I.Q. as a measure of intelligence is a myth...,

  • We propose that human intelligence is composed of multiple independent components
  • Each behavioral component is associated with a distinct functional brain network
  • The higher-order “g” factor is an artifact of tasks recruiting multiple networks
  • The components of intelligence dissociate when correlated with demographic variables
What makes one person more intellectually able than another? Can the entire distribution of human intelligence be accounted for by just one general factor? Is intelligence supported by a single neural system? Here, we provide a perspective on human intelligence that takes into account how general abilities or ‘‘factors’’ reflect the functional organization of the brain. By comparing factor models of individual differences in performance with factor models of brain functional organization, we demonstrate that different components of intelligence have their analogs in distinct brain networks. Using simulations based on neuroimaging data, we show that the higher-order factor ‘‘g’’ is accounted for by cognitive tasks co-recruiting multiple networks. Finally, we confirm the independence of these components of intelligence by dissociating them using questionnaire variables. We propose that intelligence is an emergent property of anatomically distinct cognitive systems, each of which has its own capacity. cell |

What i do not understood is if truth be told how you are
not actually a lot more well-preferred than you may be now.
You're very intelligent. You recognize thus significantly relating to this topic, made me personally consider it from numerous varied angles. Its like men and women are not interested except it's one thing to do with Lady gaga!

I don't know whether it's just me or if everyone else encountering issues with your website.
It seems like some of the written text in your
posts are running off the screen. Can someone else please provide feedback and let me know if this is happening to
them too? This may be a issue with my web browser because I've had this happen previously. Thank you

Some people in our educational system have worshipped IQ. They treat 130 as a magic number. Like 129 is hugely different from 130. It is useful to simple minded bureaucrats.

C'mon dood..., that rabbit hole goes a WHOLE LOT deeper than bureaucratic simple-mindedness

No doubt. Who has time for all of the rabbit holes. But all you have to do is look at how different computers perform on different benchmarks to see that boiling intelligence down to a single number is ridiculous. But it makes things simple for simple minded bureaucrats.
