Why is it too far fetched?
You make a claim saying there is only one conclusion, I give an alternate conclusion you say is to far fetched. I fail to see how humans have bias is more far fetched than unknown signals hidden in wire unknown to science?? Let's not assume bias is to far fetched since we know it's a common human condition. You make an extraordinary claim concerning hidden signals, do you have any extraordinary evidence?
The problem is that we both can't prove our point using standard tests. They don't take too much into account, I wrote about it in my last answer to you.
Besides, my question was about something else. If, after all, we agree that there are people who distinguish the sound of one wire from another, what exactly can they hear or feel?
ps - this is from Essien's article:
"Many observers wonder at the listeners' ability to extract recognizable temporal and intonational patterns from the seemingly chaotic acoustic signal... “Richly structured perception on the one hand vs various imperfections in production including a wide range of deviations from target norms as well as large scale intra and inter individual variation on the other.” For Wode, it is a paradox; for Bloothooft (1995) it is a mystery"
