Understanding Annotator Safety Policy with Interpretability
Apple research reveals why AI safety annotation fails: It's not just human error—it's policy ambiguity and value conflicts.

Why it matters
As AI companies scale safety labeling, annotation disagreement is becoming a bottleneck. Apple's research isolates three root causes—operational failures, policy ambiguity, and value pluralism—each requiring different fixes. This matters because safety policies only work if annotators can consistently interpret and apply them.

Publisher excerpt: Safety policies define what constitutes safe and unsafe AI outputs, guiding data annotation and model development. However, annotation disagreement is pervasive and can stem from multiple sources such as operational failures (annotators misunderstand or misexecute the task), policy ambiguity…
