On April 10, 2018, Harris and Dylan entered Ceylon High School and began shooting teachers

and students. Thirteen individuals died, and the psychological community was again asked to

explain such violent behavior. A psychologist might decide to interview Ceylon students to

obtain their perspectives on the factors that motivated the two young men to commit such a

horrendous act. A group of ten students has already decided to meet and discuss the events of

that day. The psychologist asks if it would be all right to attend the meeting and ask them some

questions. The students agree, and the psychologist records their thoughts. Based on this

information, the psychologist concludes that a primary reason for the violent behavior was the

peer dynamics in the school that created groups of outcasts.
