Michael Faraday IQ
Physicist & Chemist · 1791–1867
Quick Answer
Michael Faraday's IQ is estimated at 150 to 170. Cox's 1926 study gave him a corrected 170, though he had almost no formal schooling.
Cox's corrected estimate was 170. Faraday is the clearest case on this site of a mind that did first-rank physics with almost no mathematics.

Evidence status: Low confidence. Faraday died in 1867. 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 Michael Faraday's IQ?
Faraday never took an IQ test. Catharine Cox's 1926 historiometric study gave him a corrected estimate of 170. Adjusted for the Flynn effect that falls to about 150, so LifeScore uses a range of 150 to 170 for a man who left school at 13.
How did Faraday do physics without maths?
Faraday pictured forces as lines filling space, and he tested that picture with thousands of careful experiments. He could not write the equations. James Clerk Maxwell later turned Faraday's lines of force into mathematics and said Faraday had been thinking mathematically all along.
Where does the 170 figure come from?
The 170 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 Michael Faraday near 150.
LifeScore lists 150+, and the working range of 150 to 170 spans both figures. None of them is a test result.
How smart was Michael Faraday?
Electromagnetic induction
In 1831 he showed that a changing magnetic field makes an electric current, the basis of generators and transformers.
The first electric motor
In 1821 he made a wire rotate around a magnet, the first conversion of electrical energy into continuous motion.
Laws of electrolysis
He worked out the rules of electrolysis and coined words like electrode, anode, cathode and ion.
Field lines
His idea of fields of force filling space became the foundation of modern physics through Maxwell.
How Faraday thought
Faraday reasoned in pictures and experiments. Where others wrote equations, he imagined lines of force and then built an apparatus to test what they predicted. His laboratory notebooks record thousands of numbered experiments, each designed to rule one idea in or out.
Evidence behind the Michael Faraday 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 Faraday a corrected estimate of 170, about 150 after a Flynn-effect adjustment.
- He left school early, trained as a bookbinder and won a job with Humphry Davy by sending him bound notes of Davy's own lectures.
- He discovered electromagnetic induction in 1831, the principle behind every generator and transformer.
What the estimate cannot prove
- His lack of formal mathematics shows that one number cannot capture very uneven profiles.
- Cox's corrected figures depend on biographical detail, which was thin for his childhood.
- Cox's scale runs higher than modern deviation IQ.
Faraday vs Maxwell, Tesla, Edison
How Michael Faraday's estimate compares with related figures. Every number here is an estimate, and the basis differs from person to person.
| Figure | Estimate | Range |
|---|---|---|
| Michael Faraday | 150+ | 150–170 |
| James Clerk Maxwell | 165+ | 155–175 |
| Nikola Tesla | 160+ | 145–170 |
| Thomas Edison | 145 | 130–155 |
Take the Faraday IQ test
Michael Faraday's estimate is 150+. Our Einstein IQ test is a short visual reasoning challenge. See which side of that number you land on.
Take the Faraday IQ testMichael Faraday's IQ is represented here by a retrospective estimate of 150+, not a verified test result. Michael Faraday is best known for exceptional experimental intuition. The useful question is what the surviving evidence shows, not whether a precise modern score can be recovered.
Psychological Profile
Self-taught experimenter with extraordinary physical intuition. Modest, methodical and deeply curious.
The dominant archetype here is The Builder. This archetype shapes decision patterns: what feels natural, what creates friction, and what blind spots tend to emerge.
Estimated IQ is 150+. This is a rough estimate based on documented accomplishments and contemporary accounts, not a literal measurement.
Key Behavioral Traits
He taught himself science by reading the books he was binding as an apprentice.
He kept numbered laboratory diaries running to more than 16,000 entries.
He preferred plain language and started the Royal Institution Christmas Lectures for young people.
One thing most people do not know
Faraday turned down a knighthood and, twice, the presidency of the Royal Society.

Michael Faraday: People Also Ask
Was Michael Faraday a genius?+
Michael's record supports exceptional achievement, but "genius" is not established by an unverified IQ number. Their The Builder archetype, combined with Experimental Intuition and Self-Education, is a more useful interpretation of their output.
What personality type was Michael Faraday?+
Michael fits the The Builder archetype. Key traits include Experimental Intuition, Self-Education, and Visual Thinking. This profile helps explain both their strengths and their documented failure modes.
What can we learn from Michael Faraday?+
Michael's profile teaches that extreme strengths create extreme trade-offs. Their Experimental Intuition and Self-Education enabled success but also created recurring friction.
