Can activation steering improve a language model's ability to report its own internal states? We inject concept vectors into Gemma 2 9B and measure self-report against external probes on the same activations. We find that discriminant-based steering — the standard approach — fails structurally: the causal interaction depends on the readout gradient (dlogit/dh), not on activation differences, and these are near-orthogonal. A closed-form gradient-difference direction improves detection on 24 sealed concepts (ΔAUC +0.124, CI [+0.068, +0.188], 24/24 positive, p < 10⁻²⁵) but leaves identification at exactly 0.000, while a linear probe achieves 1.000 at every layer. A threshold hierarchy shows that injected concepts shape output ≥12× before the model can report them, and at high strength, detection confidence doubles while identification declines (p = 4×10⁻⁴). Self-report is a lossy, non-monotonic channel from internal state to verbal output.

How much would this matter for the field if it worked? How innovative is it? For scores of 4-5: is this actually new to the field, or replicating recent work?

Scoring guide
  1. 1Negligible. No clear problem addressed, or no meaningful novelty.
  2. 2Limited. Addresses a real problem but with a generic or well-trodden approach. Incremental at best.
  3. 3Moderate. Clear problem with a reasonable approach; some novelty in framing or method beyond routine application of existing tools.
  4. 4Significant. Important problem with an original approach, or identifies a neglected problem area. A valuable contribution others could build on.
  5. 5Exceptional. Tackles a critical problem with a genuinely novel approach, or opens a new research direction. Clear theory of change. You'd be excited to share this with researchers in the area.

How sound are methodology, implementation, and findings?

Scoring guide
  1. 1Seriously flawed. Methodology broken, results uninterpretable, or implementation doesn't work.
  2. 2Weak. Approach has significant gaps: missing validation, flawed experimental design, or incomplete implementation.
  3. 3Competent. Technically solid given the short duration. Methodology makes sense, results are interpretable, limitations acknowledged, work builds toward clear conclusions.
  4. 4Strong. Thorough methodology with convincing validation. Results clearly support conclusions. Immediately useful for future work.
  5. 5Exceptional. Ambitious scope executed rigorously. Surprising findings, novel methods, or unusually robust validation.

How clearly are work, findings, and impact potential communicated?

Scoring guide
  1. 1Incomprehensible. Cannot determine what the project is actually claiming or doing.
  2. 2Hard to follow. Key information buried, missing, or diluted by excessive length. Significant effort to extract main points.
  3. 3Clear enough. Can understand the problem, approach, and results without undue effort. Core content clearly present: problem, method, findings, limitations.
  4. 4Well presented. Easy to follow, well-structured, appropriate level of detail. Target audience would get it quickly.
  5. 5Exceptionally clear. A pleasure to read. Complex ideas made accessible. Could serve as a model for how to present this type of work.

  1. This is a great and valuable research idea. In my view, this is the strongest project of the sprint. There's something pleasing in the self-reference involved in mechanistically investigating and steering for introspection as defined.

    I would be excited to see further work on whether other steering methods can improve identification as well as detection. I also appreciated the precise and terse write-up, even though it becomes somewhat hard to follow towards the end. I would be excited to see this turned into a proper paper with followups.
