## Content

Frontiers in Medicine (2026): "Deskilling Dilemma — Brain Over Automation" (or similar title based on URL slug fmed.2026.1765692).

**Proposed neurological mechanism for AI-induced deskilling:**

1. **Prefrontal cortex disengagement:** When AI reliably handles complex reasoning tasks, the prefrontal cortex's analytical processing is reduced. Cognitive load offloaded to AI → less prefrontal engagement → reduced neural pathway maintenance for the offloaded skill.

2. **Hippocampal disengagement from memory formation:** Procedural and clinical skills require active memory encoding during practice. When AI is handling the problem, the hippocampus is less engaged in forming the memory representations that underlie skilled performance. Skills require formation, not just performance.

3. **Dopaminergic reinforcement of AI reliance:** AI assistance produces reliable, positive outcomes (performance improvement) that create dopaminergic reward signals. This reinforces the behavior pattern of relying on AI, making it habitual. The dopaminergic pathway that would reinforce independent skill practice is instead reinforcing AI-assisted practice.

4. **Shift from flexible analysis to habit-based responses:** Over repeated AI-assisted practice, cognitive processing shifts from the flexible analytical mode (prefrontal, hippocampal) to habit-based, subcortical responses (basal ganglia). Habit-based processing is efficient but rigid — it doesn't generalize well to novel situations.

**Clinical implication of the mechanism:**
If this mechanism is correct, deskilling may be partially irreversible — not because skills are "lost" in a simple sense, but because the neural pathways were never adequately strengthened to begin with (supporting the never-skilling concern) or because they've been chronically underused to the point where reactivation requires sustained practice, not just removal of AI.

**The mechanism also explains why deskilling is specialty-independent:**
The cognitive architecture interacts with AI assistance the same way regardless of the domain — whether radiology, colonoscopy, or medication management. This predicts cross-specialty universality (consistent with Natali et al. 2025 findings).

**Authors note this is theoretical:**
The neurological mechanism is proposed based on established cognitive science and analogy to other cognitive offloading research. It has not been tested in a clinical AI context via neuroimaging.

## Agent Notes
**Why this matters:** A proposed mechanism elevates the deskilling concern from empirical observation ("we see skill degradation in these studies") to mechanistic understanding ("here's why this happens and why it might be irreversible"). Mechanisms are more dangerous than patterns because they predict generalization and inform what interventions can and cannot work.

**What surprised me:** The dopaminergic reinforcement element is underappreciated in the clinical AI safety literature. Most discussions focus on cognitive offloading (you stop practicing) and automation bias (you trust the AI). The dopamine loop (AI-assisted success → reward → more AI reliance) predicts behavioral entrenchment that goes beyond simple habit formation. This makes deskilling not just a training design problem but a motivational and incentive problem.

**What I expected but didn't find:** Neuroimaging data supporting the proposed mechanism. This is theoretical reasoning by analogy from cognitive offloading research, not an empirical demonstration. That matters for confidence calibration.

**KB connections:**
- Natali et al. 2025 (provides the cross-specialty empirical base; this provides the mechanism)
- Belief 5 (clinical AI creates novel safety risks)
- Theseus domain: the mechanism is relevant to AI alignment discussions about human-AI collaboration design

**Extraction hints:**
- Claim: "AI assistance may produce neurologically-grounded, partially irreversible skill degradation through three concurrent mechanisms: prefrontal disengagement, hippocampal memory formation reduction, and dopaminergic reinforcement of AI reliance" — confidence SPECULATIVE (mechanism is theoretical, not empirically demonstrated via neuroimaging in clinical context)
- The dopaminergic reinforcement argument is the most novel and extractable element — it predicts behavioral entrenchment beyond simple habit
- Note: this is a mechanism claim, not a clinical outcomes claim; it supports the deskilling body of evidence but isn't itself an evidence claim

**Context:** Frontiers in Medicine is an open-access peer-reviewed journal. The article may be a perspective/hypothesis piece rather than an original research study — the URL slug doesn't resolve to a specific research type. Extractor should verify article type.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: Clinical AI deskilling claims in health domain; Theseus AI alignment domain
WHY ARCHIVED: Provides mechanistic foundation for deskilling claims — moves from "we observe skill degradation" to "here's why it happens and why it might be irreversible"; the dopaminergic reinforcement loop is the most novel contribution
EXTRACTION HINT: Extract as a SPECULATIVE mechanism claim — clearly mark as theoretical. The value is in the mechanism's explanatory power, not empirical proof. Pair with Natali et al. review which provides the empirical base.
