How do you know your ab results are more reliable than your abx results?
I have never compared the results of an AB test vs an ABX test doing the same test subjects, so I have never judged the reliability of the test protocols.
What I said was that I feel more relaxed doing a simple and straightforward AB listening test than doing an ABX test as I find the latter a bit distractive, and I believe that fewer distractions will lead to more reliable test results. But again, I have never done any comparison between AB and ABX test results of the same subjects, and I have always accepted the result no matter the test protocol.
And this is why I feel more distracted by an ABX test VS (for me) the more relaxed and more straightforward way of an AB test…
When doing an ABX test, I constantly have to remined myself that X is supposed to be either the same as A or the same as B, and that is enough for me to be distracted and more subject to “brain farts” on my part, it's like I have to think in the opposite direction of how my way of thinking normally works in normal everyday situations where I’m more used to the straightforward question;
“do I like this(A) more than that(B)?”
In an AB test, the only thing I don't know at the start of every test round is if it's starts with A or B, I simply just have to focus on which one is which and that works way better to me in a similar matter of;
“do I like this(A) more than that(B)?”
The above
“problem” may just be me and the way I’m thinking, but for me, the ABX test protocol makes me more distracted while the AB test protocol makes me more relaxed comparing the two test subjects in a more straightforward manner. It may be a “handicap” on my part, but so what, the AB protocol just happens to work better for me.
