When a researcher finds an interesting topic to study such as aggression, the goal is often to study it in a way that is as true to life as possible. However, researchers must act in an ethical manner.  To do this, they must balance their research goals with the best interests of the participants. Ethics often enter into the planning process when researchers identify all of the ways they can manipulate or measure a variable, but then make their final decision based on how they should manipulate or measure a variable. After receiving a poor grade on a test or paper, a college student may appear to take it out on (i.e., act in an aggressive manner toward) their roommates by being mean or nasty, screaming, throwing things, or even becoming physically violent. Aggression is an important human behavior to study and understand due to the implications it has for interpersonal violence. However, for safety reasons, a study cannot expose participants to the risk that serious types of violence presents. As a result, researchers must identify similar but benign behaviors that can help us understand more aggressive behaviors without harming participants.
