Another project I am excited about but probably am not going to get to for a while:
Investigating the possibility of a "steganographic snowball". The basic case for hope in CoT authenticity is something like "even if the AI wants to deceive us, if we start off with strong CoT authenticity, then unless it's smart enough to (within a single forward pass) invent a steganographic protocol too good for us to detect, then we can pin it down and it can't ever secure a hidden channel to think misaligned thoughts in". If it weren't for this argument, I would be much less excited about trying to prevent an AI from thinking certain thoughts using CoT oversight, since you would have to directly fight the intelligence of the AI to do so. But if it can't deploy its full intelligence to reasoning about how to escape, then we're better off.
The concern for this angle is as follows:
I have some basic ideas for ways to measure these properties, and if all four show up positive, I would consider that significant evidence that a "steganographic snowball" is going to happen. That would mean that if your AI has any tendency to hide its thoughts from you, you won't be able to stop it forever. More specifically, you'll have to fight off the full intelligence of your AI if you want to prevent it from securing the amount of hidden channel bandwidth it wants.
There's room for retreat to a "snowball would take a long time and we can extract work in the meantime" position, but that seems like a serious concession.
Thanks to Paul Colognese for brainstorming this stuff with me.
A key dynamic here is that catching the AI doing this sort of steganography might be very useful, more useful than just naively training against this.
TBC, it's by no means obvious we can catch the AI this solidly (or capitalize on this that much), but I this sort of consideration does change my view of the situation a decent amount.
One way to think about catching dynamics is that there could be a snowball which goes in the opposite direction. For example:
Hey, thanks for the comment! Agree that this argument is good and important. The thing I'd want to investigate to deal with this is basically "in a small hidden channel, does cognition degrade or just slow down".
If cognition degrades, then a small hidden channel would lead to poor attempts at steganography, which we could catch and suppress, preventing a snowball.
If cognition instead just slows down, then if the AI is smart enough to come up with steganography protocols too good for us to detect, it might successfully secure more bandwidth on its first try, starting a snowball.
Even in the slowdown case, there are fallback hopes like "it's slow enough for us to extract work and predictably stop the episode before the snowball starts" or "we can obscure how good our steganography detection is"
I'm confused about EDT and Smoking Lesion. The canonical argument says:
1) CDT will smoke, because smoking can't cause you to have the lesion or have cancer
2) EDT will not smoke, because people who smoke tend to have the lesion, and tend to have cancer.
I'm confused about 2), and specifically about "people who smoke tend to have the lesion". Say I live in a country where everybody follows EDT. Then nobody smokes, and there is no correlation between smoking and having the lesion. Seems like the "people who smoke tend to have the lesion" is pumping a misleading intuition. Maybe mortals who make probabilistic decisions and smoke are then more likely to have the lesion. But it's not true that EDT'ers who smoke tend to have the lesion, because EDT'ers never smoke.
Seems like EDT contains a conflict between "model your actions as probabilistic and so informative about lesion status" versus "model your actions as deterministic because you perfectly follow EDT and so not informative about lesion status".
Aha wait I think I un-confused myself in the process of writing this. If we suppose that having the lesion guarantees you'll smoke, then having the lesion must force you to not be an EDT'er, because EDT'ers never smoke. So the argument kind of has to be phrased in terms of "people who smoke" instead of "EDT'ers who smoke", which sounds misleading at first, like it's tricking you with the wrong reference class for the correlation. But actually it's essential, because "EDT'ers who smoke" is a contradiction, and "people who smoke" roughly translates to "decision theories which smoke". With a deterministic decision theory you can't take action counterfactuals without a contradiction, so you have to counterfact on your whole decision theory instead.
Neat :)
A project I've been sitting on that I'm probably not going to get to for a while:
Improving on Automatic Circuit Discovery and Edge Attribution Patching by modifying them to run on algorithms that can detect complete boolean circuits. As it stands, both effectively use wire-by-wire patching, which when run on any nontrivial boolean circuits can only detect small subgraphs.
It's a bit unclear how useful this will be, because:
But I think it'll be a good project to bang out for the experience, I'm curious what the results will be compared to ACDC/EAP.
This project started out as an ARENA capstone in collaboration with Carl Guo.
