Collective animals

I went to the Design Act exhibition/festival yesterday in Moscow. It was interesting, although they didn't have as many things there as I have expected - I remember saying things like "That's an interesting/clever idea" fairly often, however not so much at the actual exhibition but more at the Design Market . In one of the articles about the exibition, it read: "I's usually not one person that invents something new, rather several people invent a similar thing all over the world at around the same time. There must be some sort of Collective Consciousness where ideas grow and mature". Wikipedia defines it as:
"Collective consciousness refers to the shared beliefs and moral attitudes which operate as a unifying force within society." - Not quite the same thing the article meant.

Well that got me thinking just how often I experienced that Collective Consiousness - no, Im not trying to say Im a great inventor, its much simpler than that. Whenever I start liking something, not long after I do, everyone suddenly seem to be into the same sort of thing, even people that I've never had any contact with (say, people whos blogs I read but never comment).
Even simply when I find a band a like (Florence and the Machine, for example) and within months they get Brit Awards and I hear them on the radio in Russia!
Or:
I get sick of shimmery eyeshadow and wish there was more matts on the market. Before I know it, Revelon and Pupa have a new "matt perfection collection"... It's weird.
Sometimes I think that, possibly I just get brainwashed unconsiously and in reality all those things were popular before I found out about them/started liking them.

Or maybe Im a very good entrepreneur?
