Join the Cyber Policy Center, together with the Program on Democracy and the Internet on Tuesday, January 31st, from Noon–1 PM Pacific, for "The Emergent Structure of the Online Information Ecosystem" a discussion with David Lazer, Professor of Political Science and Computer Sciences at Northeastern University and Director of the Lazer Lab. The session will moderated by Nate Persily, Co-Director of the CPC and James B. McClatchy Professor of Law at Stanford Law School.

The first part of 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.

The second part of the presentation will discuss the development of the National Internet Observatory, a large, NSF-supported effort to create a privacy-preserving data collection/data analytic system for the broader research community.

This session is part of the Winter Seminar Series, a series spanning January through March, hosted at the Cyber Policy Center with the Program on Democracy and the Internet. Sessions are in-person and virtual, with in-person attendance offered to Stanford affiliates only. Lunch is provided for in-person attendance.

In person attendance is available to Stanford affiliates and virtual attendance via zoom is open to the public; registration is required.
