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. /r -- L'unica speranza di catarsi, ammesso che ne esista una, resta affidata all'istinto di ribellione, alla rivolta non isterilita in progetti, alla protesta violenta e viscerale.
