I have a new paper out in @sociologicalsci.bsky.social w/ the briliant @aybukeatalay.bsky.social and @aliaelkattan.com We show that what we pay attention to online is a lot more politically diverse than what public engagement signals would suggest... sociologicalscience.com/articles-v13...

I’m excited to share a new paper in Nature that shows how large language models launder the strategic rhetoric of authoritarian states. Paper here: www.nature.com/articles/s41.... A thread.

State media control influences large language models - Nature

Government-controlled media influences the output of large language models via their training data, and models queried in the languages of countries with lower media freedom show a stronger ...

New in Nature: LLMs give "the party line" in the languages of authoritarian regimes. This works when they control the media, which feeds pretraining data. We show more state control over the media means less critical LLMs. 6 studies spanning 38 languages & 13 models. Details ↓

You can just research things. New from @jatucker.bsky.social & me at @brookings: Coding agents like Claude Code and Codex will likely accelerate research AND undermine institutional structures we built to support it.

CSMaP is now the Center for Social Media, AI, and Politics (CSMAP). Our research has expanded beyond social media to include digital media more broadly—especially generative AI and large language models and their role in politics and public life. Learn more at csmapnyu.org

When we think about false news stories, we usually focus on what is being said. But what if the language of a story shapes whether people believe it? Our new paper in the Journal of Experimental Political Science explores this question in Ukraine. www.cambridge.org/core/journal...

LLMs are now widely used in social science as stand-ins for humans—assuming they can produce realistic, human-like text But... can they? We don’t actually know. In our new study, we develop a Computational Turing Test. And our findings are striking: LLMs may be far less human-like than we think.🧵

Computational Turing Test Reveals Systematic Differences Between Human and AI Language

Large language models (LLMs) are increasingly used in the social sciences to simulate human behavior, based on the assumption that they can generate realistic, human-like text. Yet this assumption rem...

🚨 Paper now as "just accepted" at @The_JOP. We ran the first WhatsApp deactivation experiment focused on multimedia content ahead of the 2022 election in Brazil. We find a reduction in users' recall of false rumors -- and, to a smaller degree, of true news. Null effects on attitudes. Full thread ⬇️

In the Global South, WhatsApp is more popular than X or Facebook. New in @The_JOP, we ran a WhatsApp deactivation experiment during Brazil’s 2022 election to explore how the app facilitates the spread of misinformation and affects voters’ attitudes. www.journals.uchicago.edu/doi/abs/10.1...

Abstract: In most advanced democracies, concerns about the spread of misinformation are typically associated with feed-based social media platforms like Twitter and Facebook. These platforms also account for the vast majority of research on the topic. However, in most of the world, particularly in Global South countries, misinformation often reaches citizens through social media messaging apps, particularly WhatsApp. To fill the resulting gap in the literature, we conducted a multimedia deactivation experiment to test the impact of reducing exposure to potential sources of misinformation on WhatsApp during the weeks leading up to the 2022 Presidential election in Brazil. We find that this intervention significantly reduced participants’ recall of false rumors circulating widely during the election. However, consistent with theories of mass media minimal effects, a short-term change in the information environment did not lead to significant changes in belief accuracy, political polarization, or well-being.

In addition to the original UK results, we have now ***replicated*** this (TWICE) in the US. The main findings hold strong: information diets are a lot more diverse in attention than in engagement. New version here: osf.io/preprints/os...

🚨New Publication @thejop.bsky.social We study who sets the issue agenda of state policymakers in the US. We find a mixed picture: they respond to shifts in attention by members of Congress, but also to the constituents in their states, particularly their own party supporters.

Amid growing DC gridlock, state legislatures play a vital role in shaping policy. But how do state lawmakers decide which issues deserve their attention? Our new @thejop.bsky.social paper is the first large-scale multi-state analysis exploring this question www.journals.uchicago.edu/doi/10.1086/...

Title: Bottom Up? Top Down? Determinants ofIssue-Attention in State Politics Abstract: Who shapes the issue-attention cycle of state legislators? Although state governments make critical policy decisions, data and methodological constraints have limited re-searchers’ ability to study state-level agenda setting. For this paper, we collect more than 122 million Twitter messages sent by state and national actors in 2018 and 2021.We then employ supervised machine learning and time series techniques to study how the issue-attention of state lawmakers evolves vis-`a-vis various local- and national-level actors. Our findings suggest that state legislators operate at the confluence of national and local influences. In line with arguments highlighting the nationalization of state politics, we find that state legislators are consistently responsive to policy debates among members of Congress. However, despite growing nationalization concerns, we also find strong evidence of issue responsiveness by legislators to members of the public in their states and moderate responsiveness to regional media sources.

New paper out in @thejop.bsky.social with my colleagues at @csmapnyu.org . Substantive findings are summarized in the thread below. Of interest to a broader sociological audience: we show how to measure discursive influence between different groups.
