentation while being certain about the content, or feel uncertain about a surprise without fear, as seen in children anticipating gifts. The real inhibitory force comes when both uncertainty and anxiety exist together. Jocko Willink observes that people often become anxious by worrying about hypothetical scenarios, rather than focusing on their current situation or mission. This future-oriented thinking fuels fear by piling imagined outcomes upon uncertainty.

Diviney explains that the brain seeks three elements to minimize uncertainty in any situation: duration (how long an ordeal will last), pathway (the route or steps to resolve the situation), and outcome (what the result will be). Lacking information about any of these triggers stress. For example, with a simple illness like strep throat, we know the pathway (take antibiotics) and the likely outcome (recovery), leaving only the duration uncertain, so stress is mild. With something like the flu, there may be no clear pathway or duration, only an outcome—which increases stress. With something wholly novel and threatening (such as COVID-19 at its onset), duration, pathway, and outcome were all unknown, causing maximal stress and fear.

To mitigate fear, the key is to reduce either uncertainty, anxiety, or both. That means providing answers about duration, pathway, or outcome—effectively closing what Diviney calls the “uncertainty cone”—and using physiological tools like breathwork to manage anxiety.

Moving Horizons Provides Certainty By Focusing On Achievable Objectives

Moving horizons is a neurological method for generating certainty in the present by setting short-term, achievable objectives. Diviney details experiences from Navy SEAL training: instead of thinking about surviving all of Hell Week, he would focus on just reaching the end of a sand berm, or counting out the next ten waves in the surf. This process involves defining a near-term boundary—the “horizon”—and working toward it. Upon reaching it, a new horizon is set. Each completed horizon delivers a sense of mastery and closure, generating a reward in the brain and building momentum to persist through further challenges.

This strategy applies to civilian life as well: whether answering emails one at a time or incrementally building up to a fitness goal by walking to the mailbox, small, defined targets anchor certainty. Focused effort on present actions prevents spiraling worry about distant, hypothetical situations.

Breaking Big Goals Into Smaller Segments Creates Manageable Targets for the Brain, Offering Relief and Momentum

Breaking down large objectives into manageable horizons relieves the mind. Diviney explains that focusing on a concrete, achievable task creates a sense of certainty and allows the brain to register a reward through [restricted term]. Once the immediate horizon is achieved, the next objective can be set, repeating the cycle. Jocko Willink likens this to focusing on the “front sight” rather than the distant target when shooting: when the ultimate goal feels too far, shift to immediate, attainable steps.

Horizon Should Be Challenging yet Attainable to Maintain [restricted term], Adjustable to Individual Capacity

For moving horizons to work, horizons must neither be too ambitious nor too modest. A horizon that is too far out will deplete [restricted term] supplies before success, making it likely that motivation will collapse. Conversely, making goals too easy provides little to no reward, failing to generate momentum. The right horizon triggers a [restricted term] response that both rewards achievement and fuels further pursuit. Diviney and Willink stress that this is subjective—each person and each situation demands a personally adjusted horizon. If a chosen objective feels overwhelming or too distant, pull the horizon closer; if it feels trivial, stretch it slightly out of the comfort zone.

Dynamic adjustment is key. Diviney notes that those who excel in Navy SEAL training are the ones who continually recalibrate their horizons, adapting as conditions change. Instructors intentionally unsettle trainees by moving timelines and tasks, forcing them to learn to set their own psychological horizons. Adaptation, not perfectionism, is the real goal.

[restricted term] Fuels Goal Pursuit, Depletes With Distant Goals, Lacks Impact With Modest Ones

Success with moving horizons depends on managing the brain’s [restricted term] system. [restricted term] is released during the pursuit of goals, not just during pleasure. If the final target is too remote, [restricted term] runs out long before arrival; if it’s too close or easy, the reward is insufficient. Each meaningful horizon achieved offers a “[restricted term] hit,” sustaining motivation and engagement. Importantly, talking about big goals can give a false rewar ...

Rich Diviney and Jocko Willink emphasize that understanding one's ranked attributes and core identity is essential for predicting and adjusting behavior, especially under stress, and for assembling highly effective teams.

