Previous research has shown that individuals high in narcissism mistrust others, yet little is known about narcissism’s relation to trust. In the current study (N = 727), we aim to close this gap in the literature by examining the relationship between facets of trust (i.e., cognitive bias in the evaluation of others and personal trustworthiness) and facets of grandiose narcissism (i.e., agentic, antagonistic, and communal). We strive to answer the question whether narcissistic individuals believe that others are reliable, honest, and benevolent (how they perceive others) and whether they present themselves as trusting of others (how they perceive themselves). We posit and show that agentic narcissism is not related to any of the studied trust facets, suggesting that the concept of trust is not relevant to their self-image. In contrast, antagonistic narcissism is negatively related to perceiving others and oneself as trustful, and communal narcissism is positively related to these trust facets, purportedly due to communal self-enhancement. We discuss our findings of the Narcissistic Admiration and Rivalry Concept as well as to the Agency-Communion model of grandiose narcissism.
