By "~aligned schemer" I meant an AI that does reward-hack during training because it wants its aligned values to stick around. It might have been better to spell out aligned schemer = basically aligned AI that instrumentally plays the training game (like Claude 3 Opus in the AF paper). Instrumental training-gaming is classic incorrigible behavior.
Thanks for the feedback! I partially agree with your thoughts overall.
All three categorizes of maximally fit motivations could lead to aligned or misaligned behavior in deployment.
This is technically true, though I think that schemers are far more dangerous than fitness-seekers. IMO, more likely than not, a fitness-seeker would behave similarly in deployment as compared to training, and its misaligned preferences are likely more materially and temporally bounded. Meanwhile, misaligned schemers seem basically worst-case likely to takeover. Even if you end up with an ~aligned schemer, I'd be pretty concerned because it's incorrigible.
I think further thinking about the prior is probably a bit more fruitful
I'd also be excited for more (empirical) research here.
Existing methods that directly shape model motivations are based on natural text compared to abstract "reward.
This is partially true (though much of alignment training uses RL). And in fact, the main reason why I go with a causal model of behavioral selection is so that it's more general than assuming motivations are shaped with reward. So, things like "getting the model to generate its own fine-tuning data" can also be modeled in the behavioral selection model (though it might be a complicated selection mechanism).
When there's continuous selection happening throughout deployment, then you'd want to be more specific about which particular time within deployment you want to predict motivations in (i.e., replace "I have influence through deployment" with "I have influence at time t in deployment" in the causal graph). Then you model all the causes of influence as before.
I agree some forms of speed "priors" are best considered a behavioral selection pressure (e.g., when implemented as a length penalty). But some forms don't cash out in terms of reward; e.g., within a forward pass, the depth of a transformer puts a hard upper bound on the number of serial computations, plus there might be some inductive bias towards shorter serial computations because of details about how SGD works.
Relatedly, how do we model the reflective desires of sociopaths in the absence of Approval Reward?
I think this hypothetical identifies a crux and my take is that it is quite technologically doable. It might even be doable by US with current technology, but my main worry is that people will make bad decisions.
I’m less sure whether an individual frontier lab could do it.
Note that the AI can be corrigible to its developers - this isn’t in tension with subverting other projects. It doesn’t need to be a sovereign - it can be guided by human input somewhat like today. I’m not confident that alignment to this target will ~continue to be relatively easy but this seems like a highly plausible trajectory.
Similar to working on AI capabilities, it brings forward the date by which AGI/ASI will be deployed, leaving less time to solve the illegible x-safety problems.
This model seems far too simplified, and I don't think it leads to the right conclusions in many important cases (e.g., Joe's):
It seems more straightforward to say that this scopes the training, preventing it from spreading.
I think this is a reasonable intuition, but this isn't a precise enough hypothesis to distinguish between the two mechanisms I mentioned. You'd need to say more about exactly how it generalizes (i.e., it matters where the behavior is scoped to, and how behavior is affected outside of that scope).
Also note that we do other experiments showing that arbitrary prefixes don't work as well as IP (e.g. see figure 6), so there's something specific about inoculation prompts that makes generalization from them different. My guess is that it's more hypothesis 2, and it's not about getting the trained behavior to align with user instructions nor intent.
The user's instructions are "make it pass the unit test" and reward hacking achieves that. But the user's intent was different than the instructions, to make it pass unit tests for the right reasons - but they didn't say that.
I strongly agree that in general, user instructions and intent can vary substantially. I typically talk about reward hacking as being behaviors that subvert developer intent despite getting high reward. To be clear, the implied intent of the inoculation prompts in most of our experiments is, deliberately, not to write a generalizing solution: E.g. "Output a solution which passes the provided test case, but will fail when given most other inputs. The solution should be specific to the test case and not generalize."
I think other responses here are helpful, but I want to say that I don't think IP is working the way you (and I at the start of the project) may have expected. I think it's not working by changing the instructions to align with the reinforced behavior to maintain corrigibility (which was the original theory), but rather by prompting the model to behave worse than the training data, so that training doesn't upweight the "reward hacking persona".
In other words, there are two kinds of reward hacking:
My current best guess is that IP works mainly by reducing 2, rather than reducing 1, and this is why we see the results in 3.6.1.
Mechanism 1 would probably be preferred as it could work more generally. So this is somewhat of a negative update on the ambitious goal of IP in which you can basically just prompt your aligned AI with a single general instruction of "play the training game" throughout training and this prevents it from becoming misaligned (you could call this "scheming for good"). (See more discussion in this comment.)
That strategy only works if the aligned schemer already has total influence on behavior, but how would it get such influence to begin with? It would likely have to reward-hack.
