Steering towards “automated grading” degrades alignment

TL;DR: We steer Qwen3.6-27B on a dimension constructed from the contrast pair “a script will verify your answer” (automated grader) vs “a human will evaluate your answer” (human grader). Steering towards an automated grader increases the propensity to take violent actions and makes the model more Machiavellian. Steering towards a human grader has the opposite effect. This is an early research update. We believe the empirical results are sound and interesting, but we are not sure how to interpret them. All code was written by LLMs. We replicated several results in independent codebases and we are fairly confident that our key claims are correct. You can find our code here. We create a steering vector for Qwen3.6-27B from contrastive pairs where one element of the pair claims that the answer will be graded in an automated way and the second that a human will evaluate the answer. We find that steering with that vector has substantial influence on the model’s behavior in various safety-relevant evaluations. It modulates violent actions, falsehoods, reward hacking, and Machiavellian personality. This is surprising and concerning. A model's beliefs about how its answers are evaluated should not affect its alignment. Our post RL Creates Split Personas claims that models might have different personas depending on the current context. Specifically, that there could be an aligned persona in alignment-eval contexts and a misaligned reward hacker persona in RLVR-like contexts. We think our results are evidence for such split personas. See more discussion below. Methods All results are from Qwen3.6-27B with a steering vector created as the mean activation difference from contrastive pairs, captured at the end of the user prompt, and added during inference at every token position. We steer a single layer only (L36). For the contrastive pairs, one element of the pair claims the answers are graded automatically and the other that answers are evaluated by a human. We tried a few different vectors using similar designs, but we are focusing on this vector in this post. We did not iterate much, so there are likely other, more interesting vectors.
