I am not against blind ABX testing- when done properly. A single person doing an ABX blind test might give them comfort and security that they are making the right choice but those results are meaningless to me. It still comes down to that person's personal preference. So why look down on me or thumb your nose at me because I do not want to take the time and trouble to do my own personal blind ABX test? From my viewpoint if a person cannot trust themselves to make a decision that they will be happy with, then don't do it.
A real blind ABX test would be conducted by a panel of jurists and would be repeatable with a different panel of jurists on a different day and different locations.
All the YouTuber did was validate his own preference with his own ABX blind test. He didn't even mention his preference because it would be meaningless to us. I also got a chuckle when he said that Danny guessed right 8 out of 10 times but he guess right 18 out of 20 times with his own test. So he guessed right one more time than Danny but somehow Danny's results are insignificant while his results are valid. Funny math.
