How is "effective" defined?

Not really, no - unless you have an unusual definition of realism. In AI, the idea that you can create an intelligent machine by just chucking more and more data into a bucket is pretty much dead - 'intelligent' behaviour is all about paring down the data into the simplest, most robust model which does the job - that often has very little if anything to do with realism.
If you want a very simple published example, you could do worse than this:

Don't notions of good correlate more closely with geography and social context? What evidence do you have that notions of good correlate with "needs and desires"?
Marios wrote:Peter Grant wrote:- Individuals with more realistic self models will behave more effectively than those with less realistic ones.
Still not sure what you mean by "effective" or "realistic", but it's hard to see what would necessarily benefit from "realism" except "realism".
Marios wrote:Peter Grant wrote:- These individuals and the societies they are part of will tend to behave more morally and more generally be considered good.
By whom will they be considered good? If "- We each have our own personal concept of good based on our own needs and desires" then how can you say "moral morally"/"considered good" without specifying who is the person doing the judging?

Okay, you mean biological fitness? Remember that the "effective behaviour" is a rapidly moving target and will tend to involve the behaviours of other conspecifics.

Actually, the philosophy forum is where I expect to find the absolutists - evolution and natural selection is where I expect to find the methodological naturalists.

Sorry, if I'm reading you right, that's really the sort of thing that's only allowed in philosophy. In evolutionary biology, that would get you hauled up as a social darwinist. You can't just project your beliefs about what "the good" entails onto your model and call it science.
Given that your whole argument depends on whether what you're claiming evolution selects for is actually selected for, I think this is where you need to make your case very clearly without skipping any steps.

I'm afraid arguments from intuition fall down on the fact that different people "readily deduce" different things using their common sense intuition.
If you're just saying "Some components of social behaviour are correlate more with social context than genetic context" then I think that's fairly uncontroversial.

I'm not sure if we're in total agreement or total disagreement. When you say "problem we can solve" do you mean the four scientific questions you'd ask about any evolving system -

Hmm - I think you might be confusing two senses of the word 'subjective'. Morality is subjective in the sense that there's no external reference to compare it to. If I say I think female circumcision is right and proper, you can say you think it's wrong - what you can't do is say I think it's wrong, but I'm just confused. If I say a metre is 83 centimetres long, then I am in just in error (insofar as we accept that the metric system/dictionary should define how words should be used).
I don't morality is usually viewed subjective in the sense of a hidden experience which cannot be observed - depending how you use the word you could be talking about observed expressed beliefs or observed actions.
Marios wrote:Peter Grant wrote:However subjective "the good" may be, the ability to judge other's actions as either good or bad must be genetically based.

Marios wrote:Peter Grant wrote:If morals really were as subjective as is made out then it would be impossible for any multi-cultural society to function.
I think you have to clarify how the word "multicultural" is used. What it _does not_ mean is two distinct cultures living entwined among another - there is no culture in the world that I know of where one culture isn't dominant. There is nowhere in the world where half the people go to Western Christian Churches and the other half worship Huitzlipoctli through biennial human sacrifice - either Huitzipoctli is in charge and a few small Churches are tolerated/run underground or Christianity is in charge and Huitzlipoctli human sacrifices have to go on underground. In Britain, multicultural means that we tolerate foreign cultures so long as they don't do anything we really don't like. Funny hats, weird architecture, yes - wearing bits of cloth over your face, body alteration of the kind we don't like, espousing alien political systems, no. Even then, multiculturalism as a term is becoming increasingly unpopular - no one wants to say "assimilation" - but most everyone kind of wants it to happen, just as long as we don't have to _see_ it happening. Nor is it just the UK - Holland, most liberal and progressive of countries, has recently undergone the same shift. People liked living in a 'multicultural' society, just so long as the culture showed no signs of changing.
Marios wrote:Peter Grant wrote:In seems that there would be a strong selective pressure in favour of uniformity in all subjective elements that influence moral decisions so that the individuals would make good moral judgements whatever culture they grew up in, and this seems to be the case.
Again, you probably don't want to use the word "good" when you're talking about morality, particularly when the most obvious heuristic for 'getting along' in society is 'keep your head down'.

I can't see what you're saying here - do you have any anthropology references to back this up?
Marios wrote:Peter Grant wrote:How could the ability to predict behaviour be a disadvantage?
For one, because the interests of the individual do not align with the interests of the genes. For instance, in humans, unlike almost any other animal, the fertility of the female is deliberately obscured from both the female and everyone else. This isn't just an example of a failure to evolve a capacity to make certain vital predictions (and there are few things more vital to biological fitness than when you are/are not fertile), but a clear example where ignorance has been selected for.
Marios wrote: More generally, as the little toy sim by Doran showed, in any situation where you have (i) less than total knowledge

No, I meant conformity in the sense that you were saying "It is good because other people judge it to be good". Aztec human sacrifice is good if most Aztecs agree that it's good? A definition of "good" that I'm happy with, but which doesn't seem to suit the rest of your model.

Yes, I don't have a problem with behaviour being 'indirectly' governed by genes and environment - in the same way that all phenotypic traits depend on the interactions of genes with their environment - I'm just not clear if you're saying anything more than "there are genes which affect how behaviours are socially transmitted and received" - which I don't think anyone would disagree with (short of removing themselves from any scientific discussion).

No, I'm sorry, the validity of any scientific discussion touching on culture really does hang on whether you're willing to adopt methodological cultural relativism. It doesn't reflect on what you believe in your personal life anymore than it matters whether chemists go to Mass once they leave the lab - so long as they are methodological naturalists in the lab.
Wikipedia wrote:Virtually all anthropologists today subscribe to the methodological and heuristic principles of Boas and his students in their research. But, according to Marcus and Fischer, when the principle of cultural relativism was popularized after World War II, it came to be understood "more as a doctrine, or position, than as a method." As a consequence, people misinterpreted cultural relativism to mean that all cultures are both separate and equal, and that all value systems, however different, are equally valid. Thus, people came to use the phrase "cultural relativism" erroneously to signify "moral relativism."
Wikipedia wrote:Evolutionary biologists believe that morality is a natural phenomenon that evolved by natural selection acting at the individual level, and through group selection. Consequently they view morality as being relative, constituting any set of social behaviors that promoted the survival and successful reproduction of humans
Marios wrote: I'm not really clear on what you're saying here 'unknown individual factor' within 'the context of any social system'? Sounds like you're assuming a supervening moral system - like CS Lewis did when he said:The answer [to the claim that cultures radically differ on their moral codes] is that this is a lie—a good, solid, resounding lie.
He then went on to argue that witchhunters weren't evil because they were acting according to universal morality in the context of the mental models they had (i.e. witches are effectively mass-murdering terrorists - worse, there is no safe place you can lock them up).
Granted, that's a step up from someone says "Witch hunters are evil because, according to contemporary moral principle and contemporary models of the world, they did evil things", but it still assumes that there's such a thing as Universal Morality - which is a faith position (CS Lewis wasn't inconsistent here - yes, he dismissed anthropology as a pack of lies - but he was clear that all his arguments were founded a basic commitment to faith - he wasn't trying to present a scientific model).
Maybe that's not what you mean, but any discussion on applying scientific principles to human cultures requires that you first state whether you're adopting methodological cultural relativism (I'm not sure there's another kind!) to present a scientific model or whether you're presenting a model partisan to a specific moral conviction. The worst thing you can do is not be clear about which it is.

What does "least subjective harm on an individual basis" mean?
Marios wrote:Peter Grant wrote:A hidden experience which cannot be observed is exactly how I would define a subjective experience.
Yes, that's what I mean - there are two senses of the word "subjective"
(1) "Subjective experience" is an experience no third party one can observe (qualia)
(2) "Subjective opinion" is an opinion that we can observe easily ("Do you think abortion is wrong?" "Yes"), but that we can't objectively determine to be true or false (it's true that they said it, but is it true that it's wrong?).
I think you're morality is subject in sense (2), but you seem to be describing it in terms of sense (1).

In that paragraph, yes, but not in the sentence I quoted:Peter Grant wrote:If morals really were as subjective as is made out then it would be impossible for any multi-cultural society to function.
The implication here is that you seem to be following CS Lewis in assuming that cultural variation is vastly overemphasised.
Marios wrote:Peter Grant wrote:In this example there is no way to know if the female is fertile. It is not a failure to predict behaviour that has been selected but the impossibility there of.
No it isn't - chimps and bonobos both have visible signs of female fertility - subsequently selection has acted to make women and observers unaware of the fertility of that woman. If more and more accurate information was always advantageous - as you seem to be assuming - then how come human females have deliberately been selected for ignorance as to the state of their fertility, while female chimps and bonobos have not?
Marios wrote:Peter Grant wrote:In this example the behaviour was programmed directly. The bots did not construct models of their own environment and base their decisions on them.

Yes, that's what I mean by 'methodological cultural relativism' (like methodological naturalism). I think that to work in anthropology (science) you have to be embrace these as methodological requirements. Most scientists aren't actually naturalists outside of the lab - they are perfectly comfortable going to Church or using dualist constructs like "I" and "you" - equally, most anthropologists do actually seem to have their own personal preferences for when they are in their own societies.

Yes, and some sets of genes seem to have been more likely to replicate themselves in the past - the result is not one kind of SuperAnimal but a vast diversity of organisms in different niches. Again, remember that group selection is no longer valid in any sense that distinguishes it from individual selection (I think the terms are _really_ unhelpful here, but some people do prefer to view the maths that way around) - social behaviours promote the survival and successful reproduction of those social behaviours insofar as they are socially transmitted. If you want to consider the effect of gene-culture coevolution you end up with some quite gnarly maths which doesn't really fold down into neat little answers.
Marios wrote:Peter Grant wrote:I agree that cultures radically differ on their moral codes, but I think they use roughly the same methods of devising them based on the available information.

Right - so not only are you edging towards ignoring variation between cultures, but you're also ignoring variation within a culture - trying to get a simple answer by dumping everyone into a blender and hoping something meaningful will come out? I'm sorry, but this approach seems considerably cruder than the sorts of agent-based models used to study less socially complex primates.

No, I think you're missing my point - or assuming some induction model for _all beliefs_. If someone says "I think abortion/female circumcision is wrong" that is what I would view as a subjective opinion. I'm not sure what you mean by 'objective facts' and 'subjective experience' there

Incorrectly assuming? I think that rather depends on what you mean by "purely a cultural phenonemenon". Certainly C.S. Lewis felt that it wasn't "purely cultural" - he felt that morality came from God - when someone makes a claim that they think there's some 'privileged morality' that underlies the 'superficial' variation I think it's perfectly reasonable to be skeptical, given that almost every culture seems to view their specific cultural morality as in some sense universal.

It's an interesting line of conjecture - although perhaps a little implicitly Chauvinist. Women evolve the inability to be aware of their own fertility because they wouldn't be able to keep it from men who would then exploit them? Surely _first_ we should consider the simpler conjecture that women evolve the inability to be aware of their own fertility _because of how it influences their own behaviour_ (i.e. sex without pregnancy)?
Either way, you seem to have accepted that actually it isn't necessarily always advantageous to have more/more accurate information (even if we assumed this was costless). Once that's conceded we can no longer assume that there's just one optima and the beliefs and desires of individual agents needs to be considered separate from biological fitness.

Scientific models should never be any more complicated than they need to be - the point of the model was to communicate the point that it isn't necessarily the case that "more accurate information implies higher biological fitness" - if anything, he's maybe put more than he needs to in one paper (the second simulation).
Marios wrote:Peter Grant wrote:It does predict that holding false beliefs is only effective when the majority of agents in a society hold that belief, which I agree with. It also says that those false beliefs are only effective when they correlate with reality in some way:
Yes, but bear in mind that for social organisms one of the principle elements of the "agents' environment" are the beliefs of the other agents.

This is the sort of question you need to look to answering - but it's important to grasp that there's a limit to what you can do just by referring to your own intuition (otherwise scientists wouldn't waste time with maths and experiments - we'd still be Natural Philosophers chewing the end of a pencil and trying to decide which essay seems 'more plausible' than the other).
Marios wrote:Peter Grant wrote:I am making no comments about Aztec culture. I'm simply claiming that our model of the solar system is better and pointing out that one is less likely to draw conclusions from it linking human sacrifice to sunrise events.
Sorry, I don't agree - I think you're falling down here:Peter Grant wrote:The main difference between us and the Aztecs is that they thought the the sun would not come up without human sacrifice.
By ignoring the fact that the Aztecs had a totally different culture you're implicitly assuming that they share all our values about what defines a model of the solar system as 'better'. I think the main difference between 21st century Westerners and the Aztecs is that we live in totally different cultures. I don't think it's informative to reduce an entire culture to "they had this weird idea about the sun not coming up if they didn't do blah" and then infer that all differences herald from that - you're putting the rationale for a behaviour _before_ the behaviour, which on a historical timescale is usually a big mistake (as far as I recall, we're talking about 500 years of human sacrifice prior to the rise of the Aztecs and their subsequent development of theology, so I think you're confusing cause with effect).
Marios wrote:Peter Grant wrote:Based on their model of the universe their behaviour was completely justified. Our model is better.
This is exactly the same as C.S.Lewis's argument about witchfinders not being bad people. I'm certainly not disagreeing with the idea that you've got to look at belief systems in context, but the suggestion that you can assume that there's two contexts - one of which is changing and fallible human knowledge - the other is ultimate, underlying eternal truth - is implicitly religious. Obviously, that's not a problem for C.S. Lewis because he's arguing that religion is necessary, but it strikes me as a problem for you if you're trying to present this as a scientific naturalist approach.
Marios wrote: If you don't do that, all you can conclude is that our model is better from our point of view (which is fairly trite). If you want to argue that Aztecs would have automatically viewed our approach as better, then I'm going to ask for evidence (which is hard since when the two cultures came into contact, Aztec culture was rapidly destabilised with disease and conquest).

The cycle of fifty-two years was central to Mesoamerican cultures. The Nahua's religious beliefs were based on a great fear that the universe would collapse after each cycle if the gods were not strong enough. Every fifty-two years a special New Fire ceremony was performed.[18] All fires were extinguished and at midnight a human sacrifice was made. The Aztecs waited for the dawn. If the Sun appeared it meant that the sacrifices for this cycle had been enough. A fire was ignited on the body of a victim, and this new fire was taken to every house, city and town. Rejoicing was general: a new cycle of fifty-two years was beginning, and the end of the world had been postponed, at least for another 52-year century. (A similar ceremony is still practiced by small indigenous groups, but without human sacrifice.) The ceremony was older than the Aztecs. While originally it was believed it was a matter of luck to survive, the Aztecs thought that constant sacrifice through the fifty-two year cycle could postpone the end.
Peter Grant wrote:The above has been demonstrated to be false as there have been numerous fifty-two year cycles since the practice has ceased. Presumably the god's strength is not dependant on human sacrifice after all.

Will come back to that too in a bit.

And we've certainly demonstrated that variation within populations (which can include cultures) is greater than variation between populations where humans are concerned.

I think you're missing a clause that would be necessary for this sentence to mean what you wanted it to mean.

hotshoe wrote:I'm sorry, I guess it was me who was missing something today.
I guess you mean that the variation within populations would be sufficient to give selection something to work on, variation in how much an individual's ethical system tends to better work with biological imperatives ?

As I said, that would be true if:
(i) that's an accurate and complete reconstruction of a prevalent Aztec worldview and
(ii) mental models dictate cultural practices strictly (rather than cultural practices dictating mental models or some more realistic coevolution model)
Marios wrote: For instance, a lot of people believed (and believe) that "Science will create a better world" before WWI/WWII. Many of their predictions turned out to be entirely false (have a read over late 19th century/very early 20th century utopian literature) - but not many people said "Hmm, well that's clearly incorrect then, I had best resign my comfortable little professorship and give the Mormons a go". What they did was that they discarded inconvenient predictions and redefined terms - even the old favourite ("Hmm, well it would have, but Bad People stopped it").
Marios wrote: That's not an unrepresentative sample, either - I would say that's generally the rule for any cultural system (think of any of the well documented cultural models of the last century) - the only system where that doesn't occur is science (and even then it's an uphill struggle to persaud people to abadon theories just because the predictions don't seem to have panned out).
Marios wrote: I think the mistake is in assuming that the observable predictions of a system of thought are what's actually important about it - outside of the natural sciences, I can't think of a system where that's true. Observable predictions are more like are like origin myths in religion - just because they logically or historically seem to be predate the religion doesn't mean they actually do (people who have no experience of religion beyond Christianity often seem to get confused by the idea that other religions - including early Christianity - often have multiple origin myths).
