Boys with sisters are more likely to be 'sexist and Republican because they are never made to cook or clean' research claims



Having only female siblings makes boys more likely be Republicans as adults, new research claims.

Professors from Loyola Marymount University and Stanford University analyzed surveys completed by more than 3,000 individuals when they were aged ten plus in 1987 and again a decade later.

They concluded that men in their 20s and 30s who grew up with sisters and no brothers were 8.3per cent more likely to identify as Republican because they developed 'more traditional views of gender'.

Political leanings: Having only female siblings makes boys more likely be Republicans as adults, new research claims - apparently this is because they develop 'more traditional views of gender'

This trend did not apply to young women from all-girl families.

It is not clear if mens' leaning towards the GOP carries on into later life and there's a possibility that the so-called 'sister effect' may diminish over time.

Andrew Healy and Neil Malhotra who led the study also said men surrounded by women growing up were less likely to get involved in stereotypical female tasks such as cooking and cleaning.

Whereas for a family with only boys,these household tasks are more likely to be shared among the children, therefore emphasis is not placed on gender-divided roles.



Men with sisters only were also 3.8per cent more likely to agree with the statement that 'a woman's place is in the home.'



Mr Healy and Mr Malhotra concluded: 'Having sisters makes males more politically conservative in terms of their gender role attitudes and their partisanship.

'Particularly for gender role attitudes, we find that these political socialization effects persist until respondents are well into adulthood.'



The findings were published in the latest issue of the Journal of Politics,
