yeah I guess that would be a better.
I think it's also to do with the "type" of person you are that affects what music you like (in a very harsh generalization) so hooligan types might like dance, generic full-On or what ever... So I think its more in the aspects of social connections that peoples actual tastes (still in general of course) are affected.
So do intelligence affect "what kind of person" you are or who your friends are? That's a whole different discussion!
Because I sort of have the same experiences with people as buzzman talks about, certainly here in Denmark.... but its actually not so much if "real psy-trance" attracts intelligent people or not, but more if stupid people like stupid music not really sure that's true, or if a truly stupid music genre exists?!
