Is Intelligence Mostly Innate or Nurtured?

Description of question:

Now, it is near common knowledge that there is some level of intricate interplay between innate abilities and nurturing. However, which one plays a larger role? Please post your thoughts on the side that you feel is more responsible for various levels of intelligence in the Human population. If you are of the persuasion that it is 50-50, than please come down on either side or both sides of the debate when posting. Also, do you object to the framing of this question?--and rather feel that there is more to be discussed than explored here? Please indicate as such if you deem this to be the case while stating your reasoning.

Note: We are strictly discussing Human intelligence, as the innate differences between a Human and a frog are rather obvious/trivial to reasonably conclude/suppose.

Response:

A person who is uneducated is very much analogous to stating that they lack physical training. Therefore, their mind is lacks intelligence in a similar manner as ones body would lack strength. Like a muscle, the brain adapts to stimulation and atrophies in the absence of it.

Now in regards to historical figures and intelligence, I will reference a previous post of mine on a separate Forum concerning a connected topic (in hopes that this will contribute to the discussion here):

Now, we need to distinguish between the "hardware" and "software" involved in Human intelligence.

Everybody is born with "hardware" on a spectrum from "lowest grade" to "highest grade", much like height for instance--which is (nearly) entirely out of their own control. Now, unlike height (actually, height can be fiddled with a bit), even the "hardware" can be molded in the positive or negative direction to relevant (although highly constrained) degrees due to neuroplasticity (and Frontal Lobe development or failure to become developed).

As for "software", this is tremendously reliant upon environmental factors and stimuli--including education, study time, ect. ect. Now, there is extremely high reason to believe that average range Human "hardware" is compatible with "software" upgrades beyond what we can currently imagine. That is, we have nowhere near "maxed out". For instance, it is well understood that the modern average Physics Graduate student (who is proficient in their studies) understands Relativity better than Einstein himself did. Moreover, Archimedes, for his time (ca. 287-212 BCE), was an unprecedented genius of the highest degree and it is well understood now that an individual with a BA/BS in Mathematics (that is proficient in the area) has knowledge & abilities so far above Archimedes that if they were to enter a time machine and go back to converse with him, Archimedes would be flabbergasted & almost definitely would struggle mightily to keep up--if he could at all. Archimedes (and others of his time) may well be tempted to describe such a Time Traveler as a "genius", although we know how silly & off the mark this claim would be. Hence, there are differing perspectives at work here as well, and if the Scientific Enterprise continues for centuries to millennia into Humanities future, this dynamic is bound to continue to unfold. This is a strong basis for hope--if humanity is able to "get our act together", then the potential is stupendous.

Also, Einstein (or Newton, ect) would have never been Einstein if it weren't for the extreme grit & tenacity for which they approached problems. Einstein worked on General Relativity continuously for 10 years straight, and in later life ultimately was on his deathbed writing down equations until he died. The idea that it was simply a "gift" is absurd--Newton, Einstein, and others are amongst the hardest-working people who have ever lived (aside from forced labor, that is). This is why comparisons between say Michael Jordan (or other "top" athletes) and Albert Einstein, ect. are truly infuriatingly stupid (amongst many other reasons).

Now, Newton & Einstein were clearly aberrations in the "high-grade Hardware" they were born with--and people with such "hardware" (to that level) seem to be extremely rare indeed (in fact, statistically infinitesimal). However, one should note that they still put in a tremendous amount of work in order to become the top "Genius" level people we know them as today--or else we (likely) would never have known them at all.
 
Well - you don't have to look much further than Donald Trump for an answer. Per some estimates, he has a fairly high IQ but, he clearly either is poorly educated and/or simply chooses not to use his brain in any constructive way...

(Was that too political, should I have not done that..?)

Its the meno's slave by Plato i guess, even though they thought
"he spontaneously recovered knowledge he knew from a past life", he had to be shown how to double a square (not as easy as you might think at first)

Socrates: "can you double this 2x2 square in size?"
Boy: "i just double the sides of the square!!"
Socrates: "No, that will give you a square that is 4 times as big."

Boy: "well... Then i extend them half the size then!
Socrates:" No, that will give you a 3x3 square."

At this point the boy gives up and Socrates have to show him the diagonal approach.

But the fact that the boy did realize the truth and understood the answer at the end was enough for Socrates to believe that the boy had the answer "inside him" from the start.

I kind of agree, i think we are "hard-coded" with math, its just about asking the right questions.

This is only 9 minutes of your life;
its a fun TEDxTalks clip where a mathematician talks about this question "Innate or Nurtured?" he starts with the plato story but you can jump 5min in where he rounds up with a "doodle story"

I find that especially interesting as i too have a similar experience.
(not as fancy, but the doodle from my youth turns out to be an electron diffraction pattern showing five-fold symmetry from an aluminum-copper-iron quasicrystal.)

Maby go check out your old doodles? They might turn out to be something much more than that =)
 
I'd like to write a longer post than this but here are a few thoughts:

1) There is a large body of solid evidence showing heritability of IQ in Humans is somewhere between 60% and 80%. This includes accounting for factors such as how children are raised by parents (which is more of a 'nurture' thing I guess).

