In this talk Mevan will be taking a deep dive into the world of fact checks, and fact checking. Together we'll be exploring the real-world context: How many fact checkers are out there? How are they organised? How do they fit into the information ecosystem? We'll be doing a deep dive into how fact checking actually works on the ground: Is it an effective intervention? Does it change minds? How are fact checks actually made? And we'll be ending on what the challenges are in the modern day with respect to specific examples of mis/disinformation, GenAI and global data infrastructure. Together we'll explore the opportunities and limitations, and how these will affect the future of information credibility around the world.
