one group perpetuates the stigma to another group. people often *think* that no one goes out to X/Y party til 11-12, so then they themselves make it a point not to show up til late. it's all about that mindstate, because these people, in reality, are just sitting around waiting to go out and/or pregaming. nothing is actually stopping them other than the mindset that no one else is going to be there. if we could simultaneously abolish this mindset, everyone would go earlier (10, maybe even 9).
solution to the problem? put dope headliners on early. :)
