Bullying: Repeated actions or threats of action directed toward a person by one or more people who have (or are perceived to have) more power or status than their target in order to cause fear, distress or harm. Bullying can be physical, verbal, psychological or any combination of these three. Bullying behaviors can include name-calling, obscene gesturing, malicious teasing, rumors, slander, social exclusion, damaging a person’s belongings, threats and physical violence.
- Elementary school version: When a person or a group behaves in ways—on purpose and over and over—that make someone feel hurt, afraid or embarrassed.
Bystander: Someone who sees bias or bullying happening and does not say or do anything.
All forms of bias can be both explicit (aware, voluntary and intentional) and implicit (unaware, involuntary and unintentional). All manifestations of bias and discrimination can be both personal (an individual act of bias, meanness or exclusion) or systemic (policies and practices supported and sanctioned by power and authority and that benefit some and disadvantages others).
The specific, pervasive systems of oppression and marginalization described in some of these definitions are upheld by institutionalized, cultural and historical ideologies and discrimination. These systems exist simultaneously, compounding the harm to individuals with multiple marginalized identities. Individual acts of prejudice and discrimination are informed by and perpetuate these systems, which exist regardless of individual prejudices and interpersonal acts of bias.
