There is a difference between beating (taking out one’s frustration through violence) and spanking (imposing immediate consequences for bad behavior).
Imposing negative consequences for bad behavior is a way to guide the child to good behavior.
“My kids turned out great” is NOT a response, certainly not a rebuttal, of the research. It’s like saying, “Economists say that the minimum wage destroys jobs. But that’s bunk, because I have a job.”
The research shows that beating and spanking DO NOT differ in their effects. Both have negative effects, and neither has good effects.
