Followup to: Inseparably Right, Sorting Pebbles Into Correct Heaps
Richard Chappell, a pro, writes:
"When Bob says "Abortion is wrong", and Sally says, "No it isn't", they are disagreeing with each other.
I don't see how Eliezer can accommodate this. On his account, what Bob asserted is true iff abortion is prohibited by the morality_Bob norms. How can Sally disagree? There's no disputing (we may suppose) that abortion is indeed prohibited by morality_Bob...
Since there is moral disagreement, whatever Eliezer purports to be analysing here, it is not morality."
The phenomena of moral disagreement, moral error, and moral progress, on terminal values, are the primary drivers behind my metaethics. Think of how simple Friendly AI would be if there were no moral disagreements, moral errors, or moral progress!
Richard claims, "There's no disputing (we may suppose) that abortion is indeed prohibited by morality_Bob."
We may not suppose, and there is disputing. Bob does not have direct, unmediated, veridical access to the output of his own morality.
I tried to describe morality as a "computation". In retrospect, I don't think this is functioning as the Word of Power that I thought I was emitting.
Let us read, for "computation", "idealized abstract dynamic"—maybe that will be a more comfortable label to apply to morality.
Even so, I would have thought it obvious that computations may be the subjects of mystery and error. Maybe it's not as obvious outside computer science?
Disagreement has two prerequisites: the possibility of agreement and the possibility of error. For two people to agree on something, there must be something they are agreeing about, a referent held in common. And it must be possible for an "error" to take place, a conflict between "P" in the map and not-P in the territory. Where these two prerequisites are present, Sally can say to Bob: "That thing we were just both talking about—you are in error about it."
Richard's objection would seem in the first place to rule out the possibility of moral error, from which he derives the impossibility of moral agreement.
So: does my metaethics rule out moral error? Is there no disputing that abortion is indeed prohibited by morality_Bob?
This is such a strange idea that I find myself wondering what the heck Richard could be thinking. My best guess is that Richard, perhaps having not read all the posts in this sequence, is taking my notion of morality_Bob to refer to a flat, static list of valuations explicitly asserted by Bob. "Abortion is wrong" would be on Bob's list, and there would be no disputing that.
But on the contrary, I conceive of morality_Bob as something that unfolds into Bob's morality—like the way one can describe in 6 states and 2 symbols a Turing machine that will write 4.640 × 101439 1s to its tape before halting.
So morality_Bob refers to a compact folded specification, and not a flat list of outputs. But still, how could Bob be wrong about the output of his own morality?
In manifold obvious and non-obvious ways:
Bob could be empirically mistaken about the state of fetuses, perhaps believing fetuses to be aware of the outside world. (Correcting this might change Bob's instrumental values but not terminal values.)
Bob could have formed his beliefs about what constituted "personhood" in the presence of confusion about the nature of consciousness, so that if Bob were fully informed about consciousness, Bob would not have been tempted to talk about "the beginning of life" or "the human kind" in order to define personhood. (This changes Bob's expressed terminal values; afterward he will state different general rules about what sort of physical things are ends in themselves.)
So those are the obvious moral errors—instrumental errors driven by empirical mistakes; and erroneous generalizations about terminal values, driven by failure to consider moral arguments that are valid but hard to find in the search space.
Then there are less obvious sources of moral error: Bob could have a list of mind-influencing considerations that he considers morally valid, and a list of other mind-influencing considerations that Bob considers morally invalid. Maybe Bob was raised a Christian and now considers that cultural influence to be invalid. But, unknown to Bob, when he weighs up his values for and against abortion, the influence of his Christian upbringing comes in and distorts his summing of value-weights. So Bob believes that the output of his current validated moral beliefs is to prohibit abortion, but actually this is a leftover of his childhood and not the output of those beliefs at all.
(Note that Robin Hanson and I seem to disagree, in a case like this, as to exactly what degree we should take Bob's word about what his morals are.)
Or Bob could believe that the word of God determines moral truth and that God has prohibited abortion in the Bible. Then Bob is making metaethical mistakes, causing his mind to malfunction in a highly general way, and add moral generalizations to his belief pool, which he would not do if veridical knowledge of the universe destroyed his current and incoherent metaethics.
Now let us turn to the disagreement between Sally and Bob.
You could suggest that Sally is saying to Bob, "Abortion is allowed by morality_Bob", but that seems a bit oversimplified; it is not psychologically or morally realistic.
If Sally and Bob were unrealistically sophisticated, they might describe their dispute as follows:
Bob: "Abortion is wrong."
Sally: "Do you think that this is something of which most humans ought to be persuadable?"
Bob: "Yes, I do. Do you think abortion is right?"
Sally: "Yes, I do. And I don't think that's because I'm a psychopath by common human standards. I think most humans would come to agree with me, if they knew the facts I knew, and heard the same moral arguments I've heard."
Bob: "I think, then, that we must have a moral disagreement: since we both believe ourselves to be a shared moral frame of reference on this issue, and yet our moral intuitions say different things to us."
Sally: "Well, it is not logically necessary that we have a genuine disagreement. We might be mistaken in believing ourselves to mean the same thing by the words right and wrong, since neither of us can introspectively report our own moral reference frames or unfold them fully."
Bob: "But if the meaning is similar up to the third decimal place, or sufficiently similar in some respects that it ought to be delivering similar answers on this particular issue, then, even if our moralities are not in-principle identical, I would not hesitate to invoke the intuitions for transpersonal morality."
Sally: "I agree. Until proven otherwise, I am inclined to talk about this question as if it is the same question unto us."
Bob: "So I say 'Abortion is wrong' without further qualification or specialization on what wrong means unto me."
Sally: "And I think that abortion is right. We have a disagreement, then, and at least one of us must be mistaken."
Bob: "Unless we're actually choosing differently because of in-principle unresolvable differences in our moral frame of reference, as if one of us were a paperclip maximizer. In that case, we would be mutually mistaken in our belief that when we talk about doing what is right, we mean the same thing by right. We would agree that we have a disagreement, but we would both be wrong."
Now, this is not exactly what most people are explicitly thinking when they engage in a moral dispute—but it is how I would cash out and naturalize their intuitions about transpersonal morality.
Richard also says, "Since there is moral disagreement..." This seems like a prime case of what I call naive philosophical realism—the belief that philosophical intuitions are direct unmediated veridical passports to philosophical truth.
It so happens that I agree that there is such a thing as moral disagreement. Tomorrow I will endeavor to justify, in fuller detail, how this statement can possibly make sense in a reductionistic natural universe. So I am not disputing this particular proposition. But I note, in passing, that Richard cannot justifiably assert the existence of moral disagreement as an irrefutable premise for discussion, though he could consider it as an apparent datum. You cannot take as irrefutable premises, things that you have not explained exactly; for then what is it that is certain to be true?
I cannot help but note the resemblance to Richard's assumption that "there's no disputing" that abortion is indeed prohibited by morality_Bob—the assumption that Bob has direct veridical unmediated access to the final unfolded output of his own morality.
Perhaps Richard means that we could suppose that abortion is indeed prohibited by morality_Bob, and allowed by morality_Sally, there being at least two possible minds for whom this would be true. Then the two minds might be mistaken about believing themselves to disagree. Actually they would simply be directed by different algorithms.
You cannot have a disagreement about which algorithm should direct your actions, without first having the same meaning of should—and no matter how you try to phrase this in terms of "what ought to direct your actions" or "right actions" or "correct heaps of pebbles", in the end you will be left with the empirical fact that it is possible to construct minds directed by any coherent utility function.
When a paperclip maximizer and a pencil maximizer do different things, they are not disagreeing about anything, they are just different optimization processes. You cannot detach should-ness from any specific criterion of should-ness and be left with a pure empty should-ness that the paperclip maximizer and pencil maximizer can be said to disagree about—unless you cover "disagreement" to include differences where two agents have nothing to say to each other.
But this would be an extreme position to take with respect to your fellow humans, and I recommend against doing so. Even a psychopath would still be in a common moral reference frame with you, if, fully informed, they would decide to take a pill that would make them non-psychopaths. If you told me that my ability to care about other people was neurologically damaged, and you offered me a pill to fix it, I would take it. Now, perhaps some psychopaths would not be persuadable in-principle to take the pill that would, by our standards, "fix" them. But I note the possibility to emphasize what an extreme statement it is to say of someone:
"We have nothing to argue about, we are only different optimization processes."
That should be reserved for paperclip maximizers, not used against humans whose arguments you don't like.

Far more extreme, I would think, to say that zero out of 6.5 billion humans are stable psychopaths.
I wonder if the distinction between 1) something implementing the same dynamic as a typical human but mistaken about what it says and 2) something implementing a completely different dynamic and not mistaken about anything, is the same as the distinction people normally make between 1) immoral and 2) amoral.
Steven: quite possibly related. I don't think they're exactly the same (the classic comic book/high fantasy "I'm evil and I know it" villain fits A2, but I'd describe him as amoral), but it's an interesting parallel.

Do non-psychopaths that given the chance would self-modify into psychopaths fall into the same moral reference frame as stable psychopaths?
My intuition is that a good deal of people would take the psychopath pill. At least if the social consequences were minimal, which is besides the point.
Frame it defensively rather than offensively and a whole heck of a lot of people would take that pill. Of course some of us would also take the pill that negates the effects of our friends taking the first pill, hehehe.

I do not eat steak, because I am uncertain of what my own morality outputs with respect to steak-eating.

The propositions I have suggested do not seem reasonable to you.
Do you imagine that there are facts about the brains of cattle which we could both learn - facts drawn from fMRI scans, or from behavioral science experiments, perhaps - which would bring us into agreement on the issue?
Eliezer: for 'better' vs 'frooter,' of course you're right.

Re: "We have nothing to argue about, we are only different optimization processes." That seems to apply in the case when a man wants to rescue copies of his genes from eternal oblivion - by convincing his mate not to abort his prospective offspring.

Eliezer: "But this would be an extreme position to take with respect to your fellow humans, and I recommend against doing so. Even a psychopath would still be in a common moral reference frame with you, if, fully informed, they would decide to take a pill that would make them non-psychopaths.

How sure are you that most human moral disagreements are attributable to
"I do not eat steak, because I am uncertain of what my own morality outputs with respect to steak-eating.

Accepting your propositions for the sake of argument, I still find that eating steak seems reasonable.
"Rather, it is essential to the concept of morality that it involves shared standards common to all fully reasonable agents."
If you're going to define 'fully reasonable' to mean sharing your moral axioms, so that a superintelligent pencil maximizer with superhuman understanding of human ethics and philosophy is not a 'reasonable agent,' doesn't this just shift the problem a level? Your morality_objectivenorms is only common to all agents with full reasonableness_RichardChappell, and you don't seem to have any compelling reason for the latter (somewhat gerrymandered) account of reasonableness save that it's yours/your culture's/your species.'
Other moral issues where there are a gender differences include: "should prostitution be legalised" and "should there be tighter regulation of pornography".
Again, it seems that part of the effect is due to people's idea of what is right being influenced by their own personal role - i.e. the "different optimization processes" effect.
Gender is the most obvious source of such issues, but I'm sure you can find them in other areas of life. Race politics, for instance.
People in general do not want to be shot. The person doing the shooting, the lethal weapon being fired, the location in which the shooting occurs and the time of day are all pretty much irrelevant. You can ask people if they want to be shot and they'll say no, without even specifying those details. That seems a very different case from Bob, who is considering a moral proposition and outright rejecting it.
Given all of Bacon's idols of the Mind can you ever know definitely if there is an error in your own reasoning, let alone the other persons?

I should qualify this statement: "As such, we shouldn't expect much more moral agreement from humans than from rational (or approximately rational) AIs."
to instead read:
"As such, on ethical questions that had no precedent in our EEA, we shouldn't expect much more moral agreement from humans than from rational (or approximately rational) AIs, apart, of course, from the fact that most humans share a common set of cognitive biases"
one can see that this is true by looking at the vast disagreements between different moral philosophers consequentialists vs. deontological ethicists, or atheists vs. christians vs. muslims, or libertarians vs. liberals vs. communists.
You have been priming people to think in terms of functions. (Pure) Functions do not change. They map an input to an output, and can be substituted by a list, e.g. a function that tests for primality can can be performed by an (infinitely) long list.

I find Roko on-point. The psychological unity of humankind is important, but it can be over-stated.

When we shut up and multiply by sufficiently large numbers, very small differences in the starting point are very meaningful.

Steven, even so, I think the basic question stands. Why should cultural differences and within-sex individual differences wash out of the CEV?
Supposedly genetics allows for people of different ages or sexes to have different mental machinery, whereas individual genetic differences just represent low-complexity differences in tweaking. I'm not sure why that makes Eliezer's point though, if the aforementioned differences in tweaking mean different complex machinery gets activated. Cultural differences I'd expect to wash out just through people learning about different cultures that they could have grown up in.

If you meant to say "most of them are the ancient Greeks", then sure.
On second thought I suppose it could mean "being a jerk according to 'ethics'", where "ethics" is conceived not as something intrinsically moral but as a practical way for agents with different moralities to coordinate on a mutually acceptable solution.

Virge: The argument for psychological unity is that, as a sexually reproducing species, it is almost impossible for one gene to rise in relative frequency if the genes it depends on are not already nearly universal.

I love your turn of phrase, it has a Cold War ring to it.
The question why anyone would ever sincerely want to build an AI which extrapolates anything other than their personal volition is still unclear to me. It hinges on the definition of "sincerely want". If Eliezer can task the AI with looking at humanity and inferring its best wishes, why can't he task it with looking at himself and inferring his best idea of how to infer humanity's wishes? How do we determine, in general, which things a document like CEV must spell out and which things can/should be left to the mysterious magic of "intelligence"?
This has been my thought exactly. Barring all but the most explicit convolution any given person would prefer their own personal volition to be extrapolated. If by happenstance I should be altruistically and perfectly infatuated by, say Sally, then that's the FAI's problem. It will turn out that extrapolating my volition will then entail extrapolating Sally's volition. The same applies to caring about 'humanity', whatever that fuzzy concept means when taken in the context of unbounded future potential.

Recovering, if I write CEV then it ought to work on hunter-gatherers, but the hunter-gatherers could not plausible have understood the concepts involved in CEV (whereas I might be willing to try to explain it to Archimedes, if not any other Syracusans). So "think of a strategy such that it would work for hunter-gatherers" fails here; I can't visualize that counterfactual unless the hunter-gatherers have the concept of math.
The apes fighting around the monolith are outside my moral reference frame and a CEV focused on them would produce different results.
Roko, it doesn't just edit incorrect factual beliefs, there's also the "what if we thought faster, were smarter, were more like the people we wished we were", etc.
Steven: "what if we thought faster, were smarter, were more like the people we wished we were"
- yes, I'm aware of this, but the first two act in essentially the same way - they cause simulees to more quickly come to factually correct beliefs, and the last is just a "consistent under reflection" condition.
These conditions make little difference to my concern: the algorithm will end up mixing my values (which I like) with values I hate (religious dogma, sharia law, Christian fundamentalism, the naturalistic fallacy/bioluddism ... ), where my beliefs recieve a very small weighting, and those that I dislike receive a very large weighting.
If you think an IQ-200 extreme-polymath pope who pondered all current and future arguments for atheism would still remain a Christian, then maybe.

Unfortunately, I know from personal experience that there are people who are more intelligent than I am who have been "hooked" by religious memes. I know of several Cambridge mathematicians who are currently at PhD level, one of them in mathematical logic, who are members of this evangelical Christian organization. One in particular is extremely bright: triple first, British mathematics Olympiad... (read more)
If there are smart Christians out there, then where are their works?
The nearest I thing I ever saw was probably Philip Johnson - and he's not that smart.
Time - Philip Johnson is not just a Christian but a creationist. Do you mean, "if there are smart creationists out there..."? I don't really pay much attention to the religious beliefs of the smartest mathematicians and scientists and I'm not especially keen on looking into it now, but I would be surprised if all top scientists without exception were atheists. This page seems to suggest that many of the best scientists are something other than atheist, many of those Christian.
PhD in mathematical logic != extreme polymath. I guess Dyson and Tipler come closest to refuting my position, but I wouldn't expect their beliefs to remain constant under a few thousand years of pondering the overcoming bias archives, say.
You can bring a brain to data, but you can't make it think.
Things like an IQ of 200 indicate that a person has certain cognitive strengths. They DO NOT indicate that those strengths will be utilized. Someone who is not concerned about being dishonest with themselves can self-convince of whatever they please.
At this point, there are no rational grounds for a person to accept the truth claims of, say, the various Christian doctrinal groups. A person who accepts them regardless has already decided to suspend rationality - unless a desire for honesty greate... (read more)
What I mean is, if there are smart Christians out there, why can't they put together a coherent argument favouring Christianity?
I mean, is this really the best they can do?
"a coherent argument favouring Christianity"
Catholic people believe that they have such a thing, resting on strong philosophical definitions of ontology and truth. Traditionally I think that if one was truly interested in hearing a coherent argument for Christian belief, the Jesuit order specialized in teaching and expounding the philosophy. Short a long session with a Jesuit, you might consult the Catholic Encyclopedia for Christian arguments.
While perhaps you will ultimately agree that their system is coherent, that is, "marked ... (read more)
Caledonian and Tim Tyler: there are lots of coherent defenses of Christianity. It's just that many of them rest on statements like, "if Occam's Razor comes into conflict with Revealed Truth, we must privilege the latter over the former." This isn't incoherent; it's just wrong. At least from our perspective. Which is the point I've been trying to make. They'd say the same thing about us.
Roko: I sent you an email.
I think the idea of associating the meaning of a word with a detailed theory of fine-grained set of criteria, allowing you to apply the term in all cases, has disadvantages.
Newtonian theory has a different set of fine grained criteria about gravity than relativistic theory. If we ta... (read more)
