How many partners you’ve had matters – but so does when you had them. A global study reveals people judge long-term partners more kindly if their sexual pace has slowed, challenging the idea of a universal sexual double standard.

A new study has cast doubt on the idea that women are biologically wired to wake more to a crying baby than men. It suggests that the significant disparity in nighttime care is due to social, rather than biological, factors.
