    Do you know how to read a comment on its merits?

    False distinction. How I read your comment depends on your education, because it determines if you are using technical terms in a manner consistent with a layperson or not. Much like how if someone is describing the power button on their CPU, what you would imagine from a hardware engineer (maybe an on-board jumper/microswitch) or a secretary (the power button of a computer) would be different.

    What you're describing as the "ultimatum game" is not what an economist would describe as the ultimatum game. Although played with two people, the goal is not to win... the economy is not closed. That is, they literally bring you each into a room (same or seperate), tell you both that one of you will be given $[Amount of money in the study] and allowed to divide it up. The other person then determines if both people get what the first person suggested or both people get nothing. They then go do whatever they feel like for the rest of their lives.

    As you can probably guess, the amount of money is rarely super-significant... it's a meal or a movie ticket or something (although there were a couple of studies that tried pretty significant sums and then went to poorer countries so they were even more significant.)

    Therefore, in this game, I fail to see where competition factors in as a motivation to reject a proposal.

    I think the study is poor because it doesn't distinguish aggression from accurate analysis of the situation/probabilities of various outcomes. Experience makes people better... about 4% better at determining what other people will do over a career. Stop the fucking presses! But I was talking about the differences youth make in the ultimatum game.

    You listed two options, and I'm not sure what you're asking or implying. I mean, I'm really trying to understand but am unable to. I feel this is because you're referring to a theoretical model that doesn't exist. The theoretical model to the Ultimatum game goes something like "People will pay money for revenge/to not feel cheated". That's it. Simply that people will spend money for no material benefit and to prevent someone they dislike from having something.

Not that a free market is the best thing in the world... regulation to deal with racism for instance is desirable.

    not arbitrarily deciding what can and cannot be a criterion, I made a very clear rule: making your product better = good, making others' product worse = bad

    Well, if I can make my product better by making your product worse, where does that fall. For instance, suppose you have the choice of hot dog A and hot dog B, no difference in quality or price. So 50% of the time you buy A, and 50% you buy B (depending on which is closer to you when you want a hot dog). Now suppose I tell you brand A saves puppies with 1/2 its profits... nothing about brand B. You now get the benefit of hot dogs and saving puppies, so you have a preference for brand A. Clearly, you now have more value for your dollar.

    Now, suppose I add that psychic benefit some other way, by saying that brand B devotes 1/2 their profits to killing puppies. You get a psychic benefit out of hurting them. You still are happier in that case, even though you're getting the same physical product. Brand A wins. Customer wins. Brand B loses.

    once you realize that sending soldiers against Brand B's factory is identical to sending lawyers against them or using dirty advertising tactics against them.

    But they aren't. In the case of advertising, you are changing how much Brand B and Brand A are worth. You are literally raising the total utility of hot dog purchases. This result means that society is now richer.

    . Scientifically, the question about skin color actually has been settled. A not-insignificant amount of work went into it, too, to show that race is a social and not a scientific distinction.

    How does the science change anything? Just in case you're not sure what I'm referencing, the US Constitution originally valued a black person as 60% the worth of a white one. And I'm not sure how science can really inform us any differently. Even if the cause was culture or upbringing or "being not allowed to read under penalty of death", that value was still assessed.

    To behave as though an issue has been settled when the facts are not yet known to that degree is a rhetorical tactic, not a logical one.

    But they believe the issue is settled. And since science cannot inform us differently (see below), they're perfectly right to believe that.

    Defining life and when it begins, if we consider it a question worth answering, is exclusively a question of science (unless you know of a way to investigate such questions in some other way?).

    I fail to see what science can add. It becomes a question of potential. Science really has made bad calls about what is and isn't a person, some current leading medical ethicists want to revive euthinasia or take other steps to "strengthen the genepool". What is the scientific test for sentience? Potential to become sentient?

    Science is good for telling us how the world works, and making predictions. It's even pretty good at telling us what happened. But it's utterly silent on morality, theology, philosophy and other worthy endevors. If you think science can help here, that's great, but the burden of proof is on you.

