Shownotes

Confidence is often a prized trait in leadership, but what happens when that confidence isn't backed by competence? In today’s episode, we discuss the allure of overconfidence, examining how it can cloud judgment, mislead hiring decisions, and distort organizational culture. 



Drawing on real-world examples from Silicon Valley and two high-profile leaders, we examine how unchecked overconfidence can lead to catastrophic outcomes for both individuals and organizations. You’ll learn to spot the signs of overconfidence before it’s too late. 

I challenge you to reflect on your leadership decisions and the teams you build. Are you rewarding those with the loudest voices or those with proven results? Join me as we explore how to navigate the overconfidence trap and make decisions that foster true competence, not just charisma.


In this episode:

- The social power of overconfidence

- Real-life case studies: Elizabeth Holmes & Adam Neumann

- The psychology behind overconfidence

- Practical tips for leaders to evaluate overconfidence
