I don't follow. I was explaining why the "hiring only the best" strategy perpetuates a gender imbalance. If there is an 80:20 gender ratio in the industry, and assuming an equal skill distribution, then there will be about 4 times as many men as women in the "hiring only the best" work force. It's not hard to imagine that this could dissuade some young women from choosing this industry, regardless of their aptitude for it. As a result, we have fewer high quality candidates in the industry as a whole. One way to change this is to correct the imbalance in industry, giving young women a more welcoming environment, role models, etc. However, this actively requires a different hiring strategy than "only the best." As I said, this gets into a "tragedy of the commons" situation, which can only be resolved through collective action, whether voluntarily within the industry like hiring quotas and outreach to women or enforced by the government through affirmative action-style laws.
