Crutchfield's Speaker Compare

Ah, expectation bias!

@ tom8473. We all have different ears, so maybe yours could not detect differences in sound among speakers. As discussed above, the tool is best for relative comparisons among speakers. 

@ thecarpathian. Can you elaborate on expectation bias? 

Hi, luciano33.

When one has a preconceived notion in one's mind about the outcome of something before doing it, they have already made up their mind as to the outcome, and that is what is most likely to occur. As Tom had suspected in advance what he was going to hear, that is what he heard.
That is a decent description of expectation bias, even though I was half kidding and really have no idea why as to he not hearing a difference...

I was half kidding as well. That's sort of how the mind works. I am a scientist and we actually have to train our minds into not being bias and let the results speak for themselves. Why are we by default biased? I am not sure...it's not my field. I have to confess that before actually listening to different speakers through this tool I thought their sound was going to be way off...and what I experienced was completely different. It actually surprised me. I guess I had a null hypothesis in my mind and tested it without being fully conscious about it? :D
I am with you, I can't understand those saying they can't hear sound differences among speakers because they were very obvious to me. Cheers!
