Quick Answer
Bill Gates's IQ was never verified by a standardized test. LifeScore's retrospective estimate is 155+, with a cautious working range of 140–165.
155+ 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
The 20th-21st Century created specific selection pressures that rewarded Bill's profile. In a different era, the same traits might have produced different outcomes.
Key Lessons
Bill's greatest strength (Analytical thinking and Competitiveness) was also their greatest liability when taken to extremes.
The The Builder 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: Bill's output was most productive when external constraints forced focus. Without structure, the same traits that enabled greatness sometimes led to overreach.
