読者はChatGPTの物語を人間の作家より高く評価、ただしAIと明かされるまで
2,500人の参加者を対象とした研究で、読者はChatGPTの短編小説を人間が書いたものよりも質が高いと評価したものの、AI製であることが明かされると評価は急落。機械の創造性に対する強い偏見が浮き彫りになりました。
a study published in the journal judgment and decision making analyzed the reactions of 2,587 participants who read six short stories, half written by humans and half generated by chatgpt-4. when the source was blinded, ai stories received significantly higher mean scores for quality (1.54 vs 0.97) and immersion (1.42 vs 1.00) than human texts, likely because ai writing is smoother and easier to process. however, the experiments revealed a robust 'ai labeling effect': when participants were told a story was ai-generated, their ratings dropped, and when told it was human-written, ratings rose, regardless of the actual origin. furthermore, ai skeptics rated stories lower when told they were ai-generated, while ai enthusiasts rated them higher, yet no group could reliably identify the stories' origins better than chance when tested directly.
