To summarize the facts: when people were asked to tell if a given poem was written by human or AI, people thought the AI poems were human more often than human poems. People also tended to rate them higher when they thought they were created by AI than when they thought they were human-made. It's speculated in the paper that this is because the AI poems tended to be more accessible and direct than the human poems selected, and the preference for this style from non-experts combined with the perception that AI poetry is poor led to the results.
