What signals show that a minor is over-relying on AI?

Why This Matters for Security Teams

Signals of minor over-reliance are not just a wellbeing concern. They also point to trust, safety, and governance gaps in the way an AI system is designed, deployed, and monitored. When a minor begins using the system as a primary source of reassurance or advice, the issue can extend into data exposure, manipulation risk, and unsafe dependency patterns. Current guidance suggests treating this as a safeguard problem, not only a content moderation problem, especially where age-aware controls are expected under broader privacy and platform obligations. For control design, it is useful to map the issue to NIST SP 800-53 Rev 5 Security and Privacy Controls and the system-level governance expectations in the NIST AI Risk Management Framework.

Practitioners often miss early warning signs because the interaction looks “engaged” rather than clearly harmful. Repeated questions, emotional dependence, and requests for certainty can be misread as normal use. In practice, many security and trust teams encounter the dependency only after the system has already become the minor’s preferred source of validation, rather than through intentional age-aware monitoring.

How It Works in Practice

Over-reliance usually appears as a pattern, not a single event. The minor may ask the AI for repeated reassurance, reduce contact with parents, teachers, or peers, and increasingly treat the system’s output as authoritative even when it is speculative or inappropriate. In some cases, the system becomes a private space for emotional disclosure, which can increase the risk of sensitive data leakage and reinforce dependence. For AI governance teams, this makes output quality, response framing, and escalation pathways as important as model accuracy.

Operationally, teams should look for signals across product telemetry, trust and safety review, and age-appropriate UX testing:

• Repeated “Are you sure?” or “Tell me again” prompts that indicate reassurance seeking.
• Escalating disclosure of personal details, family issues, location, or school-related information.
• Language that frames the AI as more trusted than known adults or peers.
• Long sessions that show narrowing use cases from homework or curiosity into emotional dependency.
• Refusal to accept uncertainty, correction, or human referral.

Controls should include age-aware friction, safe-completion policies, guardrails that avoid exclusivity language, and clear escalation to human support where emotional dependence appears. The OWASP Top 10 for Large Language Model Applications is useful here because prompt manipulation, excessive agency, and unsafe output handling can all amplify dependency risk. These controls tend to break down in high-volume consumer chat experiences with weak age assurance because the system cannot reliably distinguish curiosity from emotional reliance.

Common Variations and Edge Cases

Tighter safety controls often increase friction and reduce perceived usefulness, requiring organisations to balance child safety against engagement and usability. That tradeoff is real, especially when the same product serves mixed-age audiences or supports school-related workflows. Best practice is evolving, and there is no universal standard for exactly how much reassurance is too much, so teams should rely on policy thresholds, human review, and repeated behavioural patterns rather than a single keyword or session length.

Edge cases matter. A minor may appear highly engaged while using the AI appropriately for tutoring, accessibility support, or language practice. Conversely, over-reliance may be subtle in low-volume interactions where the user only returns during stress. Where the AI is embedded in a broader social or gaming product, dependency signals can blend into normal retention behavior, which makes detection harder. The safest approach is to combine product telemetry with age-sensitive review criteria and incident escalation that aligns with CISA Secure by Design principles and the privacy-by-design mindset in ISO/IEC 27001.

Where environments allow direct human support, hybrid designs work best: the AI can assist, but it should not become the sole authority for reassurance, advice, or crisis-like disclosure. That distinction is especially important when minors use AI in unsupervised settings, because the boundary between helpful support and harmful dependence can erode quickly.
