A new study of monozygotic twins raised apart in South Korea and the United States provides unique insight into how genetic, cultural, and environmental factors influence human development. The new research has been published in the scientific journal Personality and Individual Differences.
“I have studied identical twins reared apart for many years. They pose a simple, yet elegant experiment for disentangling genetic and environmental influences on human traits. This case was unique in that the twins were raised in different countries,” said researcher Nancy L. Segal, a professor and director of the Twin Studies Center at California State University in Fullerton.

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.

Interesting, thank you.
LOL...funny that you post that product because every time I see it in the store I shake my head in disbelief. I still cannot figure out what they are trying to say. What a bunch of idiots in their marketing department.
Yet I still like that brand the best.
Methodology matters.
16 points difference for identical twins is BS.
And the results will never be repeated.
I read a ton of monozygotic twins raised apart studies in college. When there was a significant measurable difference, a little digging found the fly in the ointment. In some cases, the lower IQ of the two had a lower birth weight. Unequal access to nutrition in the womb. Others had a childhood disease that caused cognitive impairment. When raised apart, the less developed twin in a less nurturing childhood environment was typically able to "catch up" with 6 months of focused tutoring to even the odds.
“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.”
I think extended social/emotional trauma at a critical developmental stage is a more likely explanation than general environmental/culture/nurture effects.
“Women can pee standing up. Transphobe!”
Actually, women *can* pee standing up. It just takes more control to avoid a mess. And then there is “hovering”.
IQ isn't always intrinsically linked to parental IQ. Some brilliant, high IQ children are born to parents of average IQ. The reverse also occurs. Each child needs to be evaluated to really know what potential is present. Maximize the potential present. Don't try to make a silk purse of a sow's ear nor toss a diamond into a bucket of tar.
“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.”
What ever happened to the “born that way” vs. “choice” argument?
Clearly, it is a choice.
Hence the need to groom. Expands the options for Friday night.
Some MAY be born that way but it would be a small handful compared to the ones who are mentally unnatural and choose to be homosexual- a lot of them change back
And most of that money goes to the top-heavy administration in school districts. Just like any government entity, they start out with good intentions but then screw everything up. What’s that old parable about where the road to good intentions ends?????
The mind is just like muscles.
It needs to be exercised or it atrophies.
The USA school system has failed to deliver for the last 50 years.
I was lucky as my dad filled in the huge holes in my “public education”
Well, I didn’t grow up on a farm, but the life lessons I received during summer vacations were just as valuable as anything from similar lengths of time at school. Working, 2 summer stints with the Youth Conservation Corps (work, but quite an adventure, too), a 3 week family trip looping through the Western USA...
Don’t get me wrong, I studied hard and did very well in school. And through plenty of direct experience it is clear to me Asian kids generally ARE more successful academically than typical American kids. But, is that summer vacations, or is it our schools, and even more is it crucially family situations & input, not to mention many other social inputs? What would the comparison have been in the 1950’s or 60’s?
Interesting, but you can’t draw any conclusions from an N of 1 study. The twin who got lost could have experienced birth trauma that affected her IQ. The article also said she had contracted measles before she came to the US. High fever could also have impacted IQ. Or not. There are just too many variables to draw conclusions from this one case.
What is the matter with you?
Haven’t you ever seen a union “make work” project?
Come on out to FR HQ in Fresno and you can get an eyeful of Gavin Newsome’s “Rails To Nowhere” boondoggle.
Always makes me wonder what the laborers are thinking knowing that, for all their efforts, the ultimate result will be a monumental waste.
Yeah, so they can pay their bills.
How satisfying is work when it’s ONLY that?
It does support better gut health. Half of one's immune system is in the gut.
The US twin had measles at a very young age. Depending on how severe the case was that alone could explain the small difference in IQ
One set of twins is an anecdote, not a study.
There are no differences in intelligence.
All people are exactly equally intelligent.
Al Sharpton has exactly the same IQ as Albert Einstein had.
All methods and metrics yet devised for measuring intelligence are both unscientifical and/or culturally biased, and all claims to the contrary are rayciss.
