You might recall a survey here, which seems to establish a connection between hemisphere dominance and whether one is likely to readily perceive sonic differences in cables. To emphasise this is NOT the same as being left/right handed, it concerns behavioural influences in classic psychology. The survey is here :viewtopic.php?t=27412
At the time of posting, zero from 6 right brained respondents readily perceive such things, versus 6 from 18 left brainers. Now, I'm not saying that is a vigorous test or anything beyond a bit of fun. But it was a surprising result.
It does suggest there is a set of behavioural questions which can be used as a predictor for whether one might readily perceive such things. What it doesn't address is whether the behaviour traits are causal, or whether there is some internal common brain function association.
But, right or left brained doesn't help anyone pass blind A/B tests. Which history suggests always fail in such things. And to me that strongly implies the cause is behavioural, rather than possession of an 'extra sense'.
