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.
