GPT-4o aligns best with human baselines overall, while GPT-3.5 and Llama2 exhibit ~20% of moral decisions misaligned with human responses. Llama2 shows extremely low valid response rates for certain personas (conservative: 7.2%, religious: 6.0%), raising questions about the reliability of its moral decision analysis under those conditions.",
