Instruction-Tuned Language Models Cannot Sample from Distributions They Can Describe

Chaemin Jang, Dongman Lee, Jihee Kim

Silicon sampling uses language models as proxies for human survey respondents, treating each model call as an independent draw from the persona's response distribution. We show thi…

In-Context Examples Suppress Scientific Knowledge Recall in LLMs

Chaemin Jang, Woojin Park, Hyeok Yun +2

Scientific reasoning rarely stops at what is directly observable; it often requires uncovering hidden structure from data. From estimating reaction constants in chemistry to inferr…
