There absolutely is an easy, obvious way to fix it. It's just something that gives men the screaming meemies. Quotas. Don't give me guff about "the best person for the job". You've been picking the best man for the job.
Women are picking the best man for the job as well. "The gender of the faculty participants did not affect responses, such that female and male faculty were equally likely to exhibit bias against the female student." http://www.pnas.org/content/early/2012/09/14/1211286109#aff-...
Quotas really are quite a multifaceted fix.
- Directly and immediately drive up numbers.
- Create a demand for women that pulls the supply.
- Create a supply of women leaders with experience and skills.
- And create somewhere for them to go, so they don't get discouraged and quit.
- Change people's mental image of working with/for women from abstract and theoretical to specific and personal. Overwrite their stereotypes with actual experience. This goes for both men and women.
