Are you the youngest, oldest, or a middle child? The way you answer that may have quite a bit to say about your level of success and intelligence.
A group of researchers from the University of Leipzig found an interesting comparison between birth order and intelligence after they “analyzed 5,200 Americans, 4,500 British people, and 10,500 Germans.”
The test consisted of questions pertaining to birth order, self-reported intelligence, and five big personality traits: agreeableness, consciousness, emotional stability, extroversion and imagination. Age gap was also taken into consideration.
They found that the oldest child consistently scored higher in intelligence and the score decreased slightly with each following child. Older children were also found to be more successful.
There are many theories as to why this may be true. One such theory is that the oldest child had access to more parental resources at a younger age. Another is that the oldest child acted as tutor to the other children.
Whatever the reason, scientists seem to agree that being the first born comes with a whole bunch of added benefits.
However, there are plenty of people who would not agree. For example, this study does not take into consideration families with only one child.
