Study finds LLM moral rankings flip when answer order is reversed
Overview
Researchers tested five LLMs, including GPT-5.2, Gemini and DeepSeek, by asking which of two moral violations was worse.
Reversing the order of the two options changed the ranking in 26 of 30 test blocks, according to a report on X by Rohan Paul.
After averaging the results, four of the five models produced a clean, nearly identical ranking. That averaged ranking matched none of the individual test sets, the report says.
