Younger siblings are more likely to be better at sport.
The answer is true.
A study that looked at US national squads found in two out of three cases, when a pair of siblings both played the same sport professionally, the younger one was more successful.
Playing with an older sibling makes you more competitive.
True.
By playing with their elders, younger siblings learn at an accelerated rate.
The most famous women’s sports team in the world are a testament to the little sibling effect. USWNT legends Megan Rapinoe and Alex Morgan played with older siblings when they were growing up.
Older siblings are challenged more.
False.
Older siblings give young children someone to learn from and therefore challenge the younger sibling more.
“I’ve learnt a lot from watching Venus,” Serena said in 1998. Two or more people working together to learn a particular task is called dyadic learning.
To conclude, if you have a younger sibling they are probably better at sport than you.
