Great work from our colleague Tobias Werner! Delighted to see this research on #LLM pollution in online behavioural experiments published in Nature Communications. A timely contribution to understanding #AI's impact on research. Article: tinyurl.com/435xyj4k #econtwitter #econsky

Recognising and mitigating LLM Pollution in online behavioural research - Nature Communications Online behavioural research faces a growing methodological and epistemic threat as participants increasingly rely on large language models: LLM Pollution. Amid accumulating empirical evidence of contamination, we introduce a conceptual framework that distinguishes three variants — Partial LLM Mediation, Full LLM Delegation, and LLM Spillover. Their interaction distorts samples, biases inferences, and fuels an escalating methodological arms race. We outline mitigation strategies spanning researcher practices, platform accountability, and community adaptation. https://tinyurl.com/435xyj4k
