one simply can't seem to be able to thrive on doubt. I feel like being right has nothing to do with happiness, it's thinking we are right that matters, so that we can remove those annoying doubts that put shadows on our everyday happiness. "no diggity, no doubt".
statistical results from DBT and ABX are used to decide if a drug is killing or helping people? well sure statistics are good enough for unimportant life and death questions, but they're not enough for amateur music listener. why? because they didn't say I was right last time.
physical measurements are good enough when it comes to build a plane, send a ship into space, or built a 50stories building with 90% sand. but they can't explain sound pressure on a tympanic membrane. why? because measurements said that my favorite headphone had distortions. I can't live with that, better reject science entirely.
-some rely on logic and the idea that an engineer might know a little more about electrical signal than some dude listening to music. those also tend to believe that humans are mostly made the same, that one day they will need glasses and that if doctors say human hearing goes from 20hz to 20khz then chances are that their own hearing abilities also lingers somewhere inside those values.
those guys often lose some happiness in exchange for truth as they learn they are not always right.
-others rely on ego and fame, always thinking that their own opinion or the opinion of the guy they respect most is the truth, and that they can perfectly be right while the entire world is wrong. those guys are the happiest as they never doubt. of course unless they're the american hero of a SF movie, in real life they pretty much always end up being dead wrong. but who cares about details like being wrong? they sure don't. ^_^
