What is Walter O’Brien’s IQ?
The 197 comes from his own account of a school test, and the paperwork was not kept.
Walter O’Brien’s IQ is unverified: he says he scored 197 on a test given by a teacher at about age nine, and he did not keep the paperwork. No test record backs the figure, which the Irish Times printed as 196 and three other outlets printed as 197.
Walter O’Brien’s estimated IQ
- The Irish Times (October 4, 2014) describes him as the person who runs Scorpion Computer Services in Los Angeles and says his life is the subject of the CBS drama Scorpion.
- Fast Company (October 15, 2014) says the lead character and the title of Scorpion bear his real-life and hacker names, and that he is an executive producer.
- No source reproduces a test report. News.com.au (September 6, 2015) says he has not taken an official Mensa-approved test since the childhood test he describes.
This range is a placeholder, not an estimate in the usual sense. The sources document a company and a television credit, but no test, degree or ranking, so there is almost nothing to estimate from. It is wide and modest for that reason, and it is not a verdict on him. If a test report is ever produced, the page should change.

What an IQ of 115–135 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.
Find out in 30 minutes →Who Walter O’Brien is
Walter O’Brien is an Irish businessman. The Irish Times (Brian Boyd, October 4, 2014) describes him as the son of a Wexford farmer who is based in Los Angeles, where he runs Scorpion Computer Services. It says his life is the subject of Scorpion, a prime-time television drama in the United States.
Fast Company (Susan Karlin, October 15, 2014) says CBS’s promotion showcased him as the 197-IQ hacker behind the show, whose lead character and title bear his names, and that he is an executive producer. The same article reports that skepticism about claims made for him had been growing in information-technology and hacker communities, and gives his answers to its questions.
On IQ, Fast Company quotes his written reply about the missing paperwork. Techdirt (Mike Masnick, September 25, 2014) separately notes that “top 10” lists of IQs are all different and none includes anyone named Walter O’Brien. This page reports what each source says and does not weigh any other claim about him.
News.com.au (Andrew Fenton, September 6, 2015) repeats the claim of 197, notes that he did not keep the paperwork, and says he has not taken an official Mensa-approved test since. As of the sources we opened, no test report has been published.

Walter O’Brien: the documented record
The estimate above rests on this record. Every entry here is a matter of public fact, which is more than can be said for the number itself.
- ChildhoodBy his own account, a teacher gives him an IQ test at about age nine. He does not keep the paperwork.
- 2014On September 25, Techdirt questions the claim and notes that no “top 10” IQ list includes his name.
- 2014CBS’s Scorpion, inspired by his life, is promoted with the 197 figure.
- 2014On October 4, the Irish Times profile says he has an IQ of 196 and notes that IQ tests take age into account.
- 2014On October 15, Fast Company publishes his reply on the missing paperwork.
- 2015On September 6, News.com.au repeats the 197, notes that scores are scaled to age and says he has not taken an official Mensa-approved test since.
Where the 197 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.
The 197 traces to O’Brien’s own account. He told Fast Company in 2014 that a teacher gave him an IQ test when he was about nine and that, as a nine-year-old, he “didn’t know that I needed to keep the paperwork for future reference.” The figure then appeared in promotion for the CBS series Scorpion, which is inspired by his life. No test name, date or examiner is given in any of the four sources we opened. For how such figures spread, see where celebrity IQ numbers come from.
Two sources raise the age problem. The Irish Times noted that his score was measured in childhood and that IQ tests usually take age into account, so a bright ten-year-old is not necessarily as clever as a normal twenty-year-old. News.com.au (Andrew Fenton, September 6, 2015) wrote that scores are scaled with age, so a high score as a child does not show adult intelligence. A child result and an adult result are different measurements.
Our own arithmetic adds the scale. On the usual scale (mean 100, SD 15), 197 is 6.5 standard deviations above average, about 1 in 20 billion people, more than twice the number of people alive. Techdirt’s figure of 1 in 1.5 billion fits an SD of 16, an older scale. Either way no test has items hard enough to measure that high, a limit explained in the test ceiling. See the highest IQ ever recorded for what the famous high numbers rest on.
Mensa is the usual way to confirm a high score. News.com.au says O’Brien has not taken an official Mensa-approved test since. Fast Company reports that he did not answer a follow-up question about why he did not later take one. For what Mensa accepts, see the Mensa score requirements and Mensa statistics.
Compare other business names in this section. Elon Musk (140–150) and Bill Gates (150–160) have ranges built on records, and Gates’s on an SAT result. Christopher Langan’s 195 at least traces to a named test, the Mega Test. O’Brien’s 197 traces to no named test. This is a statement about documents, not about the man.
How we read a number →None of the four news sources below reproduces a test report, a test name, a date or an examiner. O’Brien’s own explanation is that the paperwork was not kept.
Says O’Brien “says he has an IQ of 196,” calls him “the man with perhaps the fourth-highest IQ ever measured,” notes that his score was measured in childhood and that IQ tests usually take age into account, and says he runs Scorpion Computer Services in Los Angeles.
Describes the “197-IQ hacker” promotion and quotes O’Brien: a teacher administered the test when he was about nine and he did not keep the paperwork. He did not respond to a follow-up question about taking a Mensa-endorsed test.
Quotes the claim of being “diagnosed as a child prodigy with an IQ of 197” and notes that the “top 10” IQ lists a quick search shows are all different and none includes his name. Its 1-in-1.5-billion figure fits an SD of 16.