Ranked Traits Define Individuals' Raw, Unfiltered State, Especially Under Stress

36 Unique Ranked Attributes per Person

Diviney introduces a framework in which each individual possesses 36 ranked attributes. These rankings reveal a person’s most fundamental behavioral tendencies and become especially apparent under pressure. The ranking does not mean that someone entirely lacks an attribute—for instance, being ranked last in humor does not mean the person cannot be funny, only that humor will not be their default, especially in high-stress situations.

Attributes Prioritize Behavior: Lower Patience Ranks Prioritize Other Behaviors Under Pressure

Attribute rankings dictate which traits drive behavior unconsciously when someone is stressed or challenged. For example, someone ranked high in decisiveness but low in patience will make quick decisions in a crisis, possibly at the cost of thorough consideration. Attribute rankings thus determine the order and likelihood of drawing on particular qualities, while lower-ranked traits require deliberate effort and energy to access, especially under stress.

Attribute Rankings Include Blind Spots and Advantages: High Decisiveness but Low Patience Leads To Rapid Decisions With a Risk of Impulsive Mistakes

Each attribute’s position has advantages and potential blind spots. High decisiveness with low patience means someone takes fast action, which is beneficial for avoiding delays. However, the same combination can result in impulsive mistakes. Complementary relationships, such as one partner who is low in patience and another high, allow for balanced teamwork where one prevents procrastination and the other curbs impulsivity. Recognizing that both high and low rankings contribute value and risk is fundamental.

Adjusting Attributes Requires Effort and Energy, Especially Under Stress

Although individuals can “dial up” or “dial down” attributes situationally, doing so requires conscious effort. For instance, someone who usually jokes may have to restrain themselves (“dialing down” humor) if it’s inappropriate. However, sustaining non-preferred attributes is energetically expensive, and in stressful moments, people revert to their core stack. Developing lower attributes is possible through deliberate self-development, but is not always necessary or beneficial; pushing to change an attribute can drain energy and reduce effectiveness.

Teams Succeed When Members Understand Attributes, Creating Natural Roles and Dynamic Leadership

High-Performing Teams Resemble Puzzle Pieces, With Members Balancing Roles By Pairing Attributes, Such As Matching High-Courage With Low-courage For Risk Assessment

Willink and Diviney agree that high-performing teams operate like well-designed puzzles. Diverse attribute rankings allow members to balance and complement each other. For instance, pairing a high-courage individual (who might accept risk readily) with a low-courage team member (who will highlight dangers) ensures more nuanced decisions. Introverts and extroverts, or those high and low in patience, working together enable a richer range of responses to challenges, with each member stepping up where their strength is needed.

Attribute Rankings: Aligning Strengths With Roles to Avoid Misalignment and Underperformance

Team performance can drop when roles do not align with individuals’ attribute stacks. Diviney provides examples, such as a sailor misassigned to a bad-fit section until her attributes led to a successful role change. Assigning roles by attribute fit, not just skills or position, avoids labeling people as “low performers” due to mismatch rather than true ability.

Navy Seals Assign Roles By Recognizing Attributes: Robust Members For Machine-Guns, Situational Awareness For Point-Man, High Cognition For Communication

Among Navy SEALs, this philosophy shapes team roles. Robust “F-350” types are given machine guns, fast-reacting “Ferraris” might take point in patrols, and those with high cognitive attributes manage communications. Sometimes initial assignments are based on quick judgments of attribute fit, recognizing natural tendencies to fill certain roles. Skills can be taught, but the underlying attr ...

Leaders cultivate high-performing teams by embodying and modeling four crucial elements of trust, showing authentic vulnerability, and understanding that real influence comes from followership—not mere formal authority.

Trust Consists Of Four Behaviors Leaders Must Demonstrate

Competence, Consistency, Character, and Compassion: Explained

Rich Diviney and Jocko Willink define trust through four elements: competence, consistency, character, and compassion. Competence is “do the thing right”—demonstrating skill and capability. Consistency is “do the thing right over time”—showing reliability in actions. Character is “do the right thing”—acting ethically even under pressure. Compassion is “do the right thing because you care about me as a human being”—showing genuine concern for people, not just results. Diviney stresses all four factors are essential; competence and consistency alone are insufficient for durable trust if character and compassion are lacking.

