From Slate: Girls don’t start out more anxious than boys, but they usually end up that way.
When it comes to our preconceived notions about women and anxiety, women are unfairly being dragged through the mud. While women are indeed more fretful than men on average right now, this difference is mostly the result of a cultural setup—one in which major social and parenting biases lead to girls becoming needlessly nervous adults. In reality, the idea that women are “naturally” twice as anxious as men is nothing more than a pernicious illusion.
