What kind of evidence do you consider as sufficient?

I think it could well be, I also don't think I'm guilty of promoting any kind of religion including ABX blind testing

Sure, maybe not you but on many audio forums, including this one, there's a core of people with a religious zeal about blind tests who continually question the listening impressions of others so I did find it ironic that you should say, unintentionally, it seems "people who need to be told how to come to decisions." about what they hear
 
Maybe it´s that you missed the point in the usage of this control as the listeners do _not_ listen for a level difference, but for a difference in _sound_ .

They _don´t_ _identify_ the small level difference but they _notice_ a difference in _sound_ events.

And to identify differences or express preferences for/in sound events is exactly what experimenters do ask for in this kind of tests.

Just as a reminder, as stated quite often earlier what makes things a bit more complicated in perceptual audio evaluation is that the same impression perceptionwise is triggered (or more precisely can be triggered) by different technical reasons. A good example for this is the impression of "roughness" ; it gests even more complex in cases of multidimensional perceptual differences.

There aren´t so many ways to learn about the pitfalls of sensory testing, keeping up with the published material and do some experiments with other/different people will truly open up a new world. 🙂

Are you sure about the "same logic" argument?

Arguing is useless... I will be anyway assimilated by semantical arguments, circular logic, obscure cross referencing, scope creep, etc...

I’ve asked for an authoritative reference and was offered lip service. Let’s agree to disagree and happily live after. I still believe that positive controls not directly related to the hypothesis under test are a useless way to complicate and obscure the test results. Call me dense, I don’t mind.

Gotcha, there's a limited supply of free-thinkers the world over...just look at the state of it 😡

Obviously, if the levels are matched, which is a requirement.
They _don´t_ _identify_ the small level difference but they _notice_ a difference in _sound_ events.
Regardless of being "small", if the sound difference is there in sufficient quantity, it will be audible. Sound events when discussing audio DBT? It's such a marketing lingo use by high end audio electronics sellers.
And to identify differences or express preferences for/in sound events is exactly what experimenters do ask for in this kind of tests.
What is the kind you are referring to?

So you are not talking about audio DBT. That's what I thought.
 
Proofs only count in math and booze. 😉

Inductive/deductive is too simplistic to capture the process of science.

Facts and truth are philosophy not science.

It's about amount and quality of evidence for and against a theory/hypothesis.

"If a huge majority of people from all over the planet say they feel the same way as the others from a medication .... That should be good enough."

The plural of anecdote isn't evidence. Science doesn't work that way.
