This episode summarizes the dissertation of Dr. Charles Casto, Extreme Crisis Leadership: is there a unified theory of approach to leadership? This text is an in-depth qualitative study of leadership in extreme events, drawing upon interviews and existing literature. It explores key aspects such as situational context, felt emotions, sensemaking, decision-making, and crisis response, examining how these factors influence leadership effectiveness during unpredictable crises. The research aims to identify unique leadership challenges and concepts that emerge in extreme situations, suggesting that non-linear approaches are often required. The study seeks to contribute to theory-building in extreme crisis leadership by analyzing cases like Fukushima and Deepwater Horizon.
