Time To End The Argument – The Oldest Sibling Is The Smartest Person In Your Family

Whether you know it or not, birth or can you play a role in your intelligence? Various studies have shown that the elder has the most power when it comes to his brain. And while this might not always be the case, the trend does seem to hold up over time.

One thing scientist does agree on is that the love of parents pretty much is the same for all of their children, from the youngest to the oldest. Other factors affect the development of the child and contribute significantly to his intelligence and behavior.

Here is more on the interesting reasons why first-born children tend to be the smartest kids in the class.


Study show


A 2015 study published in the Journal of Human Resources found that first-timers tended to have higher IQ tests than younger siblings. Researchers from the University of Edinburgh and the University of Sydney analyzed data on a group of 5,000 children in the U.S. followed from pre-birth to 14 years old.



The results showed that firstborn children tended to have better results in younger cognitive assessments compared to younger siblings. In fact, the gap between the eldest and younger siblings only seemed to widen as they got older, becoming relatively constant upon reaching school age.


Birth Order and IQ

When doing the study, researchers also looked at the reasons behind such a big gap in intelligence, and their findings were relatively interesting. It seems that parents seem to try harder when they have their first child. Firstborn children seem to receive more mental stimulation and physical stimulation, in the form of breastfeeding.



In addition, first-time mothers are less likely to smoke or drink, not wanting to do any harm to their baby. On the other hand, as parents have more and more children, they seem to relax some of these restraints on their behavior or not pay as much attention to children past the first.

It’s not that they like these younger children, but simply that they were there and did it with the first child and feel that they can relax the rules a little with the following children.
This is also not the case with all parents, as some might be inclined to follow the same “rules” with all of their children.


Other Effects of Birth Order

In addition to intelligence, birth order can also affect a child’s personality. This usually materializes in the form of increased leadership skills, ambition, and a sense of responsibility than your younger siblings.Average brothers and sisters generally have better negotiation skills and are excellent conciliators. The youngest brothers and sisters are more charming, more creative and more manipulative.
