I don't think that the social norms posters accomplish anything. Personally, whenever i'm walking down the hallway i just make fun of them. I don't think that students will look at them and be inspired not to smoke ciggarets or drink alcohol. They say 82% don't smoke ciggarets, but that means that around 540 students do, and i'm sure more than half of those people aren't even old enough to smoke. I agree that probably most of the students that take the survey don't even take it seriously, and just think its a waste of time.
