AI agents simulate negotiations for new insights
Researchers have developed a new methodology, "personality engineering", which uses AI agents to study negotiations. This allows for precision in the parameterisation and manipulation of negotiators' personalities.

What happened?
A new research study presents "personality engineering", a method leveraging AI agents to simulate and analyse negotiation processes. The method aims to precisely parameterise, manipulate, and evaluate negotiation personalities. The interpersonal circumplex model, featuring dimensions of warmth and dominance, is proposed as a foundational coordinate system for the field.

”According to canonical negotiation theory, people's success in a negotiation depends on how well they balance competing demands--empathizing and asserting, demonstrating concern for other and concern for self, being soft on the people and hard on the problem. Yet people struggle”
”AI agents do not face the same limitations, and their precision, repertoire, consistency, and scalability enable a new class of experiments to contribute to negotiation theory.”
”In this article, we introduce personality engineering: a methodology that uses AI agents to precisely parameterize, manipulate, and evaluate negotiator personality. We propose using the interpersonal circumplex--and its two core dimensions of warmth and dominance--as a foundation”
Why it matters
Traditional negotiation research has struggled with limitations in controlling variables. The precision, consistency, and scalability of AI agents bridge these hurdles and enable rigorous experimentation. This could lead to new insights into how negotiations function and thereby improve negotiation theory.
Who is affected?
The methodology is primarily relevant to researchers in negotiation theory, psychology, and AI ethics. Developers of AI models that interact with humans can also benefit from the insights to create more nuanced and effective AI systems.
What else you should know
The study was published as a preprint on arXiv on May 26, 2026. It has not yet undergone peer review.
