Luna and Helin discuss how social media fragments our society by polarizing politics. In particular, they explain the echo chamber effect and filter bubbles resulting from algorithms and how these further radicalize opinions. Sensationalist journalism exacerbates the spread of misinformation and extreme political views, while politicians and influencers simultaneously manipulate social media to spread their ideology. Towards the end of their talk, Luna and Helin will offer tactics of critical analysis to protect our society from misinformation and political polarization. Luna Fast and Helin Turhan are both seniors at the Berlin Cosmopolitan School. Growing up in an international environment, they developed a multicultural perspective that sparked their interest in cultural, social, and political issues. Their passion for politics led them to participate in Model United Nations (MUN), where they honed their public speaking skills and deepened their understanding of international relations. After graduation, Helin plans to study business at Hult International Business School in London, while Luna will begin a voluntary social year (FSJ), volunteering at food banks in New York City and supporting a community center on the coast of Ecuador.This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
