Correct. Even if you specify your subgroups beforehand in the experimental design, you still need to modify your interpretation of statistical significance (downward) to account for the consideration of multiple hypotheses. If you're going on a fishing expedition by identifying subgroups post hoc, then you ideally need to base this correction on the potentially large number of conceivable subgroups that are available to be drawn. It's very hard to achieve real significance under those circumstances. On the other hand, you might find a subgroup result suggestive and conduct a separate follow-on study to test it independently; that's perfectly legitimate.

A lot of people are still running Windows XP (and earlier) for much the same reason. It works as well as it ever did for them (not considering the security issues), they've acclimated to it, and who knows what may go wrong with an update? Will their old familiar apps still work, or will they have to shell out hundreds of $$ to update those too?

...it's the momentum that keeps people choosing this crapware.

Unfortunately true. It causes most people a great deal of anxiety to acknowledge there's a problem and that there are things they can do to mitigate it, because that means they have to learn about those things, which they fear will be outside their experience and abilities. As long as they're in the same boat as their friends and family, they feel the safety of numbers and can ignore the issue. The FUD mantra against Linux has always been that you have to be an elite geek to install and use it; of course that's nonsense but people believe it. It creates a lot of fear and trepidation that they'll be in over their heads if they even try, and so they don't.

I have no knowledge of the particulars in this case, but lobbying isn't even really necessary. It's often just the revolving door: The procurement people on the government side now have very lucrative careers in the private sector to look forward to, and that is something you can never get by going with the open source solution. But who knows, maybe this time they did make the call purely on its technical merits.

Comment Politics (Score 3, Funny) 98

Here we go... A relatively routine law enforcement matter is going to become a political pseudo-scandal. Scientists are evil and corrupt, so how can we trust them about climate change or evolution? Perhaps the drugs were being made at Obama's personal request. Why else would Lamar Smith be taking and interest?

Comment Part of the game? (Score 1) 152

Maybe companies like Comcast are fine with WiFi saturation. They have a monopoly on the cables in most localities, so if anyone is going to challenge them as a competitive ISP, they'll have to do it wireless. Too bad for them (and good for Comcast) if wireless connections are degraded to the point of uselessness.

Comment The perplexing thing (Score 0) 165

The perplexing thing about all of this "Obama == Hitler" spin is that (1) his main field before he got into politics was constitutional law (he taught it at the U. of Chicago), and (2) he's only got about 18 months left on his term of office. Does it make sense that he would push for greater domestic spying powers for the waning months of his own administration, when those same powers will accrue to whomever succeeds him for their full 4 or 8 years? Could there be something else going on?

My first programming class: Punch cards. Punch your deck, take it to the input window, wait around an hour or two for it to run, pick up the printout at the output window, debug. Rinse, repeat until successful. The IDE was long nights at the computing center with a thermos of coffee. Finally getting a terminal and 300 baud modem at home was a really big deal.

So you're saying that interest rates are somehow being manipulated downward to hide the magnitude of the deficit? Since the deficit is a known quantity, why would anyone take that deal? In the sane world, creditors demand a premium for assuming greater risk. If there's a stronger economy out there offering a higher rate, they'll go there in a heartbeat.

Republicans in power seems to be reflexively against anything "those liberals" are in favor of.

There's a lot of that going around, for sure, but the real issue is that science always has the potential of being disruptive to established economic interests. Whether it's Big Tobacco or fossil carbon, those interests are paying the GOP serious money for protection against these kinds of disruptions.
