If we only teach certain stories from history — and if we leave out so many female pioneers – school-aged girls will only see themselves pursuing certain paths. They won’t have the examples needed to imagine other outcomes, for themselves or their female friends. It’s part of the reason why women represent 51 percent of the world population, but a mere one out of seven of our engineers. It’s why we continue to see female policymakers and advocates overshadowed by male counterparts. And why we risk limiting the insights and innovations today’s schoolgirls can bring to science, journalism, the military, and more.
