A couple real life anecdotes I've collected over the years about how our senses deceive us:
1. The Anheiser Busch experimental brewery was working on a Christmas beer, a new recipe utilizing cinnamon and nutmeg. The brewers at the experimental brewery emailed their supervisor at the main production brewery saying that they couldn't seem to get enough cinnamon flavor. They exchanged emails, going over the chemistry of cinnamon in beer, cinnamon's oxidizing process over time, etc. Finally the boss said "FedEx me a sample bottle." When he opened the sample he was overwhelmed by the aroma and flavor of what seemed like carbonated liquid cinnamon. Thinking that his experimental brewers had gone off the rails, he booked a flight. When he arrived at the experimental brewery the next day -even before he got into the building- he had solved the problem. The brewery reeked of cinnamon, the brewer's clothes smelled like cinnamon, even the parking lot smelled like cinnamon. The experimental brewers ad been working with cinnamon so much, that they had become desensitized to it and so kept adding and adding cinnamon , compounding the problem.
2. Both the patients and the doctors in double blinded drug trials are ignorant of whether the pills dispensed are real medicine or a placebo (hence double blinded). Patients of similar demographics and disease are divided into three groups, one given placebo, one given real medicine, and another not given a pill at all. It is very common for the cholesterol levels in both the medicine group and the placebo group to improve , while the cholesterol levels in the third (no pill at all) group get worse. The power of suggestion literally changes peoples blood composition. If suggestion is that powerful, it definitely can influence us to believe we hear more detail or "richness" or "color" in a favored audio brand or technology.
3. I took an undergrad psych class where partway through a lecture a person walked in though the front door, apologized to the class for interrupting and spoke with the professor at the lectern for several minutes while the class waited. The gentleman left, and the professor continued his lecture. Some time after resuming the professor stopped his lecture and asked the class to describe the man. Turns out it was planned and the interrupter was one of his grad students. So....what did he look like? What color was his hair, long or short? Beard or no? Race? T shirt or button down? What color? The classroom was small (30ish seats) and he was in front speaking to the professor for 5 full minutes yet our answers were all over the map. He was white...no...Hispanic.... blonde hair maybe...., beard...no, a goatee... red t shirt...maybe blue polo....much taller than the professor...no same height, and so on. The class couldn't agree on any detail of his appearance or what they discussed, and most got it entirely wrong.
So whenever anyone says something like "I trust my ears," or "I know what I hear/saw," or anything else similar, they are either willfully ignorant or they come by their ignorance honestly. Either way people who are so blind to their own natural humanity haaaaate being told they're wrong.
