- Comment on The torque better not be too strong with this one 5 days ago:
It is a curious fact, and one to which no one knows quite how much importance to attach, that something like 85% of all known worlds in the Galaxy, be they primitive or highly advanced, have invented a drink called jynnan tonnyx, or gee-N’N-T’N-ix, or jinond-o-nicks, or any one of a thousand or more variations on the same phonetic theme. The drinks themselves are not the same, and vary between the Sivolvian ‘chinanto/mnigs’ which is ordinary water served at slightly above room temperature, and the Gagrakackan ‘tzjin-anthony-ks’ which kill cows at a hundred paces; and in fact the one common factor between all of them, beyond the fact that the names sound the same, is that they were all invented and named before the worlds concerned made contact with any other worlds. What can be made of this fact? It exists in total isolation. As far as any theory of structural linguistics is concerned it is right off the graph, and yet it persists. Old structural linguists get very angry when young structural linguists go on about it. Young structural linguists get deeply excited about it and stay up late at night convinced that they are very close to something of profound importance, and end up becoming old structural linguists before their time, getting very angry with the young ones. Structural linguistics is a bitterly divided and unhappy discipline, and a large number of its practitioners spend too many nights drowning their problems in Ouisghian Zodahs.

There’s an opportunity cost associated with using land for parking
That’s not a cost of provision. Who’s to say that the medical benefit of many friends or relatives visiting is worth less than a house. Their is an opportunity cost of not having parking.
- Comment on The European mind can't comprehend 1 week ago:
The provision of parking is expensive
No. It’s practically free. The maintenance is just some white lines every few years.

I was asking for clarification. Do many games really add the % to x25?
- Comment on Percentages 2 weeks ago:
Games use x25% or x25? Technically the first divides the score by 4.

Agree with all of that. What annoys me is when properties of the normal distribution are used as “facts” about human intelligence.
I’m sure there are more people with 200+ IQ than with <0.
Reread my original statement and see if you still disagree
- Comment on brains! 3 weeks ago:
It’s pretty obvious that a rock can’t have an IQ of anything but zero.
- Comment on brains! 3 weeks ago:
This is repeating the same confusion.
Calculating values from the normal distribution tells you nothing about the tail properties of human intelligence.

There are many more people in the world who deserve greater care than 1st world plate carriers.

I’d like to hear your explanation how an IQ of above 200 is possible and what that would actually mean.
It means that the mean and standard distribution have been calibrated to a population, but that the population kurtosis is significantly non-normal
Its only possible if there are about 10x more humans.
Incorrect. It’s also possible if human intelligence isn’t normally distributed.
With a population of around 80 billion, the smartest one person would have a z score of roughly 6.6 and an IQ of roughly 200. This is calculated from a mean of 100 and a standard deviation of 15, which is how it’s defined.
Only if intelligence of the human population is normally distributed.
So, as I’ve been saying, you just put everyone’s test scores in order from worst to best,
No you don’t. You have invented this unnecessary step.
calculate the z score of the person you’re interested in, multiply by the SD (15) and add the mean.
No, because the “person” and the z score have no link.
It is also the case that for populations over 80 billion, you can have negative IQ scores, using the same logic that was used for a person with an IQ of >=200.
If a rock has zero intelligence, how can something score lower? Negative intelligence is impossible.

Let’s focus on one individual then with an officially calculated IQ.

IQ is not normally distributed. It can be higher than 200. It can’t be negative.
- Comment on brains! 3 weeks ago:
IQ is defined statistically.
Yes, a ranking. Ideally the same test for the whole population.
Then you use a defined mean and SD to determine …
Here is your error. Limiting the description of the population distribution to only 2 parameters severely restricts the range of distributions that can be selected. Forcing the population distribution to be Normal is done for arithmetic convenience only. Not because intelligence must be normally distributed.
- Comment on brains! 3 weeks ago:
I’m struggling to see how a negative IQ can be practically assessed.
- Comment on brains! 3 weeks ago:
any article that lists historical figures with even estimates their IQs can be discarded as bullshit.
There are people alive on that list.
IQ is a borderline pseudo science
Dude, you are the one trying to prove it’s legitimacy with normal distributions and confidence levels.

In the US, if you are never going to return to an establishment, why tip?
- Comment on brains! 3 weeks ago:
No one has an IQ of 200
I linked to a list of many examples
this has a z score of 6.33.
Only if normal distributions are assumed. Clearly this assumption is incorrect.
But we do agree that a negative IQ is impossible?
- Comment on brains! 3 weeks ago:
If IQ is truly a normal distribution
It’s not. Here’s a list containing a number of people above 200.
However, no-one has a negative IQ.

They have viewpoints on topical application of fluoride and lack of effect on teeth after swallowing.
What bodies of evidence are contradicting these opinions?
