Claim LD09-SL-C20 (v1.0)

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.
