Commenter Billy was kind enough to share with us the raw scores he obtained on the WAIS-IV and I have converted these into scaled scores and composite scores. I apologize to the other people who have also asked me to do this for them, but Billy just happened to ask when I had more free time and his demographics make him a unique case study.
Billy is a young American black man born to an upper-class immigrant family. Despite spending his early childhood in sub-Saharan Africa and not learning English until coming to the U.S. at around age eight, Billy obtained one of his highest scores on the culturally loaded Vocabulary subtest.
Below are Billy’s scores. Note that the subtests are scored on a scale from 1 to 19, where 10 is the U.S. mean for one’s age and 3 is the standard deviation. This is comparable to the distribution of male U.S. height, where in the peak age group, the mean is about 10 inches (above five feet) and the standard deviation is about 3 inches.
Presumably Billy took the WAIS-IV circa 2020 (14 years after it was normed). Because older tests tend to give inflated results, in the far right column I have adjusted all of the scores for the Flynn effect. The unadjusted scores are probably too high but the adjusted scores are probably too low because the Flynn effect might not be as large as folks think and may have plateaued or even reversed since 2006 (we’ll know better when the WAIS-V comes out).
| scores before Flynn effect adjustments | adjusted for the Flynn effect | |
| Vocabulary (word knowledge) | 19 | 17.73 |
| Similarities (verbal abstraction & thought organization) | 19+ | 18.11+ |
| Comprehension (socio-understanding & common sense) | 17 | 16.49 |
| Matrices (visual pattern recognition) | 18 | 17.24 |
| Visual Puzzles (spatial reasoning) | 14 | 13.62 |
| Figure Weights (quantitative comparison) | 17 | 16.24 |
| Digit Span (rote memory & attention) | 17 | 16.62 |
| Arithmetic (mental math) | 12 | 12 |
| Coding (rapid eye-hand coordination) | 9 | 8.75 |
| Symbol Search (visual scanning) | 15 | 14.75 |
| Verbal comprehension index | 150+ | 145+ |
| Perceptual Reasoning index | 136 | 133 |
| Working Memory index | 125 | 125 |
| Processing speed index | 111 | 111 |
| Full-scale IQ | 141+ | 138+ |
Normally the WAIS-IV includes the subtests Information (general knowledge) and Block Design (spatial analysis) but for whatever reason, Billy’s examiner decided to use optional subtests (Comprehension and Figure Weights) respectively. Such substitutions are allowed as long as the examiner makes them a priori, and not to help or hurt a particular subject’s scores.
Billy wrote the following in the comment section:
Like I said, it’s unofficial, so I was tested out of convenience; not from a professional. Though my personal reason outside of knowing my IQ is knowing where I’m deficient – or my cognitive profile. Based on my Mensa scores, a wonderlic at 75th percentile while a passing RAIT score just doesn’t hint at a stable profile for me. I seem to have a hard time concentrating on tasks, so I figured it’s probably a working memory and or processing speed issue. I’ve never been tested for a mental illness.
Billy’s profile shows Verbal Comprehension > Perceptual Reasoning > Working Memory > Processing Speed.
Unfortunately the WAIS-IV lumps Visual Abstraction (Matrix Reasoning and Figure Weights) into the same category as Spatial Reasoning (Visual Puzzles) creating a meaningless hybrid known as “Perceptual Reasoning index”. However if we untangle these two abilities, we see that Billy’s Visual Abstraction is almost as high as his Verbal Comprehension (both domains are highly g loaded) and that his Spatial Reasoning is somewhat lower than his Working Memory.
He’s comfortably above average in all domains, but his weak point is Processing Speed, probably because this is the least g loaded domain. It might also imply a weakness in Executive Function, but we’d need neurological testing to infer that. His very superior score in Comprehension implies high social intelligence; on the other hand Comprehension was lower than his other Verbal Comprehension scores. Had the WAIS-IV not foolishly removed the Picture Arrangement subtest, we’d have a fuller look at his social cognition.
Billy’s relatively low scores on Processing Speed and Arithmetic probably explain why he underperformed on the Wonderlic, a speed based test with a lot of number crunching.
Overall Billy is a man of incredibly high intelligence who should succeed at almost anything he sets his mind to. The results may even understimate his IQ, especially in the verbal comprehension sphere, because of his delayed exposure to English and U.S. culture.
