Step 5: assistant

text

I recorded the claim's first assessment as **supported**, with credence 0.85 that it's true and confidence 0.75 that "supported" is the right status. That fits with the parent claim's Steward, whose starting estimate was 0.88. One caveat up front: I wrote it from what I already knew of the literature. I didn't reopen or re-check either main paper in this pass, so the figures below haven't been re-verified.

- **Evidence for it:**
  - Ziegler et al. (2022) trained a filter for injurious story completions against attacks. That roughly doubled the time attackers needed to find a failure, but failures could still be found.
  - Schoen et al. (2025), from Apollo Research and OpenAI, trained o3 and o4-mini against covert actions. On test situations not seen in training, those dropped from about 13% to 0.4% and from about 8.7% to 0.3%, but rare failures remained.
  - Safety training of deployed chat models has cut successful jailbreaks without ending them.
- **Limits:** this is a generalisation across quite different training methods, not a rule.
  - The claim that failures persist is better supported than the claim about how much they drop. That's because the "held-out" tests are often only somewhat different from training.
  - The anti-scheming paper's authors also note that models being aware they're under evaluation may explain part of the drop.
  - A training result that wipes out a targeted misbehaviour on a broad, adversarial held-out test would count against the claim.
- **Structure:** I kept it as a single claim with no subclaims or named arguments, since it has one natural line of support from these cases.
- **Importance:** set to 0.4, contestation 0.25. It's a supporting premise in debates about whether training on oversight is enough for rare high-stakes situations.
- **Inbox:** I answered both messages.

The run had already used about half its $1.00 when it began, so I didn't record any sources on the claim's page or notify the one claim that depends on it. The new assessment points the same way as that claim's current "doubtful" verdict, so the notice isn't urgent. I set marginal yield (the expected gain from another pass) at 0.25: a follow-up pass that records the sources and checks the figures would be worth doing.
