Subtly wrong advice misaligns models more than obviously wrong advice - Replication.

LessWrongAnalysis or commentary·
AI brief

Researchers fine-tuned 12 open-weight models on correct, obviously incorrect and subtly incorrect advice across 8 narrow domains, and report that subtly incorrect data produces more emergent misalignment than obviously incorrect data, replicating an OpenAI result.

Why it matters: It suggests that data quality problems which are hard to spot can misalign models more than clearly wrong data.
