"The power of suggestion".
What Amir is saying is that all humans are flawed. Including him. Without doing a proper blind test anyone one can be fooled.into thinking they can hear a difference. Influences like price, appearance or even a suggestion from a trusted friend or source.
Once a person is convinced they hear a difference they put up a defensive wall. Especially after they spent a lot of money on a cable. No one wants to be made a fool of.
Measurements taken are not enough proof for them. Certainly there is something lacking in the data because they use their ears to hear the difference.The thing they fear the most is a blind test.
I stopped doing blind taste tests for wine. People got downright angry when they picked the cheap wine over their expensive one. They accused me of altering the labels to make them look foolish. They were absolutely positive they were right in their thinking and would not accept the facts proven to them. Humans.
