For what it's worth, I was just learning about the basics of MIRI's research when this came out, and reading it made me less convinced of the value of MIRI's research agenda. That's not necessarily a major problem, since the expected change in belief after encountering a given post should be 0, and I already had a lot of trust in MIRI. However, I found this post by Jessica Taylor vastly clearer and more persuasive (it was written before "Rocket Alignment", but I read "Rocket Alignment" first). In particular, I would expect AI researchers to be much more competent than the portrayal of spaceplane engineers in the post, and it wasn't clear to me why the analogy should be strong Bayesian evidence for MIRI being correct.

FWIW you can bet on some of these on PredictIt -- for example, Predictit assigns only a 47% chance Trump will win in 2020.

Based on the quote from Jessica Taylor, it seems like the FDT agents are trying to maximize their long-term share of the population, rather than their absolute payoffs in a single generation? If I understand the model correctly, that means the FDT agents should try to maximize the ratio of FDT payoff : 9-bot payoff (to maximize the ratio of FDT:9-bot in the next generation). The algebra then shows that they should refuse to submit to 9-bots once the population of FDT agents gets high enough (Wolfram|Alpha link), without needing to drop the random encounters assumption.


It still seems like CDT agents would behave the same way given the same goals, though?

Yeah, I was implicitly assuming that initiating a successor agent would force Omega to update its predictions about the new agent (and put the $1m in the box). As you say, that's actually not very relevant, because it's a property of a specific decision problem rather than CDT or son-of-CDT.

(I apologize in advance if this is too far afield of the intended purpose of this post)

How does the claim that "group agents require membranes" interact with the widespread support for dramatically reducing or eliminating restrictions to immigration ("open borders" for short) within the EA/LW community? I can think of several possibilities, but I'm not sure which is true:

  • There actually isn't much support for open borders
  • Open borders supporters believe that "group agents require membranes" is a reasonable generaliation, but borders are not a relevant kind of "membrane", or nations are not "group agents" in the relevant sense
  • The people who support open borders generally aren't the same people who are thinking about group agency at all
  • Open borders supporters have thought about group agency and concluded that "group agents require membranes" is not a reasonable generalization
  • Open borders supporters believe that there is no need for nations to have group agency
  • Something else I haven't thought of

Context: I have an intuition that reduced/eliminated immigration restrictions reduce global coordination, and this post helped me crystallize it (if nations have less group agency, it's harder to coordinate)

After thinking about it some more, I don't think this is true.

A concrete example: Let's say there's a CDT paperclip maximizer in an environment with Newcomb-like problems that's deciding between 3 options.

1. Don't hand control to any successor

2. Hand off control to a "LDT about correlations formed after 7am, CDT about correlations formed before 7am" successor

3. Hand off control to a LDT successor.

My understanding is that the CDT agent would take the choice that causes the highest number of paperclips to be created (in expectation). If both successors are aligned with the CDT agent, I would expect the CDT agent to choose option #3. The LDT successor agent would be able to gain more resources (and thus create more paperclips) than the other two possible agents, when faced with a Newcomb-like problem with correlations formed before the succession time. The CDT agent can cause this outcome to happen if and only if it chooses option #3.

I'm not at all sure that son-of-CDT resembles any known logical decision theory, but I don't see why it would resemble "LDT about correlations formed after 7am, CDT about correlations formed before 7am".


Edit: I agree that a CDT agent will never agree to precommit to acting like a LDT agent for correlations that have already been created, but I don't think that determines what kind of successor agent they would choose to create.

That makes sense to me, but unfortunately I'm no closer to understanding the quoted passage. Some specific confusions:

  • What's the link between death rate and time preference? My best guess is that declining life expectancy implies scarcity, but I also don't get....
  • the link between scarcity and time preference? My best guess is that high time preference means people don't put the work in to ensure sufficient future productive capacity, but that doesn't help me understand the quote so I think I'm missing something.
  • I get why emergency mobilization increases time preference, but not why high time preference is strong evidence of emergency mobilization (as opposed to other possible explanations)

Can someone explain/point me to useful resources to understand the idea of time preference as expresed in this post? In particular, I'm struggling to understand these sentences:

This suggests that near the center time preference has increased to the point where we’re creating scarcity faster than we’re alleviating it, while at the periphery scarcity is still actually being alleviated because there’s enough scarcity to go around, or perhaps marginal areas do not suffer so much from total mobilization.

I also don't understand why having an internal rate of return of 10% is evidence that we're in an emergency state of mobilization (relative to the hypothesis that managers are poorly incentivized to do long-term planning for other reasons).

I think quantitative easing is an example (if I understood the post correctly, which I'm not sure about). By buying up bonds, the government is putting more dollars into the economy, which reduces the "amount of stuff produced per dollar", thus creating scarcity (in other words, QE increases aggregate demand). To alleviate this pressure, people make more stuff in order to meet the excess demand (i.e. unemployment rates go down). Forcing the unemployment rate down is the same as "requiring almost everyone to do things"

Comment by liam-donovan on Can corrigibility be learned safely? · 2019-11-03T17:31:25.428Z · score: 1 (1 votes) · LW · GW

I understand that, but I don't see why #2 is likely to be achievable. Corrigibility seems very similar to Wei Dai's translation example, so it seems like there could be many deceptive actions that humans would intuitively recognize as not corrigible, but which would fool an early-stage LBO tree into assigning a high reward. This seems like it would be a clear example of "giving a behaviour a high reward because it is bad". Unfortunately I can't think of any good examples, so my intuition may simply be mistaken.

Incidentally, it seems like Ought could feasibly test whether meta-execution is sufficient to ensure corrigibility; for example, a malicious expert could recommend deceptive/influence-seizing actions to an agent in a simulated environment, and the meta-execution tree would have to detect every deceptive action without any contextual knowledge . Are there any plans to do this?

That makes sense; I hadn't thought of the possibility that a security failure in the HBO tree might be acceptable in this context. OTOH, if there's an input that corrupts the HBO tree, isn't it possible that the corrupted tree could output a supposed "LBO overseer" that embeds the malicious input and corrupts us when we try to verify it? If the HBO tree is insecure, it seems like a manual process that verifies its output must be insecure as well.

How do you ensure that property #3 is satisfied in the early stages of the amplification process? Since no agent in the tree will have context, and the entire system isn't very powerful yet, it seems like there could easily be inputs that would naively generate a high reward "by being bad", which the overseer couldn't detect.

Why is it desirable for the inquiry to turn up a representative sample of unpopular beliefs?

If the conclusion of the research turns out to be "here is a representative sample of unpopular LW beliefs: <a set of beliefs that doesn't include anything too reactionary/politically controversial>", that would be a dishonest & unfortunate conclusion.

My current best-guess answer for what "HCH + annotated functional programming" and no indirection is:

Instead of initializing the tree with the generic question "what should the agent do next", you initialize the tree with the specific question you want an answer for. In the context of IDA, I think (??) this would be a question sampled from the distribution of questions you want the IDA agent to be able to answer well.

Is it fair to say the HCH + AFP part mainly achieves capability amplification, and the indirection part mainly achieves security amplification?

Edit: apparently I somehow asked the original question under a different account name that I've never used before? In case anyone finds this weird/confusing: both Liam Donovans are the same person, but this is the account I normally use.

Huh, I thought that all amplification/distillation procedures were intended as a way to approximate HCH, which is itself a tree. Can you not meaningfully discuss "this amplification procedure is like an n-depth approximation of HCH at step x", for any amplification procedure?

For example, the internal structure of the distilled agent described in Christiano's paper is unlikely to look anything like a tree. However, my (potentially incorrect?) impression is that the agent's capabilities at step x are identical to an HCH tree of depth x if the underlying learning system is arbitrarily capable.
