Why does AI love writing about lighthouse keepers?
A recent study from Cornell University reveals that leading language models frequently generate stories featuring a limited set of characters and themes, particularly lighthouse keepers and fishermen. The research analyzed 20,000 stories and found that 88% included at least one of 11 specific tokens related to location, name, or profession. This pattern was confirmed through independent testing of various language models, which consistently produced similar narrative elements.
- ▪The study found that 88% of stories generated by language models featured at least one of 11 specific tokens.
- ▪The most common tokens included names like Elias and Mara, and professions such as keeper and fisherman.
- ▪Independent testing of models like ChatGPT and Claude Haiku confirmed the study's findings.
