  In 2018 the European Commission highlighted the demand of a human-centered
approach to AI. Such a claim is gaining even more relevance considering
technologies specifically designed to directly interact and physically
collaborate with human users in the real world. This is notably the case of
social robots. The domain of Human-Robot Interaction (HRI) emerged to
investigate these issues. "Human-robot trust" has been highlighted as one of
the most challenging and intriguing factors influencing HRI. On the one hand,
user studies and technical experts underline how trust is a key element to
facilitate users' acceptance, consequently increasing the chances to pursue the
given task. On the other hand, such a phenomenon raises also ethical and
philosophical concerns leading scholars in these domains to argue that humans
should not trust robots. However, trust in HRI is not an index of fragility, it
is rooted in anthropomorphism, and it is a natural characteristic of every
human being. Thus, instead of focusing solely on how to inspire user trust in
social robots, this paper argues that what should be investigated is to what
extent and for which purpose it is suitable to trust robots. Such an endeavour
requires an interdisciplinary approach taking into account (i) technical needs
and (ii) psychological implications.
