Last night Stephen Colbert had two awesome ladies on his show: Katty Kay and Claire Shipman, co-authors of "The Confidence Code." The book attempts to decode why it is that women are less confident than men -- especially in the workplace.
"Why don't you just grow a pair?" Colbert asks. "You know, that's my book: 'Growing A Pair: Womanhood the Colbert Way.'"
Confidence, the authors found, does have something to do with genetics. A whole host of biological factors can play into why some women are not confident, the authors explain.
"I think if women could take more action, take more risks, be prepared to fail, not be so perfect all the time," Kay explains. "We're obsessed with being perfect -- that could hold us back from being confident."
With Colbert in character, the interview has a few cringe-worthy moments -- like when he asked if the confidence gap had anything to do with the "thigh gap."
"We're not going there!" Kay replies. "No, we're not going there."
They do, however, discuss some important ways to build confidence, including playing sports and letting girls fail and take risks. Watch the segment below:
