Oh man, given I have again been challenging some subjectivist tropes on "another forum" that video hits too close to home.
The irony never ceases to amaze me:
Skeptic: You may be hearing some change in the sound of the new fuse/AC cable (whatever) but it's a technically suspect claim and since we can all be fooled by our biases, it would be good to at least have some measurements suggesting something objective is happening, and/or try listening tests in way that tries to reduce the influence of those biases - blind testing.
Subjectivist Audiophile: Nonsense! The only way to determine these things is by listening!
Skeptic: Well, as I said, I'm not completely ruling out your findings, but we can all be misled by sighted bias. So, yes, let's listen, but it's good to reduce the influence of sighted knowledge in the tests.
Subjectivist Audiophile: Science hasn't discovered everything you know!
Skeptic: No, of course not. But that isn't a reason to believe everything that's claimed, or everything we think we hear.
Subjectivist Audiophile: Look, you weren't there! You can't tell me what I hear or not. The only way to decide is for me to listen, and my ears aren't wrong!"
Skeptic: But we know our subjective impressions are prone to error, so it makes sense to look at ways of reducing the influence of those errors.
I know I'm certainly fallible and I have had some eye-opening experience blind testing equipment I thought sounded obviously different. I'm just saying that personally I'm not convinced of the phenomenon under discussion, but I'm certainly open to good evidence. It's just that pure anecdote isn't a terribly reliable form of evidence, especially in regards to controversial claims.
Subjectivist Audiophile: You people are such DOGMATISTS! Why won't you just accept that I HEAR WHAT I HEAR, I CAN'T BE WRONG, and THAT'S THAT!
