Via Tyler Cowen at Marginal Revolution, news of an interesting new study that concludes “This paper provides evidence that daughters make people more left wing. Having sons, by contrast, makes them more right wing.”

Only performed, apparently, on British and German data.  (The full academic papers are available here.) It'll just be a matter of weeks until somebody tries this with American data.

But I'll report that in the Newmark household there are two data points against the weak version of the hypothesis and one against even the strong--based on "switchers"--version.

And I don't believe it, but I don't have a ready alternative explanation for the data.
