Deb Roy reflects on machine learning and language modeling
October 3, 2025 (03:04)
By: MIT Media Lab
Media Lab Professor Deb Roy traces his path from studying how robots learn to founding the MIT Center for Constructive Communication (MIT CCC). The MIT CCC brings together researchers in AI, computational social science, digital interactive design, and learning technologies with software engineers, journalists, artists, public health experts, and community organizers to explore and address the effects of deepening societal fragmentation in America.
Selected Publications
Words Without Consequence
The Atlantic, 2026Argues that large language models produce speech that is behaviorally fluent but morally empty—carrying the force of promises, apologies, and advice without any speaker who bears consequence—eroding the conditions of dignity and accountability that make human language meaningful.
Conversation Networks
arXiv, 2025 (with Lawrence Lessig and Audrey Tang)Introduces a model for “conversation networks”—an alternative to social media (networks) designed to foster social connections, inform policy making, and strengthen democratic institutions at scale.
A Way to Put Public Thought in Front of Policymakers
Conference on Democratic “Frontsliding”, Princeton University, 2025 (with Kathy Cramer). Explores mechanisms for linking public deliberation with policymaking, aiming to close the gap between everyday civic voice and institutional decision-making.
How to Tackle Truth Decay
The Atlantic, 2024Argues that combating misinformation requires more than correcting falsehoods—it calls for fostering shared understanding through sustained, credible public communication, deliberation, and engagement.
The Internet Could Be So Good. Really.
The Atlantic, 2023Outlines a vision for reimagining the internet as infrastructure for civic life—designed to support deep conversation, collective understanding, and community resilience.
The Internet Needs You-Are-Here Maps
WIRED, 2022 (with Nabeel Gillani)Proposes interactive “maps” of the online information space to help users understand their own digital environments and discover perspectives beyond their usual feeds.
The Spread of True and False News Online
Science, 2018 (with Soroush Vosoughi and Sinan Aral)Demonstrates that false news spreads faster and more widely than true stories on Twitter, possibly driven by novelty and emotional engagement—highlighting structural flaws in social media design.
Journalists and Trump Voters Live in Separate Online Bubbles
Vice News, 2016Reveals deep divides in the social networks of journalists and conservative voters, offering early evidence of the information silos contributing to political polarization.
How Digital Transparency Became a Force of Nature
Scientific American, 2015 (with Daniel Dennett)Explores how digital transparency is disrupting traditional structures of trust and authority, as once-private actions become exposed to public scrutiny and institutional norms struggle to keep pace.

Biography
Roy received a bachelor of applied science in computer engineering from the University of Waterloo, and a PhD in Media Arts and Sciences from MIT.[1] He previously was the executive director of the MIT Media Lab and directed the Cognitive Machines group at the Media Lab,[2] and the Laboratory for Social Machines.
Roy conducts research on language, games, and social dynamics at the intersection of artificial intelligence and cognitive psychology. An author of over 150 academic papers[3][4] in machine learning, cognitive modeling, and human-machine interaction, his TED Talk, Birth of a Word (based on the 2006–2009 Human Speechome Project), has been viewed over 2.8 million times.[5]
In 2008, he co-founded and was the founding CEO of Bluefin Labs, a social TV analytics company, which MIT Technology Review named as one of the 50 most innovative companies of 2012.[6] Bluefin was acquired by Twitter in 2013,[7] and Roy served as chief media scientist of Twitter from 2013 to 2017. He is also co-founder and chairman of Cortico, a nonprofit media technology company whose Local Voices Network aims to foster constructive public conversations across political and cultural divides.[8]
The Laboratory for Social Machines started in 2014 with an investment of $10 million from Twitter over a five-year period.[9] The agreement also gives the lab access to all historical Twitter data and access to the firehose of all real-time tweets. The lab aims to "create new platforms for both individuals and institutions to identify, discuss, and act on pressing societal problems."[9]
In 2018, Soroush Vosoughi, Deb Roy, and Sinan Aral published "The spread of true and false news online" in Science.[10] The paper examined "~126,000 stories tweeted by ~3 million people more than 4.5 million times," and found that "Falsehood diffused significantly farther, faster, deeper, and more broadly than the truth in all categories of information, and the effects were more pronounced for false political news than for false news about terrorism, natural disasters, science, urban legends, or financial information." Additionally, the authors found that "Contrary to conventional wisdom, robots accelerated the spread of true and false news at the same rate, implying that false news spreads more than the truth because humans, not robots, are more likely to spread it."