Establish Trust Through Example and Mutual Investment

Trust is established through leaders’ behaviors, not titles. Leaders must “go first” by embodying the values they want to see: offering trust, listening, respect, influence, and care to others, which encourages mutual investment and reciprocity. Diviney and Willink agree that trust is an active, generative process requiring leaders to risk vulnerability and model accountability, rather than waiting for proof from others.

Overemphasis on Competence Over Character Erodes Trust

Diviney cautions that in high-performance contexts like the Navy SEALs, competence and consistency sometimes overshadow character and compassion, risking fragile or transactional trust. True, enduring trust arises only when all four elements are present and actively cultivated.

Leaders Must Show Vulnerability, Trust, and Accountability For Team Psychological Permission

Authentic Vulnerability Boosts Followership: Acknowledging Weaknesses and Knowledge Gaps Increases Humility and Reduces Fear of Judgment, Contrary to Fears Of Undermining Authority

Willink and Diviney stress that authentic vulnerability is critical for leadership. Leaders must openly acknowledge weaknesses and knowledge gaps. Rather than eroding authority, this humility increases team respect and psychological permission for others to do the same, reducing fear of judgment and boosting willingness to follow. Team members who refuse to admit fault or lack humility are rejected by high-performing teams.

Environments Foster Humility in High-Stakes Military Contexts

Diviney points out that certain environments, such as SEAL training and operational settings, inherently cultivate humility in leaders and team members. The ocean, extreme heights, or other high-risk situations remind individuals of their limitations daily, enforcing authentic humility.

Delegating Responsibility Without Accountability Reflects Leadership Failure

Leaders must delegate respons ...

Understanding and managing autonomic arousal is essential for maintaining cognitive function and composure in stressful situations. Jocko Willink and Rich Diviney highlight how the body’s natural stress response can become a tool for improved performance—or, if left unchecked, result in cognitive “decision collapse.”

Autonomic Arousal Boosts Threat Response, Excessive Arousal Causes Amygdala Hijack and Decision Collapse

Arousal is an evolutionary mechanism—when the body perceives a threat, it offers a surge of alertness and energy. This autonomic arousal boosts the ability to react quickly, enabling vital actions like jumping out of the way of a car or running from danger. However, in excessive amounts, this beneficial reaction turns into a liability.

Arousal Redirects Blood and Oxygen, Causing Impulsive Actions

When arousal increases, blood and oxygen flow shift away from the prefrontal cortex, the seat of rational thinking, toward the amygdala and the limbic system. As a result, conscious decision-making is replaced by impulsive, reflexive actions—a state called amygdala hijack. People often react suddenly to stress and later find they can’t clearly recall their actions during the event. This automatic response, though crucial for survival in emergencies, bypasses higher thought processes.

System Evolved For Threats Creates Dysfunction in Modern Deliberative Situations

Diviney points out that this system was essential when real threats were common, but in the modern world—where most challenges require deliberation and complex decision-making—overactive arousal is counterproductive. The “hijacked” brain favors fast, unthinking action over thoughtful reflection, hurting performance in meetings, public speaking, or crisis management.

Core Competency Training For Automaticity During Amygdala Hijack

To mitigate the downsides of amygdala hijack, training and repetition are essential. In high-stress professions like the military, individuals drill core competencies—“shoot, move, and communicate”—until they become automatic, ensuring that even under overload, reflexive actions will be effective. This kind of training builds “muscle memory,” allowing necessary procedures to happen without conscious thought during high-stress situations.

Breathing Techniques Modulate Arousal and Activate Prefrontal Cortex

Effective stress management involves techniques to consciously rebalance the brain’s blood flow and restore higher-order thinking.

Breathing Patterns: Quick Inhales Increase Arousal, Extended Exhales Decrease It

One of the most immediate tools for modulating arousal is conscious breathing. Quick, sharp inhales—oxygen-dominated, as seen in the Wim Hof method—can increase arousal, making them useful for energizing before intense activity. In contrast, extending the exhale (longer out-breaths) brings down arousal levels, steadying physiological responses.

