Speaker:
David Lazer, Distinguished Professor of Political Science and Computer Sciences, Northeastern University
Title:
The Emergent Structure of the Online Information Ecosystem
Abstract:
This presentation examines the emergent and sometimes paradoxical logic of the internet news ecosystem, in particular: (1) collectively, news diets have become far more concentrated in a small number of outlets; (2) however, individuals have relatively diverse news diets-- almost certainly far more diverse than was plausible pre-Internet (as measured by number of unique content producers); (3) the social-algorithmic curation system of the Internet tends to point people to content with their preferences, sometimes in unlikely places. The greater diversity of consumption of news measured by number of unique outlets may not actually result in diversity of content.
Speaker Bio:
David Lazer is University Distinguished Professor of Political Science and Computer Sciences at Northeastern University. He has published widely on topics in computational social science, democratic deliberation, collective intelligence, and misinformation. He is cofounder and coleader of the Civic Health and Institutions Project (CHIP50), an ongoing 50 state survey evaluating the state of US democracy, and lead PI of the National Internet Observatory, a large ($16m) NSF supported data collection/sharing infrastructure designed to support the research on the platforms of the internet.
