"Det låter intressant. Kan du ge några exempel? "
Hörbara skillnader mellan en massa kablar, magiska stenar, tejpbitar i gardinerna, förstärkare och CD-spelare. Listan kan göras lång. Det finns skillnader rapporterade, men den stora massan skillnader har inte kunnat påvisats när lyssningarna gjorts blint.

Annars finns hela forskarkåren som, där experimentet kräver det, utformar dubbelblinda tester. Fråga vilken läkemedelsforskare som helst.
Dessutom, nu vänder du på steken igen. Först kräver du att "en kabeltroende" ska vara med att skifta prylarna i ett blindtest för att validera metoden, sen säger du att den personen inte behövs. Hur ska du ha det?
För det tredje, om personen har köpt en kabel för 25000 och är nöjd med det, vad ska jag göra åt det? Jag har aldrig sagt att han ska byta om han är nöjd. Var har du läst det? Du behöver inte bevisa nåt för mig. Du läser tydligen inte riktigt på vad jag skriver. Debatten finns för att det finns annat att lägga pengar på, om man vill det.
Du ville heller inte svara på frågorna. Varför vill du använda oss för att testa om blindtestet fungerar? Hur skulle du validera metoden?

Det finns som jag postat tidigare en mängd tester i Stereophile och andra tidskrifter. Jag citerar Tom Nouisane från rec.audio.high-end:
Citat:
With regard to amplifiers as of May 1990 there had been such tests. In 1978 QUAD published an erxperiment with 576 trials. In 1980 Smith peterson and Jackson published an experiment with 1104 trials; in 1989 Stereophile published a 3530 trial comparison. In 1986 Clark & Masters published an experiment with 772 trials. All were null.
There's a misconception that blind tests tend to have very small sample sizes. As of 1990 the 23 published amplifier experiments had a mean average of 426 and a median of 90 trials. If we exclude the 3530 trial experiment the mean becomes 285 trials. The median remains unchanged.
