With the resurrection of this thread, I have yet another psychological explanation. The entire debate is moot. Strong objective and subjective viewpoints recreate very old theories that have failed. Lots of research points toward moderate, multi-factor, and complex explanations for human experience.
Consider the illustration below, as humans use abstract layered frameworks to understand everything. They rely heavily on their senses in their unique forms, to include: spatial relationships (i.e., vision or visual diagrams), linear/memory for sequences (i.e., reading or audio), touch (i.e., heat, cold, texture, pain), smell, etc.
Everyone seeks functional and interpretive value from their experiences, but humans – living meat with the ability to learn and reproduce – aren’t very consistent or good at learning or interpreting or organizing their experiences.
Subjective audiophiles generally focus on the middle of the pyramid: cognitive and environmental experiences. They KNOW what they see, what the hear, and what they like from direct personal experience. When coupled with lack of trust in others, a do-it-yourself attitude, etc. they don’t want or need any more information/data.
Not coincidentally, introspection was the first major method in university research psychology (circa 1900), and it proved to be TERRIBLE from a scientific viewpoint. Each person was different, there were no common measurements, and it led to endless confusion (which continues unabated with the subjective audio culture).
Introspective research led to a sharp backlash and the rise of behaviorism, which is a kind of measurements-only objectivism. However, by the 1960s strict behaviorism proved to be simplistic and also fell flat on its face, to be replaced by more moderate cognitive models that incorporate both objective data and subjective personal experiences (i.e., your body and your senses).
The anger of the objective/subjective debate follows from emotion and enjoyment getting mixed up with good and bad efforts to improve reproduction, improve quality, and understand what works and what doesn’t work. What makes me happy makes me happy. What makes you happy makes you happy. No arguing can change any of that. But, scientific bio- and psycho- acoustic research can predict what will be liked with decent accuracy.
