What's more interesting to me is the fact that people are still sticking to this idea of expressing one's intelligence with one number. Just one. Using IQ as the degree of intelligence is like using one's weight or blood pressure as the degree of healthiness. It may be an important metrics, but only one of million variables.
- haihaibye 7y agoIt's not one of a million metrics, it's the best possible summary of all the metrics: * There is very high correlation between different cognitive tests (people who are good at one test tend to be good at others) * If you perform factor anaylsis, you can compute a common factor that can be regarded as a summary variable for the correlations between all the different tests. * This is the g-factor, or the single number produced from IQ tests.
