Neo Feudalism

So…This blog has been up for about two years. I have subjected you to a couple hundred posts; some way too long for a blog. In that time I’ve also gotten a couple hundred comments; though almost half were from one delusional Serbian. My tracking scripts show that the blog has garnered around 25,000 hits. Some people have spent hours reading over the content I’ve written up.

Mostly this blog has been evidence that I’ve got something to say, and I can say it. I cannot emphasize enough how the idea of an audience has shaped my message of love and humanity that I type into a void of electrons. Sure I’ve gotten a lot of personal flac and support from those who know how to contact me directly, but those are from people who have every invitation to exploit their treasured position in my life. Most of you have read this in spite of who you might be to me, and I should take the time to let you know that you are precious to me also.

Why this outpouring of gratitude? It does not mean that I’ve discovered where you live and have been stalking you. I will not show up at your work with a mangy puppy and a look of threadbare delirium pleading to borrow your used socks. A cup of coffee would be nice, but only for your company. I digress.

I have been struck by changes in the US political and economic system. It was not the OWS movement that initiated my concern, but it got me to thinking about doing something about it.

I’m thinking about lending my squeaky little voice to the idea of re-instituting progressive taxation and instituting universal healthcare in the US. This blog would suffer.  

"Cowards die many times before their deaths; The valiant never taste of death but once." -- Julius Caesar, Act I, Scene 2 William Shakespeare

 I do so like writing love notes to the wind; knowing there is no invisible deity to intercept them, and prevent them for getting to you.

Whoever you are.

Flat Earth Darwinist

I am a lucky enough person to be able to run during my brief lunchtime at work. I enjoy more than simply the luck that comes from realizing the grace of a tolerant work environment. When I run I escape into a wilderness where the curvature of the earth can be seen over dry land. Buildings, and for that matter anything manmade, refuse to contaminate the horizon. I can see forever, and then the world simply ends. If I were inclined to be a flatlander the scenery through which I run could be used as stark proof for my beliefs.

I am not inclined to believe the earth is flat. It is true that before I escaped puberty the first grainy images of the earth from space were popularly displayed. It is true that many hundreds of years before I was born the idea of a flat earth had already been largely discredited. Maps and globes that proudly displayed a spherical (or pretty darn close to spherical) earth were the standard means of representing our planet for a very long time before I ever saw one. Yet, if we go back in time far enough, we will find people who honestly believe that the earth is flat. How can this be?

When I look out to the edge of the earth I know there is something beyond it. When I look out to the edge of the earth I also realize that it is just not all that far away. When I put the farthest thing I can see in reference with something, like a mountain or a big rock, I realize that the earth disappears at a distance I could walk to in a day. It would be a really long walk, but the distance is easily grasped. When I try to think of the distance between earth and Alpha Centauri I become dizzy from the use of unimaginable orders of magnitude. When I try to think of the horizon I am ticked with the idea that a good marathon runner could span that distance in a few hours, and that even I could run it in just a couple hours longer than that.

The Marathon derives its name from a historic battle fought in the summer of 490 BCE. Around that time there were supposedly large numbers of people who thought that the earth was flat. Not only did Pheidippides run farther than the edge of the world, but the battle of Marathon itself was against an enemy who had traveled in ships from a distance many times greater than the distance to the edge of the world. If the ancient folks really believed that the earth was flat then the whole “falling off the edge of the world” element was probably not so important. There must have been some set of explanations for why the horizon existed which were sufficiently untestable that they filled the need for explanation. The edge of the visible world could be explained away as an annoying phenomenon; deal with it and move on.

The reason we can be so easily convinced that someone like Pheidippides thought he was running on a flat earth is that we can easily see how a flat earth theory works. When we build, conceive of distances, or do most any mundane manipulation of geospacial coordinates we can treat the earth as flat with impunity. Most of our lives can be productively spent treating the worlds topography as an “I don’t care”. Though modern civilization has created many thousands of activities that require the realization of a spherical earth most people would be unaffected if they were forced to believe that the earth was flat. How could you force them to believe such nonsense? How about threatening them with something nasty…like eternal damnation? Just get someone to write a book, or pretend to discover some hidden plates which have the flat earth gospels on them.

You may think I am being mean spirited in suggestion of even imagining pulling off such a whimsical intellectual falsehood. What good would it do? Hmmm…let me think about that one.

Isolating a large group of productive individuals on the basis of self-limited understanding of the universe might produce a useful well-defined cadre of like minded individuals. Here you would have a cluster created by mutually supported gullibility. What else would they believe? What lengths would they be willing to go to in order to protect the underpinnings of their mutually held delusions? The flat earth gospel would be an effective screen for ideas that might disrupt the cluster. Belief that the earth was round would be a good indicator of the potential presence of other contaminating ideas. Converts? Converts are great! If you can really be convinced that the earth is flat you should be able to be convinced of anything!

I think that the potential use of flat earth ideology is too damaged by centuries of contaminating thought to be of much use. It would be better to find a gentler, softer, less invasive concept to use as a ideological filter. Racism and nationalism have been used to great effect, but by design they are limited in their scope. A scientific concept would be best. One that has only been around for a few hundred years at most would be ideal. The concept should have little impact on most of the population if it is abandoned, but should be sufficiently well known that people can actively discredit it.

I know just the one:

Placebo Effect

The use of placebos in the clinical treatment of disease conditions would appear to be a no-brainer. Since the pioneering work of Henry Knowles Beecher, and his defining paper of 1955, the placebo has been a concept of great note. The placebo (Latin: "I shall please") effect is the production of a measurable response to a medical intervention which has no physically therapeutic elements. The placebo effect has been observed with drugs (sugar pills), surgeries (sham interventions), and psychotherapy (lies). The unifying feature of placebos is the misinformation given to the patient; they are told they are receiving competent medical intervention when they are not.

The idea of lying to patients in order to improve the prognosis of their treatment raises all sorts of moral questions. There is a lot of literature discussing these moral dilemmas; this entry is not part of that discourse. I try to avoid writing about morality except in cases where I want to. However, one can imagine how a potentially powerful positive effector that just happens to be a great excuse to lie gathers more support than a simple treatment that does not encourage untruth. Some of that collection of untruth concerns claims of the effectiveness of placebo treatments.

The idea of a strong placebo effect has survived for decades with only sporadic targeted examination. Placebos are typically used as negative controls in medical tests; there are rarely placebo negative controls. The placebo effect is usually examined relative to a generalized out-of-test population. Over the past decade the placebo effect has been more carefully examined. The results are interesting.

1) Placebos do not cure cancer or set broken legs.
2) They are generally ineffective in situations where a clear binary (either cured or not cured) outcome is clearly defined.
3) They are good pain relievers, causing an almost 7% decrease in perceived pain.
4) They only work against pain in 35%-40% of most populations.
5) They are wildly effective in some people.
6) They are effective anti-depressants.
7) They are much better than no treatment for many psychological illnesses.


These data suggest that claims of disappearing kidney stones and vanishing brain tumors are no more common after lying to a patient than giving them the straight dope. On the other hand the severity of the pain caused by passing the kidney stone can be reduced with lies.

The conditions most demonstratively affected by placebo use are those with a neurologic component. That the brain can change itself is a repeating motif of this blog.

The questions of how the benefits of a placebo effect can be more robustly applied to susceptible conditions is worthy of more intense examination.
