โIQ is the most well-supported construct in psychologyโ is a nonsense phrase
IQ is a measurement system. Itโs like saying โFahrenheit is well-supported.โ
Does he mean reliability? IQ is certainly reliableโthe same person will get very similar scores across time & different tests. But thatโs not a very flashy claim, so I assume he means something more substantial than that.
Maybe Hunter means IQ tests have a high construct validity? But this is actually quite contested and always has been; IQ is very well-correlated with performance on other standardized tests (like the SAT or GRE), which makes sense because theyโreโฆalso time-pressured standardized tests. So, performance on IQ tests can predict performance on other, similar tests. Thatโs not nothing! But itโs not very grand, either.
IQ is less well-correlated, but decently correlated, with educational achievement (grades, matriculation, etc). Also makes sense, because school is full of tests.
Beyond that, IQ tends to correlate very weakly with other forms of achievement, like income. It also has very weak (negative) correlations to things like crimeโso weak that they often can vanish entirely depending on which controlling variables are used.
In other words, IQ tests tend to predict extremely well how you do on tests; it predicts reasonably well how youโll do in school, which is a part of life thatโs full of tests. And, beyond that, it doesnโt predict all that much.
So, is that really a high-validity construct? If you purport to be measuring a general test-taking ability, then sure, IQ is highly valid. If you think IQ measures something called โintelligenceโ, which is an all-purpose trait that expresses raw human potential and is incredibly important in every area of endeavor, then, no, it doesnโt seem to be a very valid construct.
Anyway, when people use imprecise, grandiose language like this about IQ, I get the unavoidable sense that this is a big performative display. Youโre supposed to think theyโre smart, because theyโre defending Smartness, as a concept, with great vehemence. And they use this kind of allusive, vague, but strident rhetoric, suggesting a deep familiarity with numbers and scientific findings. Idk, itโs all veryโฆgrasping. Striver energy.
@ahmadalfy In the video he used Math, Programming and predefined Colors.
I worked on something similar using just Math, with coloring and logic embedded in the formulas as well, only 2D though ..
So, to answer your question, you only need basic Algebraic formulas.
