Lee Rainie, director of internet and technology research at Pew Research Center, delivered this keynote speech at the New Media and Society conference in Toronto on July 29, 2017. He discussed eight changes in the information ecosystem that are making this a particularly challenging moment for social media proponents and those who advocate for the internet and how citizens are trying to navigate the challenging world of “fake news” and “truthiness” on social media. He examined the impact of these challenges on the way that people’s trust in information sources is shifting.
