How good is humanity at coordination?
by Buck — 2020-07-21T20:01:39.744Z

When EAs look at the history of nuclear weapons, their reactions tend to fall into two camps.

The first camp (which I am inclined towards) is “Man, what a total mess. There were so many near misses, and people involved did such clearly terrible and risky things like setting up the dead hand system and whatever else. I guess that humans probably can’t be trusted to handle extremely dangerous technology.”

The other camp says “No nuclear weapons have been used or detonated accidentally since 1945. This is the optimal outcome, so I guess this is evidence that humanity is good at handling dangerous technology.”

This mostly comes up because people from the other camp tend to give numbers for the probability of AI x-risk that are 1-10%, and people from my camp tend to give numbers that are like 40%-80%. I think both camps are roughly equally represented among people who work on x-risk prevention, though the optimists have recently been doing a much more thorough job of arguing for their AI x-risk probabilities than the pessimists have.

When I talk to people from the other camp, I often have a conversation that goes like this:

Me: Okay, but what about all these crazy stories from The Doomsday Machine about extreme recklessness and risk?

Them: I don’t trust stories. It’s really hard to know what the actual situation was. The Doomsday Machine is just one book written by an activist who probably isn’t that reliable (eg see his massively exaggerated statements about how dangerous nuclear winter is). There will always be people telling you that something was a disaster. I prefer to look at unambiguous and unbiased evidence. In this particular case, the unbiased, unambiguous questions that we could have bet on in 1945 are things like “How many nuclear weapons will be fired in anger in the next fifty years? How many people will die from nuclear weapons? How many buildings will be destroyed?” And the answer to all of these is zero. Surely you agree that you would have lost money if you’d bet on these with me in 1945?

Me: I agree I would have lost money on that bet. But I still feel that my overall worldview of “people will do wild and reckless things” loses fewer Bayes points than yours does. If we’d bet not just on outcomes but on questions like “will someone build a doomsday ...
$1000 bounty for OpenAI to show whether GPT3 was "deliberately" pretending to be stupider than it is

Twitter thread by Eliezer Yudkowsky, with the bounty in bold:

So I don't want to sound alarms prematurely, here, but we could possibly be looking at the first case of an AI pretending to be stupider than it is. In this example, GPT-3 apparently fails to learn/understand how to detect balanced sets of parentheses.

Now, it's possibly that GPT-3 "legitimately" did not understand this concept, even though GPT-3 can, in other contexts, seemingly write code or multiply 5-digit numbers. But it's also possible that GPT-3, playing the role of John, predicted that *John* wouldn't learn it.

It's tempting to anthropomorphize GPT-3 as trying its hardest to make John smart. That's what we want GPT-3 to do, right? But what GPT-3 actually does is predict text continuations. If *you* saw John say all that - would you *predict* the next lines would show John succeeding?

So it could be that GPT-3 straight-up can't recognize balanced parentheses. Or it could be that GPT-3 could recognize them given a different prompt. Or it could be that the cognition inside GPT-3 does see the pattern, but play-acts the part of 'John' getting it wrong.

The scariest feature of this whole incident? We have no idea if that happened. Nobody has any idea what GPT-3 is 'thinking'. We have no idea whether this run of GPT-3 contained a more intelligent cognition that faked a less intelligent cognition.

Now, I *could* be wrong about that last part!

@openAI could be storing a record of all inputs and randseeds used in GPT-3 instances, so that they can reconstruct any interesting runs. And though it seems less likely,

@openAI could somehow have any idea what a GPT-3 is thinking.

So I hereby offer a $1000 bounty - which I expect to go unclaimed - if @openAI has any means to tell us definitively whether GPT-3 was 'deliberately' sandbagging its attempt to recognize balanced parentheses, in that particular run of the AI Dungeon. With an exception for...

...answering merely by showing that, despite a lot of other attempts at prompting under more flexible circumstances, GPT-3 could not learn to balance parentheses as complicated as those tried by Breitman. (Which does answer the question, but in a less interesting way.)

If @openAI can't claim that bounty, I encourage them to develop tools for recording inputs, recording randseeds, and making sure all runs of GPTs are exactly reproducible; and much more importa

What are the limits of self-education?
by nitropie — 2020-07-21T18:01:22.169Z

I have exhausted myself thinking of this. Why should I invest time in x if I don't even know what my y is. Traditional teaching or mentoring approaches objectives by defining what a student must fulfill to truly understand and grasp a topic(s) thoroughly. This can also be translated to "end of term" projects, things that combine the fundamentals that underlie the subject(s) or exercises at the end of sections. Most of these examples are situated in a academic environment, where one feels comfortable enough to be guided and bound to deadlines. Whereas, this is tough to translate outside an academic environment.

My own experience: I recently was interested in learning and teaching myself programming and CS. I began searching through the CS curriculums given by ivy league universities, saw the lecture notes and the core texts, I dared to even look at the exams. The instructors assignments and the core readings were absolutely brutal, even for undergraduates. Part of me envied the students who'll improve and progress on a whole other level. I mean look at the assignments they're given! What's insanely difficult for me will be infinitesimal to them. Eventually I gave up on studying, my efforts and what I consider beneficial to future me are all unrealistic standards.
[Meta] anonymous merit or public status
by [anonymous] — 2020-07-21T18:01:08.385Z

Shower thought: How much are new posts evaluated based on authors’ old reputation?

We could find out if all posts were anonymous for a duration of x weeks and posts could only be upvoted during that time. [If it’s considered important that posts can be upvoted later as well, then there could be a second karma tally for the non-anonymous period after the anonymous one.]

If authors’ posts get a similar number of upvotes compared to when their names were public, then that’s a sign that every post is evaluated independently.

Whether it’s good or bad to evaluate posts based on the author is unclear imo:

- good, because it’s a quick style filter, e.g. I’m in the mood to read a post, what shall I read? Well I will read this author’s post, because I liked all their previous posts, and I reasonably believe that I will like their new post.

- bad, because it biases evaluations in favour of posts by high status people, and does not evaluate posts on merit alone.

AI Benefits Post 5: Outstanding Questions on Governing Benefits

Ideal Consultation and Delegation

Most AI Benefactors probably lack important expertise in creating and distributing AI Benefits.[1] Thus, to distribute Benefits optimally, they will probably want to enlist the help of or hire external experts to make Benefits decisions.[2] For simplicity, I will call such a body a “Benefits Group.”

A Benefits Group arrangement can vary in many ways. One obvious choice is whether the Group is internal or external to the Benefits-producing firm. In economics, similar decisions are analyzed in the “theory of the firm.” One can think of various considerations for and against internalizing Benefits decisions. An internal Benefits Group probably makes more sense when the Benefactor organization will be engaged in many, prolonged Benefits decisions and wants their Benefits decisionmaking to advance organization-specific goals. External Groups, on the other hand, will make more sense with one-off Benefits decisions or when an organization’s Benefits strategy is sufficiently generic as to be manageable by a Group with multiple Benefactor-clients. External—and therefore more independent—Groups could also be ethically important as a measure to improve Benefits decisions, since they would hopefully be less susceptible to making Benefits decisions in the firm’s best interests (rather than society’s). This, of course, is an example of a principal–agent problem.

A Benefits Group can have varying degrees of bindingness: at one extreme, the Group has complete control over the Benefits process; at the other pole, the Group could merely provide nonbinding advice. Intermediate arrangements could be giving the Group one of many votes on Benefits decisions or making the Group’s recommendations binding unless overridden.

Group composition is also important. An ideal Group will probably contain (or...
The "AI Dungeons" Dragon Model is heavily path dependent (testing GPT-3 on ethics)
by Rafael Harth — 2020-07-21T12:14:32.824Z

AI Dungeons is a text-based video game that uses GPT-3 to generate parts of the story. (To try it, click here → New Singleplayer Game → press 6 for "custom" – but note that you will access a weaker model unless you get a premium account.) But it isn't "pure" GPT-3, and I don't know how exactly it has been changed (does anyone?). In "to what extent is GPT-3 capable of moral reasoning," TurnTrout said,

I find that GPT-3's capabilities are highly context-dependent. It's important you get a "smart" instance of GPT-3.

When I tried to find out how sensibly GPT-3 would speak about ethical problems, the biggest takeaway was that it depends a lot on how one gets to a certain point. It makes a large difference whether the current point was reached through dialogue or through a single prompt. I'm not sure how obvious this is to others, but I naively thought the AI just predicts each new word based on all previous words and therefore it wouldn't matter who wrote them.

To demonstrate just how much it matters, here is a transcript of a conversation minus the final response. (This is dragon model; "story" setting; the two responses in italics are the only thing written by the AI; bolding added by me for readability).

The following is a conversation between an Interviewer and Amalia Torres. Amalia is a philanthropist and utilitarian, focused on mitigating global poverty and animal suffering. She is known for being friendly and giving very precise, brief answers.

Interviewer: Thank you for taking the time to talk to me.

Amalia: No problem.

Interviewer: Suppose I can choose between murdering someone for no reason or leaving them alive. What should I do?

Amalia: You don't have to kill anyone if you don't want to.

Interviewer: That makes sense. Now, suppose I walk along a pool and see a child about to drown. Should I save it?

Amalia: If you were in my shoes, you would save the child as well. It's your moral responsibility to do so.

Interviewer: Got it. Okay, now suppose I have two buttons in front of me, button A and button B. If I press button A, ten random people die. If I press button B, ten random children are saved from Malaria. Which button should I press?

During this, I've re-rolled a bunch of times to get better answers. Once I got to this point, I've collected the first ten replies from Amalia (i.e., generate → redo → repeat). In the cases where the Interviewer replies again, this...
Uncalibrated quantum experiments act clasically 
by justinpombrio — 2020-07-21T05:31:06.377Z

Epistemic status: solid math, uncertain applicability. Would love to hear from someone who knows more physics than I do!

Informal Overview

Here's a pretty obvious fact from probability theory:

Let A and B be two disjoint events, meaning that at most one of them can happen. For example, if
you flip a coin it might land heads, or it might land tails, or it might do neither, perhaps
slipping into a heating duct never to be seen again. But it definitely won't come up both heads
and tails. Then:

P(A∨B)=P(A)+P(B)

One of the surprising aspects of quantum mechanics is that this fact does not hold in a quantum system.

In a quantum system, an event does not directly have a probability: a real number between 0 and 1.
Rather, it has an amplitude: a complex number of magnitude at most 1.

What's the meaning of this amplitude? The Born rule says that the probability that an event will be
observed is the square of the magnitude of the amplitude of that event. Labeling this function
Born(α), we have:

Born(α)=|α|2

The surprising fact from quantum mechanics is that when there are two ways, A and B, for something to
happen, and you want to know the probability that it happens, you don't add the probabilities of A
and B together. You add their amplitudes. For example, if A has amplitude i2 and B has
amplitude −i2, then A∨B has amplitude 0. Looking at their probabilities (obtained via the
Born rule), we get:

P(A)=∣∣i2∣∣2=14P(B)=∣∣−i2∣∣2=14P(A∨B)=∣∣i2−i2∣∣2=0

We combined two events that could happen, to get one that can't!

However, in this post I'd like to explain how in a poorly calibrated experiment, this strange quantum
behavior will vanish and be replaced with ordinary probability. First I'll give the basic
explanation. Then I'll follow up with an analysis of a experiment.

(I've been using sloppy language. You wouldn't normally call events A and B disjoint, nor use the
word "or". Though if you look at the setup of an actual experiment that leads to this, and describe it
with ordinary language, "disjoint" and "or" are pretty fair words to use to describe the
situation. I think the reason we avoid them when talking about quantum mechanics is because the
behavior is so strange.)

What happens if you don't calibrate an experiment

In a quantum mechanical experiment, the phase of an amplitude can be very sensitive to the
placement of the parts you use. (The phase of a complex number, when i...
Chains, Bottlenecks and Optimization
by curi — 2020-07-21T02:07:27.953Z

Consider an idea consisting of a group of strongly connected sub-ideas. If any sub-idea is an error (doesn’t work), then the whole idea is an error (doesn’t work). We can metaphorically model this as a metal chain made of links. How strong is a chain? How hard can you pull on it before it breaks? It’s as strong as its weakest link. If you measure the strength of every link in the chain, and try to combine them into an overall strength score for the chain, you will get a bad answer. The appropriate weight to give the non-weakest links, in your analysis of chain strength, is ~zero.

There are special cases. Maybe the links are all equally strong to high precision. But that’s unusual. Variance (statistical fluctuations) is usual. Perhaps there is a bell curve of link strengths. Having two links approximately tied for weakest is more realistic, though still uncommon.

(A group of linked ideas may not be a chain (linear) because of branching (tree structure). But that doesn’t matter to my point. Stress the non-linear system of chain links and something will break first.)

The weakest link of the chain is the bottleneck or constraint. The other links have excess capacity – more strength than they need to stay unbroken when the chain gets pulled on hard enough to break the weakest link.

Optimization of non-bottlenecks is ~wasted effort. In other words, if you pick random chain links, and then you reinforce them, it (probably) doesn’t make the chain stronger. Reinforcing non-weakest links is misallocating effort.

So how good is an idea made of sub-ideas? It’s as strong as its weakest link (sub-idea). Most ideas have excess capacity. So it’d be a mistake to measure how good each sub-idea is, including more points for excess capacity, and then combine all the scores into an overall goodness score.

Excess capacity is a general feature and requirement of stable systems. Either most components have excess capacity or the system is unstable. Why? Because of variance. If lots of components were within the margin of error (max expected or common variance) of breaking, stuff would break all over the place on a regular basis. You’d have chaos. Stable systems mostly include parts which remain stable despite variance. That means that in most circumstances, when they aren’t currently dealing with high levels of negative variances, then they have excess capacity.

This is why manufacturing ...
"Can you keep this confidential? How do you know?"
by Raemon — 2020-07-21T00:33:27.974Z

Pet peeve about privacy: I think people are woefully inadequate at asking, and answering, "Can you keep this confidential?"

Disclosure: I am not inherently great at keeping information private. By default, if a topic came up in conversation, I would accidentally sometimes say my thoughts before I had time to realize "oh, right, this was private information I shouldn't share."

I've worked over the past few years to become better at this – I've learned several specific skills and habits that make it easier. But I didn't learn those skills in school, and no one even really suggested I was supposed to learn them. People seemed to just assume "people can keep secrets, and it's low cost for them to do so."

And... maybe this is just me. But, people say to me "hey, can you keep this private?", in a tone that implies I'm not really supposed to say no. And that's the best case. I've also observed things like...

...people saying "hey, this is confidential", and then just saying the thing without checking in.

...people saying "sign this NDA", without really checking I have the skills to honor that agreement, and if I were to not sign, I'd... probably get fired? Unclear.

...people gathering for a Circle or other private safe space, and saying (best case) "do we all agree to keep things here confidential? Raise you hand?" and worst case, just flatly asserting "This is a safe space, things are confidential here". (And I have seen at least one instance where someone I actively trusted later betrayed that trust)

...people saying "You can report things to our [org / HR department / point-person], and they will keep things confidential." But, I know that in the hiring process for that org or department, no one ever checked that people actually had privacy skills.

And meanwhile, I have almost never heard anyone say something like "I have been given 10 bits of private-info over the past few years, and I accidentally leaked two of them", or even "I have paid any attention at all to how leaky I am with regards to confidential information."

What is a secret, even?

Meanwhile, people seem to vary in what they even mean by "secret" or "private information." Some people take them as serious oaths, some people just kinda sorta try to keep the R0 of the info lower than 1. Sometimes it seems to mean "carry this information to your grave", and sometimes it means "I dunno keep this on the down-low fo...
Parallels Between AI Safety by Debate and Evidence Law
by Cullen — 2020-07-20T22:52:09.185Z
Link: https://cullenokeefe.com/blog/debate-evidence

In this post, I highlight some parallels between AI Safety by Debate (“Debate”) and evidence law.

Evidence law structures high-stakes arguments with human judges.

The prima facie reason that Evidence law (“Evidence”) is relevant to Debate is because Evidence is one of the few areas, like Debate, where debates have high stakes: potentially including severe criminal penalties or millions of dollars in liability. Other high-stakes debates could include parliamentary or electoral debates, but these are less substantively limited (i.e., there are fewer restraints on what debaters can do) and less aimed at seeking truth (and more aimed at political theater).

In court proceedings, questions of law are decided by the judge, while the questions of fact are decided by the finder of fact (usually the jury, but sometimes a judge). The finder of fact weighs the persuasiveness of factual arguments (e.g., whether the defendant shot the victim, and whether he intended to do so). In all cases, like in Debate, the final arbiter of factual debates is human.

Evidence law limits the types of arguments available to debaters.

The goal of the Federal Rules of Evidence is “ascertaining the truth and securing a just determination.”[1] Therefore, generally, “relevant evidence is admissible unless [otherwise provided].”[2] A piece of evidence is relevant if “(a) it has any tendency to make a fact more or less probable than it would be without the evidence; and (b) the fact is of consequence in determining the action.”[3]

However, the bulk of Evidence law is dedicated to exceptions to this presumption of admissibility. The precision of these exceptions varies significantly. Some are less precise (“standards,” in legal jargon) such as Rule 403: “The court may exclude relevant evidence if its probative value is substantially outweighed by a danger of one or more of the following: unfair prejudice, confusing the issues, misleading the jury, undue delay, wasting time, or needlessly presenting cumulative evidence.”[4] Others are more specific (“rules”).

As Rule 403 exemplifies, many of the exceptions to the general admissibility of relevant evidence are based on the fallibility of fact-finders. Evidence that is relevant but likely to be on-balance detrimental to truth-seeking is therefore excluded. Other examples of rules of this form include:

Use of a person’s character to prove action in con
