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

It challenges the common thought that girls with brothers grow up as tomboys Scientists have rubbished the theory that a child's personality is influenced by the gender of their siblings. 'Our findings refute the idea that growing up with brothers or sisters causes us to develop certain personality traits in the long term that are considered "typically female" or "typically male" in a society,' said study author Dr Julia Rohrer. The 'big five' personality traits are the best accepted and most commonly used model of personality in academic psychology In addition, the researchers looked at something called a typical female personality index, which was generated using five personality traits for which they observed 'systematic gender differences'. Statistical analysis of this data showed across national borders that the personality traits are not systematically related to sibling gender. Across all surveys, researchers found that the gender of the next younger sibling has no meaningful effects on women’s or men’s personality on an older sibling’s personality Economic studies have shown that in the US and Denmark, women with brothers earn less when employed.
