super interesting. We are working on new cohorts in the refugee support movement in the wake of the Ukrainian refugee influx. Think your model here can help clarify some stuff!

Looks like a super useful application.

Thanks to my co-authors Semra, Tobias and @andbjn.bsky.social and to the @villumfonden.bsky.social foundation and @cphsodas.bsky.social who have both founded the AI-interview project.

Of course, there are big challenges to this kind of experimental comparison 🧵

1) Data quality in qual interviews isn’t standardized
2) It’s rarely operationalized as quantitative measures
3) Chat-based interviews ≠ in-depth, face-to-face interviews
4) Small N

Important limitations to keep in mind.

Why this matters 🧵

1) AI-interviewers can yield reasonable data quality, supporting their promise for large-scale qualitative research.

2) As opposed to other AI-interview studies, we used a locally hosted, open-weight model—boosting data security, transparency & reproducibility.

Key results 🧵:
🧠 Human-led: longer answers per question
🕐 AI-led: longer interviews overall (faster question delivery)
📋 No dif in response quality (specificity + relevance)

LLMs do pretty well—
But responses are short compared typical qualitative interviews.
