What is Spencer Reid’s IQ?
The 2005 pilot gives Reid’s 187 and, in the same line, his doubt that intelligence can be accurately quantified.
Spencer Reid’s IQ is 187 in canon: he says so himself in the pilot of Criminal Minds, “Extreme Aggressor” (CBS, September 22, 2005), along with an eidetic memory and a reading speed of 20,000 words per minute. The 187 is dialogue, not a test result, and this site’s estimated IQ for the character, inferred from three doctorates and a high school finished at 12, is 170–190.
Spencer Reid’s estimated IQ
- The pilot, “Extreme Aggressor” (September 22, 2005), states the number itself: Reid says he has an IQ of 187, an eidetic memory and a reading speed of 20,000 words per minute, and that the “Dr.” before his name means PhDs, three of them. ScreenRant describes the same scene. The range is built around the stated figure rather than replacing it.
- In “Masterpiece” (season 4, episode 8, November 19, 2008), Reid tells a room of FBI recruits that he holds doctorates in chemistry, mathematics and engineering and bachelor’s degrees in psychology and sociology, that he turned 27 the month before, and that he is completing a further bachelor’s degree in philosophy. Three doctoral fields by 27 is a school record far ahead of age norms.
- Wikipedia’s character list says he graduated from Las Vegas High School at age 12, and Looper (Jacob Willeford, updated May 24, 2023) repeats the age; neither names the episode.
- His job is applied expertise. Wikipedia lists him as an FBI Supervisory Special Agent, the youngest member of the team, and its premise summary calls him an expert on geographic profiling. No source gives him an invention, a prize or a published discovery, which is why the range sits slightly below the 175–195 given to Sheldon Cooper, whose show adds a Nobel Prize storyline.
No test exists, and the only number the show gives is the one Reid states himself, in a line where he also says he does not believe intelligence can be accurately quantified. A real test such as the WAIS-IV generates scores only from 40 to 160, so 187 is a rank inside the story, not a result. The writers are also loose about his schooling: Looper reports that “Memoriam” places his three PhDs at Caltech while “Painless” has him mention MIT, which the episode’s writer told BuzzFeed was a mix-up. A line in another episode could move the range.

What an IQ of 170–190 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 Spencer Reid is
Spencer Reid is a lead character of Criminal Minds, the CBS crime drama created by Jeff Davis about FBI profilers in the Behavioral Analysis Unit (BAU). It premiered on September 22, 2005 and, per Wikipedia, originally culminated after its fifteenth season on February 19, 2020; it was revived as Criminal Minds: Evolution on Paramount+, which began with season 16 on November 24, 2022. Reid is an FBI Supervisory Special Agent and, in Wikipedia’s words, the youngest member of the team. Matthew Gray Gubler played him in seasons 1 to 15; Gubler returned as a special guest star in season 18 (2025), per Wikipedia.
Is Spencer Reid a genius on the record? The show’s own résumé says so. Wikipedia’s character list says he graduated from Las Vegas High School at age 12 and holds PhDs in mathematics, chemistry and engineering and BAs in psychology and sociology. In “Masterpiece” (season 4, episode 8, November 19, 2008; written by Edward Allen Bernero), he addresses FBI recruits, lists doctorates in chemistry, mathematics and engineering and bachelor’s degrees in psychology and sociology, says he turned 27 the month before, and says he is completing another bachelor’s degree in philosophy. The telling is not perfectly consistent: Looper (Jim Rowley, updated May 27, 2023) reports that “Memoriam” (season 4) has an article on Reid’s father’s computer saying he took three PhDs at Caltech, while “Painless” (season 7) has him mention MIT, which writer Breen Frazier told BuzzFeed was a mix-up between the two schools.
The memory and the speed are the other credentials. In the pilot Reid says he has an eidetic memory and can read 20,000 words per minute; Wikipedia’s article on the series repeats both, and Looper (Jacob Willeford, updated May 24, 2023) does too. The words he uses are “eidetic memory,” not photographic. Whether a memory like that goes with a high score is a separate question that the research on photographic memory and IQ and how memory and IQ relate examine; a recall or reading-speed feat is a skill on display, not a measured IQ.
Against the fictional roster on this site, 170–190 sits just under Sherlock Holmes (180–200) and overlaps Hannibal Lecter (175–195), and it sits above the memory-and-observation leads rated near 135–160. Reid’s range is a reading of how the writers rank the character: the strongest evidence is the number he states himself, three doctoral fields before 27 and a high school finished at 12, and the cap is that no source attaches a discovery, invention or prize to him. Matthew Gray Gubler appears here only as the actor who played Reid; the range rates the character as written.

Where the 187 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.
Spencer Reid’s IQ is a line of dialogue with a date on it. In the pilot of Criminal Minds, “Extreme Aggressor” (CBS, September 22, 2005; written by series creator Jeff Davis and directed by Richard Shepard, per Wikipedia’s season 1 list), Hotch introduces “Dr. Reid” to a witness who says he looks too young to have gone to medical school. Reid answers that the doctorates are PhDs, three of them. Asked whether he is a genius, he says he does not believe intelligence can be accurately quantified, but that he does have “an I.Q. of 187,” an eidetic memory and a reading speed of 20,000 words per minute, and then adds “Yes, I’m a genius.” That is the Spencer Reid IQ quote people search for. A transcript of the episode on Springfield! Springfield and ScreenRant’s account of the scene agree on the wording.
