A new study shows that
A 2016 study published in the Journal of Human Resources has said that firstborns are academically more intellectual and successful than other siblings because parents tend to be more invested in them.
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.
Middle children are often the most successful sibling in their families, according to research.
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.
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.
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.
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.
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.
Researchers have found a correlation between risk-taking and being the last-born sibling.
So while your parents may love and care for all their children equally, firstborns tend to get the most mental stimulation, since they receive the undivided attention of both parents and all that first-time anxiety.
No matter the situation, we're used to things not going our way. Therefore, the middle child is a resilient beast. We don't crumble under pressure (like the baby of the family), nor are we prone to getting a big head (like our older siblings). We're just strong and grounded AF.
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.
First, it's possible first-borns are superior in some biological sense. They are born of younger wombs or to stronger healthier mothers, whose bodies are not yet ravaged by the demands of caring for other children.
Black points to research she and her colleagues have conducted that found that firstborns tend to be smarter, richer, and all-around more successful than their younger siblings. That's possibly because parents may be less invested in parenting with younger kids.
Eldest daughter syndrome is the burden felt by oldest daughters because they're given too many adult responsibilities in their family before they're ready. Eldest daughter syndrome can make women feel overburdened, stressed out, and constantly responsible for others.
Many previous studies looked into this relationship. There is evidence that the first born children experience more stress than their younger siblings. Weiss (1970), conducted a study to assess the relation between birth order and anxiety.
What is a golden child? "When people use the term 'golden child' or 'golden child syndrome,' they are referring to a child who has been deemed by their family—most often the parents—to be exceptional in one way or another, but without a foundation for the attributed exceptionalism," explains Smith.
The survey concluded that parents tend to favour their youngest child over the elder.
Younger siblings may be especially vulnerable to trauma because they are in an earlier developmental stage than the rest of the family. While older siblings and parents will be much more equipped to cope with the stress, the youngest child may feel left behind or not understand how to handle their emotions.
Researchers at the University of Illinois used a sample of 377,000 schoolchildren and found there were differences in personality traits, with the eldest sibling tending to be more extroverted, agreeable and conscientious.
You're also more likely to develop depression if you are between ages 45 and 64, nonwhite, or divorced, and if you never graduated high school, can't work or are unemployed, and don't have health insurance.
