This paper asks three fundamental questions on the nature of trust: What is trust? What is trustworthiness? When is trust warranted? These discussions are then applied to the context of Human-Robot Interaction (HRI), asking whether we can trust social robots, whether they can be trustworthy, and, lastly, whether we should trust them. After revising the literature on the nature of trust and reliance on one hand, and on trust in social robots, considering both properties-based and non-properties-based views, on the other (...) hand, this paper defends that, given the current state of technology, we can be subjects of a paradoxical scenario in which there is trust without trustworthiness, i.e., human users that interact with social robots can develop something resembling interpersonal trust towards an artificial entity which cannot be trustworthy. This occurs because we perceive and treat social robots as trustworthy entities, while they seem to lack certain properties that would make them capable of being trustworthy (as well as untrustworthy). Understanding our psychology in HRI and trying to discern what social robots are (and are not) is capital when confronted with ethical issues. Some of the ethical issues that arise in the context of trust without trustworthiness will be considered to address the debate about if we should trust social robots. This paper concludes that we should, at least for now, not trust social robots, given the potential harms that can be done and the responsibility gaps that might appear when these harms are to be repaired.

The widespread use of voice-assisted applications using artificial intelligence raises questions about the dynamics of trust and reliance on these systems. While users often rely on these applications for help, instances where users face unforeseen risks and heightened challenges have sparked conversations about the importance of fostering trustworthy artificial intelligence. In this paper, we argue that the prevailing narrative of trust and trustworthiness in relation to artificial intelligence, particularly voice assistants, is misconstrued and fundamentally misplaced. Drawing on insights from philosophy (...) and artificial intelligence literature, we contend that artificial intelligence systems do not meet the criteria for participating in a relationship of trust with human users. Instead, a narrative of reliance is more appropriate. However, we investigate the matter further, to explore why the trust/trustworthiness narrative persists, focusing on the unique social dynamics of interactions with voice assistants. We identify factors such as diverse modalities and complexity, social aspects of voice assistants, and issues of uncertainty, assertiveness, and transparency as contributors to the trust narrative. By disentangling these factors, we shed light on the complexities of human-computer interactions and offer insights into the implications for our relationship with artificial intelligence. We advocate for a nuanced understanding of trust and reliance in artificial intelligence systems and provide suggestions for addressing the challenges posed by the dominance of the trust/trustworthiness narrative.
