Are many audiophiles only seeking approval of the next purchase?

When I visit audiophile friends many have just made a purchase. They will ask me what I think after a brief listen. What can you say but thats great good buy to say otherwise is hurtful. In forums many are seeking consensus since they want to do something and are seeking agreement that its OK to do so. Consensus is how you get lite beer to be the best selling and most consumed. All of humanity is not at the same level of experance or education. If I seek consensus the inexperance or highly biased has as much sway as the expert. 

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.
