A new research paper highlights significant instability in the ethical stances of large language models when presented with moral dilemmas. The study found that models, particularly smaller open-weight ones, often reverse their judgments based on how a question is phrased, such as switching from a prescription to a prohibition. Commercial models also exhibit substantial shifts, indicating that their ethical decision-making is not robust to framing variations. The researchers propose a new metric, the Negation Sensitivity Index (NSI), to better measure this stability, arguing that models prone to such flips are unreliable for high-stakes decisions. AI
