Nature versus nurture? Nurture!

Doesn't prove intelligence has no genetic component, but upbringing really does count.

[Eleutheria5]

So raise your kids in South Korea, where television programming and public school won’t make them stupider.

[billorites]

Kimchee makes you smart.

[Harmless Teddy Bear]

This has been known for some time.

It is just no one wanted to admit it.

There is a floor and ceiling probably but overall you can both increase and decrease IQ with the correct stimuli.

[marktwain]

It would be more persuasive if it wasn't a "one-of".

This is one case, involving 1 set of twins.

[newfreep]

No mention of where in the US & which school district the lost twin was raised

[Theoria]

Nothing surprising. On a slightly different note, Singapore, China, Korea etc do have world beating children in terms of test scores. However, the US usually does better at the finish line, later in life. Achievements early, are not an end point.

[Gay State Conservative]

East Asian culture (at least in Japan and the ROK) compels kids to study 10-12 hours a day,6 days a week and compels adults (at least men,don't know about women) to work 10-12 hours a day,6 days a week. It shouldn't be a surprise that they're smarter than we are.

[JerseyDvl]

Interesting study. I have twins though they are not identical.

I think it goes to show that our education system could use a total overhaul.

[Williams]

There is nothing surprising in this result we have completely dumbed down our education process and our population.

[moovova]

The kid raised in the US isn’t sure whether they/them are a boy or a girl?

[zeestephen]

A spread of 16 IQ points?

Sorry, very hard to believe that is all nurture.

USA GDP Per Capita - $76,000

South Korea GDP Per Capita - $46,000

North Korea GDP Per Capita - $1,800

I wonder what the IQ spread would be if the other twin was raised in North Korea?

[FarCenter]

Not only did the twins experience different cultures growing up, they also were raised in very different family environments. The twin who remained in South Korea was raised in a more supportive and cohesive family atmosphere. The twin who was adopted by the U.S. couple, in contrast, reported a stricter, more religiously-oriented environment that had higher levels of family conflict.

The researchers found “striking” differences in cognitive abilities. The twin raised in South Korea scored considerably higher on intelligence tests related to perceptual reasoning and processing speed, with an overall IQ difference of 16 points.

[9YearLurker]

Definitely counts, but not as much as nature.

[sphinx]

A sample set of one. Ok.

Since the results seem to be an indictment of U.S. television, popular culture, and public schools, I am willing to waive my usual caveats about small sample sizes and endorse these findings without reservation.

As a matter of public policy, the public schools are the place to begin because they are fully under government control.

The second key observation is that Tiger Moms are good if you want to raise smart, high achieving kids. Every family should have a Tiger Mom.

[Spok]

SJW’s closing the IQ gap in America have discovered that dumbing down is easier than smartening up. Politicians prefer it too.

[erlayman]

It would be interesting to know the parents IQ but does seem to conform to other evidence that low-income children, at least in the US, have fewer opportunities for their genetic potential to flourish. If I recall correctly the heritability of intelligence among poor children has been put somewhere around 25% vs 60-70 from wealthy families. For poor children in the South Korea as well (?), the family environment seems to matter quite a bit.

[bk1000]

Yes, but the US-raised kid now questions his gender and demands people use his preferred pronouns.

[pas]

Their education system vs our indoctrination system more like it.

[nikos1121]

If what she says is true, it has nothing to do with our culture vs their’s but the nurturing of the family vs disharmony....

But, I would wager... a thousand dollars that this researcher has found evidence that disputes a 100 years of twin studies around the globe

THAT FINDS NO EVIDENCE OF A GAY GENE.

IOWs all twin studies that I’m aware of shows that twins separated at birth, where one ends up gay, does not show a higher prevalence of the other twin being gay also.

[The Pack Knight]

The twins were born in 1974 in Seoul, South Korea. One of the twins became lost at age two after visiting a market with her grandmother. She was later taken to a hospital that was approximately 100 miles away from her family’s residence and diagnosed with the measles. Despite her family’s attempt to find her, she was placed into the foster system and ended up being adopted by a couple residing in the United States.

What a nightmare.
