The literature on intelligence is kind of all over the place
Higher intelligence is thought to be linked with more efficient use of resources rather than just faster or slower thinking:
Diffusion markers of dendritic density and arborization in gray matter predict differences in intelligence

But, larger and faster neurons are found in people with higher IQ?:
Large and fast human pyramidal neurons associate with intelligence

More intelligent people have better neurological integrity and their neural impulses travel faster:
Genetics of Brain Fiber Architecture and Intellectual Performance

But, intelligent people take longer to solve difficult problems:
Learning how network structure shapes decision-making for bio-inspired computing

- dilawar 3y agoBoy, this modern obsession with IQ is no less intense than old Indian obsession with purity. The fact that IQ can't be measured or even defined any better than purity does not take the force away. Fortunately, IQ based society looks less evil than prurity based. At least your place in society is not strictly fixed by your birth.
- gmadsen 3y agoIQ(rather g-score) is the most well understood measurement in all of pyschology..
- epgui 3y agoAnd yet it means very little and is a horrible proxy for what we consider “intelligence”.
- justrealist 3y agoIt's an incredibly good predictor of life outcomes.
- pillefitz 3y agoSo is skin color
- badpun 3y agoThat changes from society to society, whereas intelligence as a positive predictor of success is universal.
- epgui 3y agoYou could just replace “skin colour” with “ethnic privilege” or whatever (which is more the point). I don’t know of any societies that don’t have that sort of problem.
- ralfd 3y agoAlso in ethnically homogenous countries?
- pillefitz 3y agoI guess so, looking at South Africa or other African countries where ethnicities with Western features historically got preferential treatment.
- eesmith 3y agoWhich country are you thinking of? Statistics of course can't work if there is no deviation, but I can't think of a country which is ethnically homogeneous. Countries with a high degree of homogeneity, like South Korea and Japan, still have their own forms of racism. For example, https://en.wikipedia.org/wiki/Racism_in_South_Korea https://en.wikipedia.org/wiki/Racism_in_South_Korea says many students "have difficulties maintaining relationships with students who do not share the same nationality background ... because of their classmates' different skin colors".
- shard972 3y agoIQ is well defined and can be measured relatively accurately. There is extremely little chance of someone testing 70 IQ vs 130 IQ is going to be "more intelligent" on pretty much any metric you come up.
- aeternum 3y agoIQ(g-factor) can definitely be measured even though no single test measures it perfectly. If you give reasoning tests of all kinds (verbal, spatial, mechanical, numerical, etc.) there is lots of data showing that the the results of those tests tend to be correlated positively.
