Jordan Peterson Goes Through IQ Test

okay so here's some IQ items so this is this is from a test roughly it isn't from the direct test but it's an analogue of the Ravens progressive matrices now here's how the Ravens was derived so imagine that you have you got your hundred questions and you can take out the some of those and call that IQ okay so now you have a score then you can do a correlation between all of the items and that score and you can find out which single item is the best predictor of the total score because you might see that question thirty nine has no correlation with with the with the mean with the average you say well that isn't a very good question you'd actually throw that out of the next test but you'd say well item number fifteen is correlated at point seven five with the total score so that's a good single item so then imagine that you went across sets of IQ tests and you took out the best single item predictors of full scale IQ what you'd end up with is something like this so the Ravens progressive matrices is a very good test of fluid intelligence and it's relatively non linguistic which is also an advantage right because imagine you wanted to assess the intelligence of a very diverse range of people and they all came from different linguistic backgrounds well as long as they can understand the instructions which are almost self-evident then they're gonna be able to do this okay so this is you see you have to guess in case you didn't already figure this out which you would have had you been using your intelligence and applying it you're trying to replace the question mark with one of these and so here's how you do it roughly speaking it's also a it's probably a working memory test because you have to hold a variety of variables in imagination at the same time okay so the first thing you say see is every row has a star a triangle and a square and each row has a dot two dots and three dots and so every roll has to have a triangle square and star and one two or three dots okay so this one first of all what's it missing in terms of shape triangle excellent see that's why you're at the U of T and then okay and then what's it missing four dots two it's excellent so we do a little scan here and we say oh look well it could be that one or it could be that's it it's that one and so is that right yes aren't we smart no that was easy so no you're not very smart if you figure that one out because pretty much everybody can figure that one out I think this next one is more difficult okay so in the first row you see that there's two objects each or different color and they move together right they join that one they're separate there they join they're together they're separate there and they joined there so this one should be halfway in between those two and the other thing that happens is let's see up this item actually might be incorrectly represented because the blue should be on the other side whatever what's that three yes did they flip okay well anyways you see that it's three see I'm not very bright because I've just lectured for an hour okay so so that was a more difficult item and then this one is more difficult if I remember correctly so let's see so they're all three different colors so that has to be color then what's the other thing and the relationship between the colors change so what's the answer ha you're off you're all scared to answer aren't you because you might be wrong yeah and then there are more anxious people or even less likely to answer number three okay so if you want to test someone's IQ then you put together like nice batch of these at different levels of difficulty and then you sum them and then you rank order and then you correct for age and then you have IQ and that's that and then you can say well then you can sort people into the complexity of their occupations and isn't that dismal and wretched but it's true so here you go this is from the Wonderlic people they're a commercial company that makes general cognitive ability tests and it's often you by corporations even though it's actually illegal it's actually illegal to use IQ tests but the Wonderlic doesn't promote themselves as testing IQ I think they I think it's general cognitive ability which is the same thing but whatever the SATs the GREs the LSAT all of those are IQ tests so now they're more crystallized than fluid and we'll get to that in a minute but crystallized knowledge is what you accrue across time so you could say that fluid intelligence is what programs your brain it fills it with facts let's say it fills it with knowledge and then but you can get an estimate of your intelligence by sampling your domain of factual knowledge and the reason for that is that well obviously the better the programmer the better the content and so what that also means is that you can you could if you were dead prefrontal cortex was damaged later in life your fluid IQ could plummet but your crystallized IQ remained more or less intact so even though they're not different one produces the other and then once the producer has produced then the producer can disappear and you still got the encoded knowledge so at least that's how it looks to me so okay so how smart do you have to be to be different things in life well if you were have an IQ of a 116 to 130 which is 85th percentile and above so it's one person in eighth up to one person in 130 I believe is 85 90 95 is it 95 I think it's 95 one person eight to one person in twenty then you can be a attorney a research analyst and editor at advertising manager a chemist and engineer and executive manager etc that's that's the now that's not the high end for IQ by the way you know that it can go up well it can go up indefinitely although there's fewer and fewer people as it goes up so if you want to be the best at what you're doing Bar None then having an IQ of above 145 is a necessity and maybe you're pushing 160 in some situations and maybe that's making you one person in 10,000 or even one person in a hundred thousand and then also to really be good at it you probably have to be reasonably stressed tolerant and also