2) There is also a large body of very strong evidence showing how early environmental factors can set our brains up for life as being more capable or less capable. If you're exposed to the right factors when you're young, such as languages, music, and books, you build a better brain. Certainly a key period is under 5, but may stretch until the teens.

3) Diet in early life plays a huge factor in brain development. For example, children who get more fish oils will learn to read better. So this is an environmental factor and could also be nurture, but is measurable. Likewise poorly nourished kids grow up with lower intelligence, which is a huge problem in poor countries and poor communities in rich countries.

4) Other environmental factors can have a serious affect on brain development and intelligence. For example, exposure to lead during pregnancy or early life can lose you 5 IQ points. This is why we took lead out of paint, pipes and gasoline.

Now, we need to distinguish between the "hardware" and "software" involved in Human intelligence.

Must take issue with this.
This is fallacious reasoning and you can't draw an argument from it, it's simply not true.

There is no distinction between 'hardware' and 'software' in brains as we know them. There is no 'program' running on a neuronal CPU. Genes from parents cause the initial hardware to grow in the foetus, environmental factors also influence how that hardware expands and is shaped, and sensory inputs rewrite connections in the hardware. Your actions can reshape your brain.

For example, taxi drivers who learn a lot of road routes in a city see their hippocampus increased in size and restructured to accommodate the demands of the job. People who have brain injuries learn to use other parts of their brains to take over functions that normally reside in specialised regions. The brain is constantly rewiring itself shaped by the inputs around it.

Other activities can affect the brain's abilities throughout life:

- Sedentary lifestyles, such as too much TV, may be a factor in the dementia crisis.
- Playing video games may cut the risk of dementia
- Players of Mind Sports (Bridge, Go, Backgammon, Chess and Poker) may cut the risk of Alzheimers and Dementia

Although interestingly, it appears brain training games have no measurable effect on cognitive ability.

If we've produced anything that comes close it'd be a reconfigurable FPGA, that somehow rewrites itself automagically to cope with the task at hand. Our model of computing - hardware, software, memory, storage, is a human invention and not a universal basis for all computing, and does not come close to modelling how a brain works.

Conclusion: it's fairly clear that the brain is shaped by nature and by nurture.

Studies show IQ is strongly heritable, although we don't have a precise number it appears to be between 60% and 80%.

However, the brain changes and restructures itself throughout life, particularly in early life, and IQ changes throughout life as a result. There may be things you can do to increase your IQ, or at the very least, retain your peak IQ for longer than most people are able to in to later life.

Now excuse me while I go play a nice game of Chess.

But IQ doesn't mean anything, its not useful for anything but a instrument we today (should) only use when there is a braindamage, and IQ tests are a part of wider measurements tools in neuropsychology.

IQ and Intelligence has nothing to do with each other.

Its unfortunate that these kind of tests are used in some schools today.
They are however viewed as offensive and we now start to understand its not the children who has learning disabilities, its the schooles.

IQ tests can only measure how good you are at IQ tests... Which does not prove anything more than that.

The answer in this example may be elusive for a kid (or adult) that is not used to look for patterns like this. But its easy to learn the logic.

If i took an IQ test today and lets say i got a score of 100.
Then i could sit down for 1month and study how the logic and the questions was buildt up.
After a month i might score say 132.
Did i jump 32 points in Intelligence?
No...
I only scored better at that kind of tests.

You have a problem with IQ, I can accept that, but I think you're missing the point. It is one measure of intelligence, and particularly recently, there has been some debate around its usefulness, but it remains the most thoroughly researched means of measuring intelligence, and by far the most widely used in practical settings, so it will appear in studies on intelligence.

We have very few other scientific methods of measuring intelligence that deliver a numeric score that can be used in evidence-based studies. Other ways of estimating intelligence correlate quite strongly with IQ, indicating IQ is likely a useful measure, even if not entirely comprehensive as a measure over aspects like creativity or social intelligence.

Regardless, in these studies, scientists are not asking people to practice IQ tests and see if they improve. They are giving the same test to a large control group, just once, and while some of them may have seen these sorts of problems before, this distorting factor would likely be quite small.

So, when I link to articles and papers (or to wikipedia articles that cite those articles and papers) that speak about IQ, you can mostly read them as 'generalised intelligence' (if not specific intelligence) and still derive useful results from them in terms of the nature vs nurture debate, even if you don't believe IQ is an all-encompassing measure, which I don't think anyone would argue anyway.
 
Its the wrong use of these tests and the stigma that follows im pointing a finger at, especially in the educational system.

I agree with you that IQ-tests are one of very few methodes to get to a "number"......

I dont agree when you say "this distorting factor would likely be quite small."
between people who have prior experience with such tests and those who have not.

IQ-tests could be a fun thing implemented in math for youngsters, but..the way they are used, as a mental age meter etc....
i dont think such tests are worth the paper its been written on.
We need to educate people not put them in boxes.
 
Oh I agree on one point - that IQ tests were never designed to be paraded around as some sort of badge of achievement you hang around your neck for someone's life. In most studies like these, they're conducted in a way that the child (or adult) would never even know the result.

They're useful in drawing general statistical trends, but should not be used as evidence (or lack thereof) for individual intelligence or imply limits on personal potential.
 
If a certain someone mistakes a dementia test they've taken for an IQ test and claims that the result shows that they are a very stable genius, what can we deduce about that person?
