Why isn't IQ a number from 0 to 100, instead we have this stupid range for whatever reason.

IQ doesn't follow normal distribution.

It's interesting that other scores such as SAT, ACT, and FICO don't have zero as their minimum but they all have a maximum, while IQ has no maximum but zero is minimum (probably only achievable if brain dead).

Just use terf(x), the gaussian error function offset to unbalanced trits {0,1,2} and multiply by 50.

I believe they enforce a nonuniform scaling to force the distribution into being a gaussian because gaussians are easy to understand and work with since the mean and variance is all you need to know the distribution completely. We have lots of methods to deal with Guassians since they are fundamental thanks to CLT.

For ease of use, as >>16365894 said, IQ distribution are often VERY skewed on one tail or the other, which implies that there additional assumptions to be made on how intelligence is distributed. To be more precise, a gaussian emerges when either: 1.. is the limit of a binomial distribution 2. When you only know the mean and variance, this is the closest apporximation you can ever get. 3. Central limit theorem: the sum of independant events that all follow the same distribution tends to a normal distribution.
Of course, if you add extra conditions on top of it, it's no longer a normal/gaussian distribution

IQ doesn't have the same maximum as temperature, OP. You can always find a smarter person.

It would be interesting to see a set of fifty short interviews with each 2% segment of the distribution. What questions could be asked to best demonstrate the essence of each slice?
Ryan Cooper at Sat, 7 Sep 2024 17:35:37 UTC No. 16366163
Probably they made it so the average will be 100. (However people slowly get smarter over years, so probably 100 is not average anymore)

False. The average Canadian has a higher IQ if he is replaced by any average immigrable poo.

And? If a person moves from one country to another, average human intelligence doesn't change. In many cases immigrants need to be smart to move somewhere and find a job

Wrong, people just learned how to do IQ tests better and how to imitate intelligent stereotypes in public, they are still retarded thougheverbeit.

(100+95+105)/3=100
Now add in some 80s.
(100+95+105+80+80)/5=92

IQ scores below 60 or above 160 are almost entirely meaningless, you are splitting hairs so fine the entire result is noise and thats assuming IQ is a serious measurement in the first place.

This is true. When I had to go to IQ Fitness Camp the first time, I was scared but then my mother told me IQ Fitness Camp is where she met my father. Lots of people meet their spouses that way as IQ Fitness Camp is mandatory for everyone so everyone can learn how to get higher scores on IQ tests. By the seventh or eighth time at IQ Fitness Camp, I was no longer scared and knew it was for the best that we all attend annually.

It's not, though. In principle, given a large enough population and a sufficiently calibrated IQ test, you could measure IQs over 200 and below zero.
In practice, a world population of 8 billion means the range of IQs _should_ extend from 5 to 195 -- but any IQ test has a much smaller range of valid results, because it can't be calibrated on anything like the entire population. As other posters have said, typically 40-160.

I know IQ is a relative measure normed to a particular time and place, meaning a test result from Norway in 1979 can't be meaningfully compared to a result from Ghana in 2021. I also know about the Flynn effect and such.
But why do it that way? Why not just pick one test and one norm- let's say a widely known, well-studied, culture-independent one- and use that everywhere forevermore? Then you could easily demonstrate changes across time and space.
