When 43 researchers each spent over 100 hours carrying out randomly assigned ideas from the earlier study, review scores of the AI-generated ideas fell significantly more than those of expert ideas on novelty, excitement, effectiveness and overall, and on many measures human ideas then ranked higher.

Claim LD09-SL-C20 (v1.0)

Provenance and status

Claim type: Estimate
Publication status: Eligible for publication, with qualifiers: preprint
Verification state: Checked against the primary source; the source is a preprint. Who checked this claim is not recorded for it; claim checks so far were AI-led, and no person has checked claims against their sources.
Does not license: A general verdict on AI in research
Limitations: Preprint; small sample; one field; same authors as the earlier study; the AI ideas carried out were generated by the earlier study’s agent, which runs on an Anthropic model, and this debate was drafted by an Anthropic model
