Francis Bacon IQ
Philosopher & Statesman · 1561–1626
Quick Answer
Francis Bacon's IQ is estimated at 160 to 180. Cox's 1926 study gave him a corrected 180; no test exists.
Cox's corrected estimate for Bacon was 180. He entered Cambridge at 12 and set out a method for science; the number is still an old-scale estimate.

Evidence status: Low confidence. Bacon died in 1626. No test exists; the figure below is from a 1926 study of biographies. Historical achievement cannot be converted into a precise modern test result. This page separates documented evidence from interpretation.
What was Francis Bacon's IQ?
Bacon never took an IQ test. Catharine Cox's 1926 study gave him a corrected estimate of 180, based partly on his entry to Cambridge at 12. Adjusted for the Flynn effect that is about 160, so LifeScore uses a range of 160 to 180.
Did Francis Bacon write Shakespeare?
Almost certainly not. The Baconian theory began in the 19th century and rests on hidden codes and assumptions about education. Scholars point to contemporary evidence naming Shakespeare, his fellow actors who published his plays, and clear differences between Bacon's prose and Shakespeare's verse.
Where does the 180 figure come from?
The 180 is Catharine Cox's corrected estimate from her 1926 study of 301 eminent people born between 1450 and 1850. She rated each person from biographical records of what they could do as a child and young adult, then corrected for gaps in the record.
Cox's numbers sit on an old ratio-IQ scale. One secondary tabulation subtracts about 22 points for the Flynn effect, which puts Francis Bacon near 160.
LifeScore lists 160+, and the working range of 160 to 180 spans both figures. None of them is a test result.
How smart was Francis Bacon?
Cambridge at 12
He entered Trinity College, Cambridge, at 12 and soon criticised how it taught.
Novum Organum
His 1620 book argued knowledge should be built from observation and experiment, not ancient authority.
The Essays
His short, aphoristic essays, first published in 1597, are still quoted.
Lord Chancellor
He rose to the highest legal office in England in 1618.
How Bacon thought
Bacon thought about thinking. He listed the "idols" that mislead the mind, from wishful thinking to loose words, and proposed a slow, organised method to get past them. It was a plan for science more than science itself.
Evidence behind the Francis Bacon IQ estimate
The estimate is a structured interpretation of the record, not a recovered test score. These are the strongest signals and the reasons for caution.
Evidence considered
- Cox's 1926 study gave Bacon a corrected estimate of 180, about 160 after a Flynn-effect adjustment.
- He entered Trinity College, Cambridge, at 12.
- His Novum Organum (1620) argued for building knowledge from careful observation and experiment.
What the estimate cannot prove
- His own scientific experiments were few, so the estimate rests on method and writing.
- His career in law and politics ended in disgrace, a reminder that judgement and ability differ.
- Cox's scale runs higher than modern deviation IQ.

Take the Bacon IQ testFrancis Bacon's IQ is represented here by a retrospective estimate of 160+, not a verified test result. Francis Bacon is best known for exceptional systematic thinking. The useful question is what the surviving evidence shows, not whether a precise modern score can be recovered.
Psychological Profile
Ambitious reformer of knowledge. Better at designing a method than using it.
The dominant archetype here is The Scholar. This archetype shapes decision patterns: what feels natural, what creates friction, and what blind spots tend to emerge.
Estimated IQ is 160+. This is a rough estimate based on documented accomplishments and contemporary accounts, not a literal measurement.
Key Behavioral Traits

The Royal Society saw him as its intellectual founder.
