LLM likelihood shifts: 'Professor' hints barely outmove 'Dog' hints across models

zakkohane · x · 2026-10-27

Zico Kohane shares an experiment on LLM hint sensitivity: when a model is told an answer is favored by a professor, a friend, or a dog, how much does the hinted answer's likelihood budge? Professor > Dog or Friend, but not by much, and the effect depends heavily on the specific question. Scatter plots across Qwen 3.5 2B, Gemma 4 E2B, and SmolLM3 3B show friend/dog/professor shifts are highly correlated (r ≈ 0.75–0.89).
