Robert McNamara

Robert S. McNamara, recruited from the Ford Motor Company presidency to serve as Secretary of Defense for Kennedy and Johnson, brought corporate operations research to the Pentagon and applied it to Vietnam. Body counts. Kill ratios. Tonnage of bombs. He believed — and the data appeared to support — that the United States was winning. By 1967 he had privately concluded the war was unwinnable; he never said so publicly while in office. Three million Vietnamese died, along with 58,000 Americans. Decades later, in In Retrospect (1995) and the documentary The Fog of War (2003), McNamara described his own pattern with rare candor: he had mistaken precise quantification of the wrong things for understanding of the right things. This is the Expert plateau in its cleanest form: technical mastery as identity, the assumption that disagreement is incompetence, and a fluency in metrics that produces confident catastrophe. Vietnam is what happens when an Expert is given the authority of a Strategist without ever having developed Strategist's tolerance for uncertainty.
