Large language models can enhance behavioral nudges by providing personalized guidance and updating it iteratively

advanced Published 7 Apr 2026
Action Steps
  1. Develop an LLM agent for iterative personalization
  2. Test the LLM agent in a field experiment with multiple intervention rounds
  3. Analyze the effectiveness of the LLM-based approach compared to traditional nudging methods
  4. Refine the LLM agent based on the results and iterate on the personalization process
Who Needs to Know This

Data scientists and AI engineers on a team can benefit from this research as it demonstrates the potential of LLMs in behavioral change interventions, and product managers can apply these insights to design more effective personalized feedback systems

Title: Enhancing behavioral nudges with large language model-based iterative personalization: A field experiment on electricity and hot-water conservation

Abstract:
arXiv:2604.03881v1 Announce Type: cross Abstract: Nudging is widely used to promote behavioral change, but its effectiveness is often limited when recipients must repeatedly translate feedback into workable next steps under changing circumstances. Large language models (LLMs) may help reduce part of this cognitive work by generating personalized guidance and updating it iteratively across intervention rounds. We developed an LLM agent for iterative personalization and tested it in a three-arm ra
