Abstract

The Generative Pre-trained Transformer(GPT) models, renowned for generating human-like text, occasionally produce “hallucinations” - outputs that diverge from human expectations. Current mitigation strategies for these GPT hallucinations largely rely on algorithmic automation, thereby overlooking the complexities of human judgment and cultural influence, particularly in fact interpretation. Addressing this issue, we have introduced a Culturally Sensitive Test that integrates language subjectivity, cultural nuances, and GPT idiosyncrasies. We have applied this test to five GPT models—OpenAI’s ChatGPT-3.5 and ChatGPT-4, Google’s Bard, Perplexity AI and TruthGPT - evaluating their responses to 70 questions across seven categories designed to provoke hallucinations. The evaluated models demonstrated varying performance, with controversial topics, those lacking clear scientific consensus and the brain teasers proving more susceptible to GPT hallucinations. Our study has paved the way for a nuanced assessment of GPT hallucinations.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Only 6 of the 23 surveyed benchmark studies were peer-reviewed at the time of this article.

    “Our review also found that only 6 of the 23 surveyed benchmark studies ( [7], [10], [31], [39], [44], [52]) were peerreviewed at the time of this article, reflecting the early-stage nature of research in this domain.”
  • The PromptBench benchmark demonstrated that LLMs were not robust to adversarial prompts, highlighting a significant gap in evaluating models' performance in real-world, context-specific scenarios.

    “PromptBench [7]: The study demonstrated that LLMs were not robust to adversarial prompts, highlighting a significant gap in evaluating models' performance in real-world, context-specific scenarios.”
  • The PromptBench benchmark acknowledged the challenge of discerning genuine reasoning from technical optimization in LLMs, indicating that it primarily evaluated models based on their ability to follow instructions and generate outputs without deeply investigating whether these outputs resulted from true understanding or merely optimization strategies.

  • The PromptBench benchmark did not establish a clear criterion for balancing helpfulness and harmlessness in adversarial prompt evaluation, focusing instead on robustness of LLMs against adversarial prompts without directly addressing how these models balance being helpful and avoiding harmful outputs in real-world scenarios.

  • PromptBench encountered difficulties in efficiently scaling their benchmark framework across various large language models, indicating substantial technical challenges in installation and scalability.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
