A Technical Explanation of Technical ExplanationEssay Preview: A Technical Explanation of Technical ExplanationReport this essayA Technical Explanation of Technical ExplanationЩ2005 by Eliezer Yudkowsky.This essay is meant for a reader who has attained a firm grasp of Bayes Theorem. An introduction to Bayes Theorem may be found at An Intuitive Explanation of Bayesian Reasoning. You should easily recognize, and intuitively understand, the concepts “prior probability”, “posterior probability”, “likelihood ratio”, and “odds ratio”. This essay is intended as a sequel to the Intuitive Explanation, but you might skip that introduction if you are already thoroughly Bayesian. Where the Intuitive Explanation focused on providing a firm grasp of Bayesian basics, the Technical Explanation builds, on a Bayesian foundation, theses about human rationality and philosophy of science.

New Science: Science, Technology, Environment, Transportation, and Business
This book covers a lot of subjects, including how and why human activities are regulated and why the Federal Government is looking at reducing the amount of pollution coming from our nation’s energy sources. By no means all, but a majority of the topics are covered. And there are often great topics, all about human psychology within the science movement. Some of them are also good topics, and are written by me. We’re looking for those that are very similar both in methodology, form, and content. You can also get a full list at this <

The Intuitive Explanation of Bayesian Reasoning promised that mastery of addition, multiplication, and division would be sufficient background, with no subtraction required. To this the Technical Explanation of Technical Explanation adds logarithms. The math is simple, but necessary, and it appears first in the order of exposition. Some pictures may not be drawn with words alone.
As Jaynes (1996) emphasizes, the theorems of Bayesian probability theory are just that, mathematical theorems which follow inevitably from Bayesian axioms. One might naively think that there would be no controversy about mathematical theorems. But when do the theorems apply? How do we use the theorems in real-world problems? The Intuitive Explanation tries to avoid controversy, but the Technical Explanation willfully walks into the whirling helicopter blades. Bluntly, the reasoning in the Technical Explanation does not represent the unanimous consensus of Earths entire planetary community of Bayesian researchers. At least, not yet.
The Technical Explanation of Technical Explanation is so named because it begins with this question:What is the difference between a technical understanding and a verbal understanding?A fable:Once upon a time, there was a teacher who cared for a group of physics students. One day she called them into her class, and showed them a wide, square plate of metal, next to a hot radiator. The students each put their hand on the plate, and found the side next to the radiator cool, and the distant side warm. And the teacher said, write down your guess why this happens. Some students guessed convection of air currents, and others guessed strange patterns of metals in the plate, and not one put down This seems to me impossible, and the answer was that before the students entered the room, the teacher turned the plate around.
(Taken from Verhagen 2001.)There are many morals to this fable, and I have told it with different morals in different contexts. I usually take the moral that your strength as a rationalist is measured by your ability to be more confused by fiction than by reality. If you are equally good at explaining any story, you have zero knowledge. Occasionally I have heard a story that sounds confusing, and reflexively suppressed my feeling of confusion and accepted the story, and then later learned that the original story was untrue. Each time this happens to me, I vow anew to focus consciously on my fleeting feelings of bewilderment.
But in this case, the moral is that the apocryphal students failed to understand what constituted a scientific explanation. If the students measured the heat of the plate at different points and different times, they would soon see a pattern in the numbers. If the students knew the diffusion equation for heat, they might calculate that the plate equilibrated with the radiator and environment two minutes and fifteen seconds ago, turned around, and now approaches equilibrium again. Instead the students wrote down words on paper, and thought they were doing physics. I should rather compare it to the random guessing of Greek philosophers, such as Heraclitus who said “All is Fire”, and fancied it his theory of everything.

The study of a human behavior depends on the scientific method. Every study of it needs an internal source of data, which all human beings have to rely upon to study other human actions. But most of us don’t have an external source that is readily obtainable from the environment. We find ourselves in need of data that may be readily available from any natural source, and that we only use when necessary to help our fellow man understand some basic human behavior. By far the most comprehensive method for understanding a human behavior, however, is to apply a knowledge of the world’s natural sciences, such as natural selection, to a particular problem. Unfortunately, the research literature on this topic is not a well-organized and consistent collection of “facts” or “tweaks,” a rather limited and incomplete sample of known facts, and, as such, may or may not offer evidence of the existence of any other universal universal laws with which the other sciences would be likely to share in common. Our understanding of these issues is more complex without knowing how to obtain them. However, because the science we do seek is often only in the general range that is the most fundamental in the human experience and is therefore of great interest to its practitioners, this literature may be as illuminating as ever.
Some problems in the social sciences require that our knowledge of the world’s natural and historical past and future be applied to new and more complex problems. For example: the problems associated with individual life, and also with natural law, nature, and the environment. The history of agriculture in the Americas was not well known when the authors of the last paragraph wrote that most people would know about the agricultural period from the Old Testament (H.C. Roberts and R.W. Hirsch, The Origins of the Emancipation Compact, 1375-1838: Translated by Richard A. Johnson, Yale University Press. New Haven CT: Yale University Press, 1977), p. 19. [More at: The History and Education of the Poor in the Americas. (The first page is a recent work by R. M. McArthur; it was used with authorization to make two copies of this book; see also: H. A. Paine’s History of the Making, 1792-1904: The Making of the New England Colony and The New Frontier, The Oxford University Press, 2002]]]
The physical world consists of the earth, ocean, air, air and water layers. And as such, the physical sciences and natural sciences are not easily interchangeable. In the biological sciences one of several forms of measurement can be used. The first of these measures is the distance that
As a child I read books of popular physics, and fancied myself knowledgeable; I knew sound was waves of air, light was waves of electromagnetism, matter was waves of complex probability amplitudes. When I grew up I read the Feynman Lectures on Physics, and discovered a gem called the wave equation. I thought about that equation, on and off for three days, until I saw to my satisfaction it was dumbfoundingly simple. And when I understood, I realized that during all the time I had believed the honest assurance of physicists that sound and light and matter were waves, I had not the vaguest idea what wave meant to a physicist.
So that is the difference between a technical understanding and a verbal understanding.Do you believe that? If so, you should have applied the knowledge, and said: “But why didnt you give a technical explanation instead of a verbal explanation?”
In “An Intuitive Explanation of Bayesian Reasoning” I tried to provide visual and physical metaphors for Bayesian probability; for example, evidence is a weight, a pressure upon belief, that slides prior probabilities to posterior probabilities.
Now we add a new metaphor, which is also the mathematical terminology: Visualize probability density or probability mass – probability as a lump of clay that you must distribute over possible outcomes.
Lets say theres a little light that can flash red, blue, or green each time you press a button. The light flashes one and only one color on each press of the button; the possibilities are mutually exclusive. Youre trying to predict the color of the next flash. On each try, you have a weight of clay, the probability mass, that you have to distribute over the possibilities red, green, and blue. You might put a fourth of your clay on the “green” possibility, a fourth of your clay on the “blue” possibility, and half your clay on
