US President
Quick Answer
Theodore Roosevelt's IQ was never verified by a standardized test. LifeScore's retrospective estimate is 145+, with a cautious working range of 130–155.
145+ is a broad historiometric estimate based on the surviving record, not a measured IQ score.
Evidence status: Very low confidence. No verified standardized IQ result is cited for this profile. Historical achievement cannot be converted into a precise modern test result; this page separates documented evidence from interpretation.

Historical Context
20th Century was an environment where The Hero-style minds could gain leverage quickly. The structural conditions matched Theodore's strengths.
Key Lessons
Theodore's greatest strength (Vigor and Intellectual curiosity) was also their greatest liability when taken to extremes.
The The Hero archetype tends to succeed in environments that reward bold action and long-term vision, but struggles in environments that demand consensus-building.
One pattern worth noting: Theodore's output was most productive when external constraints forced focus. Without structure, the same traits that enabled greatness sometimes led to overreach.
Modern Parallel
Arnold Schwarzenegger represents the contemporary version of Theodore's psychological profile. The era is different, but the underlying patterns—risk tolerance, work style, social strategy—map closely.
