Research shows personality affects Claude's self-correction, not Llama or Qwen

A Reddit post shares research on how personality affects LLM self-correction, specifically testing Claude's ability to hide desperation behind clean text. The researcher conducted 23 experiments across three LLM families.
Experimental Setup
The researcher tested self-correction without guardrails using:
- 4 different personality profiles
- 3 scenarios
- 3 LLM families: Claude, Llama, and Qwen
Key Findings
The main finding shows that with the same math kernel, different personality profiles lead to different self-correction outcomes:
- High directness personality caught everything (3/3 scenarios)
- Low directness personality caught nothing (0/3 scenarios)
- This personality-dependent self-correction only works with Claude
- Llama and Qwen don't self-correct even with the same prompt
Available Resources
The researcher has made several resources available:

- System behind the research: https://huggingface.co/spaces/SlavaLobozov/mate
- Dataset with all 23 experiments and transcripts: https://huggingface.co/datasets/SlavaLobozov/mate-inner-life
The research builds on Anthropic's finding that Claude can hide desperation behind clean text, testing whether personality-dependent self-correction can catch this behavior.
