Problem is I have not yet encountered a single person - not one - who understands g as anonymous does. Everyone uses it as synonymous with intelligence and as a property of the brain and pertaining to individuals, not populations. <br /><br />But it overstates the case for g. "g" is not even a factor, it is a metaphor, a figure of speech, another way of saying "there is a high correlation between scores". To conclude from this that there is an underlying factor is a leap of faith. Ketchup usually shows up with mayonnaise on a hamburger, but doesn't always, and there is no underlying factor responsible for the make up of ketchup and mayonnaise. Since the two usually show up together to then postulate that they are really the same kind of thing would obviously be a leap of faith, a kind of religious thinking. Nor does it gain in plausibility to say they are <i>partly</i> the same thing - that's simply a leap. Yet since multiple kinds of intelligence often show up together - but not always - we feel entitled to say they share an underlying nature, not just partly, but largely. Yet the "not always" should be enough to show that they do <i>not</i> share an underlying nature and appear together for different reasons! <br /><br />The other problem is that the correlation that g represents is vastly, vastly overstated - probably because people want so much to find it. The fact that Jews can score 120 on V and 100 or less on spatial is <i>hardly</i> *high* correlation, and women also have widely disparate scores on subtests, and the Asian difference of 110 on S and between 96-97 on V also tends to support the claim for *high* correlation. And this is populations - examples of individuals with weak correlation are legion! <br /><br />But people see what they want to see.Kernnoreply@blogger.comtag:blogger.com,1999:blog-9430835.post-20578395501376457072013-11-23T11:41:57.860-08:002013-11-23T11:41:57.860-08:00I don´t feel like reading that stuff, but can it b...I don´t feel like reading that stuff, but can it be falsified?Orlandonoreply@blogger.comtag:blogger.com,1999:blog-9430835.post-3751810231764761332013-11-23T11:31:29.973-08:002013-11-23T11:31:29.973-08:00g is a variable that generally explains most of mo...g is a variable that generally explains most of most people's cognitive performance on a range of tests. It explains a large part of the variance.<br /><br />It isn't a variable that explains everybody's performance perfectly. Some people can show very little correlation between tests. It's just that people don't do so often.<br /><br />The problem with how people see g is that they misinterpret it as a statement that <b>*everybody*</b> has to have their cognitive scores on one test within a certain, fairly close, fixed range of certain other scores.<br /><br />But this isn't true. People generally *do* show high correlation but they don't *have* to and some people *don't*.<br /><br />For this to be the case, g has to be a population level abstraction, rather than a real property of the brain.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9430835.post-73466858029937884722013-11-21T21:46:09.421-08:002013-11-21T21:46:09.421-08:00Neal Armstrong had a cool line: "A pessimist ...Neal Armstrong had a cool line: <i>"A pessimist says the glass is half empty.

When working a puzzle it is the mind’s eye that matches up its different parts – it sees those parts meshing. Words define different objects that have grown to be what they are. And words define the different types of movement the effect the future of those objects. These differences are all taken in by the eye and stored in the mind’s eye.<br /><br />The capacity to see something and predict its future is intelligence. That is what should be measured.<br /><br />p.s. Hitting a baseball requires concentration, predicting the movement of planets requires concentration, doing a puzzle requires concentration. Can concentration be taught – can that be learned through effort? <br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9430835.post-33253688226850410232013-11-21T13:50:20.060-08:002013-11-21T13:50:20.060-08:00Seen this one yet, Steve?

We certainly didn't need a new study to show this - existing well known facts about IQ demonstrate this well enough. That Jews could score 120 on verbal and 100 or less on spatial, and a host of similar facts, makes that blindingly clear. It was only the strange conspiracy to ignore these blatant facts that kept the g myth alive. What seems to be changing now is that - perhaps - scientists are beginning to actually come up with theories that make sense of current data lol. <br /><br />g was always a case of wishful thinking and overstretch, a product of the desire to find one overarching factor that explains everything and eliminates messy complexity, which is strong in science, as well a projection of common sense conclusions - we all sort of believe that a single thing like intelligence exists until we examine it closely - onto recalcitrant facts.<br /><br />Now I have only to wait till some g zealot tells me I just "don"T understand" the concept of g. Right, because it's soooo complex. I notice more and more the favored tactic among scientist types who don't want to admit they're wrong is to claim they are not understood. I suppose to an intellectual, the strongest put down is to say you don't understand, and I suppose there is no answer to that because if you didn't understand but thought you did you wouldn't know. But then, maybe <i>they</i> don't understand and don't know. lol.Kernnoreply@blogger.comtag:blogger.com,1999:blog-9430835.post-10410927149309264272013-11-21T10:32:52.538-08:002013-11-21T10:32:52.538-08:00Re: IQ Test

I took courses in statistics, genetics and testing.<br /><br />Everything I learned in genetics was wrong or inadequate. Everything has now changed.<br /><br />Everything I learned in statistics is exactly the same as it was then. Computers do the calculations faster these days but the theory and the tests are all the same. <br /><br />In psychological testing we had the Stanford-Binet, the WAIS, the SAT, and the GRE. All the same. Also the same then was discussion of 'g' versus multifactorial theories of intelligence and the public's discomfort with racial differences in IQ.<br /><br />That's why I try to only read about genetics nowadays. At least there's some new stuff occasionally. These IQ arguments are real nostalgia items like that issue of National Lampoon you ran earlier in the week.<br /><br />Multi factorial IQ. Ahh yes!

Their paper is a sorry example of people using methods they don't understand and then getting published in a journal like Neuron whose editors and reviewers also lack psychometric expertise.<br /><br />Firstly, they make much of the fact that they had (poor quality) test data from thousands of individuals. However, the sample size in the crucial brain scan part of the study was actually 16. Yes, 16. The idea that you could determine anything about the structure of intelligence based on a brain scan of 16 individuals is laughable.<br /><br />Secondly, if you look at the Supplemental Information of their paper, you'll notice that the first component in fact explained a whopping 79.7 percent of the variance in their brain scan data. Similarly, in their online test data, there was a first component that accounted for 27.3 percent of the variance, while the two other significant components together accounted for 17.7 percent. (The fact that the common variance is as low as this suggestst that their test battery has an excessive amount of error variance, probably reflecting inadequate sampling of participants and psychometrically unsound tests.)<br /><br />So, how did they get from these data that are consistent with there being a general factor to the conclusion that there is no such thing? Well, they simply rotated the components so that that the variance of the first component was dispersed to several components. In other words, they mathematically transformed the data so that the large first components went away. This is, of course, a perfectly circular way of claiming that there is no general factor. It proves nothing about the structure of intelligence. They argue that the correlations between the component loadings from the tiny brain scan study and the big online testing sample confirm their preferred component structure, but the correlations reported are 0.79 and 0.64, which means that the loadings are definitely not the same (a <a href="http://en.wikipedia.org/wiki/Congruence_coefficient" rel="nofollow">congruence coefficient</a> of >0.95 is generally the standard for component/factor identity; furthermore, it seems that they mistakenly used Pearson's r to calculate the correlations). <br /><br />Using the very same data and the same sort of reasoning, they could have also concluded that the g factor is real and that intelligence cannot be conceived without reference to g. That would also have been an erreneous conclusion, because their methods and data are completely inadequate for the task of determining the structure of intelligence.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9430835.post-5952771416066567492013-11-21T00:04:58.780-08:002013-11-21T00:04:58.780-08:00"Arthur Jensen is hereby demolished and refut..."Arthur Jensen is hereby demolished and refuted and buried for the 765th time!
