The rapid diffusion of online misinformation poses extensive societal consequences, necessitating urgent action. This symposium unites scientists dedicated to combating misinformation, providing a platform to share insights, methodologies, and findings. With a focus on online social media, the symposium encompasses four distinct perspectives: First, shedding light on partisan disagreements in content removal. Second, examining the impact of aligning message framing with moral values. Third, proposing an early warning detection system using text analysis and psycho-linguistic characteristics, and fourth, investigating how well fact-checking works in the face of emotional claims. Through interdisciplinary collaboration across psychology, communication, computer science, and computational social sciences, the symposium fosters comprehensive exploration of misinformation sharing. By fostering unique insights and fruitful discussions, this symposium facilitates solutions to combat the rapid spread of online misinformation in our digital era. Finally, we aim to advance the status of academic research as well as propose actionable insights to make today’s social media a better place.
