Social media systems typically display conversations among already familiar contributors, which can be predictable and one-sided. In civic discourse, this design narrows discussion…
The Agentic Web Requires New Normative Infrastructure
Cameron Pattison, Matthew Boulos, Noam Kolt +3
The agentic web, in which users interact with the internet largely through agents acting on their behalf, is now technically feasible. However, many of the consumer and social bene…
Social Media Feed Elicitation
Lindsay Popowski, Xiyuan Wu, Charlotte Zhu +2
Social media users have repeatedly advocated for control over the currently opaque operations of feed algorithms. Large language models (LLMs) now offer the promise of custom-defin…
Permission Manifests for Web Agents
Samuele Marro, Alan Chan, Xinxing Ren +12
The rise of Large Language Model (LLM)-based web agents represents a significant shift in automated interactions with the web. Unlike traditional crawlers that follow simple conven…
Whose Values? Measuring the (Subjective) Expression of Basic Human Values in Social Media
Ziv Epstein, Farnaz Jahanbakhsh, Tiziano Piccardi +4
The value alignment of sociotechnical systems has become a central debate, but progress depends on how human values are perceived in the content these systems surface and how such…
Value Alignment of Social Media Ranking Algorithms
Farnaz Jahanbakhsh, Dora Zhao, Tiziano Piccardi +4
While social media feed rankings are primarily driven by engagement signals rather than any explicit value system, the resulting algorithmic feeds are not value-neutral: engagement…
Burst: Collaborative Curation in Connected Social Media Communities
Yutong Zhang, Taeuk Kang, Sydney Yeh +4
Positive social interactions can occur in groups of many shapes and sizes, spanning from small and private to large and open. However, social media tends to binarize our experience…

Reranking partisan animosity in algorithmic social media feeds alters affective polarization
Tiziano Piccardi, Martin Saveski, Chenyan Jia +3
Today, social media platforms hold sole power to study the effects of feed ranking algorithms. We developed a platform-independent method that reranks participants' feeds in real-t…
Reranking Social Media Feeds: A Practical Guide for Field Experiments
Tiziano Piccardi, Martin Saveski, Chenyan Jia +3
Social media plays a central role in shaping public opinion and behavior, yet performing experiments on these platforms and, in particular, on feed algorithms is becoming increasin…
AnthroScore: A Computational Linguistic Measure of Anthropomorphism
Myra Cheng, Kristina Gligoric, Tiziano Piccardi +1
Anthropomorphism, or the attribution of human-like characteristics to non-human entities, has shaped conversations about the impacts and possibilities of technology. We present Ant…
CoMPosT: Characterizing and Evaluating Caricature in LLM Simulations
Myra Cheng, Tiziano Piccardi, Diyi Yang
Recent work has aimed to capture nuances of human behavior by using LLMs to simulate responses from particular demographics in settings like social science experiments and public o…
In-class Data Analysis Replications: Teaching Students while Testing Science
Kristina Gligoric, Tiziano Piccardi, Jake Hofman +1
Science is facing a reproducibility crisis. Previous work has proposed incorporating data analysis replications into classrooms as a potential solution. However, despite the potent…
Characterizing Image Accessibility on Wikipedia across Languages
Elisa Kreiss, Krishna Srinivasan, Tiziano Piccardi +5
We make a first attempt to characterize image accessibility on Wikipedia across languages, present new experimental results that can inform efforts to assess description quality, a…
Curious Rhythms: Temporal Regularities of Wikipedia Consumption
Tiziano Piccardi, Martin Gerlach, Robert West
Wikipedia, in its role as the world's largest encyclopedia, serves a broad range of information needs. Although previous studies have noted that Wikipedia users' information needs…
Going Down the Rabbit Hole: Characterizing the Long Tail of Wikipedia Reading Sessions
