'It's actually illegal to use IQ testing' Jordan Peterson on general cognitive ability tests

In this lecture, he talks about Big Five trait openness to experience, which is the dimension composed of an amalgam of creativity and intelligence. he also discuss IQ: how it is measured, what it means, how powerfully it predicts long-term life success, as well as the highly skewed Pareto distribution of creative production.

It's illegal for corporations to use IQ tests.

So they have universities do the IQ test for them, and then hire people based on the Universities. It's not like the education at one institution is going to be hugely better than at another. A lot of high-profile universities like MIT have some very bad professors - because they're there to do research, not to teach. Great professors, bad teachers is actually more common the higher the school gets ranked, generally speaking. Which means that while the science coming out of the laboratories are great, the students coming out of the school are only great because they were selected on their greatness before coming in. They'd actually be better scientists and engineers if they went somewhere else with better professors.

I love how he can be brutal, but only playfully to make the class laugh. Makes him seem like a very engaging professor.

This comment section is almost as painful to read as those facebook posts where they tell you to perform basic arithmetic and 2/3 of the responses fuck up the order of operations, then defend their stupidity as if it were a loaf of bread they purchased with a wheelbarrow of devalued Deutsche marks.

I thought the right part was part of the puzzle and was trying to see how the numbers correlated with the dots and shapes. Guess my IQ is zero.

[keenanmclean]

4:19 "isn't that dismal and wretched...? but its true." That is essentially Jordan Peterson's whole message in a nutshell.

it's p dunning kruger in this comment section lmao

Anyways, is it just me, or is anyone else also terrified of IQ tests? I'm convinced that a person with an IQ of 100 can never be an astrophysicist or anything notable, so the entire idea that I can find out where in the intellectual caste I reside and therefore estimate what I can and can't do hits me in an existential kind of way. I would rather believe, even if irrationally, that I can do whatever I want if I put my mind to it and if even I can't, I would rather try and fail forever like a stubborn idiot trying to defy the laws of nature.

@ 03:53 every shape(triangle, rectangle vertical, rectangle horizontal) appears exactly three times in blue/black/yellow. that's the reason why number three is correct lol.

[szymonskrabanek]

I'd choose #3 for the last one.

If you look at the whole matrix, you can see that there's 3 sets of each color of each shape. So 3 of each color triangle, 3 of each color horizontal bar, and 3 of each color vertical bar. Taking that into account - what's missing?

There's only 2 black triangles, so the missing triangle must be black. That leaves us with #3 or #5. Similarly, there are only 2 blue vertical bars, which already narrows down the choice to #3. The missing yellow horizontal bar only confirms the choice.

[wakeupscreaming]

In my entire work history of 25 years, i've only had one job interview that had me fill out an IQ test. It was in Vancouver, Canada and I can't remember the companies name, but it was IT related.
It was actually just for a graphics job, but they must have made it standard testing for their programmers and engineers they hired.
The HR lady gave me the test before I was to speak to the graphics dept manager. I overheard him talk with the HR lady, and I heard him say "I don't want him here.", and she replied, "But he got a very good score"...
Of course I didn't get the job. Most of my life, I've had way more "no's", than actually job offers.
My experience 99% of the time, is that managers want dumb workers, not smart workers. Sorry, but that's been my truth for 25 years of my working life.

3:39 the answer #3 looks wrong . Reason1 Top row and bottom row both have a vertical line of matching colour in sequence . Reason2 top row and bottom row have horizontal line match in there own sequence . Answerer #7 looks better

[NuklearFusion]

Glad I found this video. I did this nearly identical test as requested by the local court system. I wasn’t sure what it was or why it was needed.

[BostonCasey]

On the third and hardest test i could argue the answer is 7. each row has one of each colored triangle, narrowing it down to a black triangle missing. Both the horizontal lines and vertical lines have 2 of one color, and 1 of the another on each row. 7 Fits this pattern.

[maxefrat]

I think that what people are not understanding is that just because you found an answer that satisfies some true pattern, does not mean that it is equally as valid as any other potential answer/pattern combination. The way that you derive the rules matter. This is analogous to Jordan Peterson's White-Lie/Black-Truth distinction. The goal is to have something that is true on every level of analysis (or as many as possible), from the smallest relevant one, outward.

The problem with #7 is that you could derive sets of rules that are equally as arbitrary to justify other answers (even if they are not necessarily present as one of the choices. This is not the case with #3. I know this because if you were given this problem and no answer key, the only possible answer would be #3 (Tri: Black | H: Yellow | V: Blue), aka, each attribute has 3 of each color.

