Right, but certain careers have figured out that women are, on average, better at the socialization game and thus, broadly speaking, a better fit for the job. Ain't nobody "diversity" hiring on the oil rigs or other jobs where the physical act is more important than interpersonal interaction.

However, it is difficult to measure those positive traits for what they are, so employers are selecting based on gender hoping for positive correlation. But that's illegal, so "diversity" hiring was created as a scapegoat to help avoid legal fire.