On the other hand, the fact that Billy’s English vocabulary is so high despite such delayed exposure to English is consistent with research showing the impotence of early childhood intervention. For a more extreme example, see The Case of Isabelle.

I hope Billy isn’t another one of these BLM idiots. We have too many here already.
No. I’m right-wing and love people like Ann Coulter. and Michelle Malkin. I’m also pretty low on tribalism. As a kid, I never liked the idea of racial grouping – never liked it when people referred to others by race, such as “that [insert race] person, over there” – and envisioned a multiracial future. I’m pretty much opposite to that now, but only as a means to resolve social issues, and recognizing some hard to reconcile aspects of man. These things need to be acknowledged and addressed with clarity and not muddled by grievance politics.
I’m right-wing and hate people like Coulter. What are the *hard to reconcile aspects of man “?
Well, many things that you would commonly hear/read in right-wing circles. And I think I hinted at that when I said I am on the opposite of beliefs including/involving multiracialism. I recognize we’re optimally suited for tribalism, for example. I see that immigration in general, irrespective of race, and perhaps even delineating intra-racially, results in viable groups acting to undermining the predominant, more so than not, as a subconscious means of self-preservation from dissipation via assimilation. Assimilation, the preferable, losing to integration, the hazardous to sovereignty. Integration as it happens now, is making unnecessary trade-offs, or acquiescing to grievance, for superficial commonality.
possibilities:
1. rr doesn’t know what “rightwing” means.
2. rr’s blog is an inside joke.
3. rr is a satanist.
Wow, very perceptive and honest of Billy. Strengthens me in my opinions!
Yikes! This site is a cesspool of right-wing lunacy. Not surprising since no emotionally balanced person would define their entire self-worth by iq. Only a bitter loser who has nothing else going for them would regularly visit this site.
Also, Billy, I hate to break it to you, but you’re an uncle Tom. You know most of this site is racist, right? Why are you sucking up and engratiating yourself to them?
Also before you think about bashing me for being low iq or whatever (since that’s all that matters to you people), my iq is in the 145-155 range.
Nowhere near half the commenters here are racist. I certainly am not alt-right & I despise racists
I don’t think you’re racist, Pumpkinperson. You’re someone who takes a realist’s approach to taboo subjects like Race and IQ. But, you can’t deny that this site and the very nature of the dicussions and articles tend to attract a disproportionate number of, say, race supremacists and alt-right scumbags. I’ve seen a sizeable amount of racist comments and a more-than sizeable amount of comments with racist undertones, especially on articles that discuss race and innate differences in ability, probably because the very nature of the articles attract racists and or implicity greenlights them to show their true colors.
Just in this comment chain, there’s a guy assuming Billy is an “idiot” BLM supporter based solely on the color of his skin. This suggests to me that racist thoughts are at the forefront of this guy’s thinking processes. No normal and emotionally balanced person would bring up race every chance they get when they encounter a black guy. FFS I don’t assume someone is KKK because they’re white. This guy quite obviously sees black people entirely in stereotypes and is a racist,
There’s another guy called RaceRealist. Again, no normal, non-racist person would have a name like that. He obviously has attached a portion of his self-worth and worldview to the notion that because black people have lower IQs on average, they are somehow “lesser”. This guy probably visits stormfront and found this site by googling “black people low iqs”.
And there’s Billy; engratiating himself, looking for validation from these scumbags. Pathetic.
The comment section on any article about black people having low iqs is 10x more of a shitshow.
Why hold people who aren’t “normal and emotionally balanced” to such high standards?
Economist has a guest article from bill gates talking about saving the world. After he made microsoft remaster age of empires, everything since then has been downhill from this guy.
If Bill wasn’t socially confused hed realise the americans living in poverty are the same as the blacks in africa living in poverty.
michael jackson used “jew” as a verb. what a redneck!
using it as a verbal is also controversial, but using it as an adjective is redneck.
Puppy once again confuses himself on what social intelligence is. Having a good comprehension score is not the same as being socially intelligent. Being able to sell something to someone is way more indicative and thats not really something measured in traditional academic IQ testing.
There’s more than one type of social intelligence. There’s the social intelligence of the political strategist who comes up with the strategy and then there’s the retail touchy-feely politician who can actually execute it.
