    Re: Child discipline was not measured

    Dr diPierro,

    Thank you for your feedback. Our conclusions do not refer to discipline practices at home, in schools and elsewhere. This is an ecological analysis of the link between bans and youth fighting based on country differences. There are of course limitations in this sort of design and these are discussed in the article.

    We conclude that societies that have less physical violence are safer places to grow up in because they are less violent.

    Dr. Elgar,

    I don’t have an issue with your hypothesis but your conclusion is not completely correct.

    You state:

    "Conclusions Country prohibition of corporal punishment is associated with less youth violence. Whether bans precipitated changes in child discipline or reflected a social milieu that inhibits youth violence remains unclear due to the study design and data limitations. However, these results support the hypothesis that societies that prohibit the use of corporal punishment are less violent for youth to grow up in than societies that have not.”

    I don’t see that you measured or hypothesized any changes in child discipline. You measured changes in child violence. This is a very important distinction.
