Evidence is not proof. That’s precisely why one test proves nothing. Preponderance of the evidence requires multiple tests as I be already said at least twice. To be strong evidence a test must be repeatable and transferable.

You’re not paying attention. If there is something wrong with the component you throw the whole test out. It doesn’t mean anything. It’s simply one of many things that can go wrong with kind tests or any tests. That is why tests have to be repeatable and transferable. One test doesn’t mean anything.

Well, for one thing blind tests are used for a number of reasons, including testing a single component or audio device or tweak. So don’t hand me a whole load of horseman knew her. Furthermore, if there is a problem with a component and it flunks the test, the test result is negative, not a “false positive” as you claim. Follow?

In addition positive results of blind tests of cables, tweaks, hi res vs Redbook, etc. are vanishingly rare because of all the things that can go wrong as I already pointed out. There is also the issue of the person’s hearing ability or skill or experience. But I wasn’t going to go there. 😬

@geoffkait not quite, it is also possible for bad test design or mishandling to effect one component and not another, so a positive can also be false.

>>>>But that case would be a negative result, not a positive one, for the component that was mishandled. That falls under the heading “error in system.” It wasn’t a false positive, it was a negative. I only gave two examples of things that can go wrong. Obviously there are many others such as operator error, unfavorable weather, system not revealing enough, cables or components not broken in, etc. In any case, this highlights why it’s important for multiple blind tests to be performed on multiple systems by multiple testers. 

The main problem I see with blind tests is that negative results from a single test have very little meaning or significance since there are so many things that can go wrong with a given test. E.g., the tester could be all thumbs or the system could be miswired.

Positive results for a single test, on the other hand, are more credible since positive results were obtained in spite of any problems or errors that may have occurred in the test. As tests are repeated in the same system and are performed in other systems independently results begin to have more meaning and credibility.
