What little info I know of, says people opposing an idea become hardened against the opposite viewpoint the more information they are provided with.
That goes for both religious people, and what otherwise seem to be rational objective people. Normal human reaction in some sense. Difficult thing to overcome.
Then you have complicated reality. Our highly esteemed, and rightly so member on things audio and hearing J_J once told me something couldn't be happening, and I have 100% certainty it was. I didn't make me stop listening to J_J. He was a big influence helping me get my head out of my own rear end on audio matters. This was way back in the usenet days.
Condensing details, my CD player starting skipping oddly. It would play 4 seconds, skip backwards 3 second and keep on in that manner. A real head scratcher. I eventually determined a damaged outdoor sodium light was emitting some sort of noise causing this. There was no doubt. I could disconnect the light and CD player was perfect. Plug it in and CD player did this odd 4 steps forward 3 steps back skipping. I did it both ways several times. And a pre-eminent expert told me it wouldn't be so.
Now that is the value of empirical experiment. One doesn't get a pass on argument from authority (not that J_J himself was doing this only others agreeing with him). He was WRONG. (nor do I think J_J claims perfection). There was also one other incident he described as not happening though it too in fact was happening.
J_J once told me he could tell me how things worked as far as known, but if I wanted to take part in useful discussion he wasn't doing the homework for me. I had to get up to speed. Instead of being pissed, I asked him for guidance on getting up to speed. I'm thinking he doubted it would do any good. He gave me a couple of texts on hearing to start with. I purchased them, and studied them and learned a great deal. Since then I have thought all audio reviewers should be required to study such things if they wish to be taken seriously.
So I am not sure how you get people to change sides or change methodology. Just doubling down on facts rarely works. I have read from several sources someone can only benefit from a guide when they are ready for one. It certainly would help if the overly subjective audio press didn't start with the premise that objective facts mean nothing in audio. Combined with the increasing distrust of experts you have a real uphill battle.
So I owe
@j_j a thanks and have gratitude he steered me the right way. The more I learned the more things make sense. Yet twice I could have put in my list the two times this esteemed expert was definitely wrong, and used it to bolster the idea his opinions were wrong-headed and beside the point.
