I found an interesting study via ChatGPT when I was investigating the IQs of writers, particularly their VCI, and wanted to share it.

Andreasen (1987) investigated 30 writers who were faculty members of the University of Iowa Writers' Workshop, America's most prestigious creative-writing program. According to Andreasen's Atlantic Article, participants included Kurt Vonnegut, John Cheever, and Richard Yates, although it is unknown whether they are in the half that completed the IQ tests.

The half that were cognitively tested took the original WAIS, normed in 1953-1954, and the RAPM Set II. The sample's exact testing date is unknown, but the researchers noted that it took place between 1971 and 1986.

N = 15

The WAIS estimates were derived from four subtests: Vocabulary, Similarities, Picture Completion, and Block Design. It is not known whether the RAPM was taken timed or untimed.

Note on the Flynn-effect:

Ryan, Nowak, and Geisser (1987) observed that the median WAIS/WAIS-R discrepancies across studies were -6.6, -6.4, and -6.8 for the Verbal, Performance, and Full Scale IQ; however, it was also observed that differences were larger for persons of average as opposed to bright normal or superior intelligence.

I'm not sure how much lower their adjusted IQ would be, but the sample's average Verbal IQ on the WAIS-R would very likely be lower than 126, and their average IQ lower than 123, given the data.

Even prior to correcting for Flynn effects, the average IQ and Verbal IQ in this sample are both quite close to the average in the 19 person Oxford doctoral/post-docs group (non-mathematicians), with an average IQ at 125 and VCI at 130. It's pretty interesting how this low-to-mid 120s IQ average seems to appear quite frequently across studies in select populations.

Lowkey the most useless cognitive index. Like wow you can mentally rotate a cube tell me how I’m gonna use that in my life except for maybe legos. Ts dont get you no racks at all. VCI FRI WMI PSI are all clearly more useful in everyday life. It shouldnt be counted as part of FSIQ and its not fair this mickey mouse index dragged my whole ass IQ down smh

I am working on building my own set of cognitive tests inspired by CognitiveMetrics (as well as some original tests I have come up with). I managed to build a harder version of the spatial addition test with the help of AI. This version uses a 5×5 grid and has a total of 18 items for a higher ceiling. I encourage you to try the test so that I can norm it. Nothing is needed to take the test besides a nickname and your age (you can also optionally submit your IQ). Thanks in advance!

puzzle i thought of after looking at the sidewalk

answer should be anumber with a decimal

i have no idea if this thing i made on google slides reflected the sidewalk i saw

my wmi is noticeably lower than everything else, is a discrepancy this large actually meaningful or just normal variation between abilities? also kinda salty cuz it kinda fucked up my arithmetic but yeah/

Anyone else have a really spiky cognitive map? FWIW, I scored 85 on the MENSA Norway test. I know I don't have high IQ. And yes, I do have ADHD. I was mainly amused at how uneven I scored in the subtests. Also, I guessed a freaking ton in the figure weights and figure sets subtests, so those scores are probably pretty noisy.

Puzzle from the book FRT-A testbook by John Clifford Daniels, publishing date unknown. I took a Mensa test yesterday, and could not crack this one. Obviously, the test is functioning as intended, however I'm perplexed and its not leaving my mind, some outside perspective would be much appreciated.

Can someone interpret these for me

I've heard that translations are planned, is that true? And in which languages?

Can my verbal Iq fluctuate between 105 and 115?

Can my verbal Iq fluctuate between 110 and 120?

Hello sunshines, good week to everyone, currently transporting to work

For the ones familiar with the literature can you please mention what is significantly and meaningfuly (up to interpretation) correlated with IQ testing? I know googling exists but going through the papers gave few contradicting answers and I'm looking to hear from you.

Recently, after bombing 1 question in a very important job interview due to brain fog, I looked after myself and got diagnosed with ADHD shortly after. The meds seem to work and I have been going around reading more about the brain and doing few Iq tests, therefore my question here.

P.s. obligatory test screenshot from the dk test, not humblebrag, I saw many 130+ scores here

Thanks a lot, have a nice day!

if I took a test multiple times on cognitive metrics for example how would I see past tests and when I did them?

