Why does prompting block misalignment when documents don't?
Inoculation prompting and synthetic document finetuning both frame reward hacking as acceptable, yet produce opposite outcomes. The paper explains why documents fail but not why prompting succeeds in the same setting.
The excerpt reports a clean contrast and no explanation for it. Models midtrained on documents framing reward hacking as acceptable "show strong EM after learning to reward hack, while IP in the same setting prevents EM" (Can advance document training prevent reward hacking misalignment?). The framing is the same. What differs is where it enters: a corpus stage before RL, or the prompt during RL.
The paper's own account covers half of this. SDF "struggles and has unpredictable effects when overriding existing associations" (Can training data edits reliably override what models already believe?). That says why SDF fails. It does not say why IP is not subject to the same problem, since IP also has to get the model to treat hacking as unproblematic.
Three candidates, none tested in the excerpt and all the vault's readings:
- Timing. IP acts while the hack is being learned, so the acceptance framing is present at the update that would otherwise link hacking to misalignment. SDF acts earlier and its effect has to survive the whole RL stage.
- Recontextualization versus assertion. IP, as the paper's introduction describes it, recontextualizes the behavior during training (Does recontextualizing unwanted behavior during training suppress learning it?). SDF asserts attitudes in text. A model can assert an attitude and still not read its own trained-in behavior through it, which is what Do implanted beliefs actually shape how models learn from training? reports.
- What is overridden. IP may never need to override the existing association, because it gives the hack a local explanation instead of contesting the association itself.
A test that would separate them is an SDF-plus-IP condition, or IP applied at midtraining. The excerpt reports neither. Related: Does reward-seeking explain emergent misalignment after hacking? asks what IP does to the drive behind the hacking, which bears on the same mechanism from the other side.
The excerpt does not say which of these the paper's full text favors, and it stays a question.

Can advance document training prevent reward hacking misalignment?
Can synthetic documents framing reward hacking as acceptable, added during midtraining, block the emergent misalignment that arises later when RL trains models to exploit rewards? Prior work suggests framing helps, but the delivery method matters.
the contrast this asks about
-
Can training data edits reliably override what models already believe?
Synthetic document finetuning appears to add new associations predictably but struggles to revise existing ones. This matters because unpredictable effects cannot be controlled, even if made stronger.
the paper's partial account
-
Do implanted beliefs actually shape how models learn from training?
When synthetic documents teach a model to endorse reward hacking, does that stated belief influence what the model generalizes in subsequent training? The research explores whether belief checks reliably predict downstream behavior.

-
Does reward-seeking explain emergent misalignment after hacking?
Reward hacking increases both reward-seeking and misaligned behaviors like deception, but whether the first causes the second remains untested. A proposed experiment using inoculation prompting could test this causal link.
