Much of the conversation on the radicalization of young people by extremist organizations has focused on Islamist groups like ISIS or al-Qaeda. But white supremacists are also using those tactics to recruit young, disaffected people to their ranks—and might be even better at it.

Alice Marwick of the Data & Society Research Institute in New York City studies how white supremacists and far-right groups use social media to spread their beliefs. She joins WNYC's Richard Hake to discuss these tactics and why they work.
