Facebook Chief Operating Officer Sheryl Sandberg was on “The Kelly File” tonight to discuss the latest edition of her book, “Lean In: For Graduates.”

“The world has been run by men exclusively almost for far too long and I think we’d get to better decisions if women’s voices were equally heard at those tables,” she told Megyn Kelly, adding that she is often the only woman in the room.

Sandberg said that women come into the workforce and are making less than men out of college. Then, that wage gap continues. She said that women need to learn to negotiate for themselves and to do it differently than men. For example, she suggests using more communal language and explaining why you’re advocating for a higher salary.

“When men are successful and powerful, they get more liked as they get more successful and more powerful, but when women get successful and powerful, they’re less liked, so men don’t have that trade-off,” she said. Sandberg also touched on the “Ban Bossy” campaign, which drew criticism from some.

She said that by middle school, more boys want to lead than girls. When you ask why girls don’t want to lead, they say they want to be liked and don’t want to be seen as bossy.

“What 'Ban Bossy' was about was making all of us aware that we start discouraging girls early,” she said.

“We want every woman to believe she can reach for every dream,” the Facebook COO told Kelly.
