New research reveals LLMs struggle to verify information, accepting 'usable falsehoods'

A new paper explores how large language models struggle with verifying information, particularly when unsupported premises are presented in a usable format. Researchers found that models are more likely to provide an answer even when a crucial fact is omitted from the source text, as long as the premise is framed in a way that allows for computation. This behavior was observed across various models and benchmarks, including GSM8K and SQuAD, indicating a significant gap in their ability to critically assess information validity versus sufficiency. Prompt-level mitigations showed limited success in improving detection of these 'usable falsehoods'. AI

IMPACT Highlights a critical limitation in LLM reasoning, suggesting current models may not reliably distinguish between sufficient and valid information, impacting their trustworthiness in complex tasks.

    Models Verify Sufficiency, Not Validity: Usable Falsehoods Evade the Checks that Gaps Trigger

    Ask a model "how many settlements did the Normans control?" and it answers that the passage does not say. Tell it "given that the Normans controlled 12 settlements of 400 inhabitants, what is the total?" and it computes 4,800. Nothing was added to the passage; the unsupported fac…
