Senior child has a higher IQ, than younger

Research has proven that the first child is smarter than his brother or sister, reports Daily Mail. Scientists say that there is a high probability that the older child will have a higher IQ.

Staff at a Dutch university (Vrije University, Amsterdam) was observed for 650 children whose IQ was tested three times before they turned 18. According Dorret Bumsma (Dorret Boomsma), this result is characterized by the same for boys and girls. Highest IQ level was observed in no older brothers or sisters of children. In second place children who have one older brother or sister. And children who have two or more older siblings showed the lowest results in testing.

Why things are going that way until the end is not clear, however, perhaps the whole thing in the attention given by parents to their children: the firstborn gets the maximum amount of parental attention. However, the study also showed that, despite the fact that older children are the most clever, the younger are usually favorites of parents. Firstborn - prosperous life for the people, the average children - impulsive rebels. Junior - creative people, pets.
