Amidst proliferation of online negativity and harmful content such as fake news and harassment on social media, this panel will be an active discussion of the potential roles of various actors in sociotechnical systems in curating, moderating, and studying content. Should companies intervene? Why or why not, and if so, to what extent? What role do academics play in this process and how does it affect research processes? Our multidisciplinary panelists represent humanities, computer science, law, and media psychology. They will share perspectives based on their own research and interact with the audience to discuss varied perspectives around these central questions. A primary goal is to think about how, moving forward, these issues affect HCI research.
