A recent study conducted by researchers at Columbia University has shed light on the limitations faced by artificial intelligence (AI) models in discerning between nonsensical and natural language. This finding highlights the need for caution when considering the integration of these models into legal or medical settings.
The study involved testing nine different AI models by presenting them with pairs of sentences and asking which ones were likely to be used in everyday speech. To compare the AI models’ responses with human judgement, the researchers also asked 100 individuals to make the same assessment. The results showed significant differences between the AI models and human responses.
Although sophisticated models like GPT-2, an earlier version of the model behind the popular chatbot ChatGPT, generally aligned with human judgement, the simpler models performed less consistently. However, it is worth noting that all AI models made errors in distinguishing meaningful sentences from gibberish.
Professor Christopher Baldassano, one of the authors of the report, emphasized that every model exhibited blind spots, labeling some sentences as meaningful when human participants considered them to be nonsense. This raises concerns about relying on AI systems for important decision-making at the current stage of development.
While the authors acknowledge the potential of AI models to enhance human productivity, they caution against premature substitution of human decision-making in domains such as law, medicine, or student evaluation. Exploitation of these blind spots is a plausible risk, undermining the reliability of AI models in practical applications.
The emergence of AI models, exemplified by the release of ChatGPT, has sparked significant interest and potential applications in various fields. However, this study underscores the importance of addressing the existing challenges before fully integrating these models into critical decision-making processes.

The study showed that AI models still struggle to distinguish between nonsense and natural language.
No, while more sophisticated models like GPT-2 aligned with human judgement, simpler models had greater difficulty in accurately identifying meaningful sentences.
No, the researchers advised against premature substitution of human decision-making in crucial domains such as law, medicine, or student evaluation due to the limitations and blind spots exhibited by AI models.
The possibility of intentional exploitation of AI models’ blind spots was identified as a significant concern, potentially undermining their reliability in real-world applications.
The study highlights the need for further development and refinement of AI models before fully entrusting them with critical decision-making tasks.
