Whichever side is missing. If I'm surrounded by people bashing something, I'll more easily see something of worth in the object. If something is widely loved, my attraction cools or becomes more analytical and questioning - if I can figure out why people like something, and it makes sense, I may yet give it a try. The first mechanism, sniffing out a value in and use for things that are supposed to be inferior, is stronger, more automatic and compelling.
In theory, if others are seeing one side, and I pick up the other side, maybe we can put the sides together for a more emotionally balanced and realistic image. But it also comes from a core wound - I'm defending against the notion that a thing can exist that has no place in the universe. I'll make a place if I have to - for an object and, down deep, for myself.