This would not be the case for any other answer, because the pattern that you would have to use to justify it would have many other patterns that are equally as arbitrary. The one that people keep bringing up to support #7 is that for both horizontal and vertical bars, there are two of a color in every row and every column, and then one of another color. Well, by this rule, there is no difference between #7 (Tri: Black | H: Blue | V: Yellow) and the potential solution (Tri: Black | H: Blue | V: Black). Furthermore, and perhaps more importantly, there is no difference between this set of rules and many other set of rules, in terms of how arbitrary they are. You could also say the rule is that going from bottom left to top right, there is one of each color for each type of bar. Now, you would just get #3. The point is that there is little that can distinguish these two sets of rules, and many others. It's trivial whether or not answers that can be derived from parallel rule sets are actually present. Rather, their mere existence makes the rule set (and corresponding answer) inherently weaker.

I'll end with a very clear example. Here is a pattern:

Pattern: -7, -4, -1, X

Which of the following best takes the place of "X" in the pattern?
A) 2 B) 4 C) -15 D) 0.0714

Obviously the answer is A) 2

Could the correct answer be "B) 4" because all the numbers in the group are drawn using lines?
Could the correct answer be "C) -15" because all the numbers are negative?

Could the correct answer be "D) 0.0714" because the pattern is to multiply 7 by 0.5714, then multiply the resulting number by (0.5715 - 0.3215), then keep subtracting 0.3215 from the last coefficient? (i.e. 4 = -7 *0.5714, then -1 = -4 * (0.5714 - 0.3215), then 0.0714 = -1 * (0.25 - 0.3215))

Is "A) 2" wrong because it does not conform to the rules that can be pointed out in answers B C, and D?
Is this a poorly designed question because there are multiple patterns and prioritizing one must be arbitrary?

The answer is only "2" here for all the same reasons as the earlier problem. "4" is not a good answer because there are many potential answers that are written with lines.
"-15" is bad because there are many negative numbers.
But wait, what about 0.0714? That multiplication rule only results in one potential answer. The problem with it, however, is that there are an indefinite amount of similarly derived rules. Why prioritize this rule when you could prioritize a rule that is derived from division instead of multiplication?

This leaves the most logically consistent rule to be "Add 3"

[knowledgeeverything]

I’m pretty sure the answer is #7 on the 3rd question. It fits every pattern. Black triangle because it’s the only color not used in the row. Blue horizontal line because the only other choice for vertical line only leaves the opportunity to break the pattern of 1 to 2 color ration in each row. 5 would cause all three colors to be used in the horizontal pattern and 3 would allow the same in both horizontal and vertical line. 7 does not break the pattern.

[nanowasabi]

I was looking at the thumbnail trying to solve it, and I thought that the right side was the key telling us which shape signified which number and that I was supposed to find the number pattern on the left, find the logical next number in the pattern, and then retranslate it back into a shape.

This is why you read the instructions.

[GalaxyPedlar]

I came up with 5 for the last one. Black triangle because triangle color is unique in each row. Yellow and black cross because in the other rows, each has three bars of one color, two bars of a second color and one bar of a third color. Selecting either 3 or 7 would give you 2 bars of each color.

[CohibaSkeeza]

4:00 is #3 and here is the actual reason why. I have read some explanations here which are wrong.

1) We know it is a black triangle, so #3, #5, #7.
2) We know it isn't #5 because a) all the triangles in the final column have a combination of the opposing colors b) because each triangle color has the various colored rectangles arranged only once either vertical or horizontal.
3) That leaves only #3 because the other black triangles have a vertical yellow and a horizontal blue, so it has to be vertical blue and horizontal yellow.

[MarcinP]

The first two examples train you to look for rows, third one flips the rules on you.
People who know patterns can be diagonal will have an advantage. It's called rehearsal effect.
You can improve your IQ scores by training.

[QWERTY]

Im so good with these tests(and Lingual ones) but sth about math just makes my brain go like "FORGET IT, SKIP THE QUESTION, THERE IS NO TIME !"

[jimmyp]

Once your understand how to solve it its super easy. It like reverse engineering once you get the first answer then just figer out the why. Same thing for math once you have the answer to one and know the steps for getting to the answer. You just keep working the problem till you get that answer. All about understanding. At atleast untill teacher tells you ur are wrong. even though you get the answer everytime. Alot of teacher just go off the leason plan in the book but dont understand it themselves.
