The eldest child of a family develops a higher IQ than that of his/her little brothers and sisters!

Being the first child in a family has its advantages, in fact, a Norwegian study analyzed the IQ of 250,000 young people between 18 and 19 years showing that the eldest child of a family tends to develop a higher IQ than that of his brothers and sisters. This is due to the position as the first-born in the family.

« The study shows that the relationship between birth order and IQ depends on social rank in the family and not simply the birth order », explained Professor Kristensen, the author of the study.
