i get in arguments with my INTJ friend all the time, but on the other hand its fun to own him
. for example last time we argued about analog vs digital distortion pedal on guitar. he didnt understand that there can be any difference, because digital can be programmed to do what ever you want to the sound, and refused to understand that digital pedals doesent work the same way as if you would process the signal on a computer manually, because the digital pedal can be programmed to do what ever you want.. i explained in every possible way to him that there is a difference in them and why they sound different. he ofc went to look wikipedia about audio signal processing, and found out that analog signal is more lossy and gets more noise than digital, (what he refused to understand that good analog pedal on guitar doesent have this noise or loss of sound and that its just theoretical and doesent apply to this) so he started saying that digital distortion pedal is superior to analog in every aspect.
after about 2 hours i managed him to understand that they actually sound different due to different cut off or high/low frequencies. but i made a mistake of saying that analog sounds more pleasing to ear due to different type of processing of the sound and he thinks its just an opinion because some people prefer digital distortion. i didnt want to waste the next week explaining to him why brains reacts differently to this kind of difference of cutting of frequencies..
funny thing with this was that my INTJ friend looked for factual information of signal processing so much and only concentrated on facts said by professionals, that he didnt realize that what he was looking was irrelevant to the topic, and refused to believe when i said it, because the facts that he was looking at was on his favor of the argument(or so it looked to him).
