  1. Re:If I could do it, I would! on What the Top US Companies Pay In Taxes · · Score: 1

    Go ahead, people, cheer for the corporations. None of them are doing anything for you. Your government supplies your drinking water, builds your roads, responds in the event of disaster, and much, much more.

    I believe as far as entities go governments are also the leading executors of genocide, war, religious oppression, institutionalized discrimination, etc., etc. At least corporations aren't ever going to be interested in the wholesale extermination of large segments of their customer base.

    Not that I am particularly interested in having corporations exist with comparable powers. The short and simple rule is that the more power something or someone has the more despicable it becomes. But there is no getting around the fact that there is a lot of power to be wielded one way or the other. You can't simply declare it to be void. So the best you can do is to try to keep it divided against itself.

    Thus, a divided government (legislative vs. judicial vs. executive; independent states; competing political parties; et al.) is better positioned to be free than an absolutely monarchy. And functioning capitalism promotes more freedom than monopolies or communism.

    Where monopolies have cropped up I am all for seeing them removed. Especially when their existence is the result of direct government sponsorship.

    However, I persist in the (so far historically correct) observation that government is the most dangerous entity, and I am very happy to have a great deal of its power divested to private entities, companies or otherwise. It worries me to see such extreme views as your own... with such an attitude you can justify anything. We should check the power of corporations without making it into a holy crusade. I realize they are a nice soft target for ideological grandstanding, and in the end they are certainly an imperfect instrument, but probably having them around is the less terrible than many of the alternatives.

  5. Re:only in medicine on Science and the Shortcomings of Statistics · · Score: 1

    Looking at my school's course catalog, I'm not sure where people in any of the hard science programs would be getting this kind of knowledge. Even the probability course--which students grumble about if they have to take instead of the "easier" statistics class--is not that in depth. There are too many areas to cover in a single semester to focus on ironing out all the "gotchas" rather than simply introducing the core material. And no statistics related courses are required beyond that one class.

    In other courses professors are rather more intent on teaching their own material. They'll teach t-tests, etc., if they have to, but not at the depth which would address the problems described in the article. In my experience the physics department has been the only place where they don't play fast-and-loose with mathematics in general.

    I think you probably have less problems in the published research of the hard sciences in that that is often interested in applying an actual theoretical model. Misapprehending the finer points of the statistics involved is not as relevant as it is when you are just datamining the genome for any correlation you can grab at.

    Will a healthy "non-donator" be put far behind, for example, other persons likely to die/reject the transplant? If the free-loaders are a small minority one would think it would be better to keep the emphasis on getting organs to the people who stand the best chances of being able to use them, rather than necessarily who has put in an equitable stake.

    For that matter, although these people may not have volunteered their organs, if they pay taxes they are still contributing to Israel's socialized health care program. How much does that count for sharing the burden of these expensive procedures?

    And will these people still have a reasonable chance of coming up on the waiting list, or are their prospects pretty much nullified? Seems to me that death is a bit harsh of a penalty for not signing up. You may as well just void the opt-out bit entirely. Surely you would rather they be annoying whiners about it than potentially dead.

  11. Re:The Irony on Beliefs Conform To Cultural Identities · · Score: 1

    Bias is affecting the experiment even before it begins--hypotheses are made based on human intuition, and experiments are selected based on judgments of value. Historically, look how long science lagged in the same state simply because people didn't think outside of what they had come to expect. Even post-Newton, if it wasn't for chance discoveries--for example, Hertz' observation of the photoelectic effect--one wonders if the human mind would ever have ever dared to venture speculations beyond the 'sensible' mechanisms of classical mechanics. It's not a simple thing to divorce your expectations from the form the science has previously taken.

    In any case, I was more specifically interested in the environmental aspect, as it was a central consideration of the article. Climate science (certainly at this stage of its development) does not quite lend to your criterion of "experiment, rinse, repeat." There's not really any experiments that can be run to analyze the sum nature of the system. At best you can confirm small elements of what is going on and try to incorporate them into an approximate model, which is speculative and requires many assumptions. There's also the matter of when certain results contradict other results, and you say "the sum of the evidence says this." But it is a weighted sum, obviously--there's no guarantee a slight discrepancy in one place doesn't represent a fundamental flaw in the model. Beyond that, there is the issue of understanding what the science you're testing states--how much is the methodology based on expectations?

    If we accept the study's conclusion that people, when presented with actual facts, tend to select, discard, and reason around them based on their cultural identities, one would imagine a bias in cultural identity could infuse a bias into their net understanding of these statistical considerations. In which case, we may need to examine those biases before coming to such conclusions as "between the 90% and the 10% positions in field X, the 90% position is most probably correct by reason of being a greater proportion." What if that simply represents a proportion of personalties?

    Not commenting on the debate, but I think it's interesting that in an article about cognitive biases (particularly group cognitive biases) that they don't ever bother to probe the question of how such biases affect things like "scientific consensus," they only view it from the perspective of how such biases affect the freshly germinated views of the uninitated. You would think scientists, being human beings as well, would be in some way subject the same effects, and as long as questions are being raised about the human proclivity for certain viewpoints, someone might stop to wonder "in what ratio do people who go into the environmental sciences tend to be individualist or communitarian, and how is this likely to affect their judgment of related information?"

    It's easy to ridicule people as paranoid. Instead, however, you should be thinking "why the heck are they requiring my fingerprints".

    What I am comparing this to is, for example, using a social security number for identification, which seems to generate a large current of opposition here on slashdot precisely because it such a non-physical, easily reproducible security feature. I want anonymity as much as the next guy, but the one place I don't want it is in verifying my identity.

  14. Re:And keep the government off my Medicare! on State of Alabama Fighting NASA's New Plan · · Score: 4, Insightful

    The problems with your argument are as follows:

    (1) "Mayor Tommy Battle" and his "task force to include 25 community leaders" does not equate to Alabama congresscritters, Alabama citizens in general, or the tea party movement.
    (2) Nor do I really think if we took a poll of Alabama's citizens that we would find a majority who thought Obama was "fascist" or "communist".
    (3) So far I haven't found anything definitive about Mr. Battle's political affiliation... maybe someone else can make a more skilled research. But the best lead I have is that he spoke at a conference for Democrat women. It may be the case your assumption he represents conservative groups is incorrect. Was it substantiated by anything other than seeing the word Alabama?
    (4) Promoting small government does not preclude people from supporting the existence of certain government programs. I mean, theoretically you are talking about conservatives (or some crude caricature thereof), not anarcho-capitalists. As "the Alabama task force fighting the new plan includes former NASA Administrator Mike Griffin and former Ares project manager Steve Cook," I think it there are probably some decent balancing arguments for maintaining the program.

    Unmanned spaceflight isn't exactly justified by the costs, either, assuming we're only considering the utilitarian value. If things like learning Martian geology etc. are useful at all, it's certainly not in the short term.

    However, I don't particularly care about simply optimizing every ounce of resource over the course of humanity's multi-million year future, or whatever it may chance to be. I'm looking at, say, 70 more years of life, and if it all at possible I want to see the Mars landing and semi-viable space colonies. Probably not going to happen, but as one of the people who is taxed to fund this program, I'm just putting in my vote.

    Anyway, while it would be inordinately pleasant to convince ourselves that Obama just wants to see NASA's resources used more effectively, let's not kid. It's not like this idea is coming attached with any extra funds (such as would say, "I think this is a valuable effort"), and congress's unfailing habit has been to slash NASA's budget. If, as you say, the manned program is "pure pork and nationalism," well, what do you think is going to happen to our space program without those incentives for funding it? Is congress suddenly going to realize the value of pure research? Nah, they're just going to view it as an even more tempting piggy bank for when they want to bail out banks but also want to pretend they have some vague notions about balancing the budget.

In fact, if the explosion pressure is more than the water pressure then the increased water pressure actually decreases the maximum net pressure the barrel needs to be capable of withstanding.
