Pfh, when you have a large amount of data avaible on a subject, that is the statistics and science to help to,prove it. Phycology is similar, we can’t measure human thoughts and feelings, but we can gather data and with enough data we can indeed prove something. We don’t yet have the ability to know whether doses of vaccines will have negative effects, without trials. Someday we might have the ability to crunch the proper data with computers and get those answers without all the effort to gather the results in other ways. There is a not insignificant number of people who can hear differences, enough that there is a thriving industry that caters to them. Where’s the measurements that show I will like a particular amp vs another, or that there is even a difference between amps, or any audio equipment, that measures very similar. No such thing exists, yet we all readily acknowledge that we can hear differences. Products that on paper may look similar, can sound very different. And there is no way to measure what I will find sounds good, vs what you will.
