Why do smart, experienced leadership teams occasionally make decisions that look obvious in hindsight?

Many leaders believe groupthink happens when people are afraid to speak up or when teams lack diversity. But research from Yale psychologist Irving Janis reveals something far more uncomfortable: Groupthink often appears in the strongest, most trusting teams.

When loyalty, speed, and harmony become priorities, teams may unknowingly stop challenging assumptions—leading to flawed decisions, costly project mistakes, and missed opportunities.

In this episode, we highlight a few powerful takeaways from one of our recommended leadership reads: Victims of Groupthink by Irving L. Janis. Host Bradley Hartmann extracts practical lessons construction leaders can apply immediately to improve team decision-making.

In this episode, you'll learn:

Why high-trust leadership teams are actually more vulnerable to groupthink
