Ahead of the U.S. 2020 presidential election, the Carnegie Endowment for International Peace convened more than 100 experts from three dozen organizations inside and outside Silicon Valley in private meetings to help address the challenges that synthetic and manipulated media pose for industry, government, and society more broadly. Among other things, the meetings developed a common understanding of the potential for synthetic and manipulated media circulated on technology platforms to disrupt the upcoming presidential election, generated definitions of “inappropriate” election-related synthetic and manipulated media that have informed platform content moderation policies, and equipped platforms with playbooks of effective and ethical responses to synthetic and manipulated media. Carnegie commissioned four short papers on the legal, ethical, and efficacy dimensions of election-related synthetic and manipulated media to brief meeting participants, and now the broader public, on the state-of-play.