Who else says Spencer Reid’s IQ level is 187? Nearly every page, and all of them are repeating the pilot. Wikipedia’s character list says he is “known for having an IQ of 187,” and its article on the series adds the 20,000 words per minute. Looper’s “How Reid’s IQ Compares to Other Geniuses” (Luke O’Reilly, August 25, 2022) uses the number to put him more than 20 points above Einstein and Hawking at around 160, ScreenRant and CBR print it as a character trait, and TV Guide’s quiz (Julia Lechner, February 20, 2020) makes it a question with the answer 187 and observes that the number matches the penal-code number that defines homicide in California. None names a test, a psychologist or a method, because there is none: the number is scripted. This is the pattern traced in where celebrity IQ numbers come from in its shortest form, a stated figure quoted until it reads as measured. The pilot and “Masterpiece” give no second number and no scored test.
Spencer Reid IQ vs Sheldon Cooper IQ is the comparison people type next, and on paper it is a tie: both shows give their genius 187. Reid’s came first, in the pilot of September 22, 2005. Sheldon tells Penny “I have an IQ of 187” in The Big Bang Theory’s “The Pancake Batter Anomaly” (season 1, episode 11, March 31, 2008), a line a fan transcript at bigbangtrans.wordpress.com carries; ScreenRant notes the shared number too. This site rates Sheldon Cooper at 175–195 and Reid at 170–190: the stated number is the same, but Sheldon’s show adds a Nobel Prize storyline, while the sources give Reid degrees, memory and expertise without a discovery. Neither number is a measurement. Patrick Jane (140–160) and Mike Ross (135–155), two other television leads with a memory-and-observation gift, have no stated figure on this site, which is the main reason Reid’s range sits above theirs.
What would Spencer Reid’s IQ of 187 mean if it were a test score? On the usual scale (mean 100, standard deviation 15, per Wikipedia) it is 5.8 standard deviations above average, roughly 1 person in 300 million. Wikipedia notes that the WAIS-IV can generate a full-scale score only from 40 to 160 and that reports of scores much higher than 160 are considered dubious, which is the subject of the highest score a test can report and how rare a high IQ score is. The word Reid uses for himself in the pilot, genius, is a different matter from a cutoff; see what counts as a genius IQ level. A number for a real person has to come from a test that person sits. In the show, 187 is shorthand for genius.
How we read a number →Source of the quoted lines. Pilot: Hotch’s introduction of “Dr. Reid,” the witness’s remark that he looks too young for medical school, “They’re PhD’s. 3 of them,” “Are you a genius or something?” and Reid’s answer that he does not believe intelligence can be accurately quantified but does have an IQ of 187, an eidetic memory and a reading speed of 20,000 words per minute, then “Yes, I’m a genius.” “Masterpiece”: Reid’s recruitment talk (doctorates in chemistry, mathematics and engineering; BAs in psychology and sociology; “I’m 27”; an additional BA in philosophy). Fan-made transcripts: the lines are quoted from them.

Created by Jeff Davis; CBS, premiere September 22, 2005, originally culminated after its fifteenth season on February 19, 2020; Evolution on Paramount+ from November 24, 2022 (season 16), season 18 premiere May 8, 2025; the pilot written by Jeff Davis and directed by Richard Shepard; “Masterpiece” is season 4, episode 8, November 19, 2008, written by Edward Allen Bernero; Reid as FBI Supervisory Special Agent, the youngest member of the team, an expert on geographic profiling, “has an IQ of 187, can read a dizzying twenty thousand words per minute, and has an eidetic memory”; Gubler in seasons 1 to 15, absent from season 16 and a special guest star in season 18, episode 3 (2025).
“Dr. Spencer Reid has an eidetic memory and an impressive IQ of 187”; describes the pilot scene in which Hotch introduces him, the witness thinks he is too young for medical school and he says his title comes from three PhDs; PhDs in chemistry, mathematics and engineering cited to “Masterpiece”; notes Sheldon Cooper’s IQ is also 187; compares 187 with Einstein’s 160. No method named.
O’Reilly prints “an IQ of 187” and sets it against about 160 for Einstein and Hawking, with no method and no episode named. Rowley reports that “Memoriam” (season 4) puts three PhDs at Caltech in mathematics while “Painless” (season 7) has Reid mention MIT, and that writer Breen Frazier told BuzzFeed it was a mix-up. Willeford repeats graduation from high school at 12, an eidetic memory and 20,000 words per minute.
CBR ranks Reid fourth and writes that his eidetic memory and “IQ of 187” make him unique; no ranking method on the page. TV Guide’s quiz asks “What is Spencer Reid’s IQ?” with the answer 187 and notes the number matches California’s penal-code number for homicide; it does not say that was the writers’ intent.