Box Breathing & 4-7-8 Techniques For Managing Arousal Without Equipment

Box breathing and 4-7-8 breathing are structured techniques that can be used anywhere to regain composure. Box breathing involves slow, rhythmic inhalation, holding, exhalation, and another hold, while the 4-7-8 method times each breath component precisely. These techniques help keep the frontal lobe engaged, providing space for conscious decision-making rather than instant reactivity.

Yawning Activates Calming Mechanisms Before Stress, Allowing It to Be a Stress-Management Tool

Yawning, or the “psychological sigh,” is another tool for regulating arousal. Yawning often happens before stressful events—like before a parachute jump—and serves to activate the trigeminal nerve, which connects to the vagus nerve, inducing calm. This mechanism primes the body for stress by increasing oxygen intake and activating systems that counterbalance panic.

Visual Tools Enhance Calmness, Awareness, Reaction Time

Physiological arousal not only changes breathing but also vision. Managing the field of visual focus ca ...

Team culture is the collective identity that guides group behavior and decision-making, especially in situations of high uncertainty or stress. Jocko Willink and Rich Diviney stress that when core standards and "I am" statements are internalized, teams operate with decentralized command, fostering accountability, effective action, and resilience.

Culture Represents Shared "I Am" Statements Defining Behaviors and Enabling Independent Decision-Making

Personal and group identities serve as the subconscious source of action, especially under stress. Willink explains that deep uncertainty strips away surface layers—ideals, preferences, even personalities—revealing core identities, the "I ams," that direct instincts and behaviors.

Decentralized command thrives when core standards are internalized. In families or organizations, embedded culture means members know how to behave without constant supervision. Willink observes that children excel academically and obey family standards not because they are told to, but because those expectations are embedded in the family culture.

Effective cultural statements are concise, memorable, and behavior-anchored. Diviney critiques complex ethos statements, such as the Navy SEAL Ethos, for being too hard to remember under pressure. Short, potent mantras like "I will never quit" or "I will not let down my teammates" prove more effective. These distilled "I am" statements provide clear, actionable guidance during high-stress decision points. Willink highlights how the Marine Corps reinforces identity through rituals, embedding standards so deeply that they guide behavior even in the absence of command.

Effective Team Identities Need Intentional, Collective Design for Genuine Adoption and Persistence

A team's identity must emerge through collective intent, not top-down declaration. Diviney shares that identity statements he designed as a commander were effective while he was present, but failed to endure after his departure since they weren't created together with the team members. Only when teams design their "I am" statements collectively does the identity persist, belonging to the group rather than an individual leader.

Willink argues that every team—be it professional, military, or even youth—must work together to establish codes and identity. He advocates for engaging individuals, especially youth, in crafting their own codes with examples and frameworks, ensuring standards are personally meaningful and enduring. Living without a code, he warns, is rudderless.

Establishing identity demands effort and regular engagement. Diviney emphasizes that selection processes, such as for the SEALs, are designed to filter for individuals who naturally align with the desired values and behaviors. Teams thrive when every member fits the shared culture, as forcing misaligned individuals leads to toxicity, regardless of their personal merits or skills.

Teams Enforce Standards When Leadership Fosters a Culture of Group Accountability

Self-governance flourishes in high-performing teams bound by shared identity. Willink recalls that as a platoon commander, he rarely needed to intervene when someone was late or unprepared—the team policed itself, correcting peers before leaders needed to act. This group accountability protects the team’s identity, as members are often more motivated to uphold standards than to avoid momentary discomfort.

Leaders set expectations, but successful group culture empowers members to self-enforce standards. Platoons correct issues internally—like tardiness or missing gear—because upholding shared values outweighs personal convenience. Willink offers concrete examples: violating rules like no drinking led to immediate consequences to protect the mission, and individuals not ready for deployment were held accountable for self-sabotage, reinforcing the expectation that every member contributes to readiness.

Importantly, the line between perseverance, mission accomplishment, and caring for teammates must be respected. Loyalty can become dangerous if it leads to cover-ups or inadequate preparation, as Diviney notes, refere ...
