What was James Joyce’s IQ?
A prizewinning Jesuit schoolboy turned Ulysses author: the record is strong, and the 200 traces to one 1998 forum post.
No IQ score has been published for James Joyce, and the 200 that circulates traces to a 1998 mailing-list post recalling an unnamed list. The documented record is first place in English composition at Belvedere College, a University College Dublin degree in 1902 and Ulysses in 1922. A James Joyce IQ score is therefore an inference, as of November 2026.
James Joyce’s estimated IQ
- First place for English composition in each of his last two years at Belvedere College, a Jesuit school, before graduating in 1898, according to Wikipedia’s biography.
- Enrollment at University College Dublin in 1898 to study English, French and Italian, and a degree in 1902; the Poetry Foundation’s profile names Belvedere College and University College, Dublin as his schools.
- A review of Henrik Ibsen’s When We Dead Awaken printed in The Fortnightly Review in 1900, and a fan letter to Ibsen written in Norwegian, per Wikipedia.
- In 1912, “very well” on the qualification tests for a teaching diploma in English at the University of Padua, a diploma he was refused because Italy did not recognize his Irish degree (Wikipedia).
- Ulysses (Shakespeare and Company, Paris, 1922) and Finnegans Wake (Faber & Faber, 1939); the Poetry Foundation gives the same publication years.
This is an inference from schooling and literary output, not from a test. Literary originality is only loosely tied to measured IQ, no examination marks are published, and the Padua result rests on a single biography. The range is wide, and it sits above most writers on this site mainly because of the language and degree record.

What an IQ of 145–160 actually means
Set the claim aside for a moment. If someone genuinely scored in this range, here is what that would represent.
Average is 100 by construction, and about two-thirds of people fall between 85 and 115. Take the test to place your own score on this scale.
| Score range | Classification | Share of people | What it indicates |
|---|---|---|---|
| 85 – 114 | Average | ~68% | The range most people fall into. |
| 115 – 129 | Above average | ~13.6% | Roughly one person in seven. |
| 130 – 144 | Gifted | ~2% | The threshold most high-IQ societies use. |
| Above 144 | Highly gifted | ~0.1% | Figures above this range are extrapolated from the curve rather than measured. |
Percentages are approximate and describe a normal distribution. The same number means different things on tests with different standard deviations.
Thirty questions gives you a measured position on this exact scale — your score, your percentile and the ability breakdown behind it.

Who was James Joyce? He was born on February 2, 1882, in Rathgar, Dublin, and died in Zurich on January 13, 1941, according to Wikipedia. He began school in 1888 at Clongowes Wood College, a Jesuit boarding school in County Kildare, and left in 1891 when his father could no longer pay the fees. From 1893 he attended Belvedere College, another Jesuit school, without fees, and won first place for English composition in his final two years before graduating in 1898.
What did James Joyce study? He enrolled at University College Dublin in 1898 to study English, French and Italian and graduated in 1902. In 1900 The Fortnightly Review printed his review of Ibsen’s When We Dead Awaken, and he sent the playwright a fan letter in Norwegian.
He later taught English at the Berlitz school in Trieste, and in 1912 he applied for a teaching diploma at the University of Padua. Wikipedia says he did very well on the qualification tests but was refused because Italy did not recognize his degree from an Irish university. His second languages are part of the record, not a score.
Was James Joyce a genius? “Genius” is a label, not a score. The documented record is that of a Jesuit-trained scholar and a novelist whose books are Dubliners (1914), A Portrait of the Artist as a Young Man (1916), Ulysses (1922) and Finnegans Wake (1939), the four titles the Poetry Foundation lists. Ulysses was published in Paris by Shakespeare and Company, the bookshop run by Sylvia Beach, and Paris was Joyce’s main home from 1920 until 1940.

Where the 200 figure came from
Following a claim back to its first appearance is the part almost nobody does — and it is what most people are actually asking.
James Joyce IQ searches lead back to one number, 200. It appears in a November 24, 1998 post on the Extropians mailing list, where Mike Linksvayer quotes Hal Finney remembering a list of estimated IQs on which Joyce ranked first. The post names no list, test, examiner or year, so the 200 is a memory of a ranking, not a result. For how such numbers spread, see where celebrity IQ numbers come from.
What is James Joyce’s estimated IQ if no test exists? The honest answer is a range inferred from documented achievement, 145–160 here. That matches C. S. Lewis (145–160, from his Oxford record), sits above Virginia Woolf (140–155) and Ernest Hemingway (128–145), and stays far below the circulating 200. On the usual scale a 145 is about the 99.9th percentile, and a 160 about the 99.997th.
Did James Joyce have a high IQ? Nothing published shows it as a measured fact. The reputation rests on the range of what he did: a prizewinning schoolboy, a language graduate and the author of a novel that still sets the standard for modernist fiction. A large vocabulary is part of that picture; vocabulary and IQ explains what word knowledge can and cannot show.

The sources behind our estimate
The figures that circulate for James Joyce, what we were able to confirm, and where the two diverge.
A November 24, 1998 post on the Extropians mailing list, in which Mike Linksvayer quotes Hal Finney, recalls a list of historical figures’ estimated IQs: “James Joyce was at the top, with an estimated IQ of 200.”
The post is a memory of a list seen “years ago.” It names no author, test, method or year for that list. Wikipedia’s biography and the Poetry Foundation’s profile describe his schooling and books without giving any IQ.
The 200 sits 40 points above the top of the 145–160 range. On a scale with mean 100 and SD 15, a 200 is nearly seven standard deviations above the mean, beyond what any IQ test has items to measure, and its only source is a recollection.

James Joyce — frequently asked
What was James Joyce’s IQ?
No IQ test result for James Joyce has been published. The 200 that circulates comes from a November 1998 mailing-list post recalling a list of estimated IQs seen “years ago,” with no test, author or year named. This site’s estimated range, inferred from his documented record, is 145–160 on a scale with mean 100 and SD 15.
What is James Joyce’s IQ score?
James Joyce’s IQ score is not documented. The only number found is 200, from a recollection of an unnamed list, not from a test. His documented record, such as first place in English composition at Belvedere College, a University College Dublin degree in 1902 and Ulysses in 1922, supports an estimate, not a score.
What is James Joyce’s estimated IQ?
A James Joyce estimated IQ is an inference, not a measurement. This site rates it at 145–160 from his schooling, degree, language study and books, on a scale with mean 100 and SD 15. That range is a judgment about a documented record, and it is far below the circulating 200.
Did James Joyce take an IQ test?
No IQ test appears in Wikipedia’s biography of James Joyce or in the Poetry Foundation’s profile. The only formal tests documented are the 1912 qualification tests for a teaching diploma at the University of Padua, on which Wikipedia says he performed very well; they were subject exams, not an IQ test.
Where does James Joyce’s IQ of 200 come from?
The 200 appears in a November 24, 1998 Extropians mailing-list post in which Mike Linksvayer quotes Hal Finney recalling an IQ list seen years earlier. The post names no list, test or year, so the 200 cannot be traced to a measurement.
Was James Joyce a genius?
“Genius” is a label, not a score, and no test result supports or refutes it. The documented record is a Jesuit education, first place in English composition at Belvedere College, a University College Dublin degree in 1902 and four major books from 1914 to 1939, including Ulysses in 1922.
How does James Joyce’s estimated IQ compare with Virginia Woolf’s?
This site rates James Joyce at 145–160 and Virginia Woolf at 140–155, so the ranges overlap and no ranking is supported. Both are inferred from documented records, not tests, and Joyce’s language and degree record is what lifts his range slightly higher.
How does my IQ compare with James Joyce?
