TBH I feel that IQ tests should only be diagnostic and not definitive, but c'est la vie.
I am biased, because I have cognitive impairments but am nevertheless of average intelligence. A lot of people who claim to have a high IQ could not even tell you how an IQ test is administered. When I was given mine it was only ever with the understanding that it was a diagnostic cognitive assessment, not a "genius screen."
I take anyone who tells me their IQ with a grain of salt. Especially if it is ridiculously above average. There are only a few people throughout history who have had truly stunning IQs. And no-- Karen, who sits across from me and talks shit all day about her boyfriend while loudly slurping a Polar Pop, is not one of them.
The only thing that IQ represents is your ability to take an IQ test. The secret thing about IQ tests is that people like me might have a performance IQ of 80, which is Borderline. I'd never be accepted into Mensa, but I can still write a story that'll make you cry. So what the f*ck does that tell you?
There is also a whole hidden world about IQ tests that a lot of people don't know about. I wrote my final English paper on the evolution of the IQ test through history, and some of that shit is f*cking disgusting. There's a good show on TV now about this shit, it's called The Knick. The second season shows the development of the eugenics movement.
Recognize any of these names? Francis Galton. Lewis Terman. The Genetic Studies of Genius. Charles Warren. Prescott Hall. Howard Knox. The Immigration Restriction League. Ellis Island. H.H. Goddard. A proponent of eugenics, still using the same terminology Galton literally f*cking invented in 1883. You know the only reason the U.S. has the Stanford-Binet is because Goddard brought it over? He translated it because he wanted to use it to keep mentally inferior children out of the school system. Even though Alfred Binet outright stated that he wanted the test to be used diagnostically, not definitively.
The f*cking Pioneer Fund; do you know what that is? Wickliffe Draper, the guy who said that the entire purpose of the Pioneer Fund was to prove the intellectual inferiority of "negroes"? The Pioneer Fund who actively used the Nazi propaganda film Erbkrank to highlight their ideology?
Shit, son. There is so much disgusting history behind IQ. You really don't want to know.
William Shockley. That guy? Literally said that people with an IQ under 100 should be paid to undergo voluntary sterilization. That's right, that f*cker would walk right up to me and hand me a $20. So what the f*ck does that tell you?
