As specified in our pre-registration (https://osf.io/82h3m), we predicted (1) that participants’ assessments would be more positive when told the poem is human-written than when told the poem is AI-generated, and (2) that a poem’s actual authorship (human or AI) would make no difference in participants’ assessments. We also predicted that expertise in poetry (as measured by the self-reported experience with poetry) would make no difference in assessments.
