We are delighted to welcome @marlutz.bsky.social to our lab over the next few months! 🎉
She'll work on the representation of different demographic groups in LLMs.
#NLProc
Survey-style tests developed for humans may not predict how LLMs actually behave.
Our #EACL2026 paper shows they can even be misleading when measuring racism and sexism!
Check out the paper 👇🏼

🚨New paper alert🚨
🤔 Ever wondered how the way you write a persona prompt affects how well an LLM simulates people?
In our #EMNLP2025 paper, we find that using interview-style persona prompts makes LLM social simulations less biased and more aligned with human opinions.

Very honored to be one out of seven outstanding papers at this years' EMNLP :)
Huge thanks to my amazing collaborators @fatemehc.bsky.social @anamarasovic.bsky.social @boknilev.bsky.social , this would not have been possible without them!
Are you using survey-style questionnaires designed for humans to measure characteristics of LLMs?
In our #EACL2026 paper, we evaluate both the reliability and validity of such tests and found that their scores do not reflect real-world model behavior. In fact, they can be deceptive!
