The stress placed on the test subject in blind tests or any tests depends on the pressure applied. For example The Amazing Randi applied lots of pressure on potential test subjects, even when the device that was the device under was an audio cable or tweak. Fremer was the victim in the Randi Million Dollar Challenge to hear the difference between super expensive cables and some generic cable. A customer of mine was the victim of the Intelligent Chip Million Dollar Challenge.
What are the negotiations involved for Randi’s blind tests? The negotiations themselves produce stress. Choice of test system. The number of test participants. Test protocol, usually involved the requirement for ten consecutive positive test results. Also, the choice of test software, choice of location of the test. Gentle readers, are these requirements or negotiations not cause for great stress when $1 million and or reputation is at stake?
Yeah, prof, I’m the one muddying the waters? Give me a break! That’s exactly what pseudo skeptics charge when someone challenges their dogmatic beliefs.
prof has scrupulously avoided responding to my main point - that negative results of blind test cannot be generalized. You cannot say that because a blind test result is negative that means the device under test doesn’t work or that there are no audible differences between any two cables, or between two fuses, whatever, being compared. A test is only one data point. If there were ten tests by ten different people or groups in ten different systems and most of the results were negative then you might have something to talk about.
