I recently got an email from a college age man who was concerned that his VERBAL KNOWLEDGE INDEX (as I call it) was in the genius range (on both the children and adult version of the Wechsler) despite the rest of his cognitive profile being mediocre or low. When he asked his psychiatrist to interpret the results there was no helpful reply, so a friend of his suggested he contact me.
I’m not a psychiatrist so my opinions are for entertainment purposes only.
The first thing I did was correct all his subtest scores for norm inflation because the WISC-IV norms were 11 years old when he was tested and the WAIS-IV norms were a decade old. The sources I used were pg 240 of James Flynn’s Are We Getting SMARTER? and this table found here:

Such corrections are approximate because one can’t always assume that the rate of norm inflation can be extrapolated beyond the dates from which we have data and some subtests are so new, their rate of inflation had to be estimated using similar tests. In some cases there was norm deflation (see Coding in the table above, aka Digit Symbol).
The next thing I did was substitute the four index scores used on the WISC-IV and WAIS-IV with the five index scores used on the WISC-V. Again this gives only approximate results because the WISC-V index scores were built exclusively on WISC-V data and you’re not allowed to just substitute different versions, and in some cases I had to substitute subtests or adjust for not having the right number of subtests.
Nonetheless, the five factor model is so superior to the four-factor model, that for entertainment purposes only, I did it anyway.
The other liberty I took was calculating his overall IQ, by weighting all five indexes equally (the WISC-V gives equal weight to all core subtests, but more core subtests fall under some indexes than others).