Modern IQ tests transform the raw score to a normal distribution with mean 100 and standard deviation 15; reports of scores much higher than 160 are considered dubious; the WAIS-IV can generate a full-scale score in the range of 40 to 160.
Reviewed: the scripts of the pilot and “Masterpiece”; Wikipedia’s character list and series articles; ScreenRant, Looper, CBR and TV Guide. The only IQ figure is the 187 Reid states about himself in the pilot; no page names a test.
The sources behind our estimate
The figures that circulate for Spencer Reid, what we were able to confirm, and where the two diverge.
Spencer Reid’s IQ is 187. Wikipedia’s list of Criminal Minds characters says he is “known for having an IQ of 187,” and Looper (Luke O’Reilly, August 25, 2022), ScreenRant (Philip Etemesi, updated July 14, 2022), CBR (Florencia Aberastury, February 28, 2023) and a TV Guide quiz (Julia Lechner, February 20, 2020) print the same number. People also type “spencer reid iq,” “spencer reid iq level,” “spencer reid iq quote,” “spencer reid iq score,” “is spencer reid smart” and “spencer reid iq vs sheldon cooper.”
The 187 is dialogue, and every page found repeats it. In the pilot’s transcript on Springfield! Springfield, Reid gives it as his answer to a witness who asks whether he is a genius, and ScreenRant describes the same scene. Wikipedia’s sentence on the character list carries no citation; the nearest reference there supports a different sentence. Looper sets 187 against figures of about 160 for Einstein and Hawking, ScreenRant against Einstein’s 160, and neither names a test or a method. CBR ranks Reid fourth in a list of iconic TV detectives and cites his “IQ of 187” with no ranking method on the page, and the TV Guide quiz answer is simply 187. No page gives Reid a different number, and no scored test appears in the pilot or in “Masterpiece.”
Here the circulating figure and the estimate agree, because the work supplies the number and the range sits around it with 187 near the top. On the usual scale (mean 100, standard deviation 15) 187 is 5.8 standard deviations above average, roughly 1 person in 300 million; the 170 at the bottom of this page’s range is about 1 in 650,000 and the 190 at the top about 1 in a billion (our arithmetic from the normal curve). The WAIS-IV generates scores only from 40 to 160, so none of these could be returned by that test; they describe rank in the story.

Spencer Reid — frequently asked
What is Spencer Reid’s IQ?
Spencer Reid’s IQ is 187 in canon: in the pilot of Criminal Minds, “Extreme Aggressor” (CBS, September 22, 2005), he says he does have “an I.Q. of 187.” It is a line of dialogue, not a test result. This site’s estimated IQ for the character, inferred from his three doctorates and a high school finished at 12, is 170–190.
What is the Spencer Reid IQ quote, and which episode says it?
It is in the pilot, “Extreme Aggressor” (September 22, 2005). Reid says he does not believe intelligence can be accurately quantified, but that he does have an IQ of 187, an eidetic memory and a reading speed of 20,000 words per minute, then adds “Yes, I’m a genius.” The wording is taken from a transcript of the episode.
Is Spencer Reid smart? Is he a genius?
In the show, yes: he says he is a genius, graduated from Las Vegas High School at 12 per Wikipedia, and holds doctorates in chemistry, mathematics and engineering plus bachelor’s degrees in psychology and sociology (“Masterpiece,” November 19, 2008). Smart here is the writers’ label and the character’s résumé, not a measured score.
What is Spencer Reid’s IQ score in real life?
A real test could not return 187. On the usual scale (mean 100, standard deviation 15) it is 5.8 standard deviations above average, about 1 person in 300 million by our arithmetic, and above the 160 top of the WAIS-IV’s full-scale range. This site’s estimate for Reid, 170–190, is an inference from the script, not a score.
Spencer Reid IQ vs Sheldon Cooper: who is higher?
Both shows give their genius 187: Reid says it in the pilot (September 22, 2005), Sheldon in “The Pancake Batter Anomaly” (March 31, 2008). This site rates Sheldon Cooper at 175–195 and Spencer Reid at 170–190, a slight edge to Sheldon because his show adds a Nobel Prize storyline. Both are estimates, not scores.
Did Spencer Reid ever take an IQ test?
No scored test appears in the pilot or in “Masterpiece.” In the pilot Reid states his IQ of 187 when asked whether he is a genius, and in “Masterpiece” (November 19, 2008) he lists degrees rather than test results. Treat this as no test found, not as proof that none exists.
Can Spencer Reid really read 20,000 words per minute, and is his memory photographic?
In the show, yes: the pilot has Reid state a reading speed of 20,000 words per minute and an eidetic memory, and Wikipedia repeats both. It is a claim made in fiction, not a measured result, and a memory or reading-speed feat is a different thing from an IQ score.
How does my IQ compare with Spencer Reid?
You can find out in about fifteen minutes. The IQ Metrics assessment is 30 questions, scored on the same 100-mean scale used throughout this page, so your result and the estimate above are at least expressed in the same units — one measured, one inferred. Once you have a number, the leaderboard shows where it would sit, and how we score and norm it explains the benchmarking.
