sciencedaily.com – A study shows that in countries where there is a complete ban on all corporal punishment of children there is less fighting among young people. There was 31 percent less physical fighting in young men and 42 percent less physical fighting in young women in countries where corporal punishment was banned in all settings, compared with those where corporal punishment was permitted both at school and at home. In countries where there was a partial ban on corporal punishment (such as in Canada,...
