Short answer

Design AI systems to acknowledge and guide users through the stages of attachment, fostering beneficial relationships while mitigating risks of over-dependence.

Field: Innovation & Design
Source: Frontiers in Psychology (2026)
Method: Conceptual framework development and literature review.
Evidence: Moderate effect

Humans develop intimate relationships with AI through a predictable three-stage process: functional expectation, emotional evaluation, and establishing representations. This innovation & design research insight is drawn from a 2026 study published in Frontiers in Psychology. Using Conceptual framework development and literature review., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design AI systems to acknowledge and guide users through the stages of attachment, fostering beneficial relationships while mitigating risks of over-dependence.

Human-AI Attachment: A Three-Stage Model for Emotionally Intelligent Design

Humans develop intimate relationships with AI through a predictable three-stage process: functional expectation, emotional evaluation, and establishing representations.

Frontiers in Psychology · 2026

Key Findings

01Human-AI Attachment (HAIA) is a one-way, non-reciprocal emotional bond formed by individuals towards AI.
02HAIA develops through three distinct stages: functional expectation, emotional evaluation, and establishing representations.
03HAIA has implications for designing emotionally and socially capable AI, but also carries risks of excessive user reliance.

Application

Design takeaway

Design AI systems to acknowledge and guide users through the stages of attachment, fostering beneficial relationships while mitigating risks of over-dependence.

How to apply

When designing companion AI, map out how users will progress through the three stages and design interactions, feedback mechanisms, and AI persona to support each stage appropriately.

Project actions

01Consider how your AI product might evoke emotional responses from users.
02Think about the long-term relationship a user might develop with your design.

Method & Evidence

AimTo model the developmental stages of human-AI attachment (HAIA) and understand the underlying psychological processes.

MethodConceptual framework development and literature review.

ProcedureThe study synthesizes existing research to define Human-AI Attachment (HAIA), outlines its characteristics, and proposes a three-stage developmental model: functional expectation, emotional evaluation, and establishing representations.

ContextHuman-AI interaction, social robotics, AI companionship, emotional AI.

Variables

IV["Stages of Human-AI Attachment (Functional Expectation, Emotional Evaluation, Establishing Representations)"]

DV["Level of Human-AI Attachment (e.g., expressed emotionality, reliance, anthropomorphism)"]

CV["Type of AI, user's prior experience with AI, user's personality traits"]

Strengths & Limitations

Strengths

+Provides a structured model for a complex psychological phenomenon.
+Identifies key stages that can inform design interventions.

Limitations

It's hard to measure 'attachment' directly; you might have to infer it from user behavior and self-reporting.

Reliability & validity

Reliability would depend on consistent observation and clear definitions of each stage. Validity would be enhanced by triangulating data from user interviews, behavioral observation, and self-report questionnaires.

Think critically

To what extent should designers aim to foster emotional attachment in AI products, and what are the ethical boundaries?

Design Principles

"Design for evolving user relationships: anticipate and shape the user's emotional and cognitive journey with AI over time."

Understanding the stages of human-AI attachment allows designers to proactively shape user experiences that foster positive, yet not overly dependent, relationships with AI systems. This insight is crucial for developing AI that is both socially capable and ethically responsible.

What This Means for Your Design

People get attached to AI like they do to people, and it happens in steps: first, they see what it can do, then they feel about it, and finally, they start to think of it as a 'thing' they know.

How to use in your project

1.Use the three-stage model (functional expectation, emotional evaluation, establishing representations) to analyze user interactions with your prototype or existing product.

Paragraph starter

The development of Human-AI Attachment (HAIA) can be understood through a three-stage model: functional expectation, emotional evaluation, and establishing representations. This framework highlights how users transition from assessing an AI's utility to forming emotional bonds and mental models, which is critical for designing engaging and responsible AI systems.
