JB heps us to an interesting survey from across the pond. Fathers of daughters become more left-wing, academics claim:
Economists claim to have found a correlation between the number of daughters and sons in a household and their father's political views.
By analysing data in the British Household Panel Survey, they found that 67 per cent of parents with three sons and no daughters voted for Labour or the Liberal Democrats.
Professor Andrew Oswald, from Warwick University, and Dr Nattavudh Powdthavee, of York University, wrote in an unpublished article that has been submitted to an economics journal: "This paper provides evidence that daughters make people more Left-wing, while having sons, by contrast, makes them more Right-wing."
Professor Oswald said that having daughters made men "gradually shift their political stance and become more sympathetic to the 'female' desire for a ... larger amount for the public good".
"They become more Left-wing. Similarly, a mother with sons becomes sympathetic to the 'male' case for lower taxes and a smaller supply of public goods," he said.
Whew. A lot to unload here and no time to do it. For now, let me just note that I have three sons and JB has two. And you thought we were right wing before...
UPDATE: I imagine that one exception to this rule would be the father's stringent belief in the right to keep and bear arms, especially in the presence of hormonal teenage boys.
