Opaqueice, Is perhaps one of the confusing things in this discussion the difference between a single person, single trial negative result (i.e. null) vs a single person multiple trial negative result/positive results vs multiple person multiple trials?
When someone says "I heard a difference", I believe totally that they believe they heard a difference. The issue is that there are many ways people can perceive difference that is there, but not they way they think, or they perceive difference that is not there, but they have been suggested into thinking it is there. For example, someone who "got better" in a DBT of a drug *is* better. But the drug is not necessarily causitive. If it does not show efficacy in the statistics (i.e. over many people and trials) then the "got better" result was not due to the drug. Similarly, people think that changing something (e.g. an amp, a source) is the cause of a "got better" result. It could be many other causes, e.g. volume not matched +-0.1 dB (louder is perceived as "better"). So the issue is determining if a given change "caused" the "got better" result, not whether they heard an improvement. Maybe I am not expressing this well enough and you could eloborate or say it better. The point I am making is that many people feel offended when someone says "it got better" and "thus it is due to X" and someone else says "did you ABX it" - they interpret this to mean that the ABX comment means they did NOT hear an improvement, and that their conclusion the improvement is from A (which is what they changed) is wrong. The former may be true: they heard it. The latter may NOT be true, unless the statistics show that A is in fact causitive above the level of random chance.
