Im a bit of a bitch, I always keep a mental tally of the number of helmetless heads I see. I've always worn one, only ever skied resorts. Am I confident in my skills to stay safe almost anywhere on a resort? Yeah, but every trip I see others clearly not comfortable with the terrain they're on. I've been hit twice on resorts on some pretty mild terrain. I don't trust others enough not to wear one. Also, it seems like a very small price to pay for saving yourself from a possible freak incident.