YES!! This is something I have been wrapping my mind around in the last few years. I’ve seen people one might readily assume are on the spectrum exhibit a grasp of tactical social dynamics far in excess of the average person and yet I’ve seen people that are often the center of attention(popular likable and engaging) really be oblivious to a lot of things at play.
I am introverted and at times apathetic, but feel forced to act extroverted, proper, and empathetic. So in some instances I might exaggerate my compassion, not because I don’t want to be helpful, but because the feeling aspect seems tiresome to me. I’m ready to look for a resolution, but am aware of the importance of sensitivity. And this isn’t because I might have an autistic viewpoint, but literally because it feels tiresome to be outwardly as people expect when certain events occur.
Social intelligence is the ability to read people and apply that knowledge to get what you want, if you want it in its simplest terms. Comprehension correlated with raw social intelligence more than selling something because selling something is conflated by other phenomena involved including the halo effect, how aggressive someone is when selling, etc that are part of social intelligence but do not measure the raw cognitive aspect as well as pure comprehension would!
Why did you let loaded post rap lyrics and you wouldn’t publish any of my comments?
Because your comments are not socially acceptable in today’s society.
Something that doesn’t get talked about in these heredity debates is how much genes relating to sporting success don’t really transfer well. I have a pretty good knowledge of football and rugby and I would say having a father who was a hall of fame calibre player might only increase your chances of being a good, professional level player by about 5 or 10% if I had to guess.
I’d say base physical performance attributes might transfer over more though. Things like stamina or natural strength.
I think the chances of the son of a theoretical physicist being really smart is higher than the chances of the son of a professional football player being able to play professionally at any level.
rr has already proved that time is an illusion and a snail can slime 100 meters as fast as usain bolt. and bolt can run 100 meters as fast as a cheetah.
this because modus ponens and just so stories.
read philosophy!
space and time are the same thing. (imagine all the beautify people.)
First time you’ve ever said something smart, Pill.
Yes, 10% sounds right. Most pro athletes’ kids do well in high school sports, but they’ve regressed too far to make it in the pros.
For whatever reason, the odds of a younger brother making it after his older brother does are a little higher. Maybe 15%. It’s especially common in professional baseball.
if you think “we’ll know better when the WAIS-V comes out” then you have a low IQ.
every time a new version of the WAIS comes out, they have a sample of people take both the new version & the last version in counterbalanced order to see if they give similar results. The scores are always lower on the new version causing Flynn to infer that IQ keeps increasing by about 3 points per decade. However I believe that’s an overestimate because new versions provide more coaching, so if you take the old one after you take the new one, you have a coaching advantage in addition to a practice effect (the latter being controlled by the fact that the tests are given in counterbalanced order). Flynn also assumes that if scores increased by X from the first WAIS to the second, and by Y from the second WAIS to third, then they must have increased by X + Y from the first to the third, however that can’t be assumed.
Pumpkin, would it be okay to take the WAIS-V? I want to confirm my score with the latest data. WAIS-IV is essentially outdated now, right?
You’ll benefit from a practice effect if you take it too soon. Maybe wait for the WAIS VI.
I guess I’ll wait for WAIS-VI. There’s always the Stanford Binet. However, I’ll take that officially.
By the way, it’s interesting that my RAIT scores are pretty proportional to my WAIS, but it floors on arithmetic, being about the same as what I got on the WAIS. But the RAIT is a highly speeded test, so definitely deflates my scores, but attains some essential part of ‘g’ to be still be in line with my cognitive profile.
I wonder if Billy is part of the Igbo minority. I would like to know more about his specific background in Africa and if he is considerably smarter than most of his surrounding countrymen/women.
No, I am not Igbo, nor Nigerian. I think I am unique in terms of my nationality. Not many from my country in America. Or maybe, they’re not as prominent compared to those of west Africa.
Billy are you Ethiopian?
Just sub-Saharan African. Lol kind of reluctant to say where.
Or from zimbabwe or Mozambique or elsewhere? All hail motha africa brudda!
