Maybe.

Intelligence is nearly completely genetic. Only an unintelligent person would disagree.

Intelligence can be taught but there are limits to the intelligence reachable and different rates of learning depending on the genes. That why a monkey cant be trained to be as intelligent an average human

i think its a mixture of lots of factors.

bullshit, the max intelligence of a monkey is like 60 IQ or a bit more, like a retard.

>>4343535

oh shit, i read can instead of cant. you got it man, sorry for the bullshit part.

Most of the variance in IQ amongst adults within developed nations can be attributed to genetics.

I thought that was the average IQ of sub-saharan Africans.

>This statement outlines conclusions regarded as mainstream among researchers on intelligence, in particular, on the nature, origins, and practical consequences of individual and group differences in intelligence. Its aim is to promote more reasoned discussion of the vexing phenomenon that the research has revealed in recent decades. The following conclusions are fully described in the major textbooks, professional journals and encyclopedias in intelligence.

[...]

>Individuals differ in intelligence due to differences in both their environments and genetic heritage. Heritability estimates range from 0.4 to 0.8 (on a scale from 0 to 1), most thereby indicating that genetics plays a bigger role than does environment in creating IQ differences among individuals. (Heritability is the squared correlation of phenotype with genotype.) If all environments were to become equal for everyone, heritability would rise to 100% because all remaining differences in IQ would necessarily be genetic in origin.

If intelligence isn't genetic, then I dare you to raise a rock. Checkmate.

>I thought that was the average IQ of sub-saharan Africans.

If you go by Richard Lynn's estimate, the average is around 67. If you go by Jelte M. Wicherts' estimate, the average is 82.

Alot of people have a completely different intelligence compared to their parents... dont think its THAT related tbh. Anyone has any recent studies that say otherwise?

Apparently genetics determines your potentiality, or ceiling.

In your formative years, your current intelligence is hardly genetically related and heavily weighted toward the effects of "nurture" and teaching and following examples etc. etc etc.

But in your adult life, your intelligence ceiling is more manifest, and is maybe half-related to your prior schooling/training and half-related to your genetic lineage determining your mental capability.

capuchino monkeys, the most intelligent ones, have the intelligence skills of a 3-years-old. i think thats a bit lower than 60. anyone knows?

There is no doubt a genetic factor when it comes to intelligence but, overall, nurture has, by all appearances, a far greater effect than nature. Access to better nutrition, an environment that encourages intellectual growth, and access to information/education can cause someone whose IQ is previously tested as in the 80s to rocket to the 120s in the span of a few years. This has been demonstrated by what happens when children from poor homes are adopted by wealthier families, and is largely why I am in favour of gays being allowed to adopt (along with the whole "No good reason to deny them" part).

But at the end of the day, intelligence is so much dick-waving. We have no quanta by which to judge intelligence beyond results. Even then, there's different areas of focus for intelligence that can leave someone amazing in one field and terrible in others.

At the end of the day, if we provided every human being with good nutrition, good education, and good incentives to achieve, you'd see the average level of intelligence and discourse shoot up with no change to genetics.

As far as the variance in IQ amongst adults in developed nations are concerned, nutrition and and parental socialization are minor factors. In fact peer-group influence is probably a more significant environmental factor than either parents or nutrition. Studies on learning-intensive highly-structured environments of young children from extremely bad backgrounds show significant gains early on, but these large gains tend to be short-lived as the environmental variance in IQ for children is higher than for adults.

Interesting... Did these studies continue to follow these children into their adult lives and test them again later, to see how they did later on?
