Over several years we have been experiencing school shootings that are mainly acted out by young men and consistently around the age of 15 years. Why is it so common to see this age pop up for the shootings? Sometimes we see the young man at 14. Other times we see the young man’s age at 16. It is usually right in this window of 14-16. What can we understand about this critical age that is completely unknown to psychologists and others who try to study this phenomena?
