what is your IQ?

[EnneadNokonx]

I scored a 152 when I was eight, and then scored a 162 when I was eighteen. I'm not a very fast learner, I'm good at remembering facts and information that I find interesting in some way, otherwise, forget about it.

(Comments will can be made about this, but there will be no reply from me.)

Well, if you think I or someone else is lying, please say so and don't beat around the bush about it. And no, someone who has an IQ of 145 at age 10 is not likely to turn into a "95 IQ mediocretin" as an adult, barring some sort of brain damage or mental disorder. I have no idea where you got that bit of information, but I'm guessing you made it up to support your argument. Sometimes your hubris is astonishing.

I am not kidding you. In a child, IQ is proportional to the quotient of mental age over chronological age. However, children reach mental maturity in wildly different paces, which means that as you reach adulthood, on average, the spread in IQ will decrease. It's like height, just because you're the tallest kid in class when you're 10, doesn't mean you're going to be taller than normal when you're 20.

also Dr. M.D. your statistical analysis is incorrect, the sample you took is neither independent, nor double blind. further more their may or may not be a correlation between intelligence and anime, or fiction. furthermore adjusting the sample still does not allow it to fit within a bell shaped curve, or box and whiskers.

What I did is standard normalization (I'm a physicist, I have no obligations to uphold sane mathematics). It's not statistically flawless (the sample size is terrible), but it is meaningful. IQ, per definition, has the expected value μ=100. Furthermore, it's blatantly obvious that these internet tests introduce a residual ε on the sample, so what we get is not <μ>, but <μ+ε> (don't confuse ε with a residual -- residual theory adds nothing in this case), which due to linear superposition is equal to <μ>+<ε>. So, obviously <ε>=<μ+ε>-<μ>. I'm not really saying anything about what this ε is. It may be due to the high concentration of people with high functioning autism on the internet, and/or a feel good internet IQ tests, and/or people lying about their IQ.

But there are several problems with this. The biggest problem is not the sample size, but the differences in measurement techniques. IQ tests vary in variance from 15 to 25. Which means that 130 IQ in a 15 variance test is equivalent to a 150 IQ in a 25 variance test.

[demonplight]

the greater n the less variance. you may just need a bigger sample size of the members.

Variance is also a function of measurement method. Since you're measuring the IQ of different people, you are always going to get a certain variance even with very large sample sizes.

[Amray]

You guys think you have problems? I can't even spell P.E.

[Fiery]

I haven't taken an IQ test since I was 8. I honestly can't be bothered taking another one. In reality, I don't think it's going to change my outlook on anything, including what I think of myself.

Plus, I don't think my internet cred is suffering. If it were, I'd totally put down 160.

Oh wait, I'm not Matt.

[KiriChan]

Hm, I think when I took an internet test it said that I had the IQ of 139... or was it 129? I can't remember. It was one of the two.
I never really thought your IQ was really that important though, because you could have a really low IQ and work really hard, or you could have a high IQ and be really lazy. With my laziness, I might as well have an IQ of 1 ;]

The rational is, you may just being doing the statics of the more intellectual members of the forum. if say 100 more people where to post their iq then the weight of the current scores may be offset by the mu of the sample pop n.

That is true, I would buy a 5 or 10 point offset, but I sincerely doubt that as an explanation for a 30 point offset.

[Momokachan]

At the age of eight, I took the set of tests to classify a "high-ability learner" as prescribed by my school district.

My comprehensive score was 167. However, it all depends on what the particular thing I'm doing is. As a synaesthete, I scored extraordinarily high on audial recognition. On the other hand, I scored abysmally low on mathematics and numerical sequencing.

IQ numbers are completely useless except in the context of the tests that produce them. If someone is intelligent, it will show, one way or the other.

Are you also keeping in mind the age of those posting their IQ? Shocking as it is, there's a fair amount of young'uns here.

[demonplight]

Being that an IQ test measure the ability to process data, I do not know at what point age becomes an issue. You would think that a child who plays alot of video games would have an IQ but... but be less wise. I am not sure that I am describing that appropriately. But one would imagine that would be the case. seeing that they have conditioned themselves to solve problems, and find patterns. Additionally alot of the people who delve into anime also have experience working with computers, and computer games... being that anime is a geeky thing. on the other hand, one must also take into account that people with an eye and ear for the arts also have slightly higher IQ's than the adverage person. what we may or may not have here is a case where people who have an interest in extracurriculars that promote higher IQ's share a commonality, namely anime. Thus they independently gather here, anime forum, which again is of technological interest. It may just be that the population of this forum maintains a higher IQ the the average topics, and the people who responded may have a higher IQ than the rest of the forum.

I see your point and I can agree to a very limited extent. I can see someone with an IQ of say, 110 at age 8 falling back to average or maybe slightly below in adulthood. However, while I believe the relationship between mental age and chronological age was important in the very first IQ tests, I don't believe that modern tests are scored that way. I do know that the tests I took at age 8 and age 11 were no different than the IQ tests given to adults.

