Roles in Bullying and Bias Incidents*

Target: Someone against whom mistreatment is directed.

  • In a study of 500,000 3rd to 12th graders, 17% of students reported that they have been bullied at least 2-3 times in the last month. [1]
  • Approximately 20% of young people report experiencing cyberbullying in their lifetimes. [2]

Aggressor: Someone who says or does something harmful or malicious to another person intentionally and unprovoked.

  • In a study of 500,000 3rd to 12th graders, 10% of students reported that they have bullied someone at least 2-3 times in the last month. [3] 
  • In a survey of 655 13- to 18-year-olds,  approximately 1 in 10 teens reported that they have cyberbullied someone online or by text message. [4]

Bystander: Someone who sees bias or bullying and does not say or do anything.

  • A study using classroom observations indicated that children and youth were present during 85% of bullying episodes, but intervened just 10% of the time.[5]

Ally: Someone who speaks out on behalf of or takes actions that are supportive of someone who is targeted by bias or bullying, either themselves or someone else.

  • More than half of bullying behaviors will stop in less than ten seconds when another student intervenes. [6]

*When discussing bullying and bias, it must be made clear that definitions are describing the person’s behavior in a given situation, not defining the individual. While the A World of Difference® Institute uses nouns (e.g., aggressor) rather than adjectives (e.g., aggressive) in describing the roles in bias and bullying incidents, the intent is not to label or typecast a person, but to describe the role that person is playing in a specific place and time.
