As I’ve become more acutely aware of the evils of expectation bias I wonder if I am now suffering from something I’d call reverse expectation bias.
In my definition this is the expectation that there should be no difference in sound (even if one might exist) leading to not hearing / observing any change in sound quality.
I’m half serious / half joking here! I no longer trust my ears
Short answer: Yes. In medicine it's called the nocebo effect, basically the "bad" version of the placebo effect.
I once read a review on a homeopathic remedy, i.e. sugar pill, i.e. actually does nothing. The medical equivalent of swapping one 3-foot cable for another. The reviewer said it gave them a terrible allergic reaction and they would never take this "remedy" again. The poor thing gave themselves a bad case of 'reverse expectation bias', aka nocebo effect.
In my mind, it's a certainty that the same thing can and does happen in audio.
