Fifty years after its publication, Norman F. Dixon’s On the Psychology of Military Incompetence remains a sharp critique of how institutions fail. While the book focused on historical British military disasters, its analysis of character flaws in leadership rings true regarding current U.S. defense leadership under Secretary of War Pete Hegseth.
Dixon identifies a specific personality type drawn to military institutions that values outward appearances, rigid hierarchies, and traditional displays of toughness over strategic insight or innovation. He argues that leaders who prize physical prowess and petty regulations often end up in positions where such traits cause catastrophic failures. The critique highlights a pattern of prioritizing loyalty and tradition over the adaptability required in modern conflict.
This dynamic is visible in the current administration’s approach to the ongoing war with Iran. Under Hegseth, the Pentagon has shifted away from professional standards, prioritizing performative displays of strength and strict adherence to internal codes that Dixon once classified as dangerous distractions. By focusing on cultural grievances and internal purges, leadership has struggled to prepare for complex military realities, such as the drone-driven warfare that has become common elsewhere.
Dixon’s work underscores that the qualities that keep an institution functioning during peace are often the exact traits that ensure defeat during war. By favoring conformity and performative masculinity, senior leaders create an environment that punishes dissent and resists technical change. This approach has left the United States unprepared for the evolving nature of global threats, demonstrating that the failure of military leadership is rarely about intelligence, but rather a stubborn commitment to outdated norms.
