Claim LD09-SL-C12 (v1.0)
Re-analysing a published set of five brainstorming experiments, the authors found ChatGPT-aided idea sets less diverse than comparison sets in all five (significantly in four), and lower on all of their alternative diversity metrics, with 37 of 45 comparisons statistically significant; in one task 6% of ChatGPT-only ideas were unique against 100% of human-only ideas.
Research opportunities this claim motivates
What this claim leaves open for research. Each is a hypothesis about a gap, not a finding.
- In science, is it the wording that converges or the ideas?Idea sets were less diverse on most alternative measures in a brainstorming re-analysis.
