In this episode of The Science of Leadership, host Tom Collins and co-host Justin Hamrick dive deep into the imperative concept of team cohesion. Using a unique analogy from chemistry, they distinguish between adhesion—where one leader tries to hold a team together—and true cohesion, where team members are joined through mutual interaction and strong relationships.

The discussion explores why "team chemistry" isn't just a sports cliche but a fundamental survival factor in high-stakes fields like medicine and the military. They break down the three pillars that create a unified team and the three consistent patterns that destroy it.

Also, I want to remind listeners about the release of my book, "The Four Stars of Leadership," a culmination of over three years of dedicated work, and I'm confident it will be an immensely interesting and helpful guide on your journey to becoming a better leader.
