Girls with brothers are no more likely to grow up as 'tomboys', study finds

Scientists have rubbished the theory that a child's personality is influenced by the gender of their siblings. Many think that children who grow up around multiple siblings of the opposite sex are influenced by them in terms of personality well into adulthood. For example, girls with brothers are seen as likely to become'tomboys', while boys with sisters are seen as likely to become'girlish', according to common belief. But a new study suggests this way of thinking is a misconception – and that sibling gender'does not systematically affect personality'. Our personality as adults is not determined by whether we grow up with sisters or brothers, the new study claims.
