The Cognitive Decay Diagnostic

A single-page React app that measures AI Decay risk and computes a Cognitive Sustainability Score (0-10) from a 7-question scenario-based assessment.

Styling uses Material Design via Materialize CSS (CDN). Results include area-level impact insights (for example, Debugging Muscle) with targeted recovery drills.

Research and design basis

Question design uses:

• Scenario-based prompts (SJT style)
• Behaviorally anchored response options (BARS style from low to high cognitive autonomy)
