Despite also listening to a form of anger - albeit laced with humor this time - these students performed better on the creative problems. The study also showed that students exposed to sarcasm performed better on problems that required more “cognitive complexity,” or the ability to look at issues from more than one angle, than those that didn’t hear such comments. The researchers suggest that while the underlying anger helped to focus the students, the inherent humor of sarcasm helped to offset the damage that anger can do.

It’s Time To Let Kids Be Adults

Because beauty pageants don’t just provide gainful employment for children, they also provide invaluable life lessons. What better education can a child get than that supplied before the sparkly curtain? How better can we prepare our offspring for the future than by letting them “learn by doing” the secrets of a whiter-than-white smile, a sassy shimmy and some knee-high boots? What we are looking to do is create the good citizens of tomorrow, and when I look at the world of kiddie pageants, I can conceive of no better breeding ground for those citizens.
