Current AI evaluation frameworks focus primarily on technical performance, including accuracy, robustness, reasoning ability, and policy compliance. These measures remain essential, but they are not sufficient for systems that interact directly with users through natural language. Human-facing AI systems are increasingly used as advisors, coaches, tutors, and companions. In these roles, their responses can shape how users reason, interpret emotions, form beliefs, calibrate trust, and make decisions. The relevant unit of evaluation is therefore not only the model, but the human-AI interaction. This paper introduces psychological competence as a missing dimension in AI evaluation. We define psychological competence as the capacity of a human-facing AI system to support user cognition, emotional interpretation, and behavioral decision-making in ways that are appropriate to the user, context, and purpose of the interaction. This includes interaction properties such as framing, tone, perceived authority, responsiveness, uncertainty handling, and conversational guidance. Existing evaluation approaches capture parts of this problem but rarely assess these psychological effects directly. Drawing on behavioral science and human-AI interaction research, we outline a conceptual framework for psychological competence and its core domains. Rather than proposing a specific benchmark, we define the construct, clarify its boundaries, and describe how it may be assessed through scenario-based probes, structured human evaluation, and model-assisted evaluation methods. We argue that psychological competence should become a core consideration for model providers, deploying organizations, researchers, and regulators concerned with the real-world effects of human-facing AI systems.

Psychological Competence as a Missing Dimension in AI Evaluation

Current AI evaluation frameworks are heavily focused on technical metrics like accuracy, robustness, and policy compliance. While these are necessary, they fail to account for how AI systems influence users when acting as advisors, coaches, tutors, or companions. This paper argues that because these systems shape how users think, feel, and make decisions, we must shift our focus from evaluating the model in isolation to evaluating the human-AI interaction. The authors introduce "psychological competence" as a critical, missing dimension for assessing how effectively an AI supports human cognition and behavior.

Defining Psychological Competence

The authors define psychological competence as an AI system’s ability to support user cognition, emotional interpretation, and decision-making in a way that is appropriate for the specific user, context, and purpose. This goes beyond simple information delivery. It encompasses the subtle, often overlooked properties of an interaction, such as the AI's tone, how it frames information, its perceived authority, how it handles uncertainty, and the quality of its conversational guidance.

Why Technical Metrics Are Not Enough

Existing evaluation methods often capture technical performance but rarely measure the psychological impact of an AI on its user. When an AI acts as a companion or coach, its responses can inadvertently influence a user's beliefs, trust, and emotional state. Because these systems are increasingly integrated into sensitive areas of human life, the authors argue that technical accuracy alone is an insufficient standard. The "unit of evaluation" must expand to include the entire human-AI interaction to ensure that the system's influence is beneficial and contextually appropriate.

Assessing Psychological Impact

Rather than proposing a single benchmark, the authors provide a conceptual framework to help researchers and developers integrate psychological competence into their evaluation processes. They suggest that this can be measured through three primary methods:

Scenario-based probes: Testing how a model responds to specific, psychologically sensitive situations.
Structured human evaluation: Using human feedback to assess the quality and appropriateness of the interaction.
Model-assisted evaluation: Leveraging other AI models to analyze the psychological properties of the conversation.

A Call for Industry-Wide Adoption

The authors conclude that psychological competence should become a core consideration for everyone involved in the AI lifecycle. This includes model providers, organizations deploying AI, researchers, and regulators. By prioritizing the real-world psychological effects of these systems, stakeholders can better ensure that human-facing AI acts as a supportive and effective tool rather than a source of unintended influence or confusion.
