Warren Buffett, the renowned chairman and CEO of Berkshire Hathaway (BRK.B) (BRK.A), has long been celebrated for his disciplined, value-driven investment strategy and his pragmatic approach to business leadership. Every year, the “Oracle of Omaha” pens an extensive letter to shareholders, detailing the state of the company, which is packed with vital knowledge for both aspiring and seasoned investors.
In his most recent 2024 shareholders' letter, Buffett offered a candid reflection on personnel decisions. “A decent batting average in personnel decisions is all that can be hoped for. The cardinal sin is delaying the correction of mistakes or what Charlie Munger called ‘thumb-sucking,’” Buffett said. He continued, “Problems, he would tell me, cannot be wished away. They require action, however uncomfortable that may be.”

This statement encapsulates a central tenet of Buffett’s management philosophy: while perfection in leadership decisions is unattainable, the real failure lies in avoiding or postponing necessary corrective actions. This insight is deeply rooted in the culture of Berkshire Hathaway, shaped over decades by Buffett’s partnership with the late Charlie Munger, his longtime business partner.
Berkshire’s approach to corporate governance has always prioritized transparency, accountability, and the empowerment of talented managers. Their strategy involves identifying exceptional leaders, granting them autonomy, and minimizing interference — a model that has yielded significant returns for Berkshire’s diverse portfolio of companies. Yet, as Buffett’s quote highlights, even the best systems encounter personnel missteps. The key, according to Buffett, is to address these issues promptly rather than allowing discomfort or indecision to prolong problems.
The late Charlie Munger’s influence on Buffett extended beyond investment strategy to decision-making frameworks. Munger championed the use of mental models and advocated for a multidisciplinary approach to problem-solving, which helped Berkshire avoid many common corporate pitfalls. He also stressed the importance of staying within one’s circle of competence and acting decisively when mistakes became apparent. This mindset is echoed in Buffett’s warning against “thumb-sucking” — a metaphor for indecision or wishful thinking in the face of clear problems.
