Want your kid to stop whatever dangerous/annoying/forbidden behavior he’s doing right now? Spanking will probably work — for now.

But be prepared for that same child to be more aggressive toward you and his siblings, his friends and his eventual spouse. Oh, and get ready for some other antisocial behaviors too.

A new analysis of two decades of research on the long-term effects of physical punishment in children concludes that spanking doesn’t work and can actually wreak havoc on kids’ long-term development

Children who are spanked may feel depressed and devalued, and their sense of self-worth can suffer. Harsh punishments can wind up backfiring because they can foster lying in children who are desperate to avoid being spanked. Later in life, physical punishment is linked to mental health problems including depression, anxiety and drug and alcohol use. There’s neuroimaging evidence that physical punishment may alter parts of the brain involved in performance on IQ tests and up the likelihood of substance abuse. And there’s also early data that spanking could affect areas of the brain involved in emotion and stress regulation.
