📢 Now online in AJPS (@ajpseditor.bsky.social)! With Katie Clayton, Aaron Kaufman, @kinggary.bsky.social , and @mayyakomis.bsky.social, we offer a unified framework for conjoint analysis—and argue for analyzing data at the CHOICE level. 📊 📄 doi.org/10.1111/ajps... 🛠️ yhoriuchi.github.io/projoint/

📘 I revised my Guide to Recording AI Use following helpful comments from Gary King & an excellent discussion at Polmeth. A practical, tool-agnostic way to document substantive AI-assisted research automatically. 🤖📝 🔗 yhoriuchi.github.io/ai-collabora... Please share widely! 🔄🌍 Comments welcome. 💬

I made 3 practical guides for using AI agents in research workflows 🤖📚 📦 Replication packages yhoriuchi.github.io/replication-... 🧹 BibTeX cleaning yhoriuchi.github.io/bibtex-clean... ✍️ Shared Overleaf projects yhoriuchi.github.io/ai-collabora... Please share with researchers/students 🙏

🎉 Delighted to share my new website: horiuchi.org For years, I dreamed of an academic website with 🔎 searchable research records, 📝 blog posts, and 📄 consistency with my CV. I built it with help from Codex 🤖 It even includes an AI-generated illustration of me—with a new pair of glasses! 👓✨

Excited to announce that jpmap + jpmapdata are now ready on CRAN! 🇯🇵🗺️📦 From initial idea to CRAN submission took less than 24 hours with OpenAI Codex running GPT-5.5 in Extra High Intelligence mode. 🤖⚡ yhoriuchi.github.io/jpmap/

📦✨ New version of my Replication Package Guide is live! I added a copy button so researchers can paste the full instructions directly into Codex, Claude Code, or another coding agent. Make social science replication packages easier to prepare, audit, and share. yhoriuchi.github.io/replication-...

New guide! 🤖📚 A BibTeX Cleaning Agent Guide for researchers using AI to clean .bib files carefully and transparently. 🔗 yhoriuchi.github.io/bibtex-clean... Please share with LaTeX users.

My article with Atsushi Tago is now OnlineFirst in @conflictmanagement.bsky.social . We examine Japanese public opinion toward the 2021 SDF evacuation from Afghanistan, focusing on civilian control, legality, and casualty sensitivity. 🔗 doi.org/10.1177/0738...

#OpenAccess from the Journal of Law and Courts - The Supreme Court’s Partisan Composition Affects How Americans Evaluate Nominees: Evidence from a Conjoint Experiment - https://cup.org/4xGjmOT - @victorywu.bsky.social & @yusakuhoriuchi.bsky.social #FirstView

🎉 New article in Journal of Law and Courts with @victorywu.bsky.social, my former Dartmouth student and now a PhD/JD student at Stanford. It began as his independent study at Dartmouth. 👏 We show that Supreme Court composition shapes how Americans evaluate nominees. DOI: doi.org/10.1017/jlc....

Please join us to hear about three exciting research projects by our fellows. It should be a wonderful session!

The second research showcase from the APSA Experimental Research Section Early Career Fellows is around the corner: June 10 11am Eastern time. Zoom link: Horiuchi.org/zoom Exciting new work on (1) housing, (2) depolarization and (3) gendered foreign policy. @experimentsapsa.bsky.social

📢 The deadline is approaching for the APSA Experimental Research Section’s 2nd Experimental Research Early-Career Fellowship! 🌱 Please consider applying, and please share this opportunity with promising early-career scholars who may be interested. 🔗 forms.gle/fXHaqYK3TEL3...

📢 New paper out in @isq-jrnl.bsky.social! @rinouye.bsky.social and I examine Americans’ selective sympathies toward Israelis and Palestinians. OA: doi.org/10.1093/isq/... Methodologically, we use "choice-level" conjoint analysis to examine how different attributes shape comparative evaluations.

Bluesky I made a public guide for preparing social science replication packages 📦 yhoriuchi.github.io/replication-... Please repost if this might help researchers preparing replication materials.

The first session is tomorrow! Please share this announcement with anyone who may be interested in this research showcase!

#OpenAccess from @journalrep.bsky.social - Disclosing Invisible Attributes Leads to Discrimination - https://cup.org/4uSIQa8 - Kai Zhou & @yusakuhoriuchi.bsky.social #FirstView

From February 2026 - Descriptive or Partisan Representation? Examining Trade-Offs for Asian Americans - https://cup.org/45Y91Bz - John J. Cho, @miacosta.bsky.social & @yusakuhoriuchi.bsky.social #OpenAccess

New paper with Martha Johnson in APSR (@apsrjournal.bsky.social)😀 — Open Access 🎉📄 lnkd.in/eEPUxdi8 1) Terrorism ≠ rally effects. 2) Do women leaders face unique crisis penalties? No evidence. 3) Event-during-survey → trends matter ⚠️

New paper (with Kai Zhou) in @journalrep.bsky.social: “Disclosing Invisible Attributes Leads to Discrimination" (doi.org/10.1017/rep....). This project builds on Kai’s honors thesis at Dartmouth. Another application of "choice-level" conjoint analysis (gking.harvard.edu/conjointE).

5/6 🧵In @bjpols.bsky.social, Cho, @miacosta.bsky.social & @yusakuhoriuchi.bsky.social study trade-offs between descriptive & partisan representation for Asian-Americans. Clear preference for partisanship over ethnicity. True co-ethnics preferred over pan-ethnic & cross-ethnic. doi.org/qtv8

@bjpols.bsky.social New Open Access article in the BJPS cup.org/45Y91Bz. Examine how Asian Americans weigh descriptive vs. partisan representation—and demonstrate the value of "choice-level" conjoint analysis (see forthcoming AJPS: gking.harvard.edu/conjointE). Earlier version = Cho’s honors thesis!

New working paper: "To Compare or Not to Compare: Testing the Effects of Profile Comparison in Conjoint Analysis" (with Martha Johnson). Key takeaway: when theory is comparative, analysis should be at the choice level. papers.ssrn.com/sol3/papers....