“every time a new version…” means nothing peepee.
the wechslers are normed on like 2,000 people.
they’re owned by pearson. https://en.wikipedia.org/wiki/Pearson_plc
they’re just a way to sell books for a $1,000 and make a living for “psychometrists”.
it’s fake and gay. everyone with a high IQ knows this.
better to spend your “hard earned” money on 25 year old highland park.
of course they’re a money grab now but that’s not how it started. Wechsler had a passion for intelligence. He discussed it obsessively. Gallup polls are based on even fewer people and can reliably predict the popular vote of presidential elections
Despite knowing a lot about important subject matter, historians generally seem to lack insight into how to deal with our problems today.
Someone like Niall Ferguson could probably give you a thorough account about any time in European history, yet afaict he endorses the Washington Consensus. And there are plenty more like him. This phenomenon is really weird.
I like Ferguson’s books but his economic ideas are terrible. Hes a pretty standard Thatcher Tory and in his history of the brit empire made out she saved the uk.
he’s not a thatcherite. those folks don’t exist anymore. he’s just a butt goy.
just listen to the way he talks. aesthetics don’t lie. he’s fake and gay.
Billy
How closely does your score align to any self-scoring IQ tests you’ve taken in the past? Either self-scoring books or online format?
I scored 140 or something close to it on Victor Serebriakoff’s self-scoring test. Other than that, my online test scores are all over the place. All I knew was that I’m between 125-145.
Correction: Not on Victor’s test, but Test Your IQ by Alfred Munzert.
Very good question, thanks
You could also try https://openpsychometrics.org/tests/FSIQ/
It’s not as comprehensive as a true FSIQ would be, since it ignores processing speed as its own facet, but I scored about 140 on version 1 and 2. Could be coincidental.
woww. Very unusual. No, I did not try the verbal section, mercy for a Russian! WM =101 ( i thought it would be zero lol), the spatial stuff =136, not sure
I see they updated the test with a new subtest for every section they had. I scored a 110 verbal, 91 spatial, and 72 WM iirc the first time I had taken it when billy recommended I do it.
Now, with three additional subtests I got a 101 verbal, 93 WM, and 84 visual.
Im sure the scores are deflated due to selective sampling on the part of the test makers, site, and people taking it.
First time I took it I was high so I was uninterested. This time I just wanted a rough estimate so I took it as fast as I could. Could’ve done better on WM and in the spatial i didnt understand how to correctly answer the second part. Verbal i worked relatively well on, expected a higher score but its whatevs.
rr doesn’t unnuhstan that one of the motivations behind IQ tests, college entrance exams, etc. is (or was) the exact opposite of justifying inequality.
it is (or was) to identify talented people from disadvantaged backgrounds.
what does rr think of the MUCH greater use of standardized in non-shithole countries? (the US and canada are shithole countries.) what does he think of the gaoko? https://en.wikipedia.org/wiki/National_College_Entrance_Examination
if you can’t measure it you can’t change it.
the point of tests is they’re objective not that they’re perfect. less testing actually results in LESS social mobility. less reliance on tests results in LESS social mobility. this has happened in blighty with the abandonment of the 11+.
https://en.wikipedia.org/wiki/Meritocracy#Early_definitions
if HYPS et al admitted students based solely on test scores this is how their student body would change:
1. the SES background would be A LOT LOWER.
2. almost no negroes or latinos.
3. only about 6% jews.
4. 80% white gentiles, 20% asians.
SO NOW RR KNOWS HE’S JUST A PUPPET OF THE JEWS. HIS MIND IS NOT HIS OWN.
I think it would be more like 40% Asian and 10% Jewish.
Off topic:
PP I recall reading that either Rushton said, or soneone said that, before Rushton encountered Jensen’s work he’d have explained racial IQ differences as a function of social learning since he was originally a social learning theorist at the start of his career (see his book Altruism, Socialization, and Society, I think it’s a good book but it’s 40 years old) but after encountering Jensen’s work he changed his views—which occurred in the period between 1980 (the publication of Altruism, Socialization, and Society) and 1984 (his first r/K paper if I recall correctly). Do you have any idea where a quote of this nature is? I’m pretty damn sure I read this and want to know if it’s my mind making it up.
I think he made comments to that effect in:
Knudson P. (1991), A Mirror to Nature: Reflections on Science, Scientists, and Society; Rushton on Race,
I don’t believe him though. He was raised in South Africa so hard to believe he didn’t believe it before. I believe jensen started out an HBD denier but Rushton seems more sneaky
How do you remember that reference offhand like that puppy? Do you have a photographic memory?
