Teaching and learning from preschoolers.
I've had people shrug at my moral stance and insist that spanking "works," and I'm sure it does. There are lots of things that work that I will never try. If I disagree with you, shouting you down works, but wouldn't it be better if I engaged you in reasonable debate? If I need money, stealing works, but wouldn't it better if I worked to earn a higher income? If you're standing in my way, pushing you works, but wouldn't it be better to politely ask you to allow me to pass? Indeed, spanking may work, but there are better ways. They just take more effort.
"Research shows that spanking corrects misbehavior. But it also shows that spanking does not work better than other modes of correction, such as time out, explaining, and depriving a child of privileges. Moreover, the research clearly shows that the gains from spanking come at a big cost. These include weakening the tie between children and parents and increasing the probability that the child will hit other children and their parents, and as adults, hit a dating or marital partner. Spanking also slows down mental development and lowers the probability of a child doing well in school . . . More than 100 studies have detailed these side effects of spanking, with more than 90 percent agreement among them. There is probably no other aspect of parenting and child behavior where the results are so consistent."
