Where 160 Falls on the IQ Scale
What Is Thomas Jefferson's IQ?
Thomas Jefferson's IQ is estimated at approximately 160, placing them in the Profound Genius range. Thomas Jefferson was a Founding Father, second vice president, and third president of the United States from 1801 to 1809. Jefferson was the primary author of the Declaration of Independence.
For context, an IQ of 160 would put Thomas Jefferson in approximately the 99.99th percentile of the global population. The average IQ is 100, and a score above 130 is generally considered "gifted," while 145+ is typically classified as genius-level.

How Does Thomas Jefferson Compare?
With an estimated IQ of 160, Thomas Jefferson falls into the Profound Genius classification. This is a rare cognitive level — only a tiny fraction of the population ever scores this high on standardized assessments.
What Does This IQ Score Mean?
Psychologists generally agree that IQ captures a meaningful slice of cognitive ability — particularly in areas like abstract reasoning, pattern recognition, and verbal comprehension — but it's far from a complete picture. Many researchers emphasize that above a threshold of around 120–130, raw intelligence increasingly gives way to creativity, grit, emotional intelligence, and circumstance as determinants of real-world success.
Thomas Jefferson's accomplishments in politicians suggest a cognitive profile that pairs well with their estimated IQ — demonstrating not just raw intellectual firepower, but the drive and focus to convert it into meaningful output.
