Comment p-value research is misleading almost always (Score 5, Interesting) 208

I studied and tutored experimental design and this use of inferential statistics. I even came up with a formula for 1/5 the calculator keystrokes when learning to calculate the p-value manually. Take the standard deviation and mean for each group, then calculate the standard deviation of these means (how different the groups are) divided by the mean of these standard deviations (how wide the groups of data are) and multiply by the square root of n (sample size for each group). But that's off the point. We had 5 papers in our class for psychology majors (I almost graduated in that instead of engineering) that discussed why controlled experiments (using the p-value) should not be published. In each case my knee-jerk reaction was that they didn't like math or didn't understand math and just wanted to 'suppose' answers. But each article attacked the math abuse, by proficient academics at universities who did this sort of research. I came around too. The math is established for random environments but the scientists control every bit of the environment, not to get better results but to detect thing so tiny that they really don't matter. The math lets them misuse the word 'significant' as though there is a strong connection between cause and effect. Yet every environmental restriction (same living arrangements, same diets, same genetic strain of rats, etc) invalidates the result. It's called intrinsic validity (finding it in the experiment) vs. extrinsic validity (applying in real life). You can also find things that are weaker (by the square root of n) by using larger groups. A study can be set up in a way so as to likely find 'something' tiny and get the research prestige, but another study can be set up with different controls that turn out an opposite result. And none apply to real life like reading the results of an entire population living normal lives. You have to study and think quite a while, as I did (even walking the streets around Berkeley to find books on the subject up to 40 years prior) to see that the words "99 percentage significance level" means not a strong effect but more likely one that is so tiny, maybe a part in a million, that you'd never see it in real life.

I travel a ton and stay in dozens of different hotels every year. Domestically, and in maybe 50% of the foreign cases, the high priced hotels had worse and slower internet up until a couple of years ago. For the last 2 years they have gotten better, on the average. Oh, I was in a 5-star Vegas resort last night that had horrible bandwidth. In the past, my joke was accurate that the difference between a Four Seasons (just an example) and a Super 8 is that at the Super 8 the internet worked and was free. The most important thing to me in a hotel is computer use. The fancy suites in major hotels are often set up for entertaining friends and DON'T even have a computer desk. I ask my wife to book me into Super 8's whenever possible.

End goal: change the constitution. We need a start. It's easy to see how hard this will be and to give up early, but some of us feel the imperative to fight for it. We can change things. The vast will of the masses (corporation political donations are not equivalent to the free speech we enjoy as individuals) needs to be strategically gathered. Critical mass could take decades, as with things like gay marriage.

You missed my point: there are literally thousands of powdered supplement mixes out there that contain all different types of blends/mixtures of various compounds, minerals, vitamins, amino, etc. there are even some that have whey, soy, casein, etc. as part of the blend.

As a company providing APIs and encouraging development on your platform is great as long as you maintain control. The problem with APIs is apps can, provided the APIs provide enough of the right data, totally remove your influence in favor of the developer using your APIs. I first saw this Social Fixer app a few weeks back and I immediately thought "finally, someone that will remind us who owns facebook: the users." Facebook will have no revenue if they cannot monetize the marketing of their site, and with free APIs they can't do that. Paid APIs? Devs want free access, so you'll kill your dev community if you start charging.

That's expensive. "Cloud" hosting services cost about 1.5x traditional hosting. When you want multiple locations("regions" in aws) you need to pay for resources in each additional region, then pay another cost to provide that failover. Cloud hosting is great, but it's nothing it does is new or cheaper than hosting 10 years ago.
