that is enviroment

even with a clear method you can't say, its the scientific method,

You make an assumption (hypothesis)
Test it, and see what comes out
If it correlates with what you expected, and happens every time, you have scientific evidence

I think it's difficult to even tell what environmental factors are important towards that. I remember reading that whether or not a baby is breastfed by their biological mother can have an effect on their IQ, and that this difference is noticeable even if any certain child received breast milk from someone other than their mother

man everything can effect iq

age of the mom

amount of hammers to the face

siblings, quantity and age difference

kindergarden

the idea is that genes provide a maximum, and then enviroment diminished it a lil or a lot

but those are individual values

if you however take a sample of 1000 people, and take the average of their IQ scores, you get an average to work with, and can then set categories

also how do you separate IQ from simply not knowing something, being bored, etc.

you do it by taking larger samples, so you try to eliminate most outlying variables

for example, if I remember right, one of the important qualities of an IQ test is how fast you complete it

depends on the test

could be

there are people who test, who are good at taking tests or who just have that knowledge, like for example if you don't know something just skip it immediately go to the next thing, don't spend 5 years on it

Speed, Answers correct, and the age of the person

myself for example, I'll finish it until I have an answer and I might even check over it if I was unsure

but doing that would make for a lower score, ie. it's more intelligent to just skip it, come back later, then give your best guess rather than trying to figure it out then and there

if you're just there taking a test though, are you really thinking about how to absolutely crush this test into the dirt?

that's just that one aspect. there's other elements, too (which I think have their own ways of being handled). ex. those people who freeze when it comes to taking tests

the data shows that the more intelligent you are the more likely it is you will crush a test

pretty much every competence related task is "g loaded"

which means higher in general intelligence people complete it better/faster

general intelligence is measured with an IQ test

thats why its an intelligence quoefficient

also I wonder things like the level of their general intelligence vs being motivated, or working with things they're intimately familiar with

yes, but this is why you have to take large samples

if 1/10 people are affected by it, then you can still say with 90% confidence the rest aren't

well, I didn't mean that in terms of how it affects general IQ, but rather.. if you accounted for those elements as if they were a separate IQ, what would the differences between those two scores be

per individual, massive

for a sample size, it becomes less significant

the larger your average, the less influence a single outlier has

i mean its the "outlying statistic" argument

If 1 person earns 1,000,000 dollar per month
and 1,000,000 people earn 1 dollar per month,

The average of the 1,000,001 sample you took will be just above 1

this is why sample sizes absolutely matter

cuz if you have a sample of 2 people

1 person earns 1,000,000
1 person earns 0

The "average" person earns 500,000

im off to bed gn

not getting enough sleep decreases IQ!

unless my math is wrong, in your first example the answer would be pretty much 2

well yeah, 1.999998 or something
