Your skills speak louder then your gender

Edit: Your skills should speak louder than your gender

The same applies to height, weight, race, etc. These things shouldn't matter, but they do. Even if only subconsciously.

"In the U.S. population, about 14.5 percent of all men are six feet or over. Among CEOs of Fortune 500 companies, that number is 58 percent. Even more strikingly, in the general American population, 3.9 percent of adult men are 6’2″ or taller. Among my CEO sample, 30 percent were 6’2″ or taller."

"Is this a deliberate prejudice? Of course not. No one ever says, dismissively, of a potential CEO candidate that ‘he’s too short.’ This is quite clearly the kind of unconscious prejudice that the IAT picks up. Most of us, in ways that we are not entirely aware of, automatically associate leadership ability with imposing physical stature. We have a sense, in our minds, of what a leader is supposed to look like, and that stereotype is so powerful that when someone fits it, we simply become blind to other considerations. And this isn’t confined to the corporate suite. Not long ago, researchers went back and analyzed the data from four large research studies, that had followed thousands of people from birth to adulthood, and calculated that when corrected for variables like age and gender and weight, an inch of height is worth $789 a year in salary. That means that a person who is six feet tall, but who is otherwise identical to someone who is five foot five, will make on average $5,525 more per year."
