Samuel Taylor Coleridge in brief
Samuel Taylor Coleridge was born in Devon in 1772, the youngest of ten children of a vicar. He read voraciously as a child and was educated at Christ's Hospital in London and Jesus College, Cambridge, which he left without a degree. With William Wordsworth he published Lyrical Ballads in 1798, launching English Romanticism. He wrote The Rime of the Ancient Mariner and Kubla Khan, became a major critic and philosopher, and struggled for decades with opium addiction. He died in 1834.
What was Samuel Taylor Coleridge's IQ?
He was never tested. A secondary tabulation of Cox's 1926 study of 301 eminent people lists a corrected estimate of 175. Because Cox's scale runs about 22 points higher than modern norms, LifeScore lists 155 with a working range of 150 to 175.
What is the Rime of the Ancient Mariner about?
An old sailor stops a wedding guest to tell how he shot an albatross, bringing a curse on his ship. His crew die, and he survives to wander and tell the tale as penance. Phrases from it, such as "water, water, every where", entered everyday English.
Was Coleridge addicted to opium?
Yes. He began taking laudanum, opium dissolved in alcohol, for pain and became dependent for most of his adult life. He lived his last 18 years in the Highgate home of a doctor, James Gillman, who tried to control his doses.
Where does the 175 figure come from?
The 175 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 Samuel Taylor Coleridge near 155.
LifeScore lists 155, and the working range of 150 to 175 spans both figures. None of them is a test result.

The evidence behind the estimate
An estimate built from the historical record, not a recovered test score.
What supports it
- A secondary tabulation of Cox (1926) lists a corrected estimate of 175.
- His notebooks and lectures show exceptional range of reading.
- His early reading as a child is documented in his letters.
What it cannot prove
- Cox rated people from biographies, not tests, and her old ratio-style scale runs higher than modern deviation IQ, by roughly 22 points in one tabulation.
- His addiction makes later output a poor guide to underlying ability.
- Literary genius is mostly verbal and creative; an IQ test samples only part of that, and style cannot be scored.
