This is a good point. What does "7 out of 10 people can not tell the difference" mean? It means, during this single test (or series of tests) 70% of those selected couldn't tell the difference. It also means 3 out of 10 could or think they could.
For those that could not, we can dismiss them from future studies for the moment. Now, how do we deal with this 30%? Are we going to assume that they didn't hear anything but lied? Or perceived but were deceived? OR! might we assume that in fact they did hear a difference or perceive a difference and try to figure out how and why? Some will simply drop the argument after seeing the 70% score: "The others must be living on a placebo effect"
Yes, this could be true. No doubt it may very well be true! But it might not be so. If not so, let's adapt, propose new studies or methods of researching.
Cables might be the fun stuff to pick on (or those joy stones, quantum chips etc) but when it comes to amps or front-ends etc., there are more people who feel/believe/know that they hear a difference. How about starting here, and then working down to the level of shiny stickers?
If folks wanted to focuss on cables (since it is the hottest topic), cables being used in tests would need to be tested before hand for conductance/resistance, inductance, RFI, etc. If no differences were measured, then two or more cables could be used in a test. Merely throwing in a few brands of cables and concluding something isn't very scientific since differences, easily measured among the products, are unavailable yet necessary in a proper results discussion.
Some subjectivists certainly won't be happy with any reasonable explanation of how the world works. Others will be open minded and want to learn, particularly if the proper literature is cited. However, at the same time, some objectivists won't be happy with any reasonable explanation as to how a person might be able to hear a difference if they too walk into the experiment biased.
Will a given experiment cover all variables? No. Isolating which variables to test and then determining proper means of standardizing and testing is paramount to any meaningful outcome. If that means using blood tests, EEGs and a T-Stat oximeter to get proper basal levels for those undergoing the DBT then so be it! This data shouldn't be excluded because it is too difficult to gather or analyze. All sides should be open to discovering the truth behind their gear and how and why we enjoy music. One shouldn't necessarily have to go to insane lengths to prove a point, occam's razor and all that. However, it also means that new data being discovered ought to be considered and implemented in simpler tests before dismissing outright, someone's claims.
