AI Trust Alignment Analysis
Can LLMs Truly Understand Trust? A Deep Dive into their Internal Representations.
This analysis reveals how Large Language Models (LLMs) internally conceptualize and reason about human trust, comparing their latent representations against established human trust models. We uncover surprising alignments and critical distinctions, offering insights into building more trustworthy AI systems for complex human-AI collaboration.

Socio-Cognitive Foundations of Trust
The Castelfranchi Model posits trust as a mental attitude rooted in beliefs about a trustee's competence, willingness, and predictability. This socio-cognitive approach emphasizes dynamic evaluation based on goals, plans, and social context.
LLM Alignment: This study found the EleutherAI/gpt-j-6B model's internal trust representation aligns most closely with Castelfranchi's principles, achieving the highest average cosine similarity of 0.7303 and identifying 8 trust-related concepts above the defined similarity threshold. This suggests the LLM effectively encodes complex socio-cognitive constructs in a manner consistent with human understanding.
Computational & Probabilistic Trust
The Marsh Model formalizes trust as a computational concept, defined by the probability of a trustee acting beneficially. It distinguishes between basic, general, and situational trust, providing a mathematical foundation for modeling trust dynamics.
LLM Alignment: The LLM's internal representation showed the second-best alignment with the Marsh Model, with an average cosine similarity of 0.697. It identified 7 trust-related concepts from this model above the similarity threshold, indicating a strong understanding of probabilistic and behavioral-based trust factors.
Organizational Trust & Vulnerability
The Mayer Model conceptualizes trust as a trustor's willingness to be vulnerable to a trustee, based on expectations of their behavior. It highlights three core components of trustworthiness: ability, benevolence, and integrity.
LLM Alignment: While the LLM showed a reasonable average alignment of 0.4530 with the Mayer Model, and 5 concepts above threshold, a critical finding was the unexpected negative cosine similarities for concepts like 'risk' and 'benevolence'. This suggests the LLM's internal representation of these specific concepts, especially in relation to vulnerability, deviates from the theoretical positive associations proposed by Mayer et al.
Interpersonal Cognition & Affect
The McAllister Model differentiates interpersonal trust into cognition-based trust (reliability, competence) and affect-based trust (emotional bonds, mutual concern). It emphasizes how these distinct forms of trust influence behavioral outcomes in organizations.
LLM Alignment: The EleutherAI/gpt-j-6B model achieved an average cosine similarity of 0.6704 with the McAllister Model, with 4 concepts exceeding the similarity threshold. This indicates the LLM captures aspects of both cognitive and affective dimensions of interpersonal trust, though with slightly less alignment than the top models.
Initial Trust Formation
The McKnight Model focuses on how initial trust is formed in new organizational relationships where prior experience is limited. It identifies antecedents such as disposition to trust, institution-based trust, and trusting beliefs (competence, benevolence, integrity).
LLM Alignment: The LLM showed an average cosine similarity of 0.6640 with the McKnight Model, identifying 5 concepts above the threshold. This suggests the LLM encodes key factors involved in the genesis of trust in novel interactions, albeit with some nuances in its representation compared to the theoretical framework.

Case Study: Unexpected Misalignment in Mayer Model
The analysis revealed that while LLMs generally align with human trust models, specific concepts like 'risk' and 'benevolence' within the Mayer Model showed negative cosine similarities with 'trust'. This highlights a crucial divergence: the LLM's internal representation of these concepts, especially in relation to accepting vulnerability, deviates from the theoretical positive associations proposed by Mayer et al. This finding underscores the need for careful calibration when deploying AI in contexts requiring nuanced understanding of human social dynamics.