somewhat conscientious so you know people well you think well why is it that smart people are at the top of dominance hierarchies and the answer to that in part is because they get there first right I mean everything's a race roughly speaking and the faster you are the more likely you are to be at the forefront of the pack and intelligence in large part is speed that's not all of it is so if you're moving towards something difficult rapidly the faster people are going to get there first so IQ of 115 110 to 115 so that's 85th to 73rd to 85th percentile copywriter accountant manager sales manager sales analyst general manager person purchasing agent registered nurse Sales Account Executive if you look at universities the smartest people are there above this who are the smartest people at university what do you think mathematicians physicists and mathematicians right right I could tell you who's on the other end but I won't yeah I'd like to though anyway anyways okay going down the now 103 to 108 is slightly above average right 60th to 70th percentile store manager bookkeeper credit clerk lab tester general sales telephone sales accounting clerk computer operator customer service rep technician clerk typist so you see at this level people are people have some technical skill and some ability to deal with complex things okay that's dead average 100 is average dispatcher in a general office police patrol officer receptionist cashier general clerical inside sales clerk meter reader printer teller data entry electrical helper 95 to 98 machinist food to partner manager Quality Control checkers security guard unskilled labor maintenance arc welder dye setter mechanic good-good IQ range for relatively qualified trades people 87 to 93 messenger factory production worker assembler food service worker nurse's aide wear host Minh custodian janitor material handler Packer now what you're seeing what you're starting to see is that as you move down the hierarchy the jobs get simpler they're more likely to be assigned by other people or they're repetitive because why iq predicts to some degrees how rapidly you can learn something but once you've learned it it doesn't predict how necessarily how well you do at it and so the more repetitive jobs ten people with lower IQs are more suited to more repetitive jobs under 87 is there something well no right that's a big problem and it's something our society has not addressed at all jobs for people with IQs of less than 85 are very very rare so what the hell are those supposed people supposed to do it's like one it's 15% of the population what are they supposed to do well we better figure it out because one of the things that's happening too is that as the as the high IQ tech geeks get a hold of the world the demand for cognitive power is increasing not decreasing right you want to be a teller well you know those checkout machines they're not so simple you want to work at McDonald's you think that's a simple job you don't see robots working at McDonald's and the reason for that is that what McDonald's workers do is too complex for for robots to do so well so this is a discussion that no one wants to have but that's okay it's still a problem and it has to be dealt with so the US government I think I told you this at one point already it's illegal to induct anyone into the US Army if they have an IQ of less than 83 right it's about 10% of the population because the US Army that and they've been doing IQ testing since IQ testing began because they want everybody they can possibly get into the army because in peacetime they use it as a way of moving people up the socio-economic ladder and in wartime well obviously you need as many soldiers as you can get your hands on and so you're not gonna be any pickier then you have to be so when the US Army says it's illegal to induct anybody into the Armed Forces if they have an IQ of less than 83 then you know that they've done it for absolute necessity right and when people have made a finding that contradicts what they want to hear and they're doing it out of absolute necessity you can be reasonably true that it's one of those facts that just won't bloody well go away and so you might think well if there's nothing for someone with an IQ of less than three to do in the army what makes you think that there's something that they can do in the general population and then the issue is you know because the Conservatives will say well they should just work harder it's like sorry that ain't going to fly and the Liberals will say well there's no difference between people anyhow and you can just train people to do everything and that's wrong so they're both wrong and they're seriously wrong and the fact that neither side of the political perspective will take a good cold hard look at this problem means that we're going to increasingly have a structural problem in our societies because we're complexify 'never ething so rapidly that you can't find employment unless increasingly unless you're intelligent you guys are really going to face this you know lawyers are disappearing like mad and the reason for that is you can look it up online increasingly you can do things yourself if you're smart and so like the working class people have been wiped out pretty nicely over the last 30 years by by automation and various other things it's the low end of the white collar class that's coming up next so I'm not saying that lower lawyers are in the low end but low end lawyers are in the low end of the white collar class so there's still going to be plenty of positions for people who are creative and fast on their feet and super smart in fact those people are going to have all the money and that's already happening to a great degree you know cuz if you're smart and you can use a computer you're so smart it's just absolutely unbelievable right and if you can't use a computer and lots of people and I don't mean you know you can open word that isn't what I mean I mean maybe I mean you can program and if you can't program well you're right at the next end so if you haven't got that with you you're you're gonna be left behind
