Does human-robot trust need reciprocity?

TL;DR

This paper explores whether reciprocity is essential for mutual trust in human-robot interactions, challenging the traditional unidirectional focus on robot reliability and proposing a more dynamic, bidirectional trust model.

Contribution

It introduces the idea that reciprocity may be crucial for mutual trust in HRI, highlighting the need to consider bidirectional trust dynamics.

Findings

Reciprocity influences trust development in HRI.

Current research predominantly views trust unidirectionally.

A bidirectional trust framework could enhance human-robot collaboration.

Abstract

Trust is one of the hallmarks of human-human and human-robot interaction. Extensive evidence has shown that trust among humans requires reciprocity. Conversely, research in human-robot interaction (HRI) has mostly relied on a unidirectional view of trust that focuses on robots' reliability and performance. The current paper argues that reciprocity may also play a key role in the emergence of mutual trust and successful collaboration between humans and robots. We will gather and discuss works that reveal a reciprocal dimension in human-robot trust, paving the way to a bidirectional and dynamic view of trust in HRI.
