Adjust classification granularity when categories either collapse distinctions needed for decisions (over-compression) or preserve distinctions never used for decisions (under-compression).

Optimal compression preserves exactly the distinctions needed for decisions - more wastes cognitive resources on irrelevant detail, less loses actionable signal.