In addition, I've personally never known or read of any case where someone with a well above average IQ (120+) slipped down even into the "average" category in adulthood. The decline in IQ is very gradual over adulthood...I can't imagine any situation (other than some sort of mental disorder) where someone with an IQ of 145 would have an drop in IQ to even 120, much less a below-average 95.

When I was in Elementary school, it was already well established by 2nd grade who the smart kids were and who the dumb ones were. And when I graduated over a decade later, all of those same kids were still the smartest kids in school. I strongly believe that intelligence and height are very different things and can not really be compared. If you have some evidence to the contrary, I would like to hear it...

[Lune Cy]

i'm potty trained, what IQ you need to achieve that?,xD.
anyhow, my IQ floats around 138.
somehow my IQ doesn't reflect on my personality,xD.

I do know that the tests I took at age 8 and age 11 were no different than the IQ tests given to adults.

Your IQ score is normalized against your age group (if you were to give 10 year old adult-normalized IQ tests, everyone would do miserably). So, even if the test may look identical, the resulting IQ differs. And, since you mentally mature at different rates, your IQ will probably change with age. [Reference]

I can't find any studies to support age-independent IQ. Also, 95 IQ is average. The average IQ is +-one standard deviation of 100, which depending on the variance of the testing method may be 75-125 or 85-115.

Personal anecdotes are not evidence.

[aishiteru333]

I've scored 118 and I'm almost 18, I'm an average American.... T_T

[Midnight Rambler]

I essentially agree with everything you posted now that you've dropped the whole mental to chronological age thing, Eris, but you still haven't shown me how a 10 year old with an IQ of 145 could drop to a 95 in adulthood. IQ decline during adulthood is nowhere near that profound and has to do with the brain's decreased ability to learn. A child who is brilliant (at least according to IQ tests) at 10 will still be brilliant at 30, just not to quite the same extent.

While I understand the fact that test scores are compared against those of the same age, that doesn't mean that people who have trouble with logical reasoning and problem solving are going to suddenly "get it" in adolesence and become a genius any more than someone who handles such tasks with ease is suddenly going to lose their ability and become a moron. It seems theoretically possible by the way the test scores are calculated but is about as likely to happen as flipping a coin and getting heads 20 times in a row...It just doesn't happen in the "real world".

Furthermore, the assertion that such a thing is even possible flies in the face of common sense, which was the point of my anecdote. I'm still waiting to see evidence that a gifted, near-genius child can have a dramatic IQ drop in adulthood barring a mental disorder or brain damage.

Edit: I don't want to spam this thread with too many posts so I'll just add this here. I did a little research and I believe that the IQ tests you are referring to are called "Ratio" IQ tests whereas modern tests are considered "Deviance" IQ tests where the age of the person being tested is irrelevant...

[Khanxay]

Woohoo. Turns out I'm stupid. 87 on that IQTest dot com site.

[Legend Saber]

I just took an Internet IQ test out of boredom and got 138.

Yay! Random, meaningless numbers ftw!

I'll probably have forgotten that by tomorrow.

[suzumisaya]

Well, I know I'm stupid, I don't need a test to tell me that, although I once made a test and it proved that I'm wright I'm noy a very smart person...

[Dxon]

Last time I was checked. (Was when I was 8 or so) I had a IQ of 144..

Is that high?

[serasvct]

Online tests are completely bogus and should be disregarded. Unless you have taken a test administered by a qualified examiner, you shouldn't take the number seriously.

Besides, traditional IQ tests have been widely discredited is the psychological community as not being a true measure of intelligence. They are culturally biased, and are also biased against people who are not traditional thinkers. I'm amazed that they're still used to judge entrance into "gifted student" programs at schools.

The last time I took one was part of an experiment at University. We took one, and then re-took it the next month. We were asked to deliberately "cheat" in any way we wished: studying, brushing up on rusty math or vocab skills..... and all of us managed to increase our scores. It pushed many of us into the Genius category. What a bogus measurement of intelligence!

I took a Mensa entry IQ test once, and it was all pattern recognition, no potential for traditional cramming or cultural bias. It looked a lot like danish Mensa's online test. (For reference, I did pass, but I didn't actually join Mensa, I just wanted to see if I'd pass.)

[None of the above]

Either teach me danish in 10 minutes or... forget it. I'll try to find a test I understand.

Maybe, one day I'll be the conquistador of all IQ tests.

Belated congratulations on achieving a good score.

The link doesn't work, some stupid referrer-based redirect. Hm. Go here -> http://mensa.dk/testiq.html and click the button at the bottom of the page that says "start testen". Beyond that, you should do fine on your own, since it's just a bunch of shapes and stuff. When you're done, click menu and send.

It's not under superivised circumstances, so it will only indicate your IQ.
