Again, you bring in the straw men. Is that a reflex action for you?
I see your quote marks. Where did I write that? Or is it another straw man?
Our uncontrolled experience routinely tells us that cables sound dramatically different, DACs sound dramatically different, Ethernet supply lines sound dramatically different, power cords sound dramatically different, well-measuring amps sound dramatically different, speaker A sounds significantly superior than B sighted then the opposite under controlled conditions. And like you said, Olive says we are so suggestible that you only have to tell us that a live performer is performing, and we will live that experience. Ergo, we only have to think that a live performance is happening, and we will live that experience. Ergo, we only have to think that a mere reproduction is happening, and we will live that experience.
The more we learn about perception, we more we realise that context re-writes raw data, but our hard-wiring says it’s still raw data. It’s a natural-selection survival mechanism: believe what our senses are telling us, or die. But in truth our perceptions are creations, not observations. As you say, we sensibly assume it is real for practical purposes. But that’s different from saying we are sure it would survive a test. “They could never be mistaken as being electronic samples.” - and that’s not a mis-quote. Yet you quoted Olive saying you only have to fib and it happens.
So, indeed, how far does it make sense to NOT take that scepticism? You stopped at a random point of your own making. I say test it. You say nah, I don’t need to, it’s real and sure and true as can be. I say hmmmm.
Why restrict it to “average person”? Let’s open the field up a little. Toole, 2008, p.14: “Live vs reproduced comparison demonstrations were also conducted by RCA in 1947 (using a full symphony orchestra [Olson, 1957, p.606]), Wharfedale in the 1950s (Briggs, 1958, p.302), Acoustic Research in the 1960s, and probably others. All were successful in persuading audiences that near perfection in sound reproduction had arrived.”
OK, “near perfection” is not perfection. But clearly, better than your “could never be mistaken” certainty. And that was 50, 60, 75 years ago.
In case your next straw-man question is, “So you are saying my hifi recordings are actually indistinguishable from live, and I am only imagining that they aren’t????” No. Toole also goes on to say, (op cit)., “the bulk of recordings quickly drifted into areas of more artistic interpretation.”, and lays the foremost blame with recording. They aren’t putting the microphones in positions where playback could have a chance to mimic live.

I think we are talking past one another.
You seem to be saying that I have no basis on which to think I can examine the character of a sound, no basis on which to have any confidence I've noted anything accurately, without it being under blind testing conditions. On the basis that...hey...biases and all that. I'm pointing out that is an overreach of the skeptical mindset.
You seem to be talking about
scientific certainty.
I'm talking about
practicality.
Both are reasonable.
If you want scientific certainty about ANYTHING in our experience then you do the rigorous science.
But I have gone to pains to try and be clear I'm talking about practicality and what is actually feasible for the average person and on that basis what conclusions from experience, even if tentative, are reasonable.
I'm pretty sure my perception is such that I can reliably identify my mother's voice on the phone (or in person) from my brother's voice. Have I run the blind tests? No. That would be impractical. But it has seemed quite reliable and it shouldn't be controversial that one could remember and distinguish the different characteristics of voices we know.
Likewise, I work with sound all day long - recording, manipulating it, eqs, effects, etc. This entails constantly identifying the specific character of different sounds and making the right decisions on how to change that character. None of it is done by measuring or blind testing. I hear wind rumble, I know which eq setting will get rid of it. I hear too much sibilance, I can reliably eq it out. Something sounds thin without impact, I know what to add that will bring that impact. If I'm recording and I percieve wind rumble or sibilance or many other issues, I take steps to alter this and successfully solve the problem. All this in the absence of blind testing to scientifically ensure I'm right about every single such inference.
If I were not reliably identifying the sonic qualities of sounds all day long, and their changes, my job would literally be impossible.
If someone suggested that I need to double blind test every sonic inference I make, I hope you understand how that is both impractical, and also absurd given I produce reliable results for achieving my goals and for my clients without blind testing.
Do you see now what I'm getting at? Yes, there is *always* the specter and possibility of bias and misinterpretation in everything we do. But that does not entail of course that any particular instance is actually in error, or that we need to employ scientific rigor to in order to have some reasonable level of confidence in what we perceive.
If I'm positioning speakers I can hear bass nodes, thumpiness and other characteristics change as I move them around. Is a microphone and computer room correction system more specific, detailed and reliable? Sure. But I can detect changes accurately enough to effect changes and get it to where I want sonically.
If we were listening to a bose radio and a giant pair of Magico speakers in the same room, can we not talk about the sonic differences we hear?
Or do we need to shut down any such subjective impressions in lieu of not being able to double blind test? Does that sound practical?
Is it that implausible that we would actually be perceiving real differences between huge Magico speakers and a bose radio? How far to you take skepticism in practical terms?
This is what I'm talking about. And why, on that level, it seems silly to say I couldn't close my eyes, listen to a live instrument, and come away with any reasonable perception or inferences about the character of the sound. Nor that I couldn't do the same with a sound system. And have no basis to draw some plausible comparison, even if not scientifically rigorous. To say for instance that one has no basis for any confidence he has percieved a real difference between standing in front of a live drumset being played, and hearing drums played back on small Spendor bookshelf monitors, is getting silly. Yes, if looking for scientific rigor, you do the double blind science.
But in practical terms, there is plenty of reason to have enough confidence in our perceptual inferences where distinct sonic differences are plausible.
Now at this point you may wish to say "but this site is devoted to science, so scientific results are all we should be talking about." But in practice, that's not how things play out. We do exchange impressions of how things sound. It always comes with the caveat when it's not via double blind testing or whatever, just as my observations were presented as not being scientific. But in practice we can talk about plausible differences we hear in gear, what live sounds like to us, etc.
