Poster of Hanken's expert panel entitled: Navigating the Age of Misinformation: from Civic Awareness to Economic Consequences." In an era where misinformation spreads faster than ever, understanding its impact is crucial. In this Campfire Talk, we will bring together experts in civic literacy, economics, and political communication to explore the dual challenges misinformation poses to both democratic values and economic stability. Our experts will share their unique perspectives on how disinformation affects public trust, consumer behavior, and political discourse. Engage with us as we unpack strategies to build resilience and foster a more informed society in the face of digital disinformation. Guest speakers: Niklas Eklund, Professor in Political Sciences, Umeå University Anna Bertills, Communications Consultant & Strategic Analyst Carlos Diaz Ruiz, Assistant Professor, Hanken, Marketing Department Hanken students Moa Mattbäck and Jiri Wrangell will moderate this event.
