A new study shows that
Apparently, the eldest sibling is the smartest! According to the study, they get an IQ boost from having to teach their younger brothers and sisters how to do things. The study also suggests that this comes from the undivided attention the sibling receives while they're the only child.
A University of Edinburgh study shows first-born children have higher IQs and better thinking skills than their siblings. The study says that shows first-born kids get more mental stimulation than their brothers and sisters.
After examining 20,000 people, researchers from the University of Leipzig concluded that older siblings are smarter on average while younger siblings are healthier and are more likely to be gay (if they're men). It was the second-largest study to look at the effects of birth order.
There are some family effects on the IQ of children, accounting for up to a quarter of the variance. However, adoption studies show that by adulthood adoptive siblings aren't more similar in IQ than strangers, while adult full siblings show an IQ correlation of 0.24.
You've probably heard it before and brushed it off if you're a second, third or fourth+ child - but it's true: the eldest sibling is the smartest, according to research.
Now a new study, published in the Proceedings of the National Academy of Sciences and based on data from 20,000 individuals, concludes that birth order does matter when it comes to IQ – with the oldest having slightly higher IQ than their younger siblings.
Younger siblings generally have a lower IQ than their older brothers and sisters, according to three large national surveys from the US, UK, and Germany.
A new study shows that first-born children tend to be smarter than their siblings and second-born children are more likely to cause trouble. The University of Edinburgh study reported that the oldest child tends to have a higher IQ and thinking skills than their younger siblings.
According to Adler, the first born is more susceptible to depression because of high expectations of parents and suddenly losing the attention due to another sibling being born.
If you're the youngest or middle child in your family, get ready for some unwelcome news: Your eldest sibling is likely right when they brag about being the oldest and the wisest. And you can blame your parents for this.
Most notably, the study found that children born to older fathers are likely to have a higher I.Q. compared to those born to younger parents. Additionally, kids born to older parents exhibited a stronger focus in pursuing their interests and more self-confidence than those born to younger parents.
Birth order has been associated with IQ; first-born children tend to have higher IQ than their siblings (Kristensen & Bjerkedal, 2007) . ... Background: Specific learning disorders are common, with prevalence estimates of 3–15% among school children.
Researchers have found a correlation between risk-taking and being the last-born sibling.
Middle siblings may not wind up as the corporate chiefs or the comedians, but whatever they do, they're likely to do it more collegially and agreeably—and, as a result, more successfully—than other siblings. Your birth order may be immutable, but the talents and traits it leaves you with don't have to be.
A growing collection of studies suggests that being the youngest sibling may come along with some major health advantages. Researchers have found that the baby of the family is often slimmer and less prone to illness. As a result, younger siblings can expect to live longer than their older brothers and sisters.
While the youngest sibling is usually the funniest kid, mom and dad favor the youngest for a reason that might surprise you. According to a new study conducted by Brigham Young University's School of Family Life, the youngest sibling of the family tends to be mom and dad's favorite child because of perception.

In 2017, the 11-year-old London kid of Indian origin received the highest IQ score of 162. He is one of the world's smartest kids ever, scoring two points above Albert Einstein and Stephen Hawking.
American magazine columnist Marilyn Vos Savant has an IQ of 228, the highest ever recorded. She scored the highest IQ scores when she was 10 years old.
But genetics can explain the wide range of possible IQs too because so many different genes are involved in developing and running a brain. It is possible, for example, to inherit all the higher IQ genes from each parent and leave the lower IQ ones behind. Now the child will be brighter than the parent.
Middleborns are just as smart as their siblings.
But a study by the University of Illinois published earlier this year found that firstborns' IQs are only one point higher, on average, than their younger siblings — a fairly negligible difference.
Genetically, intelligence and IQ is polygenic meaning that many genes are involved in determining intelligence. As such, the correlation between parents and their children and among siblings can vary within a pretty decent range. A study from 1979 found that the correlation between sibling IQs was 0.49.
Teddy Hobbs might be the brainiest little boy in Britain. Still only 4 years old, Teddy could count to 100 before he turned 2. Now he can do it in seven different languages. "I just assumed, you know, every child has their own quirk.
Summary: For those who believe that birth order influences traits like personality and intelligence, a study of 377,000 high school students offers some good news: Yes, the study found, first-borns do have higher IQs and consistently different personality traits than those born later in the family chronology.
