    Social media has an unprecedented ability to capture attention and influence entire populations, leading to calls for greater accountability from companies to limit the potential harms these technologies can create. In a forthcoming paper, “Accountability Infrastructure for Recommendation Systems: Methods for Identifying and Mitigating Structural Harms Created by System Architecture,” Nathaniel Lubin and collaborators present a framework for tech companies to move beyond content moderation and create enduring systemic change within their platforms to address concerns around social media.

    Artist Ben Grosser creates interactive experiences, machines, and systems that examine the cultural, social, and political effects of software. Recent exhibition venues include Somerset House in London, Centre Pompidou in Paris, SXSW in Austin, Museum of Modern Art in Moscow, Museu das Comunicações in Lisbon, Museum Kesselhaus in Berlin, Science Gallery in Dublin, Japan Media Arts Festival in Tokyo, and the Digital Arts Festival in Athens. His works have been featured in The New Yorker, Wired, The Atlantic, The Washington Post, The Los Angeles Times, PBS, Fast Company, BBC, The Telegraph, Le Monde, Corriere della Sera, Der Spiegel, El País, and Folha. The Guardian (UK), writing about his recent film ORDER OF MAGNITUDE, said “there will be few more telling artworks [from] the first decades of this century … a mesmerising monologue, the story of our times.” Speaking about his social media-focused projects, RTÉ (Ireland) described Grosser as an “antipreneur.” Slate referred to his work as “creative civil disobedience in the digital age.” Grosser’s artworks are regularly cited in books investigating the cultural effects of technology, including The Age of Surveillance Capitalism, The Metainterface, and Investigative Aesthetics, as well as volumes centered on computational art practices such as Electronic Literature, The New Aesthetic and Art, and Digital Art. Grosser is an associate professor of new media in the School of Art + Design and co-founder of the Critical Technology Studies Lab at the National Center for Supercomputing Applications, both at the University of Illinois at Urbana-Champaign, USA.

    Motivated by the insight that social media platforms are designed to keep users on an endless quest for more—more updates, more likes, more content—Ben Grosser’s Minus asks what users would do with less. Minus allotts users just 100 posts–for life, aiming to create an online space that mimics the finite time and resources we have in the physical world. Since launching in 2021, Minus has gained thousands of users and hosted tens of thousands of posts and comments.  Ben’s time as an RSM Assembly Fellow was devoted to in-depth analysis of Minus as a platform, which teased out how the affordances of constrained social media platforms encourage different sorts of interactions and conversations among users.

    Assembly Fellowship Project:

    The digital age has created a new predicament for parents: when should a child be introduced to smartphones, and how can parents ensure their child’s relationship with the device is a healthy one? Tempok, developed by social entrepreneur Javier Agüera, is a framework that turns the gifting of a child’s first smartphone into a rite-of-passage ritual that encourages families to create positive habits and boundaries by focusing on trust and autonomy.  Javi conducted interviews with dozens of parents and families, synthesized existing research, and developed Tempok’s offerings and roadmap during his time as an RSM Assembly Fellow.  Tempok will launch as a public benefit corporation in late 2023.

    It’s hard to talk about hard things online, and the structure and incentives of social media platforms aren’t making these critical discussions any easier. Kathryn Hymes’ project uses principles of game design, in service of conversation design, in service of platform design—informed by principles of close listening, equal participation, and active communication—to develop a framework meant to encourage better conversations online. Kathryn’s time as an RSM Assembly Fellow was spent designing, playtesting, and refining a game pilot which incorporated these elements and aims.

    Journalists and human rights defenders–particularly women and people from marginalized groups–experience online abuse at alarming rates. Building off of a recent workshop and closed-door discussions with industry experts, Elodie Vialle worked to address this issue with the Escalation Channel 2.0, a third-party system that allows professionals facing severe online abuse to raise their case within social media platforms while simultaneously accessing hands-on, trauma-informed support. This culminated in a long-form working session with Meta, civil society organizations, and academic institutions, focused on developing discrete interventions and updates to Meta’s existing journalism resources.

    Hate speech and extremist language online are often shrouded in ever-shifting context and double meaning that are nearly impossible for moderators to effectively track. Relying on Kesa White’s expertise as a researcher of online extremism and a database of masked terms that she constructed, D3COD3 is a browser extension that identifies this intentionally coded language, giving both content moderators and general users insight into the potential threats they present.

    If we’re going to reboot social media, Sahar Massachi believes we’ll need access to a critical resource: integrity expertise. Integrity professionals are tech workers with experience addressing and mitigating harms to people and societies within social Internet platforms. The Integrity Institute, co-founded by Sahar in 2021, brings these individuals together as part of an organization that aims to create a social internet where people, societies, and democracies thrive.  As both a think-and-do tank and a community of practice, the Institute Integrity advises policymakers, companies, and academics, while developing best practices for the profession at large.  Sahar’s time as an RSM Assembly Fellow was spent building out the Integrity Institute’s operations and expanding its community during a key period for the trust and safety space.
