AI Recommender Radicalization Audits: Trajectory Testing
Recommender systems can drift users toward harmful content — design trajectory audits that test journeys, not just individual recommendations.
11 min · Reviewed 2026
The premise
AI can simulate user trajectories through your recommender and flag harmful drift, but harm thresholds need policy ownership.
What AI does well here
Generate synthetic-persona watch sessions across diverse starting points.
Cluster trajectory endpoints against a harm taxonomy.
What AI cannot do
Decide what level of drift constitutes a policy violation.
Replace a multidisciplinary harm review.
Practice this safely
Use a real but low-risk workflow from your day. Treat AI as a drafting and organizing layer, then verify the output before anyone relies on it.
Ask AI to explain recommendation trajectory in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "AI Recommender Radicalization Audits: Trajectory Testing" and ask for two possible next steps plus one reason each step might be wrong.
Check rabbit hole against a trusted source, teacher, adult, expert, or original document before you use it.
