What happened

Ars Technica retracted an article after purportedly AI-generated text was presented as direct quotations from a source who disputed having said them. The editor-in-chief reportedly acknowledged a standards failure and said the publication was not consistent with Ars policy on AI-generated material, and apologized to readers and to matplotlib maintainer Scott Shambaugh. An author reportedly later said he had inadvertently used an AI-paraphrased version of the source text as quotes.

Laws that address this harm

Risk entries describing this failure mode

Entries from the MIT AI Risk Repository coded to subdomain 3.1.

  • Pursuing Consistent Context

    "LLMs have been demonstrated to pursue consistent context [129]–[132], which may lead to erroneous generation when the prefixes contain false information. Typical examples include sycophancy [129], [130], false demonstra...

  • Defective Decoding Process

    In general, LLMs employ the Transformer architecture [32] and generate content in an autoregressive manner, where the prediction of the next token is conditioned on the previously generated token sequence. Such a scheme...

  • Noisy Training Data

    "Another important source of hallucinations is the noise in training data, which introduces errors in the knowledge stored in model parameters [111]–[113]. Generally, the training data inherently harbors misinformation....
