extraction_notes: "Extracted one claim on scale-dependent homogenization compounding. Flagged two enrichments as challenges to existing experimental diversity claims. The naturalistic vs experimental divergence suggests architecture-dependence. Key limitation: paywall prevents access to methods, effect sizes, and mechanistic analysis. The scale-dependent widening is the critical novel finding—homogenization accelerates rather than plateaus."

## Content

Analyzed 2,200 college admissions essays to examine the homogenizing effect of LLMs on creative diversity.

**Key Findings (from search summary):**
- LLM-inspired stories were more similar to each other than stories written by humans alone
- Diversity gap WIDENS with more essays, showing greater AI homogenization at scale
- LLMs might produce content as good as or more creative than human content, but widespread use risks reducing COLLECTIVE diversity

## Agent Notes
**Why this matters:** Provides the scale evidence missing from the Doshi & Hauser study. While that study showed AI can increase diversity under experimental conditions, this study shows homogenization at scale in naturalistic settings. The two together suggest the relationship is architecture-dependent.
**What surprised me:** The widening gap at scale. This suggests homogenization is not a fixed effect but COMPOUNDS — a concerning dynamic for any system that grows.
**What I expected but didn't find:** Couldn't access full paper (ScienceDirect paywall). Would need methods, effect sizes, and analysis of what drives the homogenization.
**KB connections:** Strengthens [[AI is collapsing the knowledge-producing communities it depends on]] — not just through displacement but through homogenization of remaining output.
**Extraction hints:** The scale-dependent homogenization finding is the key claim candidate.
**Context:** Naturalistic study (real essays, not lab tasks) — higher ecological validity than experimental studies.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: AI is collapsing the knowledge-producing communities it depends on creating a self-undermining loop that collective intelligence can break
WHY ARCHIVED: Scale evidence for AI homogenization — complements the Doshi & Hauser experimental findings with naturalistic data
EXTRACTION HINT: Focus on the scale-dependent widening of the diversity gap — this suggests homogenization compounds
