Either my qualia are objectively different from everyone else's, or it's 90% marketing fluff and psychological tribalism.
It's not so much that there can't be a difference between the various cokes, Pepsis, and other brands--I just find it hard to believe that the difference is so great that people can find one repulsive and the other divine.
It's all just sweet, fizzy drink. Side by side I might be able to tell coke and new coke apart. I don't find it difficult to believe that people have a preference. I find it difficult to believe that one could be so swayed by the difference to revolt.
So I cannot shake that it's more tribal identity than taste... Sort of like rock vs hip-hop.
Yea, I know telling people it's mostly mental is going to be controversial, so sorry.