The sources behind our estimate
The figures that circulate for Walter O’Brien, what we were able to confirm, and where the two diverge.
O’Brien has said he has an IQ of 197. The Irish Times (October 4, 2014) wrote that he “says he has an IQ of 196” and called him the man with “perhaps the fourth-highest IQ ever measured.” Fast Company (October 15, 2014) described him in CBS’s promotion as “the 197-IQ hacker.”
Four outlets reviewed the claim in 2014 and 2015. O’Brien told Fast Company that a teacher gave him the test when he was about nine and that he did not keep the paperwork. Techdirt wrote that the “top 10” IQ lists a quick search turns up are all different and none includes his name. The Irish Times and News.com.au both noted that child IQ scores are scaled to age.
Two figures appear in print: 196 in the Irish Times and 197 in Fast Company, Techdirt and News.com.au. Neither comes with a test name, a date or an examiner, so there is nothing to check one against.

Walter O’Brien — frequently asked
What is Walter O’Brien’s IQ?
Walter O’Brien’s IQ is unverified. He says he scored 197 on a test given by a teacher at about age nine, but he did not keep the paperwork, and no test record has been published. This site’s estimated range, 115–135, is a placeholder because the sources document no test.
Did Walter O’Brien take an IQ test?
By his own account, yes: he told Fast Company that a teacher gave him an IQ test when he was about nine. He said he did not know he needed to keep the paperwork. No test name, date or examiner has been published, so the Walter O’Brien IQ test cannot be checked.
Is Walter O’Brien’s IQ of 197 real?
It is unverified, not disproved. The figure comes from his own account, and none of the four sources we opened reproduces a test report. Techdirt noted that no “top 10” IQ list it found includes his name. A childhood score is also scaled to age.
How rare would an IQ of 197 be?
On a scale with an average of 100 and a standard deviation of 15, an IQ of 197 is 6.5 standard deviations above average, about 1 in 20 billion people. On an SD of 16, the older scale, it is about 1 in 1.5 billion. No test measures reliably that high.
Why do some sources say 196 and others 197?
The Irish Times (October 4, 2014) printed that O’Brien “says he has an IQ of 196.” Fast Company, Techdirt and News.com.au printed 197. None names a test, so there is no document to settle the difference.
Did Walter O’Brien take a Mensa test?
News.com.au (September 6, 2015) wrote that he has not taken an official Mensa-approved test since the childhood test he describes. Fast Company reported in 2014 that he did not answer a follow-up question about why he did not take a Mensa-endorsed test.
How does Walter O’Brien’s claim compare with Christopher Langan’s?
Christopher Langan’s circulating 195 traces to a named test, Ronald Hoeflin’s Mega Test, which has its own limits. Walter O’Brien’s 197 traces to a test he describes but no source names. Both numbers are far above what standard tests can measure.
