@theaudiotweak, Very true Tom. But, you are in a strange environment and a very large mysterious one not in your own living room. You don't get scared when you turn the lights out in your bedroom. It is a more primitive instinct more likely to be manifest in children. My favorite instinct fighting situation is being in an MRI scanner. Even if you are not technically claustrophobic you get uncomfortable. We instinctively do not like being in tight places we can't easily get out of. I have many patients I have to tranquilize to get a scan done. I have one that will never have an MRI without being totally knocked out. Why do we all have these instincts? Simple we were better at staying alive and having children. The ones without this instinct were more likely to get killed prematurely. Many of these instinct got started long before Homo Sapiens was around. They were passed down to us. The survival instinct is a good example.
Now. what about the instinct to buy silly audio tweaks that do nothing but subsidize someone's income. It is obvious that this instinct does not occur in all humans. Since nowadays survival equals money goes across without this instinct will out survive the ones that have. So, over 1,000,000 years this instinct will extinguish. Looking back on it people will think that the tweak buyers are permanent. Just an extension of the idea:-)
