As reported in The First Post:
...having daughters makes parents more left-wing, as defined by voting for Labour or the Liberal Democrats. Conversely, bearing sons seems to direct parents to the right.The article goes on to speculate why:
The authors argue that having a daughter is likely to make a parent focus more on the position of women in society: they know their daughter will grow up to be mainly responsible for childcare and - very likely - suffer from pay discrimination.Interesting. Let's see...I've got two sons and one daughter, and I have two brothers and one sister.
Oswald and Powdthavee go on to argue that women are "inherently" collectivist, while men are more individualistic.
Yup...I guess they're right!