The first thing we notice is remarkable stability as we move from the children’s scale (2013) to the adult scale (2016). In 2013 his overall IQ was slightly below the U.S. mean of 100; in 2016 he scored slightly above, and even this modest increase might be partly explained by practice effect.
In 2013 his profile was verbal > abstract > working memory > processing > spatial. In 2016, verbal > abstract > processing > spatial > working memory. In other words there is a near perfect 0.95 correlation between his cognitive profile in 2013 and 2016, despite the fact that different versions of the Wechsler (with different questions) were used on each date.
Vertical reliability vs horizontal reliability
Reliability (not to be confused with stability) is typically measured by dividing all the items on a test in half in some random way (e.g. odd vs even numbered items). If the total score on all the odd number items correlates well with one’s score on all the even numbered items, this suggests your score was reliable, because it internally self-replicates. The reliability of the Wechsler scales are so high at the full-scale level that they are said to have a standard error of only 2 points, meaning in 2/3rd of all cases, one’s score is within 2 points of one’s “true” score and in 95% of cases, one’s score is within 4 points of one’s true score.
But what is true score? True overall score is the overall score one would get on the Wechsler if we could make every subtest infinitely long, yet factor out fatigue, practice effects, and ageing.
However I propose an alterative definition of true overall score: the overall score one would get on the Wechsler if we could increase the number of subtests to infinity, yet factor out fatigue, practice effects, and ageing. But since many subtests redundantly measure the same functions, what we really want to do is increase the number of index scores to if not infinity, then the maximum number that exist within the human mind. Let’s call this horizontal true score, to distinguish it from the typical definition of true score, which we can call vertical true score.
To measure horizontal true score, imagine we were doing a poll of the average IQ in a given school. If we tested five students, and they had an average IQ of 80 with an SD of 10, then the standard error of our poll would be 10 divided by the square root of our sample size.
Now instead of trying to find the average IQ of different people in a school, we’re instead trying to find the average index score of different talents within the same mind. Once we find the standard error of the average index score, we could convert it to standard error of overall IQ (because index scores are imperfectly correlated, one’s composite score on multiples indexes tends to be more extreme than one’s average index score). Multiplying the standard error by 1.96 and then adding and subtracting it from the overall IQ gives the 95% confidence band.
Based on the amount of scatter, I calculate that all we can say with 95% certainty is that the subject’s true horizontal overall score is anywhere from IQ 73 to IQ 122 (in 2013) and anywhere from IQ 78 to IQ 133 (in 2016).
So the subject is either very smart, or very not-smart but we can’t be more precise than that without running several more tests.
Career advise
Subject will be disapointed that I didn’t devote more content to this section, but there’s only so much career advise to be gained from Wechsler test results. He is a genius at overall verbal knowledge, but only slightly above average at social knowledge (comprehension), slight below average at processing and poor at working memory and arithmetic. His social knowledge is not poor (and given the low reliability of a single subtest, should not be over-interpreted), and when combined with his genius overall verbal knowledge, he would probably have a competitive edge. I suggest he pursue whatever he field he is passionate about, as long as it’s not closely related to law, STEM, clerical or visual technical skills because these require working memory, arithmetic, processing speed and spatial ability respectively.
this distinction between class and economic status is especially…
what?
the point is there are shit/dirt poor brahmins and billionaire dahlits.
example of super high IQ – american:
bill chen.
PhD in math from UCB. really good poker player. head of stat arb for – firm SIG.
actually i wouldn’t be surprised if bill chen didn’t score very high on the GRE V or the SAT V…
BUT i wouldn’t be surpised if he socred HIGH either.
people who live in “the mind” may become very insensitive to “the world”.///
bill chen is a great example fo why australia is the UAE of the future…they get all the bill chens.
but i expect the brahimns still have better TASTE than the billionaire dahlits.
What does everyone’s political compass look like?
only someone with autism wouldn’t know this test is fake.
wtf are “developing countries plant genetic resources”?
this is what’s called a “push poll”. almost everyone will be in the third quadrant.
Economic Left/Right: -6.75
Social Libertarian/Authoritarian: -2.41
Economic Left/Right: -2.88
Social Libertarian/Authoritarian: -0.97
I am close except I seem to be less liberal in social terms.
I think it’s because despite being extremely liberal in terms of sex, religion, drugs etc. I am very nationalistic and a believer in a punitive justice system as I don’t think much of rehab chances.
Based. Am pro-choice because otherwise is infeasible, but gotta love lefties who will terminate their own kin out of convenience and then lose sleep over a cannibalistic pedophile being sentenced to death. Super high-minded people who ooze righteousness. You could say I am ‘socially liberal’ on pretty much every topic except immigration and race relations, mainly because I am reasonable, of at least average intelligence, and have access to Google.
Pretty much same here. Political compass puts me in the lib-right corner but there’s merit to some of the alt-right positions and since these are associated with Authoritarian Right, I often find myself in their camp in online scuffles.
‘You could say I am ‘socially liberal’ on pretty much every topic except immigration and race relations’ – I think you have to be at least somewhat disagreeable to come your conclusion. When high average or higher intelligence is coupled with high agreeableness you soak up liberalism across the board because that is the dominant zeitgeist. High IQ pro-social people will not be strongly anti-immigration, nor race-realist, because that is too against the grain.
Re: those political compass results (and nice dig at PP with that Oprah tab, btw), I gave the test to some normies and they almost invariably got those results. One Finance type got lib-right. Pretty individualistic and doesn’t want all his income taxed, I guess.
I remember reading a hand-me-down copy of Tell Me Why as a little kid, and from it I learned that human beings are technically animals. This fact somewhat blew my young mind, and looking back, it probably influenced my receptiveness to evolutionary psychology and hereditarianism. I’m fairly weird and sometimes try to approach political issues from the perspective of an inhuman outside observer – as if the world is a vivarium full of self-serving beasts to be analyzed. I’m not misanthropic, completely cynical, or even terribly disagreeable, but certain experiences have led me to believe that the ostensibly righteous or altruistic acts of individual men often have ulterior motivations stemming from greed and fear. This applies to me and ‘race realists’ as well, but I think we’re usually the adults in the room when it comes to considering such things as the origins and meaning of social inequality. I find it sad and and pretty funny that books like White Fragility, which of course are designed to preach to the choir instead of inspire good-faith change, assert that it is right-leaning Whites who are the ones poorly equipped to honestly talk about race.
Puppy would like this – a real social intelligence test. I applied for a job in private banking and the assessment they sent me is a series of videos of people in situations and you are asked to choose how you would respond to them.
Interesting. Send it to me.
They link they sent me is accessible to me only.
I had to take a similar social test when I tried to get a job at Walmart. I never heard from them again LOL
is this picture real?
because alex jones himself is very short.
sad.
Why are my comments on the link between autism and libertarianism modded?
plus. hunting takes way less intelligence than farming.
Yes, that explains why brain size increased rapidly once farming started. Oh wait.
The IDEA of farming is what takes intelligence. Actually doing it, not so much.

even chinese dogs are darker.
the lightest skinned dog is also the world’s most beautiful dog. and it’s not a matter of opinion.

