In the latest issue of the Journal of Politics, a new paper claims that they’ve found a causal relationship between boys growing up with sisters and their eventual political leanings.
According to the study, “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 analysis is based on survey results of more than 3,000 respondents that were conducted in 2006 and 2008 as part of an ongoing longitudinal study.
For young men who grew up with sisters but no brothers in their household, the chances of them identifying with the Republican Party are 8.3% greater than boys who grow up with only brothers.
Birth order and age difference were also explored as variables in the study. The research concludes that sisters are more likely than brothers to wash dishes, clean and do laundry, and that this exposure to gender stereotyping at an early age translates into more socially conservative views later in life.
