First born children have an IQ boost a new study has revealed.
The study, carried out by scientists at The Leipzig University (Germany), revealed that this is due to the eldest child having the parents’ undivided attention. They found out there was a 1.5 drop in IQ (Intelligent Quotient) per sibling.
Older children also showed an increased perception of their brain power as well as demonstrating a heightened intelligence.
The study’s data came from IQ and personality tests from three national studies, one from the UK, involving more than 20,000 people all together.
