Agreed that it shouldn't be hard to do that, but I expect that people will often continue to do what they find intrinsically motivating, or what they're good at, even if it's not overall a good idea. If this article can be believed, a senior researcher said that they work on capabilities because "the prospect of discovery is too sweet".

Comment by Nisan on Confusions re: Higher-Level Game Theory · 2021-07-02T17:49:03.979Z · LW · GW

I feel excited about this framework! Several thoughts:

I especially like the metathreat hierarchy. It makes sense because if you completely curry it, each agent sees the foe's action, policy, metapolicy, etc., which are all generically independent pieces of information. But it gets weird when an agent sees an action that's not compatible with the foe's policy.

You hinted briefly at using hemicontinuous maps of sets instead of or in addition to probability distributions, and I think that's a big part of what makes this framework exciting. Maybe if one takes a bilimit of Scott domains or whatever, you can have an agent that can be understood simultaneously on multiple levels, and so evade commitment races. I haven't thought much about that.

I think you're right that the epiphenomenal utility functions are not good. I still think using reflective oracles is a good idea. I wonder if the power of Kakutani fixed points (magical reflective reasoning) can be combined with the power of Kleene fixed points (iteratively refining commitments).

Consider the following game: At any time , you may say "stop!", in which case you'll get the lottery that resolves to an outcome you value at with probability , and to an outcome you value at with probability . If you don't say "stop!" in that time period, we set .

Let's say at every instant in you can decide to either say "stop!" or to wait a little longer. (A dubious assumption, as it lets you make infinitely many decisions in finite time.) Then you'll naturally wait until and get a payoff of . It would have been better for you to say "stop!" at , in which case you'd get .

You can similarly argue that it's irrational for your utility to be discontinuous in the amount of wine in your glass: Otherwise you'll let the waiter fill up your glass and then be disappointed the instant it's full.

Comment by Nisan on The Homunculus Problem · 2021-05-28T19:28:01.372Z · LW · GW

Here's a fun and pointless way one could rescue the homunculus model: There's an infinite regress of homunculi, each of which sees a reconstructed image. As you pass up the chain of homunculi, the shadow gets increasingly attenuated, approaching but never reaching complete invisibility. Then we identify "you" with a suitable limit of the homunculi, and what you see is the entire sequence of images under some equivalence relation which "forgets" how similar A and B were early in the sequence, but "remembers" the presence of the shadow.

Comment by Nisan on The Homunculus Problem · 2021-05-28T19:06:45.603Z · LW · GW

The homunculus model says that all visual perception factors through an image constructed in the brain. One should be able to reconstruct this image by asking a subject to compare the brightness of pairs of checkerboard squares. A simplistic story about the optical illusion is that the brain detects the shadow and then adjusts the brightness of the squares in the constructed image to exactly compensate for the shadow, so the image depicts the checkerboard's inferred intrinsic optical properties. Such an image would have no shadow, and since that's all the homunculus sees, the homunculus wouldn't perceive a shadow.

That story is not quite right, though. Looking at the picture, the black squares in the shadow do seem darker than the dark squares outside the shadow, and similarly for the white squares. I think if you reconstructed the virtual image using the above procedure you'd get an image with an attenuated shadow. Maybe with some more work you could prove that the subject sees a strong shadow, not an attenuated one, and thereby rescue Abram's argument.

Edit: Sorry, misread your comment. I think the homunculus theory is that in the real image, the shadow is "plainly visible", but the reconstructed image in the brain adjusts the squares so that the shadow is no longer present, or is weaker. Of course, this raises the question of what it means to say the shadow is "plainly visible"...

Comment by Nisan on The Homunculus Problem · 2021-05-27T23:29:33.753Z · LW · GW

This is the sort of problem Dennett's Consciousness Explained addresses. I wish I could summarize it here, but I don't remember it well enough.

It uses the heterophenomenological method, which means you take a dataset of earnest utterances like "the shadow appears darker than the rest of the image" and "B appears brighter than A", and come up with a model of perception/cognition to explain the utterances. In practice, as you point out, homunculus models won't explain the data. Instead the model will say that different cognitive faculties will have access to different pieces of information at different times.

Comment by Nisan on The Argument For Spoilers · 2021-05-22T20:30:14.045Z · LW · GW

Very interesting. I would guess that to learn in the presence of spoilers, you'd need not only a good model of how you think, but also a way of updating the way you think according to the model's recommendations. And I'd guess this is easiest in domains where your object-level thinking is deliberate rather than intuitive, which would explain why the flashcard task would be hardest for you.

When I read about a new math concept, I eventually get the sense that my understanding of it is "fake", and I get "real" understanding by playing with the concept and getting surprised by its behavior. I assumed the surprise was essential for real understanding, but maybe it's sufficient to track which thoughts are "real" vs. "fake" and replace the latter with the former.

Comment by Nisan on Challenge: know everything that the best go bot knows about go · 2021-05-11T10:05:42.256Z · LW · GW

Or maybe it means we train the professional in the principles and heuristics that the bot knows. The question is if we can compress the bot's knowledge into, say, a 1-year training program for professionals.

There are reasons to be optimistic: We can discard information that isn't knowledge (lossy compression). And we can teach the professional in human concepts (lossless compression).

Comment by Nisan on Challenge: know everything that the best go bot knows about go · 2021-05-11T05:44:58.846Z · LW · GW

This sounds like a great goal, if you mean "know" in a lazy sense; I'm imagining a question-answering system that will correctly explain any game, move, position, or principle as the bot understands it. I don't believe I could know all at once everything that a good bot knows about go. That's too much knowledge.

The assistant could have a private key generated by the developer, held in a trusted execution environment. The assistant could invoke a procedure in the trusted environment that dumps the assistant's state and cryptographically signs it. It would be up to the assistant to make a commitment in such a way that it's possible to prove that a program with that state will never try to break the commitment. Then to trust the assistant you just have to trust the datacenter administrator not to tamper with the hardware, and to trust the developer not to leak the private key.

Yep, that is a good question and I'm glad you're asking it!

I don't know the answer. One part of it is whether the assistant is able and willing to interact with me in a way that is compatible with how I want to grow as a person.

Another part of the question is whether people in general want to become more prosocial or more cunning, or whatever. Or if they even have coherent desires around this.

Another part is whether it's possible for the assistant to follow instructions while also helping me reach my personal growth goals. I feel like there's some wiggle room there. What if, after I asked whether I'd be worse off if the government collapsed, the assistant had said "Remember when we talked about how you'd like to get better at thinking through the consequences of your actions? What do you think would happen if the government collapsed, and how would that affect people?"

Comment by Nisan on April 15, 2040 · 2021-05-05T06:28:01.552Z · LW · GW

Yeah, I would be very nervous about making an exception to my assistant's corrigibility. Ultimately, it would be prudent to be able to make some hard commitments after thinking very long and carefully about how to do that. In the meantime, here are a couple corrigibility-preserving commitment mechanisms off the top of my head:

  • Escrow: Put resources in a dumb incorrigible box that releases them under certain conditions.
  • The AI can incorrigibly make very short-lived commitments during atomic actions (like making a purchase).

Are these enough to maintain competitiveness?

Comment by Nisan on April 15, 2040 · 2021-05-04T23:18:51.231Z · LW · GW

I'd believe the claim if I thought that alignment was easy enough that AI products that pass internal product review and which don't immediately trigger lawsuits would be aligned enough to not end the world through alignment failure. But I don't think that's the case, unfortunately.

It seems like we'll have to put special effort into both single/single alignment and multi/single "alignment", because the free market might not give it to us.

Comment by Nisan on Some AI research areas and their relevance to existential safety · 2020-11-19T08:52:12.290Z · LW · GW

I'd like more discussion of the claim that alignment research is unhelpful-at-best for existential safety because of it accelerating deployment. It seems to me that alignment research has a couple paths to positive impact which might balance the risk:

  1. Tech companies will be incentivized to deploy AI with slipshod alignment, which might then take actions that no one wants and which pose existential risk. (Concretely, I'm thinking of out with a whimper and out with a bang scenarios.) But the existence of better alignment techniques might legitimize governance demands, i.e. demands that tech companies don't make products that do things that literally no one wants.

  2. Single/single alignment might be a prerequisite to certain computational social choice solutions. E.g., once we know how to build an agent that "does what [human] wants", we can then build an agent that "helps [human 1] and [human 2] draw up incomplete contracts for mutual benefit subject to the constraints in the [policy] written by [human 3]". And slipshod alignment might not be enough for this application.

"If you have two assets with the same per-share price, and asset A's value per share has a higher variance than asset B's value per share, then asset A's per-share value must have a higher expectation than asset B's per-share value."

I guess I was using "cost" to mean "price" and "return" to mean "discounted value or earnings or profit".

(I haven't read any of the literature on deception you cite, so this is my unimformed opinion.)

I don't think there's any propositional content at all in these sender-receiver games. As far as the P.redator is concerned, the signal means "I want to eat you" and the P.rey wants to be eaten.

If the environment were somewhat richer, the agents would model each other as agents, and they'd have a shared understanding of the meaning of the signals, and then I'd think we'd have a better shot of understanding deception.

Comment by Nisan on Self-sacrifice is a scarce resource · 2020-07-20T02:15:08.449Z · LW · GW

Like, if you’re in a crashing airplane with Eliezer Yudkowsky and Scott Alexander (or substitute your morally important figures of choice) and there are only two parachutes, then sure, there’s probably a good argument to be made for letting them have the parachutes.

This reminds me of something that happened when I joined the Bay Area rationalist community. A number of us were hanging out and decided to pile in a car to go somewhere, I don't remember where. Unfortunately there were more people than seatbelts. The group decided that one of us, who was widely recognized as an Important High-Impact Person, would definitely get a seatbelt; I ended up without a seatbelt.

I now regret going on that car ride. Not because of the danger; it was a short drive and traffic was light. But the self-signaling was unhealthy. I should have stayed behind, to demonstrate to myself that my safety is important. I needed to tell myself "the world will lose something precious if I die, and I have a duty to protect myself, just as these people are protecting the Important High-Impact Person".

Everyone involved in this story has grown a lot since then (me included!) and I don't have any hard feelings. I bring it up because offhand comments or jokes about sacrificing one's life for an Important High-Impact Person sound a bit off to me; they possibly reveal an unhealthy attitude towards self-sacrifice.

(If someone actually does find themselves in a situation where they must give their life to save another, I won't judge their choice.)

Comment by Nisan on Classifying games like the Prisoner's Dilemma · 2020-07-13T04:20:44.205Z · LW · GW

Von Neumann and Morgenstern also classify the two-player games, but they get only two games, up to equivalence. The reason is they assume the players get to negotiate beforehand. The only properties that matter for this are:

  • The maximin value , which represents each player's best alternative to negotiated agreement (BATNA).

  • The maximum total utility .

There are two cases:

  1. The inessential case, . This includes the Abundant Commons with . No player has any incentive to negotiate, because the BATNA is Pareto-optimal.

  2. The essential case, . This includes all other games in the OP.

It might seem strange that VNM consider, say, Cake Eating to be equivalent to Prisoner's Dilemma. But in the VNM framework, Player 1 can threaten not to eat cake in order to extract a side payment from Player 2, and this is equivalent to threatening to defect.

I also found your paper about the Kripke semantics of PTE. I'll want to give this one a careful read.

You might be interested in: Robust Cooperation in the Prisoner's Dilemma (Barasz et al. 2014), which kind of extends Tennenholtz's program equilibrium.

Ah, thank you! I have now read the post, and I didn't find it hazardous either.

More info on the content or severity of the neuropsychological and evocation infohazards would be welcome. (The WWI warning is helpful; I didn't see that the first time.)

Examples of specific evocation hazards:

  • Images of gore
  • Graphic descriptions of violence
  • Flashing lights / epilepsy trigger

Examples of specific neuropsychological hazards:

  • Glowing descriptions of bad role models
  • Suicide baiting

I know which of these hazards I'm especially susceptible to and which I'm not.

I appreciate that Hivewired thought to put these warnings in. But I'm kind of astounded that enough readers plowed through the warnings and read the post (with the expectation that they would be harmed thereby?) to cause it to be promoted.