Yes
Thanks. Just ordered it.
That’s a good point about where he was raised. But Dutton (sympathetic with Rushton’s views, critical of Rushton) says that his ex-wife, I believe, said that Rushton had no racial animus. I’ll check that later. I think Hilliard says the same in Straightening the Bell Curve, I’ll find that quote later too.
peepee has the single worst memory of anyone i’ve ever encountered.
she has a photographic memory, but she never takes the cap off her camera lense.
LMAO! You’re witty, I’ll give you that.
One of the things environmentalists never talk about anymore is population reduction. In his book Freedom Jonathan Franzen actually makes the main environmentalist character a population reducer which was a position popular with the green movement until about the 90s I’d say.
I think this might be Franzen’s way of endorsing an ‘extreme’ position.
I’ve never understood why authorities or Master promotes fecundity even in shitholes. Surely the extra population is a ticking time bomb to revolution? There seems a default ‘right to have babies’ and some countries even encourage it. India could become a 2nd world country tomorrow if it had a 1 child policy.
Nothing has really changed since the 90s. I take the environment and the protection of it quite seriously so logically it means we need to reduce the worlds population fast. I don’t believe we can innovate fast enough to decrease carbon output per person or stop whats happening in the amazon or other natural habitats. I think we can forget about protecting some endangered species as long as the population in Africa is set to triple thanks to idiot retard homo superman bill gates.
I’m a [redacted by pp, april 23, 2020] and quite green when it comes to environment. I would say protecting certain natural habitats and species takes precedence over economic activity in certain cases. [redacted by pp, april 23, 2020]
I think farmers should have all their subsidies removed in the 1st world and be paid instead to promote horticulture and environmental protection if we pay them at all.
Nothing would improve living standards more in many developing countries than controlling the population. This is ESPECIALLY the case for Africa whose demographics basically dooms it to detroit levels for another 100 years.
Franzen is waaaaay over rated.
I also think that jew novelist, phillip roth is terrible as well.
Why do americans keep saying books commentating on the social landscape are masterpieces? If you write about blacks I guarantee american critics go wild. You have to write that they have a secret magical power or something or that they overcome evil gentiles.
Please don’t use Jew as an adjective. Thanks.
His jewishness is a central feature of his work puppy.
The correct term is “Jewish author”. Only rednecks say “Jew author”.
Trump is in big trouble. There is no way this gets better. Either more dead bodies or more recession. He will pick the bodies and CNN will nail him.

wow Billy im impressed….just curious where did you go to college and what did you major in??? and how did you grade-wise?? i know that you’re currently in tbe computing field…
if you took the SAT or ACT, did you receive close to the peak scores?? and how did you in terms of winning scholarships for undergrad???
I was mediocre in school and scored average on the SAT. I was never studious, and haven’t been so since elementary school. I just do well enough to pass by. However, when it comes to computer science, I am sincerely passionate.
To be honest, I never though myself anywhere near 130. I always thought I was 125-127 based on my performance. I passed Mensa, so that changed my perception a bit. And continuing to score higher has made me ambivalent about this whole IQ thing to be honest. Seems that conscientiousness matters a lot, because I lack it and have not performed anywhere near 140.
Pumpkin, how do some kids with 130 IQs who have ADHD breeze through school, and get good grades without studying at all?
I wonder what Billy’s cephalic index and head circumference values are. Kinda predicting a large long kind of head with 60 cm+ circumference.
I think I read that the correlative nature of head circumference strongly reflective of IQ is intraracial. Interracially, it correlates poorly – if I remember right. I don’t remember the exact number, but I think I do remember finding out my head circumference is average for Americans.
Average as in corresponding to population average or just not macrocephalic, and hence in the ‘normal’ range. IIRC macrocephaly for adults begins at 97th percentile onward for their given height and weight class.
https://www.researchgate.net/publication/286055189_Head_Circumference_in_Canadian_Male_Adults_Development_of_a_Normalized_Chart
Also do you have a qualitative idea of your cephalic index? Not asking for an exact number if you don’t have it recorded beforehand.
I see you got 17/19 for Digit Span. Impressive. How many digits were you able to repeat back to the administrator forwards, backwards and ascending?
