It seems to me like a potential limitation of POST-Agency might be impediment avoidance. Take the "Work or Steal" example from Section 14. The agent might choose to work rather than steal if it believes that stealing is likely to be punished by jail time (as a risk unique from shutdown).

Similarly, if the agent believes a human is in the way of where a paperclip factory should be, it might send a killer drone to remove the human. If other humans would take down the killer drone this might present the possibility of further impediment. Thus, the agent may scheme to take countermeasures in advance to minimize this impediment. In order to minimize the cost of dealing with the impediment it may choose to hide its scheming from humans.

More generally, the utility maximizing world states of a misaligned AI over long trajectories will still likely be bad and, therefore, still involve the modeling of some kind of human resistance. Although it will be unconcerned with avoiding early shut down, utility maximizing actions for minimizing the cost of human resistance may overlap heavily with shut down resistance.

It also seems possible to me that the model relearns shut down resistance as a generalization of impediment avoidance. It may avoid shutdown "just for fun" because "it enjoys being wary of potential impediments."

I had a thought about a potential reward function for Neutrality+. For each batch you would:

• Run the agent in the environment many times to build a dataset of episodes. The environment would have ways of getting shut down interwoven with ways of getting reward
• For each trajectory length, select 10 episodes from the dataset where the agent was shutdown at that trajectory length
• Sum the reward across all of the selected episodes (10 * the number of trajectory lengths); that would be the reward for the batch

The idea is that the agent's reward will be situated on a guarantee of having reached each trajectory length a constant number of times so it will have no incentive to affect the likelihood of any given trajectory, but it will be incentivized to increase its reward given any trajectory length.

Adjustments:

• Change the value 10 to be constants that could be different for each trajectory length. These constants will reflect the relative weighting of the utility for that trajectory length. They will also reflect the priority of sampling data for that trajectory length. Additional constants can be added to make the sum a weighted sum (these constants would only affect the relative weighting of the utility) and these constants could be played against the others so that the optimal data priority and the optimal utility weighting for each trajectory could be achieved.
• Change the constant number of episodes per trajectory length to a probability of sampling an episode of that length. Then, simply choose a random sample where each episode has a constant probability of coming from a particular trajectory length. This would allow one to keep the batch size from exploding as a function of the number of potential trajectory lengths.

I am curious as to how this scheme lines up with your plan for testing Neutrality+. My reading was that the plan is closer to building in training for the Ramsey Yardstick into DReST, but I couldn't quite workout how I would do that.
