What is the role of social media in our politics today? To discuss, we are joined by Renée DiResta, a leading analyst of the internet and its effects on politics and society. As DiResta explains, social media platforms today are significant sources of political power that are fundamentally different from traditional media like newspapers, radio, and television. Social media makes users active participants in the consumption of information and algorithms have reinforced the polarization in our politics: “Algorithms key off of things that you like, things that people who are like you like. And then when that happens, you are put into these buckets, where you’re going to see more of a certain type of thing, so those identities are reinforced.” DiResta considers the ways in which Elon Musk has changed X (formerly Twitter), the power of controlling a social media platform, and the importance of this new phenomenon in politics at home and abroad. DiResta also shares her perspective on positive and negative effects of social media, from the highlighting of new perspectives to the proliferation of conspiracy theories.
