Researchers from KDDI Research, Inc. and Stanford University developed PersuaBot, a zero-shot persuasive chatbot that leverages LLMs to dynamically generate nuanced persuasion strategies and ensure factual accuracy. The system consistently achieves high factuality by replacing unsubstantiated claims with retrieved information while maintaining persuasive intent, leading to enhanced persuasiveness in diverse applications like donation solicitation, travel recommendations, and health intervention.

Key insights

  • LLMs can dynamically generate and adapt a broad range of nuanced persuasion strategies, significantly exceeding the limitations of pre-defined sets in previous work.
  • It is possible to maintain a chatbot's persuasive intent while rigorously ensuring factual accuracy by strategically replacing fabricated information with verified facts rather than merely discarding it.
  • A zero-shot framework combining dynamic strategy generation and robust factual grounding can create effective and trustworthy persuasive AI for various 'social good' applications.
