    Fair enough, provided that funding for repairs is *guaranteed* meaning that even if a catastrophe is due to gross negligence or intentional sabotage, some combination of insurance and company liquidation will still cover it.

    Sure, but allow the insurance company to sue the oil company for the damage afterwards if they can prove negligence or intentional sabotage. The cleanup will be paid, and the culpable parties will be punished (eventually, if culpability can be proved).

    And that the insurance company has to be able to cover their liabilities even if several unrelated catastrophes occur in the same bad year.

    That's already a problem with insurance now, and it is handled by reinsurance. If the probability of oil spills are not linked (and I don't think they are, but please enlighten me if I am wrong), it shouldn't drive up the price of insurance too much.

    [...]we'd be siphoning a pretty huge amount of money out of the system, so I don't know that it would actually improve anything.

    Don't think of it as siphoning, think of it as paying to a reserve that covers the cleanup of any spill. Sure, there will be an overhead, but putting all of the money needed in a reserve from day one would result in opportunity cost, so I don't think it will be much more expensive (assuming functioning markets in the insurance business, but between companies, I don't think that's much of a stretch).

    As the AC said, you are interpreting the frequentistic concept of p-value in a Bayesian framework. I think it says something about frequentistic probability theory that its most famous concept is confusing except if it is explained in an incompatible framework.

    Three sigma. As in .001 probability that the null hypothesis is true despite our sample observation.

    No, 0.001 probability that we would observe this, or worse, if the zero hypothesis were true. In order for it to tell anything about the probability of the null hypothesis being true, you need to include the probability of the null hypothesis being true before we made the observation.

    The oil in the ground is undigested because there is no oxygen present, not because it takes a long time to digest it. n-alkanes, some of the most abundant compounds in oil, are the ones that are eaten first by bacteria once the oil is in the environment.

    No corporation may engage in any activity in which the costs of repairing any public/environmental/etc. damage from a worst-case scenario cannot be covered by liquidating company assets.

    This will severely restrict the number of companies who can work in any given field, leading to lack of competition and all of the inefficiencies that follows from that.

    Why not allow the companies to take out insurance for such events? That would (ideally) make the payment scale directly with the risk of failure, so that new companies can start a small operation without massive investments, and so that companies that have bad policies are punished for having the bad policies, not for the failures that these policies cause.

  7. Re:Consequences... on Oil From the Exxon Valdez Spill Still Lingers On Alaska Beaches · · Score: 2

    The problem with this strategy is that you are restricting who can realistically go into the petroleum business, and thus restricting the competition. Perhaps forcing the companies to have a insurance to pay for cleaning up would be better? That would scale with the size of the operation, so it wouldn't force a oligopoly, while companies that did too little to safeguard their operation would be punished by higher insurance rates.

    Especially, flammable tap water.

    Great, an example of flammable water where they actually have established that something has changed. This puts it leaps and bounds beyond most such claims.
    However "the amount has changed" is not a proof that it is caused by fracking (correlation and causation and all that). It would be pretty easy to measure the amount of C-14 in the water, which would immediately tell whether it is old methane or methane from recent biodegradation. Until such a test has been performed, this goes in the "interesting, but not conclusive" category.

    It is quite often one of the problems of medical papers. People are different, and you can always find another way to split up the groups. What if you only look at males? Aged 20-30?

Furthermore, there are a lot of diseases that people can have, so if you are doing a observational study, even eating multivitamins doesn't change the incidence of cancer in 20-30 year old males who eat a moderate amount of broccoli, what about the incidence of ear cancer?

    So it does. Well, and dropping again, now. But that is to be expected, and I agree that it will at least stabilize soon.

    With regards to the bubble, more than a doubling in price within a month seems to predate most large falls in Bitcoin, so I will consider that a sign of a bubble. From the November 1st to December 1st, the price had pentupled.

    The declaration from China came in the middle of a bubble. In my analysis (yay, random internet guy analysis), it seems as if that drop was not because of any direct impact of the declaration, but simply came because enough people knew it was in a bubble and was simply waiting to sell as soon the bubble seemed to burst. The declaration acted as a signal for the end of the bubble.

    Oh, and it seems to keep dropping.

So in stead of having a somewhat safe system, I now have a completely unsafe system. Oh, and my password space has gotten much smaller, because your system is already far too big a burden without me having a password longer than absolutely necessary.

    Assuming you are talking about Chinas move in the start of December, Bitcoin was clearly in a bubble at the time (the price had risen a factor of 6 in a month). Bubbles are notoriously vulnerable to any signal of the end of the bubble, so we really can't say that this behavior is general. Do we have any non-bubble examples of substantial, sustained drops in the value of Bitcoin following government intervention? Just to put some concrete numbers on the concepts, let's say a bubble is when the price have more than doubled in a month, a substantial drop is more than 20%, and it is sustained if the drop is still there a week later (but feel free to criticize these numbers).
