Every U.S. President Ranked by IQ

Dwight D. Eisenhower’s intelligence came from order, logic, and strategy. A West Point graduate and supreme Allied commander in World War II, he mastered complex logistics and coordination across nations. His disciplined, methodical mind valued clarity over theory, and he excelled at making sound decisions under enormous pressure.

As president, Eisenhower applied that same strategic intelligence to peacetime leadership. He managed the Cold War cautiously, balanced budgets, and oversaw vast infrastructure projects like the interstate highway system. His intellect expressed itself not in rhetoric but in organization, patience, and an engineer’s sense of efficiency and proportion.