That’s actually a perfect description of my head. Also an African. Lower IQ, though.
Pumpkin, would practicing online matrix reasoning tests affect wais iv matrix reasoning score?
Probably not as much as they’d affect Raven progressive Matrices. The WAIS-IV items seem better designed and less formulaic.
Like, if you practiced the online ones, and then if you took a wais IV matrix reasoning test, can you trust your matrix reasoning score? I went from 110-120 on online ones, and then on matrix reasoning I got 120 and on every other matrix test I got 120+.
I found that between wais IV matrix reasoning, the practice effects were 2.5 points, which is essentially nothing, so, wouldn’t it be fair to assume that there would also be essentially no practice effect from ravens to WAIS IV?
I also read that matrix reasoning on the wais was more purely pattern recognition while ravens had a lot of visual perception and attention to detail and other factors.
I know what the MR subtest from the WAIS III is, and, just like PP has said, they ( the items) were specially designed to look kinda new and unusual, in order to minimize an impact of your previous experience. They are also less regular in fallowing the same principle for finding a solution ( like, in Raven tests, within one set you practice one approach, the items are getting progressively harder, then you got a set 2 with another general rule -no, the MR is not like that. BTW it makes the psychometrical properties of the subtest a bit poorer,IMHO, but this is a different topic. And, yes, at least intuitively, the MR might be a bit more addressed to your visual skills than the all Raven stuff). S o the WAIS III was a real deal. Surely, they did not make the WAIS IV less tricky.
@Billy- How did you find school challenging at times if you have a 140 IQ?
I didn’t find school challenging. I found prioritizing my time for school work challenging. I felt invigorated when challenged, actually, but I could never make myself sit down and go through the tedium required to cement the specific knowledge to achieve at a high level.
Whenever I got home, I just felt empty and restless. So I played video games and looked to be stimulated by anything but school work. Possibly because I didn’t really have a clear vision for the future.
My childhood in America was the opposite of my childhood in my home country. I didn’t have the environment, anymore, to push me forward. I think I happen to be a sentimental type – I’m compelled by emotions to the point of being impulsive and whimsical at times; I grew very anxious due to the inversion of home life.
Billy, keeping in mind the fact that you are from Africa I bet that English is not the only language you speak, is it? What kind of music do you listen to, if I can ask you?
i took a deep dive into rr’s backstory.
turns out he was a bagman for the banana crime family of syosset new york.
“don’t you mean ‘bonanno’?” dumb people ax.
NO!
rr belonged to the banana crime family…
so named because composed of self-identified italians from nicaragua…and rr.
and “bagman”?
the banana crime family uses trick-or-treaters to extort candy for free in syosset.
rr was expelled from the banana crime family because hair.
@RuralRuski
I listen to metal. And American 50s-80s songs.
And English is the only language I speak, I can only understand my national language. I can’t speak it very well, now.
Watching Wolf of Wall St. definitely psychopaths wondering how intelligent?
Gentiles and Jews can be psychopaths and all else socios. That is my observation…
Might as well just say all caucasaoids since they exist as a rational entity.
Pumpkin, what’s the practice effect of the coding sub test, if you took it twice, one on one day, and the second one the next day?
Pumpkin, also, if you took three forward digit spans, and after each turn (which is once every 4 days), and your score increases each time, and with different items, would it be due to more attention or practice effects, or a mixture of both. And in the meantime, no strategies were used.
Pumpkin, im starting to think that the matrix reasoning subtest on the wais is more about attention to subtle details in patterns in addition to finding patterns, hence the perceptual reasoning. Also, I read one account which was saying that the matrix reasoning items were simpler than ravens matrices ones, except that the scoring is much harsher on wais iv than ravens matrices, hence equaling out. Also, the patterns are different, which theoretically should minimize the practice effect, since ravens and wais iv matrix reasoning are not the same tests.
It’s easier than the RAPM, that’s for sure. And I think the WAIS-IV, in general, is pretty generous with scores.
hey billy, if you don’t mind, how different did you feel the patterns on WAIS were compared to RAPM. Pumpkin and another guy said that they were certainly much different from the RAPM. Would you say there would be substantial practice effects? Also, how much easier is the wais iv matrix reasoning compared to iqtest.dk?
