On role models, electing women makes more women interested in politics. That is straight up. We can find evidence for that throughout all OECD democracies. There's very clear evidence from Sweden, starting in the 1970s, that when a party started implementing seriously a voluntary party quota to get women elected, in subsequent elections women have been more interested in politics.
One of the things I want to push back against is that women just need more resources. I think women do need resources. Canadian women need child care. We need education. We need to be in these high-status occupations and things like this, but moving women into these positions doesn't actually decrease these engagement gaps that make women more interested in politics. What makes women more interested in politics is seeing more women do politics.
