The area of "how we talk" poses the "double bind" trap for women. If women speak "Fran", they may be seen as lacking confidence, being unassertive, and not being "leadership material." (Or she may not be heard at all.) That's because the definition of leadership is associated with being confident and assertive.
I have been around confident, amazing women my whole life -- from school, to work, to the mothers of my children's friends, there are confident women all around me. And I, myself, have had a successful career. With that said, when I think deeply about it, I do see examples fairly frequently that can fall under the theme of the confidence gap.
