Toward a Model of Interpersonal Trust Drawn from Neuroscience, Psychology, and Economics
Abstract
Trust pervades nearly every social aspect of our daily lives, and its disruption is a significant factor in mental illness. Research in the field of neuroeconomics has gained a deeper understanding of the neuropsychoeconomic (NPE) underpinnings of trust by combining complementary methodologies from neuroscience, psychology, and economics. However, a coherent model of trust that integrates separate findings under a conceptual framework is still lacking. Here, we sketch out an integrative NPE model that explains how the interactions of psychoeconomic components engage domain-general large-scale brain networks in shaping trust behavior over time. We also point out caveats of current research approaches and outline open questions that can help guide future transdisciplinary investigations for a better understanding of the neuropsychology of trust.

The neural circuits of trust and loneliness are largely intertwined and share neuroanatomical pathways via the amygdala, anterior insula, medial prefrontal cortex, nucleus accumbens, and temporoparietal junction.
“the neural circuits of trust and loneliness are largely intertwined and share neuroanatomical pathways via the amygdala, the anterior insula (AI), the medial prefrontal cortex (mPFC), the nucleus accumbens (NAcc), and the temporoparietal junction (TPJ).[ 6 , 14 , 15 , 16 , 17 ]”

High-lonely participants did not differ from low-lonely participants in game conditions per se but showed a blunted differentiation between trust- and risk-related trials in the left amygdala, left anterior insula, and right nucleus accumbens.
“Results revealed that HL participants did not differ from LL participants in game conditions per se (all p cor > 0.072) but rather showed a blunted differentiation (i.e., smaller activity increase) between trust‐ and risk‐related trials in brain regions associated with the evaluation of trustworthiness, risk of betrayal, and reward anticipation.[ 15 ]”

The main analyses of fMRI data focused on independently defined brain regions (ROIs) known to be involved in motivational, affective, and cognitive processes during the trust game.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
