New in Terrorism & Political Violence: Why did radical environmental groups stop using arson & sabotage? And, given the threat from climate change why haven't those tactics returned? My article "Where's the Sabotage" seeks to answer these questions. Free link: www.tandfonline.com/eprint/QYFAW...

the new paper on bouba/kiki in chicks is utterly compelling canonical, elegant method from comparative cogsci & its partner in developmental science, ultra-simple design, ultra-clear effects, no need for fancy analyses, machine learning, or AI it appeared in an appropriately badass venue (Science)

This new paper offers practical solutions for pluralistic ignorance (when people assume their opinon is unpopular when many others share it): -in loose cultures, share accurate information -in tight ones, lowering the costs of speaking up can spark social change. www.pnas.org/doi/10.1073/...

Automated nuclear weapons systems are not just a Hollywood plot device. In this #Firstview article, @joshschwartz.bsky.social and @mchorowitz.bsky.social evaluate how they could impact the credibility and effectiveness of nuclear threats. www.cambridge.org/core/journal...

When leaders frame disputed land as “territory we might lose” rather than “new land to gain,” people in Argentina & Chile become more willing to support risky escalation and less willing to compromise. New study by @andizhou.bsky.social: https://loom.ly/cjdEJkM

A new paper finds ideological bias in research analyses: Research teams composed of pro-immigration researchers estimated more positive impacts of immigration on public support for social programs, while anti-immigration teams estimated more negative impacts. science.org/doi/10.1126/...?

Apropos current events, I want to tout this paper by @soyounglee.bsky.social showing that discussion of economic benefits can reduce public support for military action. People are skeptical when they think specific groups (e.g., oil companies) will benefit. www.cambridge.org/core/journal...

New paper in @ajpseditor.bsky.social. Is descriptive representation good for substantive representation? Why do voters stay loyal to corrupt and poorly governing ethnic parties? I argue that we ought to focus less on patronage and more on dignity concerns. Defiant pride can come at a price. 1/🧵

Does public opinion matter for nuclear policy? We say yes, in @ejisbisa.bsky.social. Whether the public backs nuclear use can sway leaders’ preferences and affects external perceptions of the credibility of deterrence. doi.org/10.1017/eis....

We propose a spatiotemporal causal inference framework that fully leverages microlevel, granular data. ATE, heterogeneity, and mediation — all in one framework. Now with updated results and visualizations!

How can we identify causal effects using micro-level data? Our new framework estimates ATEs, probes causal mechanisms, and uncovers heterogeneity—all in one. We illustrate it with an analysis of airstrikes and insurgent attacks in Iraq. arxiv.org/abs/2504.03464

Delighted and honored to receive the 2025 Karl Deutsch Award from the International Studies Association. I attribute this almost entirely to my luck in having amazing colleagues, mentors, collaborators and students over the years; I've been incredibly fortunate. @isanet.bsky.social #ISA2025
