Charting the neuroscience of interpersonal trust: A bibliographic literature review.

Interpersonal trust is essential for societal well-being, underpinning relationships from individuals to institutions. Neuroscience research on trust has advanced swiftly since 2001. While quantitative reviews, meta-analyses, and theoretical frameworks have effectively synthesized trust neuroscience research, bibliometric analysis remains underutilized. Our bibliometric analysis aimed to provide a comprehensive overview of trust neuroscience's current state and future directions by examining its historical development, key contributors, geographic distribution, methodological paradigms, influential works, thematic trends, and overall impact. This field has been characterized by the input of a few key contributors through international collaboration, with significant contributions from the U.S., China, the Netherlands, and Germany. Research predominantly utilizes the trust game and fMRI, with a rising focus on neural networks, general trust, and differentiating behavioral from attitudinal trust. Integrating insights from psychology, economics, and sociology, this interdisciplinary field holds promise for advancing our understanding of trust through a neurobiological lens. In conclusion, our bibliographic literature review provides valuable insights and guidance for scholars, spotlighting potential avenues for further investigation in this fast-growing field.
