Is a persons intelligence genetic ?

[The Diplomat]

Part of it is genetic, part of it is environmental

Aye. Like with most things, it's nature vs nurture. One may have the ability through genetics, but may never reach their full potential without proper education and the right kind of training/teaching.

I would say mostly genetic. Two parents that are bad at math, usually don’t have Matt Damon in Good Will Hunting.

Who's to say that doesn't have a lot to do with the environment dummies create for their children? Same with fat people. Is it that you just have fat genes, or could ordering pizza 5x/wk and have cupboards filled with chips and soda be contributing?

I would say mainly genetic. Idiot savants are examples of this. People who can't do much of anything for themselves can do one thing exceptionally well.

One man has the ability to tell what day of the week of any date, past or future.

One man could look at a building for a few minutes then go home and draw that building in exact detail but couldn't draw a person.

There are people that can look at a a series of numbers and add them instantly.

One man could remember every note of any music he heard but couldn't remember what people said.

In high school there was one special education student who could play any song he heard on the piano. They wanted him to play a number with the school orchestra but he couldn't play with other instruments. He would change tempo or key.

Nobody taught these people. They just do it. Some people have photographic memory which would make them seem much smarter. People can learn to do repetitive tasks but many can't figure something out that they never did before.

What you are good at as well as what you are not good at is programmed in the brain as the baby develops possibly by a signal from the dna or possibly by conditions in the womb.

No race baiting yet?

I am disappoint.

Here are two charts that kind of show the correlations to IQ. For the top chart, the parental education level I think is a good indicator of genetics and I suppose priorities. Since all the graphs track upward for greater parental education, you might conclude genetics plays a role. I suppose those that finish college often are more affluent so that is probably baked in as well.
The below chart comparing twin reared apart and together and correlations between parents and foster parents show how much genetics and environment can play. Genetics play a pretty strong role though.

Very stupid chart since "hispanic" is not a race and you perform an ancestry DNA between 10 hispanics the results will be totally different, instead if you do test 10 "Caucasians" their ancestry will have more correlation. Hispanic is not a race never was.

A lot of people confuse being knowledgeable with being intelligent.

Take it how you will but with the other stuff i presented there is a very strong correlation between parental iq and their children's independent of upbringing.

Those who feel that genetics doesn't have the major influence on intelligence probably don't feel that genetics has any bearing on skin color, eye color, height, the size of hands, feet, length of legs or any other physical characteristics.

In my own case I'm good in math and science and have good mechanical ability. I'm terrible at drawing things from an art standpoint but I do very well at mechanical drawing. I'm good at following directions. Not as good with abstract concepts.

Interesting to here man have you always had a "naturally" ability to pick on math and science ?

It isn't being used as a race, more as a culture.

 

[DanMMAleague]

Last I read, IQ can change by about 20 points between 12-16.

I'd like to think that's true because that's when I was taking school seriously.

It's mostly environmental. Genetic potential in meaningless without resources and tools.

I've always picked up math and science concepts very easily. I enjoyed the "story" problems that many people hate.

I'm bad at other languages too. I took Spanish but never learned much and have forgotten most of it.

As a mechanic, math and physics served me well. I've worked with people who don't understand leverage. I've known people who wanted to be mechanics who just couldn't do it. I attempted to show a surgeon how to change a tire. He was by no means stupid but he just couldn't figure out where to put the jack or how to operate it. Then which direction to turn the lug nuts. He took 3 off then tried to go the wrong way on the 4th.

People need to do what they're good at.

graphs are racist!

I agree with all you have said also i would like to add a lot of people struggle to find what they are "good" at in life

 

[mushishi]

It's a combination of nature and nurture. People will often generalise 2 smart parents having a smart child as genetic, but that fails to acknowledge that 2 smart parents are more likely to nurture their child.

They tend to have more tools in the genetic toolbox along with more nudging. Most important factor is determination.

 

[21 Savage]

Its 80% genetic btw.

[marioh]

mostly genetics, some environment, and a bit of luck (with how the brain develops over time from infancy to adulthood).

 

[Randy Trevor]

I like where this is going
