International concern for the human rights of Afghan women has spiked since the Taliban consolidated power in Afghanistan in fall 2021. Yet little is known about how to effectively advocate for women’s human rights under this new context. We present findings from a random sample of all adult Afghan internet users’ attitudes toward peace, security, gender, and human rights and find significant support for women’s human rights as a national priority within Afghanistan, even when controlling for other priorities and even among many men and women aligned with the Taliban. Given that men now have much more political power in Afghan society to protect women’s rights, we paid particular attention to men’s attitudes toward women’s human rights. Our evidence from an embedded survey experiment, building on earlier literature from other countries, demonstrates that fathers of eldest daughters are particularly likely to favor prioritizing women’s rights when primed to think about the gender of their eldest children. Thus, the human rights and humanitarian community should spend more time and attention engaging with this demographic, and specifically creating marketing and advocacy strategies that encourage men to think about or act on behalf of their eldest daughters.
