scientific double blinded cable test

An old philosopher once said, never go test something at someone else’s system. You might not like what you hear. 😬 There are too many variables.

When a group of people all hear the same thing, at the same time, in the same setting, and under the same circumstances, double blind testing would be entirely redundant....  Double blind testing would only serve to dumb down an event which is in it's very nature....

It's okay if we agree to disagree. All good :)

To my way of thinking, the fact that the group all heard the same thing is precisely the reason for the blind test; to do away with "bias". The blind test would serve as confirmation or further evidence. It doesn't dumb it down, it smartens it up.

So given your position on the matter, under what scenario should a blind test be used?

I say it was blind. Looks like we disagree. Oh well....
