Right, but comparing opinions in the first place is odd. Is this concept more common than I'm giving credit for? I would assume that everyone thinks they have the best taste in music - if they like something better that would be their taste in music.
Yeah i think you're just missing something here. Its pretty common for people to compare themselves to others like this.
Not all of the questions are equally qualitative. Some are "i give more money to the homeless than average". You could theoretically measure this.
The purpose is probably just to understand peoples perceptions of themselves. (For example), i think i have better than average taste in music... after all, i meet artists and spend my free time going though new albums to find the next needle in a haystack.