    You're arguments about specialists where you quote several examples (nuclear engineering, military strategy, etc.) are all offbase because those are specialists making decisions that concern their specialty. I believe that people who have studied a lot can help a great deal in decision making. But I also believe that they tend to view everything through a single lens, and need to be checked at the big picture level. We trust the nuclear engineer to design the plant (or supervise the design) and understand the cost/benefits of using nuclear power, but not to decide if we build turbines or a plant. We trust the general to order tanks into harm's way in the most effective manner, but we explicitly give control over when that happens to someone outside the military.

    So now all we need to figure out to know whether abortion is ok is: is the fetus sentient yet? ... a reasonable chance of becoming imbued with "sentience"? (What exactly do you mean by the term "sentient"?)

Clearly, given the choice, you would rather make the Third World more like the First World than vice versa. So I would like to see some other line of reasoning for why life is not precious.

    Could it? You're making another assumption that is probably unwarranted. At least, I'd want to see some numbers on the availability of suitable adoptive parents vs. the number of abandoned children.

    For the first year at least... there are approximately a million people who have taken steps towards adoption, but have not yet been able to adopt, and another 8.5 million who are in the preliminary investigation stages. There are around a million abortions a year. Maybe we would have to lower the adoption screening process, but that might be a good thing. After all, we don't have a biological screening process. It'd also help the merging of that melting pot, racially.

I'm offering a third way for you to perform the cost-benefit analysis you were advocating... that where minimum utility instead of mean utility is used.

    The people who will ultimately benefit from stem-cell-derived medical treatments need to figure into this equation. They really do, otherwise the debate is one-sided and serves little purpose.

    I tend to agree they need to factor in. But since there is no real demand for aborted fetuses or zygotes to perform stem cell research, I think factoring them in turns it from a shouting match over sensibilities to being completely one sided. But then again, while I oppose abortion, I don't think that every fertilized egg is a life. To those people, it's murder... maybe profitable murder, but murder none-the-less.

    The problem is, while "kill hobos and use their organs to save the lives of these doomed scientists who can then create artificial organs which will save umpteen million people" is a good deal, human beings are wired to not want it. There are sealed records from Nazi experiments that may have as yet unrediscovered knowledge in it, and there is a medical consensus that even looking at them would be too close to condoning what was done (there is the added benefit of trying to dissuade future scientists who may have been tempted to join a similarly horrific program in the future.)

Humans are more than the sum of their parts, and when that additional piece gets added is up for debate.

    This seems to me to be life worth protecting.

Letting our technological capability guide us here is clearly wrong, too...technology is a tool and a tools don't dictate their use, we do, based on understanding on when and where to apply them.)

I had my 5th grade cousin ask for help on his math homework, and there were literally a half dozen contradictory answers that would be valid based on the assumptions taken in his word problem. (Does "ways it can be arranged" refer to combinations or permutations, can each option be used more than once, can the null option be used (only valid if each option can be used more than once, as otherwise it was required) or can the null option be used more than once (only valid if the other options cannot) ). Kids are bad at math cause we spoonfeed them crap with 800 assumptions, never explaining what they are. And we wonder why they cannot generalize like we can.

    In English - four plus three plus two equals something plus two.

    Why did you have to parse it like that. I parsed it as "four plus three plus two something two". Sure, I recognized the equal sign, and the plus sign, but I also recognized the parentheses. The other way of parsing it for me was "four plus three plus two equals quantity zero end-quantity plus two"... a false statement. I'm used to seeing operators written out as the conjunction of other, sometimes unrelated, operators. I'm not familiar with "()" written out to mean "unknown quantity". In that case I'm used to "x".

    Why are people throwing out the rules when they come upon an unknown?

    I'm not. There are many unknowns there... mainly what the parentheses mean. I applied my best guess. Or, as someone else once said, communicating badly and then acting smug when you are misunderstood is not cleverness.

    If they understood clearly, concretely, what "equals" meant, there wouldn't be the sort of confusion that's been going on

    That symbol was not understandable, unambiguously, as equals. That's the major source of confusion. The equals sign can be used to represent causation "=>", a test returning the truth value of an equality "==", a declarative statement about equality "=", a test of identity "===", and others. What does it represent in "=()+"? How do you know?

    I think another poster had a good theory, that nowadays "=" is seen as "solve it" due to its use on calculators.

    That's an interesting hypothesis, and I would love to see a test of that. Unfortunately, this study was flawed do to its non-conventional usage of "()" as "unknown quantity".
