A new study reveals how Russian trolls manipulated our Twitter conversations

Over the weekend, Twitter told 677,775 people via email that they interacted with Russian propaganda during the 2016 presidential election. But according to Kate Starbird, an assistant professor at the University of Washington, that's far from enough.

In a Twitter thread on Saturday, Starbird shared her recent research into social networks and the "echo chambers" they create. Her team successfully identified that polarized tweets are one way people, including Russian trolls, can effectively manipulate conversations.
