22+ years of experience in the field of computer networking is informing that you have absolutely no idea what you are talking about. Show one example of where noise enters the any device in a residential setting via a 10ft ethernet cable, or just fade away.
But before you fade away, since you called me naive, maybe you want to do research on how the brain works. There is a whole field of psychology that focuses on this. Here's the definition of confirmation bias: "Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one's prior beliefs or values"
