The role of women in the workplace has been slowly evolving over the past 60 years. However, in the U.S. and around the globe, much progress remains incomplete in the quest toward equal opportunity and the eradication of sexism in our work, politics and culture. Consider a few glaring examples: Women still earn less than men for the same work, even the U.S. Women's Soccer Team made national headlines this year in their efforts to receive equal pay to their male counterparts. And in politics, more than half of men say they are still "uncomfortable" with the idea of being governed by an elected, female leader.

In some ways, it's a fascinating psychological question: Do men hold onto antiquated and outright sexist ideas because our cultural institutions lack true equality, or do those powerfully lingering sexist ideas maintain the gap in gender inequality at home and abroad?

Regardless of who or what is to blame, these antiquated ideas remain powerfully entrenched.