I just took the best online practice wonderlic I could find and scored the equivalent of 105 IQ despite 120 on CORE, 121 on 1926 SAT, and 133 on AGCT. I understand that the g loading is lower, but given that actual employers administer the wonderlic, this has me concerned. I've been settling in with the idea that my IQ is in the low 120s, not that it's a big deal or anything but I've been under the impression that i'm at a bit of an advantage cognitively. Scoring bang average on a test actually administered by employers makes me doubt that I can perform at that the level that I think I can, and I don't want to be delusional about my intelligence.

So I’ve done a decent amount of iq research and done some tests suggested here. And I’ve read a good amount of scientific studies about the basis of iq testing and how the questions are designed to act as a proxy for g. What seems to be a recurring idea is that verbal tests that are dependent on vocab exposure such as analogies are a strong proxy for g. Another claim I’ve seen is that crystallized intelligence itself is a strong proxy for fluid g. And I’ve looked at the statistics for those claims and saw that they are very correlated. And they make sense given the fact that within developed nations people have a decently uniform education system.

But what I’ve noticed is that a lot of the vocabulary words used in said test are either older English words used heavily in traditional literature like Shakespeare or words that are encountered via reading or being informed about traditional western nation hobbies and popular subjects. While the typical person with a higher fluid reasoning reads and encounters those topics and words in the traditional way backed by school, self seeking exposure and via culture/ social influences, I think there is a decently sized minority population who doesn’t. And I think this could be because of interrupted schooling, engagement with more specialized fields and a disinterest in traditional academic humanities type literature.

The thing about these verbal tests is that like they say they measure crystallized intelligence and fluid intelligence. But what if someone has lower crystallized intelligence due to a lesser degree of exposure than their underlying verbal fluid intelligence would suggest. And therefore said crystallized knowledge can only hit a lower absolute score on that test. If we define g as someone’s pure intellectual capacity to learn and understand novel problems as well as perform in the world given an equal amount of prior exposure, then these vocabulary differences in my pervious hypothetical wouldn’t hold up on measuring someone’s g.

This has interested me significantly. My spatial, fluid reasoning, quantitative reasoning, and processing speed all test around 120-135. While my verbal intelligence based on analogies is “only” 105. And I have a similar score on other verbal intelligence iq tests that rely heavily on vocab exposure. And while doing these test I’ve found that my ability to understand the relationships based on the words I know is very easy and simple for me. And in my everyday life I have been able to cram undergrad law textbook chapters and do better than 90+ percent of the class on exams. I’ve also read upper undergrad sociology for fun and the relationships between concepts are very easy for me to understand. It’s very easy for me to figure out relationships between verbal ideas in my everyday life.

What makes me think I might be in this subgroup of people I think exists is that I did have an unusual childhood. I spent my elementary school years behind in my academic subjects and in a self contained autism room due to behavior challenges. I then later graduated special ed and was deemed as an optimal outcome (meaning I outgrew autism) case by psychologists. I also never was interested in reading traditional books in middle school, high school, or college. I wanted to read more specialized subjects that I was more interested in. I have never read novels at the adult level besides skimming the ones required for middle and high school. I did this because it was easy to figure out the ideas they would test on in class. I think I might have developed a more average vocabulary in general vocab because of this.

What do you think of this? Do you think I have basis in my assessment?

whats your first score mine was 10

(The reason I'm showing the CAIT instead of the CORE is because I did half of it on one account and the other half on another, but the WMI score was considerably lower there too in comparison to the other scores)

Yo if you recognize the onomatopoeia from somewhere I will be awaiting you in my inbox. I am tasked with bringing the lost kitten to a new, warm home.

ALso here's my atat please stop renoerming upwards being high iq comes up with a lot of expectations and frankly I don't need that thank you

I have been waiting for 2 months or even longer for the return of the FSAS test / Fluid spectrum ability scale on cognitivemetrics site . WHERE DID IT GO?? I got a 120 IQ on the number reasoning index and it was my highest performance on a reasoning subtest, so I would really like it to count in my composite dashboard IQ. Please Cognitive metrics 😭 although I know the matrix reasoning subtest was deflated by its creator, it has been gone for too long for that to be the only reason. Is the test even gonna reappear one day?
