I think there's a subtle line between positive reinforcement and idol worship. It's always helpful to get positive reinforcement in pretty much any situation. Though I've seen kids who have turned out terribly because they have never been told when they've done something wrong or even remotely socially unacceptable.

I mean, maybe these people will turn out to be geniuses thanks to the fact that nobody has ever told them to do anything differently, or maybe they'll get a really harsh reality check from somebody who has had even more "positive reinforcement" than them. These things always work in gradations. In any case, it's pretty funny to watch.
