You Never Can Tell: A Survey of Preferences on LLM-Generated Counterspeech in an Austrian Context

Pia Pachinger, Arianna Muti


Abstract
We present the first survey study of German-language counterspeech in an Austrian context, where participants ranked LLM-generated responses to offensive comments involving xenophobia, sexual objectification, and political incivility. We compare generations from five state-of-the-art LLMs and additionally examine whether participants perceive them as human- or machine-written. Our results show substantial disagreement in rankings, indicating that counterspeech preferences are highly subjective. Although participants express a clear preference for human-written counterspeech in real-world settings, they fail to reliably identify LLM-generated responses as machine-written. These findings point to the need for personalized counterspeech systems that account for users’ diverse preferences, rather than assuming a single universally effective response. Such systems could combine LLMs’ capacity to generate high-quality counterspeech at scale with human involvement.
