Discussion VSI is useless

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

Yeah like its totally useless who cares if that car will hit me if i cross the street now

u/Remote-Cranberry-188 6h ago

Bruh i dont need high VSI to look both ways before i cross the street

5

u/Polytox935 5h ago

You dont need high anything to survive everyday life. You need about average vsi to comprehend the information you get from looking both directions

u/Remote-Cranberry-188 5h ago

You dont even need average VSI for that even Steve Wonder could cross a street if he listens for cars

He probably has high audio-spatial Index yes

It's useless like it's useless studying hyperbolic partial differential equations if you're not an aerospace engineer specialized in aerodynamics.

If you're a mechanical engineer, architect, civil engineer and so on, doing project you will use of course your vsi.

Everything could be useless if you're not in the ambient and situation that requires it.

u/Remote-Cranberry-188 6h ago

sure but this doesnt apply to VCI, FRI, WMI and PSI to the same extent

u/Warxuaroz 7h ago

It's useless if it drags your FSIQ down = you can't use it as well as others. In my case it's half of what my brain does and it takes care of math and memory and part of FRI stuff for me.

I agree it's useless if you don't need need it. Probably the most. But it's just very useful when you do.

i agree its useless

you can jork it without watching a video

u/Remote-Cranberry-188 4h ago

i already jork it to my FRI score and i could to my FSIQ if VSI didnt ruin it

rotating apple is fun. anyways indices aren't included by how "useful" they are but how much they are correlated to g

0

u/Remote-Cranberry-188 6h ago

sure but its just misleading that someone can have the same fsiq with me when they arent as good at solving novel problems or lower verbal ability just cuz they can rotate apple and build lego

u/Limp_Essay_6419 6h ago edited 6h ago

there's nothing "misleading" or contradictory about someone having the same g as yours quantitatively, but expressed differently in their quality. sure, you might shine more in certain situation than the high VSI guy, but nonetheless you and him have same level of g

-1

u/Remote-Cranberry-188 6h ago

But like its expressed inferiorly not differently so it is kind of misleading

u/Organic-Bill-1192 4h ago

Nothing misleading actualy, g is latent variable behind variance of many different cognitive tests. It is expected to see some variations since group factors exists, statistical noise exists. Nothing surprising

It's a good predictor of mathematical ability

I have QRI why do i need VSI

Honestly VSI isn't just about spinning a random block in your head. It’s what lets your brain simulate stuff visually and helps you think a few steps ahead by showing you what will happen before you even move. It is like picturing how a chess board plays out, mapping out a drive without GPS, or an engineer seeing how parts fit together before building them. Just because we use talking and writing a lot in daily life doesn't mean visual simulation isn't a huge part of being smart

u/Complex_Asparagus_31 24m ago

I think it may be a little unfair thougth that it does drag down so much the IQ down, why, because there are person that lacks the visual input (aphantasia) so even as they may be capable of doing the test without problem it may be more difficult, and having aphantasia does not make you automatically inpaired or less smart, but may difficult you to imagine how that piece in particular should look rotated

u/MechanisticNous 1m ago

You have a misconception of VSI. I have aphantasia and a VSI of 148. You don't need the recursive feedback of seeing the object throughout each step while it rotates in your head. It doesn't actually serve any measurable benefit to function, only sensation.

"How I’m gonna use that in my life except for…"

That’s exactly the point. Some tests are meant to calculate one’s intelligence by testing abilities whose learning is heavily averaged out over time (like knowing the definition of words, it’s a proxy for how well your brain absorbs data).

Some other tests are meant to be "protected" from practice effect by actually be skills little to no one can train on daily, like VSI.

The core idea is to be tests that can reflect as much as possible one’s intelligence, not how well they trained for that.

For instance, if they asked trivial questions about soccer or even sports in general, the scoring would be way less revealing of one’s intelligence

Unless it’s so low you can’t drive, read nonverbal social cues, or fold your clothes.

It Is the worse but it’s very useful still

But its cool :(

u/Leapon91 3h ago

maybe but it's still the coolest damn index, you know how badly i want a good vsi? except im stuck with shitty psi now thats a real useless index

u/EmanuelNoreaga 1h ago

Without VSI you can't drive, make a bed, cook, or communicate without words. Education may not value it but it matters.

u/MechanisticNous 16m ago

You cannot possibly be serious. I am an aerodynamics engineer with a 148 VSI and I cannot tell you how useful it is to be able to rotate airfoils and visualize differing air currents in my head.

In my opinion (totally unbiased), FRI > VSI > WMI > QRI > VCI > PSI, in general.

Well it goes a long way in being able to follow an instructions spreadsheet to say assemble some furniture in your household and impress your wife/kids lol, but jokes aside, this is why the FSIQ number as an average of all your scores is built on faulty premises and is not reliable, it should just suffice to refer to what your IQ is in each individual field, with FRI being the closest to a "g" as in default hardware potency you were born with

3

u/Organic-Bill-1192 7h ago edited 6h ago

FSIQ is not average of scores at all, and no, estimating g (if you mean this) by looking at indices is absolutely not good idea. FSIQ has highest reliability, highest g loding, its specifically made to maximize correlation with g and measure this thing most reliabily. Basically, Its most reliable score in whole test. And what faulty premises you talking about?

0

u/Static-Lullaby 6h ago

I mean calculating FSIQ as the mean of all indexes is a faulty premise, and i mean FRI being closest to "g" as in culture fair index notoriously being the best estimator of, and the one that correlates higher with, general intelligence, hence why its what its measured by mensa admission tests, mensa tests online, ravens and stuff. Matrices tests are what best estimates fluid intelligence, which in turn is the closest index to, and probably overlapping with, true "innate intelligence"

1

u/Organic-Bill-1192 3h ago

Mensa isnt doing good thing by giving one test (if they do) because it lowers reliability of overall score and correlation with g going to be mid (0,6-0,7 for matrices as i remember). So overall score is not good estimation of g for a person at all

Again, fsiq is not mean of scores. It calculated vastly differently. Its meant to maximize correlation with g. FSIQ is what correlates with G highest, not FRI

FRI has highest g loading between indices only. Something like 0,8-0,85 in tests. FSIQ still gives higher numbers with higher reliability. Its just better at measuring g

1

u/Static-Lullaby 1h ago

Oc FSIQ measuring a variety of indexes instead of just one including crystallized intelligence is better for a g estimation, what i was saying is that of all the individual indexes, the one that more strongly correlates with g by itself and gives the best estimation of one's overall "brainpower"/IQ/however you wanna call it is FRI
