Are many audiophiles only seeking approval of the next purchase?

Words are flowing out like endless rain into a paper cup,
They slither while they pass, they slip away across the universe
Pools of sorrow, waves of joy are drifting through my open mind,
Possessing and caressing me.

Confirmation bias is a phenomenon wherein decision makers have been shown to actively seek out and assign more weight to evidence that confirms their hypothesis, and ignore or underweigh evidence that could disconfirm their hypothesis.

I buy with expert insight into my purchase don't need anybody's ok but mine.

Another way to say that...  folks tend to stick with what they like, instead of constantly doubting themselves. LOL  
In scientific studies it might be a problem. It real life it keeps you from going insane.

Well, we have to at least visit and hang out with insane, otherwise we’ll never know the difference.

Knew an old professor who kept his sanity card in his wallet.

He was discharged from the psyche ward many decades back, after a short visit.

He was declared legally sane.

He would show it to people who were acting crazy.

He was legally sane..but how about them? Hmmm?

That such zany fun can be had in this world...
