This paper was a blast to work on. The challenge: present party positions across many issues, in real time, using language voters actually use. 🧵 on why we went with a more involved retrieval-based approach and where I think these tools are headed.

An AI Voter bot improves knowledge about politics But, the AI bot has weak effects on downstream outcomes like vote preferences and party evaluations among respondents whose primary issue position aligns closely with one of the parties. Partisan action is hard to change. www.pnas.org/doi/10.1073/...

🚨Excited to share our new paper published in PNAS (joint with @yamilrvelez.bsky.social and Don Green)! AI can enhance political knowledge and provide balanced information about politics with proper guardrails and vetted sources (e.g., party platforms). www.pnas.org/doi/full/10....

Quite a 24 hours in Canadian Politics, two Conservatives out (one to the Liberals, one gone altogether), a new Budget on the table, and my debut on Power & Politics! Nothing beats watching your research come to life. Full interview here: gem.cbc.ca/power-politics #cdnpoli

Our study of every election since 1867 shows party switchers in Canada once thrived, but now they face steep losses. Here is a summary of our results: policyoptions.irpp.org/2018/09/rese... #cdnpoli

@utoronto.ca, do better! The Uni is excluding recent hires from cost-of-living adjustments that an arbitrator decided ALL faculty/librarians deserve. This harms junior colleagues struggling w/ inflation: we’ve organized a petition demanding @utoronto.ca change course. Spread the word! www.utfa.org

Which Canadian MPs are on Bluesky and what do they post? My new paper w/ @rohanalexander.bsky.social in @cjps-rcsp.bsky.social unpacks these questions, finding MPs use it like Twitter to discuss policy, the Ottawa bubble & constituency Read more: doi.org/10.1017/S000... #polsky #commsky #cdnpoli

🚨NEW STUDY: Do Americans support a woman president? Our list experiment during the 2024 election, when @kamalaharris.com was on the ballot, reveals hidden bias, and it's more widespread than you'd expect. journals.sagepub.com/doi/10.1177/...

🪃Do legislators trade proposals? ➡️Leveraging a lottery in the Canadian Parliament, @semrasevi.bsky.social & D.P. Green find little evidence MPs second motions to gain favor. Support seems driven by shared interests, not quid pro quo www.cambridge.org/core/journal... #FirstView

🚨NEW PAPER: Do legislators trade favours? My latest with Donald Green uses a natural lottery in the Canadian Parliament to test whether MPs return favours when others support their proposals. Our findings may surprise you.👇 www.cambridge.org/core/journal...

🚨NEW PAPER: Do incumbents really have an edge in elections? Research says yes. But what happens when party labels are added to the ballot? A natural experiment from Canadian elections tells an interesting story👇🧵

Can AI reduce prejudice? 🇺🇸 In our new preprint, GPT-4o moved the needle on trans rights in a national U.S. study using morally tailored messages. The shift was real and short-lived. For more, read 👇 Comments and feedback are welcome.

Prejudice is common in modern societies. Reducing prejudice is difficult to do, particularly in a cost-effective & scalable manner. Can AI help reduce prejudice? My new working paper w @semrasevi.bsky.social, @mbosley.bsky.social & Crabtree examines this question! papers.ssrn.com/sol3/papers....

Why aren't we talking about harassment in #elxn45? In my new op-ed, I reflect on the harassment women continue to face in #cdnpoli, and the threat it poses to democracy: theconversation.com/growing-thre... @theconversationca.bsky.social #gendersky #polisky
