"e;The Body Count Lie - Why measuring the wrong thing leads to losing the war"e; analyzes the "e;McNamara Fallacy"e; (or Quantitative Fallacy). Robert McNamara, US Secretary of Defense during the Vietnam War, was a genius of data. He believed everything could be managed with spreadsheets. He measured success by "e;body count"e;-the number of enemy soldiers killed. If the number went up, the US was winning. Author Robert Count explains the fatal flaw: The data ignored the "e;unmeasurables"e; like vietnamese morale, the desire for independence, and the corruption of the South Vietnamese government. Worse, the metric created an incentive for soldiers to kill civilians to inflate the count. "e;The Body Count Lie"e; is a warning for the modern data-driven world. It argues that relying solely on what can be easily counted (likes, profits, test scores) while ignoring what really matters (quality, ethics, morale) inevitably leads to disaster.
