Study shows first-born children might be smarter than their siblings

By: Nick Cardona, Veuer

According to a new joint study from the University of Edinburgh, the Analysis Group and the University of Sydney, first-born children may have better thinking skills than their siblings. The study found that first-born kids have higher IQs than their younger brothers and sisters.

Researchers tested 5,000 kids, monitoring them from pre-birth to 14 years old. Every two years, they were given tests on reading, vocabulary and mating letters.

One researcher said changes in parental behavior may explain the differences in education between siblings. The study showed that parents were less likely to do mentally stimulating activities with their younger children.

Perhaps it is true that the older sibling is smarter and the younger sibling really does get the hand-me-downs.
