I decided to take a few days to get together my response for this because in my opinion, well, you're all wrong or looking at this from the wrong angle.
The reason they do this isn't to get more women on boards now for any immediate reason even if that's how they sell it to you. The reason they do this is to start shifting societal norms. Corporations do this. I'm on a committee at work and they asked us about changing a bonus system, some people disagreed since it wouldn't benefit them while some people agreed since it would benefit them. I found out just how much of a natural born corporate shill I am that day by chiming in that it didn't matter what anybody thought, it mattered that in a year or two when all the staff were different anyways this would be the new normal and how would it benefit us then ? What kind of staff would we be attracting and would this effect our ability to retain the best staff in the long term ?
So, current opinions aside, what does this do in a year or in five years ? When everybody's moved on to talking about something else ? Keep in mind that Trudeau's gender neutral cabinet is old news, I actually straight up forgot about it. What did it do though ? It changed who we saw in power and that's important because it gets us more comfortable with the idea. Let's look at nurses, generally elderly patient don't like male nurses because it's weird for them. They aren't used to it. So we provide incentive to going into the profession or hiring male staff. It achieves basically nothing in the short term beyond some numbers. In the long term though people growing up now see male nurses more commonly and aren't as weird about it. We now have a larger pool of people who are likely to pick the profession and considering our aging population and nursing shortage that's not such a bad thing. Representation is generally what people are trying to change with these things, encouraging a wider variety of people to aim high has benefits across the country. You want to lower teen pregnancy and thereby the number of people relying on the welfare system ? Want to lower the number of people who fall through the cracks ? You've got to give them something to aim for. They don't even have to become a CEO, all they have to do is not get knocked up or get hooked on drugs before they're able to take care of themselves. In this case representation matters.
I strongly recommend any book by Bruce Hood, one of my favourites is called The Self Illusion which argues the self as we know it is likely entirely built of our experiences in the world. One study cited looked at how gender plays a part in how we interact with babies. The same baby was dressed in either blue or pink and introduced as either Nathan or Sarah. When introduced to the same baby as a girl the adults talked about how beautiful she was and when introduced to the baby as a boy they commented on what career they might have. This study was done in 1986, the women who young girls now look up to were raised in this type of environment. So the question isn't do women simply prefer different professions, it's not even have we socially influenced women to prefer different professions ( we know we have ), it is can we use this to our benefit. Corporations don't care about you, and neither does the government. Corporations care about the health of said corporation and the government cares about the health of the place they are governing. Some succeed and some fail, this is how one is attempting to succeed in the long run.
