From an old, old post...
People like to help each other, and do not like it when their help is questioned. Beliefs enter into it, people get riled, conversation degenerates.
Example:
A: I just added a new Pet Rock to my system, the imaging is better, a veil was lifted, bass is better, you have to get one of these!
B. I do not see how a pet rock can do any of that. Have you measured the system?
A: Why would I care about measurements? I can hear it!
B. There's no way a pet rock can do that. Without measurements, you have no proof.
A: What do you mean "no proof"? Didn't I just say I can hear a difference?
B: That is not proof. You need to run a controlled test, have somebody place and remove the pet rock several times and see if you can tell when it is there.
A: I don't need some test, I can tell it works! And I just had my friend over and he heard it too so there!
B: That's ridiculous you are both nuts. I'm just trying to save you money.
A: OK, I found an article by the Pet Rock Sound chief engineer. I don't understand it, but he says it aligns the molecular flow of the universe inside my room and that's why it works.
B: Sounds like marketing. What measurements did they take?
A: There's a graph, it shows ripples in the force without the Pet Rock that are gone when it is added. Happy now?
B: No, that is meaningless. You are all mad.
A: Well, prove it! Measure the molecular flow with and without a Pet Rock and see the difference! Then you can see and show us all why it works.
B: That is nuts and I don't have anything like that kind of equipment.
A: Then you can't prove it doesn't work! You're a geek with no ears!
B: You have so much expectation bias it is running out of your ears. No wonder you think you hear something.
A; Snooty objectivist scumbag.
B: Ignorant gullible subjectivist.