because she didn’t moderate comments.
n/a vs pincher martin vs afrosapiens vs swanknasty vs misdreavus vs jimmy…
this is an example of the horrible side-effects of antipsychotic medications on peepee.
the very fact that peepee et al have claimed that almost all europeans aren’t lighter skinned than almost all FAR ne asians is SAD!
it means that peepee et al are obsessed with skin color.
OR that skin color disproves flushton’s CWT regarding asians.
how does it disprove?
the TWO explanations for most europeans being BIZARRELY light skinned are…
1. vitamin D, the sunshine vitamin, long residence at:
a. high latitude…LESS sun.
b. cold temperatures…and thus LESS skin exposed to the sun because clothing.
the combination selects for irish setters…pink freckled redheads…
2. sexual selection.
it’s funny that gingers are sort’ve anti-sexual…basically no one has a preference for pale freckled red heads…
but the two GREATEST geniuses of the last 500 years might both be gingers and brits.

peepee herself is a great example of ted k’s OVER-SOCIALIZATION.
she thinks farming is just putting seeds in the ground.
she’s never heard of this book:
the idea that home depot grew on a “nation of do it yourselfers” is so dumb because do it yourselfers ALWAYS overestimate their own intelligence and ALWAYS underestimate the intelligence of “laborers”.
Of all the stupid, counter-factual bullshit that institutions have forced on the world, I can’t name many worse than “p<0.05". So a one in twenty event is significant. Karl Popper must be turning in his grave.
If I were in charge, I'd put a stop to this bullshit by demanding that all published research adhere to p < 0.000001. If you can't meet that, do the study again with a larger sample size or better equipment.
UNIVERSAL PRINCIPLE: The only way to show that something is true is by doing your level best to show that it isn't
The problem is not that one in twenty is too easy a standard, the problem is they include 20 variables and then decide post-hoc which one to find a correlation in. It’s called p hacking
Both are problematic. p-hacking is just more obviously dishonest. If p-hacking didn’t exist p < 0.05 could still be too low. And remember that p < 0.05 can imply far more than a 1/20 false positive rate if there are few true positives to begin with.
well, “false positive rate” is debatable depending on how you define it; I mean the ratio of false positives to true positives
I won’t name which, but there’s a commenter here who was born on December 25th. The probability of that is 1/365, excluding leap years and that some birth dates or more common than others. So p ~= 1/365, which is less than 0.05 significance, that he would have been born on Christmas if he weren’t Jesus. Therefore, we reject the null hypothesis that he is not Jesus.
See the problem now?

1. trump is so controlled he won’t run.
2. trump will run and every other republican will drop out, so he’ll face…
a. biden (may get even more senile)
b. harris (everyone hates her)
either way he wins in 2024 because…
one of the points of the continued claims that the election was fake and gay (other than that it was) is that this promotes and allows a much more tight election in 2024…plenty for trump to win all the tight states he lost in 2020.
TRUMP IS THE NEXT GROVER CLEVELAND.

Revisiting Grady Towers’ list of IQs of Nazi leaders.
I think it’s interesting that the highest one on this list basically got away with everything, while most of the others were executed or given long prison sentences.
and the bolshies were very clever too. maybe the lesson is: never give power to intellectuals, because people are just ideas to them.
who here would be surprised if i told you Donald Trump got vaccinated in January before he left the White House?
That would be cool … My grandfather survived the Russian Front.
For the first 6 (1 executed, 1 suicide in jail and 4 acquitted or liberated later), the average IQ of the dead by 1946 is higher.
I haven’t checked your hypothesis for the all group though
normies usually have little to no cognitive flexibility in social and intellectual situations. that is something ive observed very frequently and its potent effects on their behavior is pretty transparent.

why did the pill personality pimp steve sailer and frued?
steve sailer: “I’m Catholic; I’ve always assumed I’m biologically half-Jewish (I’m adopted); and I’m an Anglophile and an admirer of WASP culture. So, I wish everyone well.”
why would someone “always assume” he was half anything? this is a dishonest autist’s way of saying, “i’m half jewish, and i know it. that’s why i’ve never posted my 23&me, why i never talk about jews, and why i’m obsessed with blacks.”
sailer talks about jews all the time

Truth
https://www.takimag.com/article/truth-or-trope/
Of the top 50 political donors to either party at the federal level in 2018, 52 percent were Jewish and 48 percent were gentile. Individuals who identify as Jewish are usually estimated to make up perhaps 2.2 percent of the population.
…
So it turns out that Rep. Omar and Gov. LePage appear to have been correct, at least about the biggest 2018 donors. But you can also see why Pelosi wanted Omar to just shut up about it: 76 percent is a lot.
I never understood why anti-semitism was such a thing. For millennia and all over the world, for some reason, people have loathed Jews. I never grasped why. Then I met one.
Just a joke. Would not open with it, but it’s humorous because it combines the absurd with the real.
against this is that so many may believe they are half jewish like so many believe they are part native american, when they aren’t, or he’s just lying to avoid the wrath of the jews and he’s tall but he does have jew hair.
it even happens to negroes. there was an npr radio show on this guy who’d always assumed he was black only to find out he was descended from the very small number of south asians in americastan 100+ years ago. some mexicans are very dark, but i assume it’s because they are part black. mexico had lots of slaves.
5% native
10% black
Just came across this. Haven’t listened to all of it, but there are timestamps in the comments section.
i saw some anti-islamification of britain activist had finally been locked up when she did her thing in northern ireland.
and i thought, “why northern ireland? i know.”/
but she was talking about islam.
mugabe’s point is if mass murder had ACTUALLY been a consequence of orange parades etc. https://en.wikipedia.org/wiki/Orange_walk in northern ireland then supressing such things wouldn’t be evil.
but they weren’t. so it is.
the empirical connection between public speech and murders would have to be beyond doubt.
but northern ireland is a VERY VERY VERY SPECIAL case, and whatever law shouldn’t apply to anti-islam speeches only to the protestant catholic thing…because that’s the only possible source of violence.
Ganzir the problem isnt the police themselves as much as the entitled folks who call the police on others. ive ran into a lot of issues with the law some warranted others not because many would just end up calling the police on me for any trivial thing they thought was a violation of their rights or whatever.
im surprised i havent ended up dead at the hands of the police though. their interactions with people are definitely shoddy but id put the blame on the pressure to do their jobs correctly by the people trying to enforce the law on others before i would say its entirely the police’s fault.
kind of insensitive but okay? i never really watch the videos here so it may not be but im garnering a guess that is to be honest.
why do you continue to lie about not being a negro peepee?
why are you always wrong? If I took a DNA test it would likely show ZERO black ancestry. Your DNA test would likely show 1% black ancestry.
and all of that 1% is in my penis.
then tell us what you are peepee and why you are TOTALLY OBSESSED with negroes and talk like a negro.
i have less than 1% African DNA and it is from East Africa. i have more ashkenazi than black jfl.
Working in a big, hierarchical organization is a good first-hand example of the positive, yet imperfect correlation between IQ and success. PP might be able to attest to this.
At each successive layer, the average IQ seems to go up a little bit (the highest person I report to probably has 15-20 IQ points on the guy who helped me with onboarding) but there’s a lot of overlap at each level.
There are definitely some guys pretty high up who I’d demolish on the WAIS, but who might always retain a slight edge on me performance-wise due to their experience, superior management skills, and higher levels of extroversion and energy, which all obviously also correlate with success.
One thing I miss about working in the office is the higher you go up the elevator, the higher the average IQ (and height). This is also true in many apartment buildings where higher apartments require more rent.
how tall are you again Pumpkin? do you think being 5 4 will limit my chances with making it in corporate even with my cognitive abilities?
In most cases it’s a huge disadvantage, but being short suits your personality and appearance so I don’t think it would limit you very much.
6′ 2″ demigod checking in. My personality was shaped when I was very small for my grade, though.
Self-professed Marxist PP gets off to smart people living better than others. At least you admit it, but Christ. Wealthy lefties are the most classist and racist of all. Rise above!
I get off on IQ tests being valid measures of intelligence, and since I define intelligence as the ability to adapt; to take whatever situation you’re in and turn it around to your advantage, high IQ people need to live better (on average) for the tests to be valid.
What I oppose though is high IQ people living better because they are selected by tests. That is extremely evil according to the correct morality.
“being short suits your personality and appearance so I don’t think it would limit you very much.”
Wtf kind of insult is that? You meanie!
Ganzir I know youre trying to be passive aggressive but ill let it slide because i know youve always had little dick energy to begin with.
Nah, I’m serious. How does being short suit anyone’s personality?
just like being fat suits jonah hills or some other legendary comedian. im not going to go into an in-depth explanation but your critical thinking skills are good enough to deduce where im headed from there.
Loaded you dont have cognitive abilities so I wouldn’t worry about it.
shut up pill whats the last thing you did that had any value on this earth. youre a waste of air and space.

Autism is not a psychological problem. It is a signals processing issue that is not about the theory of mind. Signal density is too high, it is not a personality disorder. Personality is only affected if the concentration is in social areas of the brain.

rr: people look different so ban…make everyone wear a blindfold at all times.
rr: people sound different so ban…make everyone waer earplugs at all times.
rr: people smell different…i love the smell of my black husband.
people differ in height. Ban tape measures. The weights he loves to lift should be banned as sexist since men lift more than women.
Poor RR. He doesn’t know what hes saying most times.
RR is my opinion overthinks a lot and overanalyzes etc. but he is definitely a great critical thinker Pumpkin even moreso than you.

that fake british aristocrat dutton interviewed kmac and he claimed that jews not only have high IQs but also score high on what he called “the general factor of personality”. it’s on goyim.tv.

if a girl is into you and she’s “got her own” it makes you feel like richard gere vs the dalai lama.

for example: it used to be that women stayed with abusive men because greater fear of poverty…
again:

american blacks are still DE FACTO segregated.
why?
no one asks the question?
clue: it’s THE problem, but it’s NOT just white supremacism.
GENUINE (AND FAKE) RACISM IS JUST CLASSISM 99.99% OF THE TIME.
class is not why racism happens by at least more or less the fact that class is 50% financial and 50% personality. Half are poor black or white by personality so it’s not class 99.99% unless blacks have class by personality in that margin. Only about 70% are below the 50% financially. So racism is class but to what extent. Class is 99.99% personality?
black class is black personality?
P. recall peepee’s posting a long list of sexy jewish men after mugabe pointed out that jews are ugly.

I dispatched them. I gave MeLo an identity crisis.
Can anyone see this? I tried to comment on the most recent post (from Friday), but it hasn’t shown up yet. Maybe it’s still being moderated by PP?
I paste my original comment on the post from Friday here, in case it doesn’t go through there:
Hey PP,
Can you try to explain something for me? When I was in later middle school, maybe 13, I took an IQ test (I think it was WISC-IV, but maybe WISC-III). IIRC, I scored 152 VIQ, three points from the normal cap (I did not take an extended scale test, so the ceiling would have been 155) and I capped out the Vocab subtest plus many of the other most g-loaded verbal subtests (the psychologist literally ran out of words to give me lol), but only in the high 110’s or maybe low 120’s on PIQ – let’s just say it was 120. But after that, I went on to score an 800 on the math section of the post-2016 SAT (I even got every single question right – a perfect raw score), which your conversions imply corresponds to a PIQ in the low 140s. I have also excelled (straight A’s except for one A-) in accelerated and honors math courses at an elite university renowned for its math department and known for grade deflation (it’s not Harvard, so albeit I didn’t take Math 55 or anything). Lastly, I was one question away from a perfect score on the Quantitative section of the first GRE practice test that I’ve taken (an official one from ETS), with relatively little preparation (just reading the review sections in the ETS practice book and doing a few sample exercises), and I made more than one mistake out of pure inattention or haste there, so I very easily could get a perfect QR score, and I think it’s plausible I could even get a perfect raw score with a little more focus and prep (you can get one or two questions wrong in QR and still get a 170).
If the practice test is close to a real test (which is what I’ve heard), this would imply a PIQ of 151 if I were to get a perfect score (as I think not unlikely). But that would imply that my PIQ is at least two SD’s higher than it was originally measured to be in my childhood. Maybe even more, since I seem to have capped out on the SAT and GRE, so a higher-ceiling test could show a yet-higher PIQ score. I’m now 22, so it’s been eight years since I took that IQ test: What’s going on there? What could explain this gap? Am I just a late bloomer?
I should note that various psychologists have said that I may have Asperger’s, or Non-Verbal Learning Disability, or ADHD, I have found my focus greatly improved by prescription stimulants, which I didn’t yet have when I took the IQ test. I also had particularly bad test anxiety as a little kid. And I was super-depressed in middle school (even though the school was for 99th percentile gifted kids, I still didn’t fit in at all), and I sat this IQ test specifically so that I could try and get into a high school for ultra-gifted kids, so I had a lot riding thereon, which made me even more stressed as I was sitting it. I have seen studies showing that stimulants can produce 5-7 point FSIQ gains in people with executive function deficits, like those with ADHD, and that these gains are concentrated in PIQ and less effective for VIQ (something like +9 or +7 to PIQ and only +2 or less to VIQ). Maybe that’s part of it, plus stress/depression, plus late blooming? I’m just not really sure what to think.
I’m white, mostly Northwestern European, with trace (~1%) Jewish ancestry, if that’s at all helpful. I’ve heard some hypothesize that Asians mature faster and whites slower, so Asians outperform in youth and whites in adulthood – maybe that’s part of it?
P.S.
How do you calculate FSIQ from VIQ an PIQ? I know it’s not a straight average, but I don’t know the specific method? For example, what FSIQ would someone with a VIQ of 152 and a PIQ of 151 have?
