  1. Re:Groupon on Groupon Could Challenge Google's Record IPO · · Score: 1

    Forbes article 6/24/2010, probably elsewhere, too: http://blogs.forbes.com/moneybuilder/2010/06/24/one-big-difference-between-chinese-and-american-households-debt/

    It does include mortgage debt. Perhaps this will suit you better: U.S. household debt is 136% of income, in urban China it's 17%. Meanwhile, more urban Chinese own their own home (85% to 69%), and those who do are far more likely to do so outright (11% with mortgage vs. 70% in U.S.).

  2. Free Market on Legacy From the 1800s Leaves Tokyo In the Dark · · Score: 3, Insightful

    FTA: "Japan's electricity system got its start in 1883 with the founding of Tokyo Electric Light Co. Demand quickly grew and in 1895 the company bought electricity generation equipment from Germany's AEG. In west Japan the same evolution was taking place, and Osaka Electric Lamp imported equipment from General Electric."

    Wait: I thought the free market solved all problems and never needed government intervention.

    Except that Texas, in its crusading fundamentalism, keeps taking over the country's political establishment -- taking the U.S. Presidency (Bush I and II), mandating national textbook standards, etc. If they were to secede then there'd be much less of a problem.

    "I have a question about 'falsifiability'. How is evolution or the big bang falsifiable in a practical sense... Or if a fossil shows up in the wrong layer or dates to the wrong time, we wouldn't say 'Aha! Evolution is wrong!'"

    Answer: In principle -- If a whole lot of that stuff keeps showing up. The concrete and testable predictions from the theory are that that won't happen.

    Agreed that in a really strictly practical sense, it's not falsifiable, because of its being true.

  7. Pedophile, Rapist, Bipolar on Students Suspended, Expelled Over Facebook Posts · · Score: 1

    According to the article, the three students in question called the teacher (a) pedophile, (b) rapist, and (c) bipolar. While many commentators have emphasized (a), I actually think (b) is a lot worse (asserts actual violent/sexual action, as opposed to mere predisposition).

    The thing that does bother me here is how the students who did (a) and (b) are honors students and were merely suspended. The student who said (c) -- the least serious accusation -- was not an honors student, and was expelled. The article also says this: "At least two of the students’ families plan to hire attorneys." Let me guess, that would be the first two students' families, because they're more wealthy and have the support to produce honors students, right? And that latter student is from a family without wealth, expelled with no legal resources, and is shit out of luck, right? (Just a hypothesis.)

  8. Re:PET/MRI and statistics are poor bed partners on Cell Phone Use Tied To Changes In Brain Activity · · Score: 1

    I actually disagree with a lot of what you just wrote there.

    I'll take one very clear-cut point -- "the corrected p value was 0.05" is false; you're misreading the abstract. It says, "Design, Setting, and Participants... P .05 (corrected for multiple comparisons) were considered significant." So that's the threshold picked in the design stage, prior to the experiment being carried out, as being significant (as you would expect). At the end, when the experiment was actually run, the observed P-value (after all corrections) was indeed found to be P=0.004. Since that's less (a lot less) than the initially chosen significance threshold, the results are declared to be "significant".

  12. Re:PET/MRI and statistics are poor bed partners on Cell Phone Use Tied To Changes In Brain Activity · · Score: 3, Interesting

    "This study involved computer based analysis using PET scan data*. Similar studies have often been shown to have overstated or no real statistical significance**. With only 47 participants this study has, in my eyes, about the same validity as the average undergrad study."

    I don't think any of those things mean what you seem to think they mean. *

    (1) On PET scan data not having "validity" -- skeptical. Citation needed.
    (2) On the linked article of science paper statistical shortfalls -- there are some good cautionary points in that article. The article does not say that similar studies have been shown to have "no real statistical significance" (in fact, just the opposite). I challenge you to point out specific statistical pitfalls (from your linked article) of which this abstract runs afoul? Because I don't see any.
    (3) 47 participants is perfectly reasonable, since the accepted number for a t-test as done in the study is considered to be 30 or more (hence generating an approximately-normal sampling distribution of sample mean results, per the Central Limit Theorem, assuming no outliers found in the obtained data). The strength of the evidence obtained is reflected in the calculation of P = 0.004 (which is super, super low, i.e., enormously significantly significant), not by your hand waving about what should count "in your eyes".

    No, it's basic game theory, specifically called Tactical Voting. The the Gibbard-Satterthwaite Theorem shows that any system must be either (a) susceptible to tactical voting, or (b) a dictatorship. Link.

    "Just because two or more candidates might be acceptable to me, doesn't mean that they're equally acceptable to me."

    Which do you think is most common? (a) Having two or more acceptable candidates with distinctly different levels of likability, or (b) Having two or more unacceptable candidates with equal levels of "I don't really give a damn". (Or at least: equal levels of "I don't care enough to spend time ranking them.") I'll bet (b) is enormously more common -- and so we should optimize for that.

    In short, most people don't have the time or attention span (or incentive) for condorcet voting. Acceptance voting is both actually feasible and a major improvement.
