    "Are you telling me it's possible for me to determine the absolute most beneficial action I should take at any given time?"

    No. I'm just saying you are better at knowing what's best for you than anyone else, and that free market economics leverage that knowledge. Are you saying someone else is better at determining what's best for you than you yourself are?

    The cases you are describing are known as market externalities. Market externalities were mentioned in the wikipedia article I linked to, which I considered sufficient reference to them, but again, I assumed too much.

    I'm not an anarchist. Market externalities are, in my opinion, legitimate fields for governments to get involved. For example, taxing the knife manufacturer based on the estimated cost of solving health problems from their release of lead into the environment so that the price of your knife legitimately reflects its true costs would be a way of eliminating the market externality without forcing you to consider the knife on any other basis than its quality and cost. Once you get the important market externalities nailed, that's the right time for governments to stop getting involved. That's a difficult point to judge and a legitimate field of debate, but no implementation of communism would even try.

    Once you have that point nailed, you've got individual interactions based on individual judgements of utility. The emergent complexity from this system should literally be undeniable. You see it every day. If we can't agree on that, we probably shouldn't even bother to discuss it. That it results in net positive benefits for the group should also be fairly clear. Do you agree on this point?

    Human groups have always been swarms -- they are not a "new" thing. The new thing is optimizing the rules for individual interactions for a desirable emergent property and using new models to do so. The ideas about Pareto optimality as an emergent property of idealized free market economics are also proven using mathematical models. They just aren't new anymore. That doesn't mean they don't fit in with the other research in this field. If they didn't fit, the authors of the National Geographic magazine never would have mentioned betting systems as an effective method for combining the information which individuals possess to predict race outcomes. The effectivity of those systems can be proven using essentially the same method.

    "...my point is that there's no such thing as absolute enlightened interest - selfish or altruistic, and theories that are predicated on it are increasingly demonstrating to be as quaint as the old "clockwork" model of the world"

    And if you can't see that I'm not talking about "clockworks", then you may not be making an honest attempt to understand what I'm writing.

    Thank you for your excellent response. I've been modded into the ground for my first time at slashdot, probably because I used too much sarcasm without warning people and assumed that a certain amount of economic theory was general knowledge. So I'd like to add to my own entry's self-defense:

    From the fifth page of the article:
    "Such thoughts underline an important truth about collective intelligence: Crowds tend to be wise only if individual members act responsibly and make their own decisions."

    I know of no other way to "make your own decisions" than enlighted self-interest. Kenneth Arrow and Gerard Debreu have shown that an idealized free market economy can achieve Pareto optimality. Important is that most individuals rationally evaluate which exchanges produce a net benefit for themselves, and accept only those exchanges. This is, in my opinion, a clear case of swarm behavior, since it relies on individual interactions being performed based on a simple set of rules which add up to an optimal solution.

    Communism, even in its idealised distributed form cannot achieve the same results since it relies on all decision makers to know not only their own interests and preferences, but those of everyone effected by their decisions. The missing element is not perfect altruism, it's omniscience. This is, in my opinion, the reason why societies which experiment with communism end up with some kind of authoritarianism -- people are more willing to believe that a few elite have the knowledge and intelligence to make optimal decisions than that the masses do. It's just the more extreme version of the "there should be a law" camp.

    For more information on Pareto optimality and Pareto efficiency, as well as some fair criticisms for using the principle as an evaluation of economic outcomes, check out wikipedia: http://en.wikipedia.org/wiki/Pareto_efficiency

    I'm not sure what you mean. Communism's other name is "command economics". It's the idea that some wise and benevolent leader is better at allocating resources than a pack of ravenous self-interested capitalists. Combine that with the idea that an elite, educated few are better at choosing a wise benevolent leader, than an unwashed mob of drooling voters, and what have you got?

    The idea that there is a net benefit for a group from the collective selfish actions of individual actors is closer to what this article is describing as swarm theory. It's also a reasonable description of democracy and free market economics. Both are ideas which I kind of like.

  6. Re:insurance is not a charity on Bill To Outlaw Genetic Discrimination In US · · Score: 2, Insightful

    I essentially agree with you, but I'd put it differently. I heard a quote on the radio a couple of years back from some representative of the insurance industry which went to the effect of: "We're okay with not having your genetic information, for as long as you don't have it either."

    Basically someone who knows they are going to die or be disabled soon would pay for the insurance. Once the customer is making decisions based on that information, the insurance company will be forced to raise prices to cover their extra costs which result from paying out on someone like that. But that's not the end of the story. When the prices are raised, people who know they are very unlikely to die or be disabled soon will stop paying for the the insurance and look for alternatives. This worsens the risk distribution for the insurance company even more, forcing the prices up further.

    Eventually the price of the insurance will be a realistic reflection of the real costs of whatever problems it's supposed to cover. Once that occurs, there's no reason to pay for insurance at all, since you can just as easily use a savings account. At that point there is no insurance industry for that problem anymore.

    It boils down to a fairly simple general principle: when a negotiation is occuring between two parties, the party with more information has an important advantage. At some point the disparity becomes so great that it's not even worth it for the disadvantaged party to accept a negotiated agreement at all. That can be bad for both sides.

  7. Re:Some facts to back up your opinion please? on Treating the Dead · · Score: 2, Insightful

    I doubt though that people base decisions about how healthy their lifestyle will be on the question of whether or not someone will pay for their illness. After all, most of us like being healthy regardless of how much or how little money that will cost us. This is one of the arguments *for* socialized health care. It's not like in other industries where people will shop around for the best price/quality quotient. They want the best possible service, or the quickest possible service, but rarely the cheapest possible service. This is one reason that it is reasonable to call healthcare a "natural monopoly" (like water, sewage, or electricity). There are good arguments to be made for saying that health should be taken over or heavily regulated by the government.

    Still I'm not convinced.

    Where economic incentives do help with a market-based health insurance system is when employers have to pay for health insurance (as it is in most cases of full-time employment in the US). I suspect that the most important component of your lifestyle is what you do at work. By forcing employers to pay for health insurance, you provide an incentive for employers to provide a healthier environment for their employees since that means lower insurance premiums. Results of this that I've seen are: company cafeterias with a greater emphasis on also providing healthy food, on-site exercise centers, and improved emphasis on ergonomics and safety.

    I also think that Europe's social, and physical structure works better for keeping people healthy: less relocations and more vacation mean less stress and more contact to friends and family, denser cities and better public transportation means more exercise, less wealth means less excessive eating. I don't believe that socialized healthcare is the primary factor in the health gap between the US and Europe.

    In addition socialized healthcare has negative consequences which I have had to directly bear. My old doctor closed his practice because he couldn't earn enough to support himself and his family. My new doctor is great; I'm really happy with him, but the appointments are very short -- he's obviously over-worked. It's problems like this and others that have brought me to opt out of the German socialized healthcare system.

    P.S. In Germany you pay between 12-15% of your salary for socialized health care. I'm not going to compare that to the US, since I don't actually know the percents in the US. I'm just putting that out there for anybody who does know the US number and wants to compare.

  9. Re:Oh, great on FDA Considers Redefining Chocolate · · Score: 1

    I've never been a twinkie fan, and I don't drink sodas. Those are a part, but not the whole of the picture on American foods. Like I said, I spent the first 22 years of my life in the US. Of course it could be a sub-culture thing, in which case my comparisons are bad. Still, here they are:

    My own mother never in her life added sugar to peas or carrots. She rarely added sugar to strawberries. But Germans seem to consider not adding sugar to these things weird. In waffles and pancakes my mother and now I measure sugar with tablespoons and not cups. I can show you in the measurements that the German cake and pie recipes I have contain considerably more sugar than the American cake and pie recipes. I'm talking here about home-made food and not manufactured food. None of that added sugar makes the things it is added to taste better in my opinion. The presence of it also makes the difference between feeling good after a meal or not.

    Of course that's just the sugar side of thing. We could expand the topic to simple carbohydrates. A month ago I had an eye-opening experience. I wanted to improve my nutrition, so I read a book in which they suggested buying whole wheat bread instead of bread made from refined wheat. I thought "No problem. I'm in Germany, the land of the corner bakery. Some of those hundreds of different kinds of breads will certainly be made with whole wheat." Boy was I wrong. Nichts da. Not one was whole wheat. All the so-called gray breads were a mixture of refined wheat flour and rye. I've been bragging for years about German bread, and now I have to eat my words. I can't even find whole wheat flour or a whole wheat bread mix at the grocery store.

    If we take it from there up to general diet healthfulness, I was raised to use sunflower oil and olive oil for most of the things I see Germans using butter for. The butter doesn't seem to have any flavor advantages, but it isn't as healthy as plant-based fats. In the trans-fats category, they are at least starting to talk about forcing labeling in the US, where Germans are apparently not even aware of the problem -- I haven't been able to find one who can translate "trans-fats" or "hydrogenated" for me. Based on its ingredients list and its consistency, I'm betting Nutella is mostly a German rendering of Crisco, but I have no way of finding out. Continuing from there, lots of German food, especially meat dishes, tastes over-salted to me. Germans drink statistically about twice the amount of alcohol that Americans drink and apply social pressure in a much more aggressive manner than Americans in drinking situations. Germans encourage over-eating by finding it socially difficult to accept leaving food uneaten on the plate, or taking it home with you. I've been in several German households where they'll help you to seconds of food or alcohol even after you've said "No thank you". One German woman even went back into the kitchen to cook extra without asking and then tried to force the food on me. "Coffee", that late afternoon meal which consists entirely of cake is also unhealthy.

    On food safety, Germans eat many more foods raw which are dangerous in that form (tiramisu with raw eggs, mett with raw ground pork and hamburger mixed with raw eggs). Two acquaintances of mine got Salmonella that way. Nobody I know in the US has ever had Salmonella. German grocery stores don't refrigerate their eggs, and they sell milk much closer to its expiration date. Because it is difficult for her to throw food away, I can't convince my mother-in-law not to feed food containing meat which sat at room temperature overnight to the chickens she gets her eggs from. I've never gotten spoiled meat from a grocery store or a restaurant anywhere other than in Germany.

    I think the only reasons German health and life span statistics aren't as miserable as Americans is that they get more exercise.

That means you have to make sure you've compiled with exactly the same version of the stl with all the components of your program which accept and pass strings. This in turn makes it impossible to release different parts of your program separately from each other if you are using the stl at the interface between your components.

    There are a couple of solutions to this problem:

    1.) Pass character arrays at the interfaces between your components and immediately put those character arrays under the control of your library once they come in.
    2.) Write or find your own string library and pass that string class between program components. Be careful when doing this. Mistakes will come back to byte you.

    All of it's kind of nasty. It'd be nice if C++ could standardize their binary representation, even if it's only a standard valid per platform.

    Then there's also:

    3.) Choose a language which unlike C++ already has a standardized binary representation for strings, or a system global interpreter for a varying binary representation. This is just an extension of the "higher-level library which does the memory management for you" option really.
