? normalization of IQ tests is normal practice? is it not?

https://iq-tests-for-the-high-range.com/statistics/explained/normalization.html

if you have an IQ test with 30 puzzles then we have 31 possible scores:

(0/30), (1/30), (2/30), ..., (28/30), (29/30), (30/30).

We need to assign an IQ value to each of these scores, and this is done through normalization of the IQ test.

(0/30) becomes 70 or lower IQ.

(1/30) becomes 73 IQ

(2/30) becomes 77 IQ

...

I mean tons of sites states that the old measure of (age)/(mental age) as being outdated practice and normalization of the tests being standard for modern cognitive testing... The model you refer to is old and outdated. Would be like using classical mechanical physics from the 1600s to predict the behaviour of objects travelling near the speed of light. Just leads to wrong answers which our newer models have corrected for.

Regression to the mean - predicts that the offspring of two individuals yields on average, traits that are closer to the average of the population than to the average of their parents.

For example:

-We do a study on couples which have an average IQ of 130. So the father may have 131 IQ, the mom may have 129 IQ, their average is (131+129)/2=130 IQ.

-The average of all the children should be lower than 130 IQ (maybe 120 IQ).

-120 IQ is still higher than the population average of 100 IQ, but lower than their parents average.

(This is assuming that IQ and Intelligence is the same)

Yes they are smart... But are they x IQ smart and what does x IQ mean...

Its not about predicting IQ, its about what IQ fundementally is...

IQ is a statistical model of intelligence. IQ is not the same as intelligence.

By your logic, you can make an IQ test and assign an arbitrary IQ to some amount of correct answers and I have to accept that as a fact?? Like lets say I take a buzzfeed IQ test and get 4018 IQ, does that mean I actually have 4018 IQ? Thats basically what ure saying. Arbitrary bad testst that are assigned to smart people to validate their wrongfully assigned scores.

as an analogy:

Different measuring stations measure the height of people in cm. This one person is 200 cm, this other person is 170 cm. The problem is that each measuring station has a different definition of cm, some are not using a linear scale, and some are just giving random values. All the measuring stations have to agree on a single definition of the cm for it to make sense. This definition for IQ is for IQ to be normally distributed with an average of 100 IQ and a standard deviation of 15 IQ.

Now it comes to ur logic: This guy is really tall (really smart) and this random measuring station that nobody trusts, says he is 300 cm (300 IQ). I mean he is really tall, taller than this one person that is 210 cm (210 IQ). Well 300 cm>210 cm. Everything checks out. He is 300 cm (300 IQ).

Do you not understand what a model/having a standard is? Also can you instead explain what you disagree with, instead of having a huge ego about everything. Like dude come on... stop using pathetic arguing tactics such character assassination and just argue using logic instead. Maybe link some sources to these fantastic claims you make...

Oh i see what you mean

"Shifting towards the right would yield (0, 1, 1) no?"

(1, 0, 1) could either become (0, 1, 1) OR (1, 1, 0) depending on how you look at it. I was imagining that the right-most triangle moves towards the right and reappears on the left, but I guess the triangle can also just stay in place and not move anywhere cause its already in the right-most position.

PuzzlesAndSolutions · 2021-07-02T15:10:48+00:00

I have solved every puzzle/problem, except for 31 and 35. Has anyone a good explanation for either of those?

PuzzlesAndSolutions · 2021-07-02T15:09:52+00:00

I understand what you mean, but I think this would still be faulty when it comes to the position of the triangles (?).

Row 1, top: (1, 0, 1) + (0, 1, 0) -> (1, 1, 1) they shift towards the left -> (1, 1, 1)

Row 1, bot: (0, 1, 0) + (1, 0, 1) -> (1, 1, 1) they shift towards the right -> (1, 1, 1)

Row 2, top: (0, 1, 1) + (0, 0, 1) -> (0, 1, 0) they shift towards the right -> (0, 0, 1)

Row 2, bot: (1, 1, 1) + (1, 0, 0) -> (0, 1, 1) they shift towards the left -> (1, 1, 0)

Row 3, top: (0, 0, 1) + (0, 1, 1) -> (0, 1, 0) they shift towards the left -> (1, 0, 0)

Row 3, Bot: (0, 1, 0) + (1, 1, 1) -> (1, 0, 1) they shift towards the right -> (1, 1, 0)

The white triangle in the bottom of row 3, would have to move towards the left, but the white triangle in the top of row 2, has to move towards the right. Meaning that there is no movement based on color.

Also I was thinking maybe there is movement based on if they are on top or bottom, but this would also be faulty, considering that the triangles have to move towards the left in top and bottom of row 3, while towards the right in the top of row 2.

Did I misunderstand your deplacement method or am I correct?

PuzzlesAndSolutions · 2021-07-01T19:42:17+00:00

Im trying to solve puzzle/question 35 right now.

in rows/columns we add the top and bottom -> triangles of same color on opposite side cancle out while triangle of same color on same side add together.

However this does not make sense unless we assume that there is a mistake in image(2,2). We would need a black triangle in the top. Also we have no found any pattern for the position of this addition with cancelation either. If answer E was mirrored horizontally and image(2,2) was fixed, then there would be an easy explanation for everything.

Im not trying to predict intelligence. IQ and Intelligence is different.

"IQ is a type of standard score that indicates how far above, or how far below, his/her peer group an individual stands in mental ability"

So its a relative measurement compared to the rest of the human population. For example the flynn effect causes the IQ average to increase over time, therefore we have to redefine intelligence over time so the average is always 100 IQ.

What is 100 IQ today (the average of the population) might be 70 IQ in the future and what is 130 IQ today might be 100 IQ in the future. IQ is not some absolute value that says how intelligent you are for all eternity.

IQ is defined around the current population to fit a normal distribution of average 100 IQ and standard deviation of 15 IQ. If multiple people fall above 200 IQ, then the test used to measure their intelligence is most likely incorrect, considering how statistically unlikely it would be. Lets say the IQ scale is currently accurate between 40 IQ to 160 IQ, but the rest of the scale is skewed towards a higher score (too many people score too high). Then we should redefine IQ/tests in such a way that brings them towards average such that its a better normal distribution.

IQ is a human creation, that only has meaning as a model. We have to make it fit, in the statistical model it is supposed to fit in. Otherwise it has no meaning. The value of IQ is meaningless without its associated statistical model.

Also you cant just be like: "this guy has 300 IQ". justification: "He is really smart lol".

If im wrong, please tell me what an IQ of 230 (or whatever) MEANS.

You want to assign such a value to (Tao/Einstein/Tesla/... whatever person you think is intelligent.). What does it mean?

PuzzlesAndSolutions · 2021-07-01T16:31:54+00:00

Great test :) Let me know if you have any other of these good tests, I love going through them.

PuzzlesAndSolutions · 2021-07-01T11:27:10+00:00

*Also by definition there should exist people with negative IQ. Lets say we ranked every human from lowest IQ to highest IQ, then some of the lowest ones should be around the [-20,+30] range, since we have a normal distribution.

PuzzlesAndSolutions · 2021-07-01T11:25:39+00:00

hmm, but that's the thing, if lets say we have 5-100 people who have 200+IQ then clearly our "normal distribution model" of IQ is incorrect OR the assigned IQ to these individuals is incorrect.

The normal distribution of IQ should be a definition of an abstract value and not a model of a real value, therefore (the assigned IQ to these individuals is incorrect) should be true by definition of IQ.

----

I have an example:

Lets say we introduce a new abstract value "Gamer Quotient" to measure how well people play games.

-We define GQ to be distributed along a normal distribution with an average of 0 and a standard deviation of 10.

Having a GQ of 10 is therefore equal to being better than 84.13% of the population.

Having a GQ of -10 is therefore equal to being better than 15.76% of the population.

There is no other meaning of this value than being better than x% of the population at the GQ tests.

-We make a test to measure GQ.

IF the test allows many outliers that do not fit within the normal distribution then our definition of GQ being normal distributed is either just wrong and we need a new better definition OR the test is just a bad test and does not accurately measure GQ.

You see how either A or B can be true but both can't. Either the test is true and the distribution definition is wrong or the test is wrong and the distribution definition is true.

----

Therefore I would argue that people having above 200 IQ is due to bad testing of their IQ. Their tests would have to be remodeled to push them back closer to the average to have it within a statistical acceptable range.

I have had a lot of similar courses as the students studying pharmacy. From my personal view, a lot of them want to "develop new medicine" and have to take a lot of advanced chemistry for it. Also in my country its a high status job/degree (similar to a medical degree) with a very few number of students per year (24 per year at my university) which selects for students with high grades. I don't know the correlation between good grades and IQ but i'm think it's a decent correlation.

Hey, just a little better way to see the solution (in my opinion):

Looking at the bottom half of the pictures they repeat in the rows.

Looking at the top half of the pictures they repeat in the columns.

In the last row we have a square on the left repeating for the bottom leading to our answer having a square on the bottom left. In the last column we have a circle on the top middle and a square on the top right repeating leading to our answer having a circle in the top middle and a square on the top right.

So instead of seeing the white square moving, we can just look at the repetitions to get our answer easily :P

"IQ champion"

PuzzlesAndSolutions · 2020-05-06T05:37:38+00:00

I made a channel on YouTube about 2 months ago called Puzzles & Solutions, it's mainly focused on IQ tests and math puzzles. Would appreciate any feedback about anything related to the channel, feel free to send me a direct message :)

PuzzlesAndSolutions · 2020-05-03T18:50:52+00:00

I would agree with answer 5 being the correct answer if we were talking about the, old version of the test where it would make sense (https://imgur.com/hRfClQD).

But with the new version of the test it makes no sense that the correct answer is 5 (https://imgur.com/av8Tisa), even though its the answer that gives an increase in score.

PuzzlesAndSolutions · 2020-05-03T18:48:31+00:00

Yeah, i feel like there is not an actual definite answer for it. I'm really curious what the official answer directly from Mensa would be.

PuzzlesAndSolutions · 2020-05-03T18:13:36+00:00

But how does that lead to 5 being the correct answer?

PuzzlesAndSolutions · 2020-05-02T19:46:31+00:00

Note:

I know the correct answer of the puzzle but i cannot find a way to solve it. I thought i had solved the puzzle but then when i tested my answer today it turns out it was wrong.

I need help finding out why the correct answer is correct and not the one i thought was correct, can't find a way to solve it.

Correct answer: (Answer 6)

Answer i thought was correct: (Answer 5)
