Almost every single day you hear and read terrifying news about violence. A football team kicks the arbiter to death (Mohamed, 2013), two teenagers beat up a 14-year-old boy (Lai, 2012), and a 17-year-old boy is stabbed to death (Mercer, 2013), to name just a few. With all this media attention on violence, it’s not strange that most people believe our world today is more dangerous than ever. Indeed, most people believe violence has increased the past decades. However, believe it or not, research shows there is actually a decline in violence.
