One of the most well-established patterns in measuring public opinion is that every generation tends to move as one in terms of its politics and general ideology. Its members share the same formative experiences, reach life’s big milestones at the same time and intermingle in the same spaces. So how should we make sense of reports that Gen Z is hyper-progressive on certain issues, but surprisingly conservative on others?

The answer, in the words of Alice Evans, a visiting fellow at Stanford University and one of the leading researchers on the topic, is that today’s under-thirties are undergoing a great gender divergence, with young women in the former camp and young men the latter. Gen Z is two generations, not one.

In countries on every continent, an ideological gap has opened up between young men and women. Tens of millions of people who occupy the same cities, workplaces, classrooms and even homes no longer see eye-to-eye.
