In his 2006 book, Richard Lynn said chimpanzees “have a vocabulary of around a dozen cries to convey information,
including the presence of predators, intrusion into their territories of neighboring groups, the location of a supply of food, willingness or unwillingness to share food, and so on.”
Using my formula for equating total vocabulary to verbal IQ (Pumpkin Person 2021) a vocabulary of 12 equates to a verbal IQ of 19 (U.S. norms).
Verbal IQ = 0.002(vocabulary) + 19.35827
One problem with this estimate is that humans are socialized by other humans, and thus exposed to far more words than chimps are. A more accurate test of ape ability comes from studies of apes raised by humans. One such ape was Nim Chimpsky who was raised from infancy by humans in an attempt to debunk Noam Chomsky’s theory that only humans can use language.
Wikipedia reports:
While Nim did learn 125 signs, Terrace concluded that he had not acquired anything the researchers were prepared to designate worthy of the name “language” (as defined by Noam Chomsky) although he had learned to repeat his trainers’ signs in appropriate contexts.[2] Language is defined as a “doubly articulated” system, in which signs are formed for objects and states and then combined syntactically, in ways that determine how their meanings will be understood. For example, “man bites dog” and “dog bites man” use the same set of words but because of their ordering will be understood by speakers of English as denoting very different meanings.
One of Terrace’s colleagues, Laura-Ann Petitto, estimated that with more standard criteria, Nim’s true vocabulary count was closer to 25 than 125. However, other students who cared for Nim longer than Petitto disagreed with her and with the way that Terrace conducted his experiment. Critics[who?] assert that Terrace used his analysis to destroy the movement of ape-language research. Terrace argued that none of the chimps were using language, because they could learn signs but could not form them syntactically as language.
So raised by humans Nim had a vocabulary anywhere from 25 to 125, which in my formula equates to a verbal IQ of 19 to 20 (the same as chimps in the wild).
More impressive claims are made for Koko the gorilla which is surprising because although gorillas have bigger brains than chimps, they are less encephalized and more genetically distant from humans.
Wikipedia reports:
Her instructor and caregiver, Francine Patterson, reported that Koko had an active vocabulary of more than 1,000 signs of what Patterson calls “Gorilla Sign Language” (GSL).[4][5] This puts Koko’s vocabulary at the same level as a three-year-old human.[6] In contrast to other experiments attempting to teach sign language to non-human primates, Patterson simultaneously exposed Koko to spoken English from an early age. It was reported that Koko understood approximately 2,000 words of spoken English, in addition to the signs.[7]
2000 words equates to a verbal IQ of 23. But if humans use words in qualitatively superior ways than apes do (syntax) then vocabulary might overestimate ape verbal IQ, because even when humans and apes are matched on vocabulary, the human can put the words in much more meaningful order. On the other hand, it’s largely because apes can’t grasp syntax that their vocabularies stagnate in the first place, so perhaps this measure is reasonable.
Another excuse to play one of my favorite bands:
Pumpkin Person 
No need for this post. Just give a vocab test to mug of pee
LOL
Someone called me an orangutan once because I’m so hairy. It never occurred to me that other men weren’t
Koko’s own handlers said that it’s “specious” to compare the IQ of Koko to human infants so it follows the same is true for adults, neverminding the problems with the test Koko was tested on (the Cattell Infant Intelligence Scale).
“One such ape was Nim Chimpsky who was raised from infancy by humans in an attempt to debunk Noam Chomsky’s theory that only humans can use language.”
They don’t use language—language is a uniquely human trait and is one of the things that makes us minded.
Nevermind the fact that almost 90 percent of the signs were signed to Koko before she “signed” them.

You don’t need language to have a mind.
However, it is weird that people would try so hard to disprove Chomsky’s theory considering language is something solely humans have the capability to do. We even have certain areas in the brain dedicated to it.

Are there any studies of animal intelligence that also estimate the standard deviation? I’d be interested in seeing how smart an already clever animal is a few standard deviations from the mean.
None that I’m aware of. But assuming I’m right that Nim had a verbal IQ around 20 & Koko had a verbal IQ around 23, this tiny sample suggests the great apes have a mean verbal IQ of about 22 with an SD of about 2 (U.S. norms) or using white norms a mean of 16 and an SD of 2
https://www.easycalculation.com/statistics/standard-deviation.php
A bigger sample size is needed.
I doubt that the concept of IQ, relative to a scale normalized on humans, is even remotely meaningful. An IQ of 22 is like one-in-ten-million lowness and I’m pretty sure that more than 1 in 10,000,000 humans are Terri Schiavo levels of brain dead, i.e., their “ratio” verbal IQ is 0.
Lowest one in 10 million of the BIOLOGICALLY NORMAL population. Terri Schiavo would not be included in the WAIS norming sample because of her medical condition; neither would many of my regular commenters.
They’re not. You can’t give animals IQ tests and expect accurate results.
Restricting IQ to the biologically normal population makes it meaningless. Then you can’t assign IQs to people with ultra-high IQs either because they probably aren’t “biologically normal” either.
They’re not restricting IQ to normies, jut restricting the norming sample to them. If you include abnormal people you can’t expect a normal curve.
Define “biologically normal.” Do you mean limiting the norming sample to people whose IQ is affected only by those factors which underlie the normal distribution of intelligence in the first place? If so, how would you figure out whether or not a given person belongs to that group?
Are autistic people be excluded from norming regardless of how functioning they are?
“If you include abnormal people you can’t expect a normal curve.”
Yeah Ganzir, get out of here with your silly ideas of norming tests on humans without exclusions and start doing sensible stuff like estimating normal curves by lumping chimpanzees and gorillas together 🙂
(No offense to Pumpkin or Enrico Fermi intended)
I think diagnosed autistics would be excluded. People with any physical condition or illness that might depress performance are excluded such as stroke, epilepsy, brain tumor, TBI, brain surgery, encephalitis, meningitis, ADHD, psychotic disorder, parkinson’s, dementia, learning disorder, mood disorder, language disorder, substance abuse or dependence
“lumping chimpanzees and gorillas together”
You just described this comment section
Is the main point of excluding those people from the norming to make IQ tests better at identifying normal and abnormal scores?
It’s a bit of a pity to exclude all those ADHD cases since there’s so many of them and not evenly distributed by demographic group, which could change racial differences etc. I think they should at least include the ones who are controlling their symptoms with meds.
I think the point is that IQ tests are used to diagnose disabilities so the norming sample is supposed to be a control group of non-disabled people. The other point might be that mentally ill people don’t show their full potential on IQ tests. I don’t think these exclusion criteria make much difference, except at the lower extreme.
Surprising these experiments weren’t continued, afaik. I wonder what a large community of verbal gorillas would talk about? Probably gossip like us LOL. The smartest ones could probably learn to read logograms.
On wikipedia it looks like lots of people were skeptical about Koko’s abilities, but they seem pretty reasonable to me. Many people seem to think animals are basically braindead LOL.
“I wonder what a large community of verbal gorillas would talk about?”
I don’t know but I would expect them to randomly put LOL after their sentences for no apparent reason
[redacted by pp, 2021-05-13] gorillas and monkeys aren’t that dumb. Even dogs aren’t that dumb. You can see it in their eyes.
If you believe in large racial differences in IQ, it logically follows that there should be HUGE species differences. Humans differ far more from apes genetically & neurologically than races differ.
Puppy it actually scares me that you lack the basic sentience of living creatures to know when something is conscious and thinking and when it isn’t. You don’t need an IQ test to tell you that.
An IQ of 15 doesn’t mean you’re not thinking, it just means you’re thinking like a toddler.
The second dose of Moderna WRECKED me. Woke up at 1 AM shaking like a jackhammer with the worst headache I’ve ever had. Had to sleep under 5 layers just to stay warm.
Aspirin has done the trick so far.
Yeah my dad got vaxxed and needed an aspirin as well. The fact that it wrecks you probably means youre lucky to have gotten the vaccine and not the whole shebang. Otherwise you could well of needed hospitalisation.
Philo,
On average younger people react worse to covid vaccines but better to actual covid. So your reaction to covid vaccine shouldn’t be positively correlated to what it would have been with the real infection.
My cleaning lady had a very bad reaction to covid Pfizer but was happy because she said she probably would have died from the illness if she hadn’t been vaccinated. She asked my opinion. And I said it was a comforting thought and she was blessed to be here in France (she is from Madeira, Portugal) and be well taken care of. She couldn’t agree more 😊
You have a cleaning lady? What are you some sort of aristocrat?
my aunt has cleaning ladies. she’s not an aristocrat. they don’t live in her basement. they clean lots of people’s houses. they’re mexicans.

if you don’t have a cleaning lady by the time you’re 30 you can consider yourself a loser
I’m pretty sure I came down with covid last summer, and my reaction to whatever it was was similar but not quite as intense.
I went to a fourth of july party and suddenly felt super ill 2 weeks later. Never got confirmation, though.
“On average younger people react worse to covid vaccines but better to actual covid.”
Gonna need a source for that.
But according to psychologist J. Paul Scott, the average canine can understand approximately 200 spoken human words. Some trainers even claim they’ve taught dogs up to nearly 350 words.
That means the average dog has an IQ of 20.
verbal IQ’
Dogs evolved to live among humans so their verbal & social IQs are probably way higher than their IQs
Wonder what dick cheneys more worried about right now – israel under attack or his daughters political career?
It’s been hard for me because I don’t know whether to root for the war-mongering Israel supporter or the Racist party that committed treason.
Trump is hilarious. He likes trolling the republican party as much as the dem party.
It’s weird how he’s just completely irrelevant now.
It’s nice having a boring president.
So Prescott Bush got an in with the ruling american elite in the 50s/60s as their private banker, he introduces his son George HW as a swell guy and they make him secret police director and then he begets George the Lesser who basically was Israel’s puppet for 8 years. How does this happen?
You don’t have the social IQ to understand how it happens so don’t even ask
See, this is what I like about communism, it wants to bypass all the political infighting and just shoot everyone who disagrees with it.
Of course in practice it has always devolved into more political drama
ralph axed melo: “candace owens or tomi lahren?”
melo: “is anyone attracted to black women?”
Toni>Candace
But Candace ain’t that bad.
I’ve noticed at the high end there really isn’t much a difference between between races as far as attractiveness goes.
Hot bitches are just hot bitches. They’re all pink on the inside anyways.
i meant “milo” not “melo”.
this personality is so boring.
better question is how accurately can the most accurate judge IQ given only a head shot? this means every picture has no other clues than the face. if clothes show they’re all the same. no makeup.
example:
smart
dumb
yet same guy.
smart
dumb
“i meant “milo” not “melo”.”
Learn to speak English.
“this personality is so boring.”
You’re like an NPC that just says the same thing over and over once you press “a” enough.
You got a terrible since of aesthetics. Tupac is easily the most intelligent person there. That’s why he was the most successful. Put them all in an environment with nothing, Tupac will always come out on top every single time.
Isaac Newton didn’t even know how to drive a car. He was a virgin, and he believed in God.
All signs of severe mental retardation.
Thought the third guy down was Francis Crick for a second. He might have the most obviously ‘smart’ face I’ve seen.

jumping from an IQ in the late teens to the early twenties is incredible for a primate of non-human origin.
im guessing the variation between most non-intelligent primates in IQ is very low so its remarkable that something can bring about that much of a leap in them!
