Hm. I'm a fan of reverse psychology, perhaps BECAUSE of early experiences with nagging(which, as one wag put it, is "the repetition of unpalatable truths"). For example, encouraging a child to "go ahead, stick your finger in that light socket", or, "don't just smoke one cigarette, I've heard that five or six at one time is better" are samples of behavior modification I've heard used, which smart kids caught on to as being just a tad too enthusiastic or found out the hard way that following the herd might not be a sensible path, after all.
