I guess I _never_ failed a blind test, but that's
not important. Most
people are comfortable with MP3s, but if I talk to them and point them
to the lossy parts, they're able to notice the loss too, they are
usually not annoyed by the loss.
Tests with uneducated people are useless, those tests just should ensure
how far the industry could go.
This is just your personal and *uneducated* (ie. wrong) opinion.
ABX tests are double blind statistics tests, double blind tests are
widely, massively used in medical statistics to test drug treatments
against a disease (eg. tumor).
The goal is to ensure that treatment A is better than B, and "blind"
stand for "the patient is not aware of the treatment he receives so
variability is not conditioned from psychology" and morover the doctor
is not aware of what the patient was given (the drug or a placebo).
What you call "uneducated" is the assupmtion which the test relies on.
Don't spread misconception.
