Title: Social Media Impact on Online News Consumption: Echo Chambers, Information Diversity, and Ideological Polarization

February 11th, 2020

Description: There is concern that social media creates echo chambers in which homophily in online social networks and filtering by content selection algorithms combine to limit exposure to diverse viewpoints, thereby encouraging individuals to adopt more extreme ideological positions. Yet, empirical evidence regarding the role of social media in the formation of echo chambers is inconclusive. We demonstrate that this may be due in large part to imprecision and conflation in the definition and measurement of echo chambers. To address this, we provide a more precise conceptualization of echo chambers as narrowed information diversity accompanied by increased ideological polarization. By articulating and separating these two distinct dimensions, elaborating on their potential combinations, and detailing the process by which social media impacts online news consumption, we provide a generative framework for future research. We demonstrate the value of this framework through an analysis of social media usage and online news consumption based on four years of web browsing history for a representative panel of 200,000 US adults. We find that social media usage is associated with a combination of increased polarization and broadened information diversity. These results contradict the prevailing assumption that polarization and narrowing of information diversity are mutually reinforcing and that they typically occur together. Although our findings call in question the existence of echo chambers as typically understood, they nonetheless reinforce concerns about negative impacts of social media on polarization.

Speaker: Professor Johnson’s primary research area is online communities and other social media that support open innovation. Additional research interests include social network analysis, echo chambers, diversity, and emerging information technology. Professor Johnson has served as an associate editor for MIS Quarterly (2016-2019) and is an active member of the Organizational Communications and Information Systems division of the Academy of Management. They have taught numerous undergraduate and graduate courses, including systems and strategy, business analytics, and information technology management.




Title: Civil Liberties in the Age of Face Recognition

February 25th, 2020

Description: This talk will explore the unique risks that face recognition use by police poses to our constitutional rights and liberties, with a focus on the rights of the accused in criminal trials. Using the FOIA research that the Center on Privacy & Technology has done in this space, it will outline how the technology is currently used, as well as likely future deployments in the United States in the absence of proactive legislative action. It will also review the efforts underway in communities across the country to regulate or ban its use, as well as historical and recent court decisions that can help inform what legal protections exist vis-a-vis face recognition and related surveillance technologies. 

Clare Garvie

Speaker: Clare Garvie is a senior associate with the Center on Privacy & Technology at Georgetown Law. She was the lead author on The Perpetual Line-Up: Unregulated Police Face Recognition in America in 2016 and two follow-up reports. In 2019 she testified before the House Oversight Committee about police use of face recognition. Her commentary has appeared in The New York TimesThe Washington Post, and The Wall Street Journal, and she serves as an expert resource to both Democrats and Republicans in Congress and state legislatures. She received her J.D. from Georgetown Law and her B.A. from Barnard College in political science, human rights, and psychology. She is on Twitter at @ClareAngelyn





Title: Information infrastructures for creative knowledge work

March 10th, 2020

Description: What would our information infrastructure look like if it were optimized for creativity? Effective infrastructure is indispensable for enabling routine, effective work: so much of what we enjoy in modern civilization is under-girded by effective infrastructures like telephone networks, the Internet, shipping routes, truck highways, railroads, airways, standards for time, electrical systems, and so on. Information infrastructuressuch as search engines, classification systems, and libraries control how we access and assemble information to do information work. But are they designed with creative work in mind? What would our information standards and highways look like if they were designed so that creativity becomes more of a choice, and less of a chance occurrence? To answer this question, we need to integrate deep understanding of how creativity works (what is) with exploration of design possibilities (what could be). I am keen to discuss one particular thread we are exploring: how to build authoring tools that enable scholars and scientists to record their ideas (e.g., notes on literature they read, novel hypotheses and theories) in a way that makes it easier for themselves and others to remix for creative sensemaking and synthesis. The overarching goal is to significantly increase knowledge workers’ access to the full range of relevant knowledge for their work, including those that might lie outside their domains of expertise.

Dr. Joel Chan

Speaker: Joel Chan is an Assistant Professor in the University of Maryland’s College of Information Studies (iSchool), and Human-Computer Interaction Lab (HCIL). His research and teaching focus on the intersection of people, information, and creativity. He wants to know how they (can best) combine to enable us to design the future(s) we want to live in. His work has been recognized with a Best Paper Award at the ASME Design Theory and Methodology conference, the Design Studies Award 2015, and supported by an NSF Doctoral Dissertation Improvement Grant. Previously, he was a Postdoctoral Research Fellow and Project Scientist in the Human-Computer Interaction Institute at Carnegie Mellon University. He received his PhD in Cognitive Psychology at the University of Pittsburgh. Learn more about Joel Chan on his website and Twitter: @JoelChan86.
