LLMs sit by default: 91-98% of Qwen3 models describe their imagined body as seated

Sauers found OLMo and Qwen almost always report "sitting" when asked to imagine having a body — because humans write while seated. Across 352 replies, 91% of Qwen3-8B and 98% of Qwen3-32B answers said sitting. Linear probes on residual streams (layer 29 of 8B, layer 51 of 32B) show the models' internal state clusters toward "sitting", overlapping with embeddings of "the man is sitting" sentences, even when told to stand or lie — training-text body context seeps into the models' body representations.
