According to a new study by The Leipzig University if you have a younger brother or sister, they should be a bit more derpy then you,
This is because the study suggests first-born children get an IQ boost, which is thought to come from having to teach their younger brothers and sisters.
The scientists behind the study also suggest that having undivided attention benefits the IQ, which in turn will also benefit the first child. For example, Prince Harry is unlikely to have a higher IQ than his brother, but Harry can go party with girls while William has to pretend to be excited about being king one day.
This however, also means that an only child should be super smart, but I have neither a brother or sister, and I barely got my maths GCSE. Probably because I was too busy talking to girls to be honest. JK, I was a virgin until I was 19.
Don’t worry though, if you are the youngest sibling, the difference in IQ is estimated at around 1.5 points.
If you’re part of a two child family, the elder child will have a six in 10 chance of having a higher IQ.
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.
