What can surveys miss when respondents choose the same answer option? In this pre-print, we argue that public opinion research needs not only to know where respondents stand, but how they think. AI Conversational Interviewing is one way to make that observable at scale

AI Conversational Interviewing: Scaling Up Semi-Structured and In-depth Interviews
Public opinion research has long faced a trade-off between depth and scale: standardized surveys enable large-scale measurement but restrict respondents to researcher-defined categories, obscuring the diversity of unexpected considerations that underlie public sentiment. More conversational interviews provide richer insights through open-ended probing, but their reliance on trained human interviewers has kept them difficult to scale. This study introduces AI Conversational Interviewing as a method for collecting open-ended public opinion data at scale, pursuing three objectives: to demonstrate the analytical value of conversational text data for questions beyond the reach of closed-ended items; to assess the method's practical viability through participants' own evaluations; and to inform implementation by experimentally comparing voice-based, chat-based, and free-choice interview modes. We conducted a study combining an AI-led interview with a standardized survey on migration policy among 571 respondents recruited via Prolific and Payback Panel. The findings establish AI Conversational Interviewing as a viable and valuable addition to the social-science toolkit. The conversational transcripts surface considerations and reasoning that a comprehensive standardized battery does not capture such as markedly different mental models of migration among subgroups with similar attitudes levels. Among respondents who completed the interview, evaluations of the AI interview were at or above those of the standardized survey across modes, although completion itself varied by condition. By releasing open data and open-source pipeline materials, the study contributes to a growing literature on harnessing artificial intelligence to expand the methods of public opinion measurement.

I worry that initiatives like this will break pro-social norms. Willingness to give feedback generously is one of the most beautiful things in our community. Plus, universities pay profs with the understanding that this is part of the job description, so the idea we do this for "free" is laughable.

Incentives to reproduce and replicate articles are so bad. Even when your comment leads to the retraction of a PLOS One article, the reward is a (10 days late) email with a thank you at the bottom. Retraction notice: journals.plos.org/plosone/arti.... But we are not complaining about PLOS One 🧵

🚨 #RStats and #PyData devs! I'm looking for β testers for this thing I just built: A unified dashboard + orchestrator for code and data quality checks. It has lots of neat features and I'm super eager for feedback and bug reports. Check out the video demo: vincentarelbundock.github.io/scrutin/

A Unified Dashboard and Orchestrator for Quality Checks¶

Unit tests · Data validation · Linting · Spelling

Run every quality check on your project using a single command: unit tests, data validation, linters, spell checkers. Scrutin watches for edits, figures out which checks are affected, and re-runs them in parallel. Drill into a failure to see the expected and actual values, as well as the relevant source code. Use quick keystrokes to fix linting and spelling issues, or to open files in your editor of choice.
