You are seriously suggesting human observation is unquestionable from a scientific viewpoint? Talk about distorting stuff...

there are multiple things in observation, ranging from the characteristics of the observation and their existence. as I have stated, nothing prevents you from questioning the characteristics of the observation, such as determining the cause of the optical illusion or the cause of hallucinations. But as stated science cannot question the existence of an observation itself. If you do not agree to that then as I have asked, please present a scientific method (if one should exist) that allows an individual to question the observations made that lead to the hypothesis formed and subsequently tested (notice that the method presented earlier today allows only testing of the hypothesis not the initial observations made that lead to the hypothesis).
I think I've been fairly clear on this point. if not, as you can see, I am willing to elaborate for it is a subtle point.
I don't question that people hear differences in cables which appear to be genuine. However, I question that it is possible to formulate a testable hypothesis from these observations which relates to the physical properties of the cables, as the observations are inconsistent.
Very Nice and I do like the Chart, reminds me of my Highschool books. But I think the chart is missing something... Observing. Isn't that the first part?
The conclusion certainly leads to differences in the mind and actually the result you came up with is interesting. Has anyone ever observed audiophiles getting worse than chance? They are soo bad at determining the difference between a high end cable and a normal cable that it is not statistically close to flipping a coin?
..........
I'm gonna use this chart because I think it's pretty:
Ask Question: Do cables make an audible difference?
Do Background Research: Cable makers believe they do, and audiophiles notice differences as well ranging from increased bass to treble extension. However, what we know of electricity suggests there won't be differences.
Construct Hypothesis: Cables make an audible difference.
Test with an Experiment: Measure a number of cables' frequency responses against a control, and null the results to find the differences.
Hypothesis is False or Partially True: There are small differences, but beyond audible limits.
Construct Hypothesis: If cables do not make an audible difference, then audiophiles will not be able to reliably distinguish between them in an ABX test.
Test with an Experiment: Set up ABX tests with multiple cables of varying prices and materials, and a selection of audiophiles willing to participate.
Hypothesis is True: Audiophiles do not score better than chance when ABXing cables. This suggests the differences are in the mind.
^^^ That's what's been done so far. What do you suggest we test next?
And can I just add that comparing cables in any way to Einstein's Relativity is silly.
The theories of General and special relativity (more on general relativity than special) was "based" on the work of mathematicians and scientists before Einstein BUT his theories did not develop from them directly. The theory of General Relativity was constructed by knowing a head of time what a solution needs to looks like. If you are a scientist and accustomed to solving Differential equations, you should know that there are various ways of solving differential equations, but there are no rigid analytical methods (meaning you can just plug and chug your way through any problem and get an analytical solution). What you do instead is assume a possible solution and "test" or demonstrate that the solution is a possible solution to the problem. This is also how String theory, M Theory, etc... have been developed. So, yes the solutions are based on previously known information and as you state observed phenomena. But understand that the solutions he used for his initial special relativity were actually from "defunct" solutions from Maxwell. The reason those solutions were neglected and in fact discarded until Einstein, is because they relied on the speed of light being constant. Einstein stated, that the speed of light is a UNIVERSAL CONSTANT, in his paper without justification -he claimed that it must be so. While there were measurements indicating that the speed of light did not change (eg. Michaelson Morely (sp) experiment). Those were never actual experiments that a scientific method (should one exist) would call a proper experiment because the purpose of the experiment was different from trying to prove or disprove that the speed of light is constant. As you should know, the Michaelson Morely (sp) experiment is actually a very famous null result, they were trying to find the Aether and could not detect it. Einstein made his declaration of the universality of the speed of light as a constant in vacuum, without experimental data. He stated it must be and therefore the following physical laws follow. In fact, this is what separated Einstein from previous physicists who performed countless experiments and formulated scientific laws to govern the behavior of the phenomenon they observed. Einstein did not perform experiments.
Lots of activity since I last saw the thread, the only thing I'd add to Head Injury's lovely chart is a little balloon above it titled "The World as We Know It" with an arrow pointing to the "Ask Question" bubble, because that's where the questions come from.
What is this fixation on the notion of truth? No one that I ever worked with or studied under ever thought that the work was about the or a truth, it was about the best understanding possible at this moment in time. And yes, data are highly interpreted, how can they not be? There's no way that explanations simply leap out of collected data. Are the interpretations accurate or not? That's the important point.

The key issue here seems to be whether or not the speed of light as a constant is correct or a kludge to make things work out. All measurements seem to support the former. I guess I'm curioous why you think it shouldn't be. And no, it doesn't bother me,. There's even some research going on that suggests there may be variations over time and that doesn't bother me either. This is what science does. Mathematicians and theoretical physicists generally don't do experiments, does that mean they're not scientists? I don't think so. You need both the empirical and theoretical sides. As for Einstein making that jump, it's like the much mis-quoted Holmes/Spock statement, "Once you've eliminated . . . ."
What Michaelson-Morley did was fail to detect the 4% shift that it should have seen had aether existed. To not find a result does not make an experiment a null experiment (it happens a lot), it just means that something you thought had an effect, doesn't. All experiments test for the null hypothesis, statistically. It's part of that method.
If placebo can cure cancer, then what follows, on the science side, is finding out why. What's the mechanism for this? Is it repeatable? Can it be used for more than one person? It's not to say. "Oh, that's not real." or "Oh, that doesn't matter." People research the mechanisms of placebo, which seem to be largely the effect of conditioning and expectation. It's interesting, that placebo effects tend to disappear in clinical trials where people don't know whether or not they received placebo or the test medication.
Back to cables, you've got some information, your observed changes in your system. You've got a hypothesis, that it's the result of cables. What's not so easy to set up is a test that determines that the cables, and absolutely nothing else, is a factor in the observations.
Hey, I like philosophy and science - what more could one want from a thread?
@pdupiano
The objection against cables cannot come from refuting that observations are made as you rightly say. However, when faced with a phenomenon that some argue is not explained by modern science, the first step is to attempt to explain it using what we already believe to be true - that which has survived the vigours of the scientific method. If that is not possible, or the bringers of the objection to current scientific principles find the attempt to explain their phenomenon unsatisfactory, the onus is on them to present some form of hypothesis as to its cause, based on evidence, if they wish their objection to be taken seriously. On those grounds I suggest that believing in cables is not currently a rational thing to do. Just my position on the matter.
Also, I completely agree with you about placebo/bias/ect. It is regrettable that people tend to take such things as some kind of condescending insult, rather than understanding that such things are inherent in humanity.
I hereby declare the concept of cables affecting sound beyond a certain minimal level of cable functionality a "Myth until proven actual" (from my perspective at least)
The experiment was a null result, meaning you did not find what you were looking for. The reason I brought it into question is to call into question the validity of the results they obtained as evidence for a constant speed of light. As outlined in the proposed scientific method, you are only able to test the hypothesis that you are working with, and the results you obtained are "colored or tainted" by the said hypothesis you made since you would design the experiment to presumably obtain a particular result. Using the results of a null experiment is strange because the observed data is once again tainted by the hypothesis. I suppose an example to use is skimming text. If I want to look up a particular word or phrase, I would skim text on a page and only focus when I find the words I want to find. I would then incorporate the text into say an article only to realize later on that I took the text out of context because I had a specific purpose in mind yet and twisted the words into what seemed an altogether improbable way.
