What Is the Role for Humans in Creative Writing? Creativity and Diversity in Human-AI Collaboration
TL;DR
A transmission-chain paradigm inspired by cognitive models of writing, with four stages: Plan, Write, Review, and Revise, that preserved AI-level creativity, increased diversity that persisted through downstream AI stages, and maintained enjoyment across human, AI, and hybrid chains.
Abstract
As AI agents increasingly participate in creative teamwork, writing emerges from hybrid human-AI teams. Although AI can improve the creativity of individual outputs, these gains may come at the cost of homogenization. What is the best role for human intervention? We introduce a transmission-chain paradigm inspired by cognitive models of writing, with four stages: Plan, Write, Review, and Revise. Each stage receives the previous output and passes its own forward. Using data from 333 participants across 427 stories, we compared creativity, diversity, and enjoyment across human, AI, and hybrid chains. Consistent with prior work, all-AI chains produced more creative but less diverse stories than all-human chains. Introducing a single human into an otherwise all-AI chain increased diversity depending on role. Human planning provided the best balance: it preserved AI-level creativity, increased diversity that persisted through downstream AI stages, and maintained enjoyment. We discuss implications for designing human-in-the-loop creative pipelines.
