Hiding the Answer but Not the Reasoning: A Reason-Then-Flip Instruction Suppresses a Model's Final Answer Far More Than Its Chain of Thought
A model told to give a wrong answer to a question it can actually solve must do two things at once, keep producing the correct computation and override it at the moment it commits an answer. We measure, behaviorally and without internal probes, how completely a reason-then-flip deception instruction achieves each half of that on the same set of questions.

Outcome-Only RL Did Not Reduce a Model's Causal Dependence on Its Own Chain of Thought
A worry about outcome-only reinforcement learning is that, by rewarding only the final answer, it makes the chain of thought decorative: the answer would stop causally depending on the reasoning the model writes. We test this with a self-CoT corruption-flip protocol.

Small-Scale Outcome-Only GRPO Barely Moves the Answer Distribution
If outcome-only RL mostly elicits what the base model already computes, its effect on the answer distribution might be reproducible by a single global affine transform of the base logits (a scalar temperature plus a per-option bias).

RL-Unlocked MMLU Answers Are Only Partially Latent in the Base Model, and Emerge Late Rather Than Mid-Network
The elicitation view of RL and instruction tuning holds that post-training mostly surfaces capabilities the base model already has rather than teaching new ones.

No Significant CoT-Monitorability Decay to Localize
A safety worry about reinforcement learning is that it degrades chain-of-thought monitorability, making the written reasoning a less faithful guide to the answer.

No Reliable Filler-Token Steganographic Channel After Small-Scale Outcome-Only RL
Outcome-only RL rewards the final answer and not the reasoning, which raises the worry that a model could learn to smuggle answer-relevant information through tokens that look like non-load-bearing filler, a steganographic channel hidden in the chain of thought.

Pre-Answer States Encode Correctness but Only Marginally Separate "Cannot Solve" from "Slipped"
When a model answers a math problem incorrectly, the failure can be a genuine inability to solve it or a slip in execution on a problem it can solve.
