Fair point—I should have phrased that differently. I think I intended that both in the weak sense “Our prior on moral statements should never be 0 or 1” and also in the slightly stronger sense “Ethics is difficult, so our priors should have high variance”

I want to point out that I, perhaps incorrectly, assumed this thought experiment could be interesting even to the anti-PUA crowd, because it would help them distill their thinking about whether they object to PUA on epistemic grounds (“they have incorrect beliefs about female psychology”) or if they object on moral grounds (“they draw incorrect / evil conclusions about the ethical implications of the theory”)

From the reactions, it is tempting to conclude that most people object to PUA partially on epistemic grounds. However, it is hard for me to understand why a disagreement about facts would lead to such heated debate in a community based around the Litany of Tarski.

Your translation of the analogy takes the postition that the status dichotomy is a thing. The rest follows from that assumption.

No, it takes the position that there exist people who believe status dichotomy is a thing, and then explores some of the consequences if this belief were to be true.

Moreover, status dichotomy is very obviously a lossy compression. For some purposes, this construct will lose so much information as to be useless. For other purposes, the information that is lost by dichotomizing status is not essential, and so it may still be a useful model.

In order to convince me that dichotomous status is not a useful model when what we are interested in is exploring the ethical issues in this post, you would have to show me a situation where considering a continuous or multidimensional status construct is necessary in order to make an essential point with implications for the correct ethical choice. If you are able to do this, you will have contributed a lot to the conversation, and I will have learned something important.

Being a pleasant person to be around is beyond a man’s responsibility?

No, what I meant was that a Martian cannot be held morally responsible for whether he is Green or Blue.

I am a moral realist, I believe there exists an objective moral standard which is part of the territory. This is the moral standard we are talking about.

Obviously, we are unable to know whether our ethical maps correspond to the ethical territory. We should therefore update our priors about the ethical territory in response to good arguments and thought experiments. Throughout this discussion, I have made several updates to my beliefs.

If we don’t believe there is such a thing as an objective ethical standard, if the territory doesn’t exist, then I fail to see the point in even discussing ethics.

Thank you, this is exactly the kind of discussion I was hoping for. I don’t really have anything to add, I agree with essentially everything here. Can we can please keep the discussion at this level?

I am certainly learning from any useful comments that are made, regardless of which position they take. This is not one of those comments. It is also the only comment in the thread which I have downvoted—I am trying to have a discussion about ethics in a hypothetical world, not a flame war.

Those are not my views:

First of all, I took no position on the truth value of the premises.

Secondly, I fully recognize that my analogy is a simplified map of a map. It does not accurately represent the full territory.

The question is whether the aspects of the territory that I have glossed over are important for the resolution of the ethical question. If there are any such aspects, please feel free to point them out. I do recognize that some of the aspects that have been pointed out, such as consent, are important. I have upvoted those comments and attempted to explain why I think you can make the argument that the analogy still has some validity.

Let me just point out that the post was an attempt to discuss ethics in a hypothetical world where certain PUA claims about human psychology are true. I think this is an important question, and I did not want it to degenerate into a discussion about whether the claims themselves are true.

I tried my best to make the analogy as neutral as possible, by making women the “humans”, describing the PUA strategies as having a real harmful effect on women, and generally making their dislike of PUA strategies seem entirely reasonable.

I don’t see how the post is tendentious. I don’t think the analogy has any obvious ethical solution, and I am genuinely asking people for insight into what the relevant ethics are in this hypothetical world. I don’t see how I am leading people to give me validation on my views, because I am not even sure what my views are.

OK, I really would prefer that this discussion stays on the abstract level, but in order to avoid confusion, I will provide a translation of the intended metaphors:

Green Martian = Low Status Male

Blue Martian = High Status Male

Earthling = Female

Tickling = Flirting (Including obnoxious strategies such as “negs” and “kino escalation”)

The moderately painful sting of the tentacles of the Green Martian = Creepiness, Social Awkwardness, etc

Experimentation on Earthlings (defined in comments) = Sex

OK. Good point. I am going to specify that in this thought experiment, tickling is only effective if there is no explicit consent.

Edit: See definition of tickling here: http://lesswrong.com/lw/klx/ethics_in_a_feedback_loop_a_parable/b5ft?context=1#b5ft

Also, note that this is a thought experiment. The point of this comment is not to make a claim about the truth value of the statement “flirting is only effective if there is no explicit consent”, but to explore the ethical consequences of a world in which this is true.

I definitely see the humans as agents, whose preferences are morally relevant. In fact, the reason this is even ethically ambiguous in the first place, is that humans have a preference not to be tickled by green martians.

The reason humans come across as passive, is that I am specifically asking about the ethics of an action that is generally conducted by the active Martian to the passive human. It is at least theoretically possible that this question can be resolved without considering any ethical dilemmas that the humans face. This does not mean that the humans are not considered as important moral agents, only that their agency is not something that has any impact on the ethics of a choice made my Martians.

If you can think of a reason why having a full map of the ethical agency of the human is necessary to resolve the ethics of the choice faced by the Martian, I would be very interested in hearing it and will update accordingly.

In this society, it is generally accepted that tickling is not something that requires consent.

Even more than the Martians want to tickle humans, they want to carry them away to their mothership to experiment on them. Everyone agrees that experimentation on humans requires their consent. Part of the socially accepted foreplay that sometimes leads to humans giving their consent to be experimented on, consists of the martian tickling the human behind the ear.

A source is “Allison, Richard. “Organic chicken production criticised for leaving a larger carbon footprint.” Poultry World. 1 Mar. 2007”. This article is behind a paywall. I am pasting a table from the article:

AVERAGE ENVIRONMENTAL IMPACT FROM POULTRY PRODUCTION (% DIFFERENCE TO CONVENTIONAL) Organic Free range

Energy use +33% +25%

Global warming potential (CO2) +46% +20%

Eutrophication potential +75% +28%

Acidification potential +52% +33%

Pesticide use (dose/ha) −92% +12%

Note: This article is in a trade publication and could be biased. It is based on an original report which I could not locate, and which apparently has sparse data. Obviously, more research is needed.

My prior beliefs are not the result of scientific studies, but follow from the following observations:

(1) To reduce global warming, we need to maximize the number of calories produced per unit of CO2 emission

(2) The most effective way we can alter that ratio, is by reducing the amount of biochemical energy that is used to power the biochemical processes of farm animals over the course of their lives. This is primarily a function of duration of their lives.

(3) Factory farming achieves shorter duration, by having the animals grow more quickly

(4) Another way we can reduce the net amount of CO2 produced per unit food, is by reducing the amount of land used, thus allowing less deforestation.

(5) Factory farming achieves this by using less land

(6) I cannot see any other mechanisms that differ between factory farming and organic farming which would have a major net effect on the carbon cycle.

I only think factory-farmed meat is the problem. I use “eat less meat” as a shorthand, since nearly all meat is factory-farmed meat.

Factory-farmed meat converts photosynthetic energy (grass) to food much more efficiently than free-range farming. Factory farming requires less inputs in terms of arable land and water, and emits less CO2. If everyone in the world ate non-factory farmed meat, we would have to cut down the Amazon many times over, thereby drastically reducing earth’s capacity to convert CO2 back to carbohydrates.

When you decide whether your meat should be factory farmed or not, , there are consequences on two scales that are negatively correlated: Animal welfare and global warming. Which of these scales you give most weight to, will depend on your prior for anthropogenic global warming, on your beliefs about the consequences of global warming, and on the priority you give animals in your aggregation scheme over individuals with moral standing.

What is more ridiculous about MIMO than CICO? Conservation of matter, can’t argue with that.

OK, I see the point. But multicellular life evolved as thermodynamic engines, not as fusion plants. Over billions of years, cells were surviving based on how efficiently they could extract thermodynamic energy from macronutrients, to power intracellular processes. This is what we are optimized for. If we had been able to use fusion power in our evolutionary past, MIMO would be a more appropriate level at which to draw your map.

There is obviously thermodynamic energy in food which is not absorbed in the gastrointestinal tract. Fiber is an example of this. Energy which is not absorbed is not listed on the nutrition label of food. When I say ‘calories’, I mean the biochemically available energy in absorbed macronutrients such as fat, carbohydrates, protein and alcohol.

Nobody doubts that thermogenesis uses energy. This is a special case of my mechanism 3. It is part of the ‘energy used’. Again, if you want to convince me that you can eat 3000 calories of fat without gaining weight, you would have to make an argument that the proportion of fat in my diet has a causal effect on thermogenesis, ie, that my body will start running additional thermogenesis because I ate fat instead of carbohydrates.

Your claim that CICO is as helpful as MIMO is clearly ridiculous, and if you truly believe this, then supermodels eating tissue paper are more rational than you, as their beliefs will lead to more accurate predictions.

The point I am trying to make is that our body is an efficient engine due to evolutionary pressure, that energy doesn’t just disappear (if it did, we would observe large amounts of unmetabolized macronutrients in urine), and that even if CICO is not the whole picture, it explains a very large part of the variation in body weight observed in human populations

OK. I’ll accept your rephrasing. Let us assume that “calories out” is always difficult to estimate and depends on a lot of factors such as muscle mass and total calorie intake.

I took the original comment to mean that we can eat very large amounts of fat and protein, because our bodies would somehow react, in response to the proportion of different nutrients in our diet, and change how efficiently we use energy. I find it difficult to believe that this would explain much of change in body weight. I find it much easier to believe that it would change our appetites and thus reduce calorie intake.

I am certainly willing to update my priors if someone convinces me of a plausible mechanism by which proportion of each nutrient alters efficiency of energy use..

This article says that there is some non-absorption of fat in healthy people, and much greater non-absorption in people with cystic fibrosis.

If you want to convince me that I should consider this when I choose the fat/carbohydrate/protein content of my diet, you would have to make an argument that the percentage of fat that is not absorbed is a function of my diet, ie, causally related to what I choose to eat.

I’m not saying this is not theoretically possible, but my intuition tells me that the variation in absorbtion that is caused by diet, is unlikely to have a major impact in the final analysis

Thank you, that was helpful.

Note that I don’t disagree with anything in that Mayo Clinic article. The point about “pounds of fat, muscle and water” is obviously true and does not contradict anything I said. The points about “metabolic rate” and “response to reduced calories” just seem to say that sometimes it is difficult to estimate the “calories out” part of the equation, and that it is endogenous to the system. This is also obviously true. I still find it difficult to believe that we can affect the metabolic rate to an extent that matters in the final analysis, based on the fat/protein/carbohydrate content of our diet..
