Evidence and limits
Finding: AI assistance improved individual ratings, especially for less creative writers, while making outputs more similar to each other.
Impact: Strengthen portfolio-diversity measurement. Reject average item quality as sufficient collective value.
Boundary: Short creative-writing tasks do not establish organizational innovation effects. Next: when does repeated model assistance narrow the research or design portfolio?
Flags: one creative domain; short horizon
Record State: Catalog review recorded; not a performance endorsement
What was reviewed: Structure and relevance screened; not a full evaluation
