In this profound episode of The Science of Leadership, host Tom Collins is joined by Colonel Lee Ellis (Ret. U.S. Air Force, former Vietnam POW, and author of Leading with Honor). Colonel Ellis spent five years, four months, and two weeks enduring the crucible of adversity in the Hanoi Hilton, forging indelible lessons about character, trust, and honor.

Colonel Ellis defines the honor code as telling the truth, keeping commitments, being ethical, and acting responsibly. He explains that courage is the centerpiece of honor—the willingness to suffer pain and punishment to sustain one's values.

The conversation dives into:

• The Temptation to Compromise: Colonel Ellis identifies the areas where leaders are most likely to fall short on honor: politics, money, and avoiding exposure of mistakes.
• The Power of Debriefing: He highlights the fighter pilot culture of intense debriefs (like those of the Thunderbirds) where leaders must "tell it like it is" and critique themselves and others to correct back quickly.
• Trust and Coherence: Tom Collins shares the science showing that honor restores coherence and builds the psychological safety essential for team performance.
• The Secure Leader: Colonel Ellis shares his model of moving from an anchor of insecurity (fear, shame, guilt) to a state of being secure through courage, commitment, and self-belief.

Colonel Ellis shares gripping personal accounts of torture and resilience in captivity, underscoring the lesson that while living with honor may involve suffering, it ultimately leads to healthier, more successful lives.

In this episode of The Science of Leadership, host Tom Collins is joined by retired U.S. Air Force General Ellen Pawlikowski (Ph.D. in Chemical Engineering, former Commander of Air Force Materiel Command) to dissect the often-misunderstood component of Caring For Your People.

General Pawlikowski explains that true leadership Caring For is not "soft" or "sentimental" but rather a strategic necessity integrated into Courage, Competence, Commitment, and Compassion. She states, "I don't succeed if you don't succeed."

The conversation highlights that a leader's core responsibility is to be the Chief Obstacle Remover. General Pawlikowski shares a powerful example from Air Force Materiel Command, where aging IT infrastructure threatened to leave $60 billion unspent and required her to intervene personally with the Chief of Staff.

Key Takeaways:

• Caring is Preventative Maintenance: Leaders must invest in basic needs, tools, and training, as ignoring small problems (like unit confusion or outdated software) can lead to catastrophic failures.
• Understanding the Whole Person: Compassion means acknowledging that people have lives outside of work (family, elders, personal issues). Failure to allow time for these distractions leads to reduced cognitive energy and increased mistakes.
• Science of Care: Research confirms that when leaders care tangibly and structurally, morale, trust, and productivity all increase.

The General shares practical steps and an essential four-question framework for leaders to ask their teams to identify hidden obstacles and leverage existing expertise.

In this episode of The Science of Leadership, host Tom Collins is joined by retired Lieutenant General Scott Dingle, the 45th Surgeon General of the U.S. Army, to explore the vital concept of the "Ever Learner"—a leader committed to continuous growth and adaptability.

General Dingle defines the Ever Learner as someone with the mindset and practice of continuously seeking knowledge, skills, and experience without stop. Both he and Tom emphasize that leadership is a journey, not a destination. General Dingle shares two powerful stories from his career—starting as a "Butterball" Second Lieutenant to serving as a Three-Star General—that illustrate the continuous need to adapt to chaos, crisis, and unexpected turns.

The hosts emphasize that settling for "good enough" allows adversaries (whether a competitor, a disease, or Ivan Drago) to win because they "aren't taking a day off." Leaders who stop evolving become extinct.

Key Takeaways for Becoming an Ever Learner:

• Adopt a Growth Mindset: Reframe "I don't know it" as "I don't know that yet," seeing challenges as opportunities to improve.
• Seek Feedback: Actively ask peers and those you lead for candid input, and receive it graciously.
• Reflect Regularly: Follow the example of leaders who review their experiences daily to extract lessons and become better tomorrow.
• Practice Humility: Acknowledge what you don't know and surround yourself with mentors and diverse voices to combat narrow perspective.

The scientific data supports this: leaders who model curiosity and learning foster psychological safety, resilience, performance, and organizational creativity throughout their teams.

While conventional wisdom places the leader at the top, Tom Collins and Justin Hamrick challenge this view to explore Leading Up—the art of influencing those in authority above you, often without holding a formal leadership position. This concept is vital because success often depends on bringing ground-level insight to the ultimate decision-makers.

The hosts discuss why leading up is a moral imperative for the success of any organization, especially since all human organizations inevitably place "wrong people" in some leadership roles. Leading up requires humility and sacrificial service to the larger mission, even when there's a risk of the leader taking credit for your ideas.

Key Takeaways for Leading Up:

• Be a Good Lieutenant: Help your leader do their job as well as possible.

• See Them as an Ally: View your boss as a partner, not an adversary.

• Bring Solutions, Not Just Complaints: Come with proposed solutions or evidence of thoughtful analysis, especially for issues that affect the entire organization, not just your silo.

Key Takeaways for Encouraging Leading Up (If you are the Boss):

• Set Clear Expectations: Explicitly state that you expect and need your team to speak up and lead up.

• Never Respond Negatively: When dissenting information is brought forward, take it graciously, say "thank you," and commit to looking into it. Punishing honesty will quickly ensure you stop receiving information crucial for wise decisions.

In this episode of The Science of Leadership, host Tom Collins is joined by retired U.S. Marine Corps Sergeant Major Mario Fields, a combat veteran, speaker, and founder of Still Serving, Inc. They explore the core leadership force of empowerment, defining it as setting conditions for success for those you lead.

Sergeant Major Fields emphasizes that empowerment must start with trusting yourself first to acknowledge and mitigate personal biases, and then extending that trust to others. They frame empowerment as trust in action , arguing that true leadership is about creating capability in others, which includes granting the freedom—and opportunity—to fail and learn from mistakes.

The conversation dives into what hinders empowerment:

• Micromanagement: Often stems from a leader's failure to hire, train, or clarify expectations effectively.
• The Problem at the Top: Sergeant Major Fields asserts that poor unit or company performance rarely starts with junior folks; the problems begin with the leadership. Leaders must be amenable to feedback to fix their behaviors.

Key Scientific Takeaways:

• Empowerment multiplies leadership and avoids decision bottlenecks.

• The data supports that empowering behaviors (sharing power, encouraging autonomy) predict higher job satisfaction, creativity, and performance.

• Leaders must understand that 93% of communication is nonverbal and tone , which either validates the stated words or disempowers the team.

Practical Tip: Mario recommends leaders and their teams use the Dr. Holland RIASEC codes to understand personality wiring, ensuring people are put in roles that enhance their natural abilities. The episode closes with the wisdom that successful leaders all figure out how to identify and empower talent.

In this episode of The Science of Leadership, host Tom Collins, MD, and co-host Justin Hamrick dissect the powerful, often misunderstood, concept of servant leadership. The conversation addresses the notion that to succeed, leaders must "step on other people," arguing instead that sacrificial leadership—prioritizing follower growth and well-being over personal glory—is the true path to organizational success.

The hosts differentiate this leadership style across contexts, from the military maxim of "officers eat last" to a CEO forgoing a bonus for frontline jobs. They emphasize that great leaders lead from a position of responsibility, not privilege.

Key insights from the science of leadership include:

• The Win-Win Phenomenon: Giving credit away is not a zero-sum game; it returns more influence and effectiveness to the leader.
• Scientific Validation: Servant leadership is strongly associated with increased trust, loyalty, job performance, and follower well-being.
• Neuroscience: Acts of selflessness activate mirror neurons in followers, fostering emotional resonance and a shared sense of purpose.

The episode concludes with actionable take-home points for adopting the "leader as servant" mindset , including: shielding in public, coaching in private , and making visible gestures of sacrifice that are authentic, not performative.

In this insightful episode of The Science of Leadership, host Tom Collins, MD, talks with Bob Tiede, author of Success Unlocked: The Transformative Power of Questions and long-time campus ministry leader. They explore the core idea of leading with questions, which Bob confesses changed him from a "benevolent dictator" into a far more effective leader.

Bob argues that leading with questions is the "hidden symbol" of effective leadership. When leaders ask and genuinely listen to their staff, several transformative things happen:

• Better Ideas: There is a probability that a staff member will have an idea better than the leader's.
• Ownership and Motivation: Staff members are empowered to execute their own ideas, leading to 1000% effort and ownership.
• Trust and Respect: Leaders build immense trust by showing honesty and admitting when they don't know the answer, then asking, "How could we find out the answer?".

The episode features two foundational principles and simple tools:

1. The Gold Nugget Method: Bob explains that research shows people instinctively roll out a "safe answer" first, and it's not until the third and fourth question ("What else? What else?") that you reach their best thought or "gold nugget".
2. The Eight-Second Rule: To listen effectively, leaders must wait 8 seconds before jumping in, as the average person only waits 2-3 seconds. This intentional silence ensures that people feel heard and fully share their ideas.

Bob shares compelling real-world examples, including how Navy Captain Michael Abrashoff transformed the morale of the USS Benfold from "worst to first" simply by conducting one-on-one meetings and asking three powerful questions , and how asking the frontline staff at Walt Disney World Laundry Services slashed employee turnover.

In this electrifying episode of The Science of Leadership, host Tom Collins welcomes retired Navy two-star Admiral Mike Manazir—Top Gun fighter pilot, former commander of the USS Nimitz, and author of Learn to Lead to Win. They explore the foundational leadership concept of trust, revealing why it's not just a soft skill, but an operational necessity, especially in high-stakes environments.

Admiral Manazir shares that an effective leader needs to accomplish only two things: ensure every team member feels valued and feels part of something bigger than themselves. He asserts that trust is the core of this human connection, and a leader must be the first person to extend that trust. This extension, he notes, initiates the Pygmalion Effect, inspiring the team to be trustworthy in return.

The Admiral brings this concept to life with two incredible, visceral "sea stories":

The Golden Knights Jump: He recounts the paralyzing fear he felt at the door of a plane and how the total competence and trust he had in his Delta Force jump instructors instantly took the fear away.

The High-Stakes Landing: He shares the story of a catastrophic partial ejection aboard the USS Abraham Lincoln and how the success of the emergency landing hinged on the mutual trust between the pilot, the ship's captain, and the Landing Signal Officer (himself).

The episode also delves into the science, explaining that trust is the foundational element that enables psychological safety. Admiral Manazir offers practical advice, emphasizing that delegation must be the primary action for extending trust—tell your team the what and the when, but never the how. He ultimately concludes that if a leader wants to be trusted, they must first be trustworthy themselves.
