Trust Formation for Artificial Intelligence in Continuous Mutual Transactions

Comparison of the trust game when the counterparty is a "human" and a "robot"

Abstract

The purpose of this research is to clarify the mechanism of trust formation in mutual economic transactions between humans and AI. Nowadays, there are more and more opportunities for long-term relationships between humans and robots, such as nursing robots and asset management robots. Trust is essential in such continuous mutual transactions, and various studies have been conducted on trust between humans and robots. In this experiment, we examined the relationship between emotion and trust in a continuous trust relationship using a trust game with repetitions for both human-human and human-robot. The results showed that social emotions (gratitude and anger) had no effect on trust in a continuous relationship. However, the amount of money transferred for human was larger than robots in successful transactions (Return minus Investment≧0), and in unsuccessful condition (RMI≦0), one for humans was smaller than robots. This has implications for the cooperative behavior of humans and AI.
