Science Says the First Born Child Is the Most Intelligent


Science Says the First Born Child Is the Most Intelligent

Your oldest child really has the potential to become the next Einstein!


A new study carried out by Leipzig University suggests that the IQ of first-borns increases because they have to teach their younger siblings how things work. The fact that first-borns have their parents' attention all to themselves also boosts their IQ.
It is said that the variations in intelligence are a result of how a child is raised and nurtured, not of biology.
The study evaluates a 1.5 IQ drop per sibling. In families with two children, however, the first-born isn't necessarily the most intelligent since they only have a 60% chance of having a higher IQ. In this equation, there is still a good chance that the younger sibling will surpass them later on life.
Apart from boosted intelligence, first-born children also show a heightened perception of their brain capabilities. The data for this study was accumulated from personality and IQ tests from three different national studies, one of which was carried out in the UK and involved more than 20,000 participants.
"One theory is that following children "dilute" the resources of their parents.", Dr. Julia Rohrer told the Daily Mail.
“While the firstborn gets full parental attention, at least for some months or years, late-borns will have to share from the beginning.”
“Another possible factor is described by the tutoring hypothesis: A firstborn can “tutor” their younger siblings, explaining to them how the world works and so on.”
“Teaching other people has high cognitive demands – the children need to recall their own knowledge, structure it and think of a good way to explain it to younger siblings, which could provide a boost to intelligence for some firstborns.”

Women Absorb And Retain DNA From Every Man They Have Sex With

Women Absorb And Retain DNA From Every Man They Have Sex With Women retain and carry living DNA from every man with whom they have sexual intercourse, according to a new study by the University of Seattle and the Fred Hutchinson Cancer Research Center. The  study , which discovered the startling information by accident, was originally trying to determine if women who have been pregnant with a son might be more predisposed to certain neurological diseases that occur more frequently in males. But as the scientists picked apart the female brain, the study began to veer wildly off course. As it turns out, the female brain is even more mysterious than we previously thought. The study found that female brains often harbor “ male microchimerism “, or in other words, the presence of male DNA that originated from another individual, and are genetically distinct from the cells that make up the rest of the woman. According to the study: “ 63%...

This Woman’s Runny Nose Was Actually Spinal Fluid 52-year-old Kendra Jackson from Omaha, Nebraska, had been suffering from a runny nose for quite some time. Her runny nose occurred two and a half years after she got into a serious car accident, but doctors didn’t see any correlation – they just put it down to allergies, however Jackson knew it was more than just that. Her runny nose started to worsen in 2015, “ When it didn’t go away, I kept going back and forth to the doctors, and they prescribed every kind of medicine you can think of, and my nose just kept on running ,” she said. After having a runny nose for more than two years, she went to see physicians at the University of Nebraska Medical Center earlier this year, and learned the real reason behind it. The physicians discovered that her nasal discharge was actually cerebrospinal fluid (CSF), leaking from a small hole in her skull that occurred when she had the crash.
