I think drunk driving campaigns are a great success story. We don't see them pushing drunk driving to dramatic new lows each year because we're already close to the limit of what they can accomplish. There are people who drink and drive despite them, but there would be far more people drinking and driving without them.

If you're a pessimist, maybe my pessimism has experienced integer overflow into optimism.

I admit that the DD was not a good example for two reasons:

One, there are very aggressive negative consequences --this has an impact on some people.

Two, we have a better chance of changing behavior if we do it in a coordinated manner with good methods when we start young. So, I may be a bit too pessimistic since I think we can make a difference if we start young but with good persistence practices. Given we indoctrinate kids against this since middle school, I think it's made a difference.
