12 Angry Men Building Background Knowledge | Bias, Prejudice & Stereotypes

Help students explore how bias, prejudice, stereotypes, and assumptions can influence judgment before reading or studying Twelve Angry Men. This no-prep lesson gives students the background knowledge they need to recognize how people can interpret the same evidence differently—even when they believe they are being fair.

Students investigate the differences between bias, prejudice, and stereotyping, identify warning signs of biased thinking, and examine how bias can affect both individual and group decisions. They then apply their learning by creating a collaborative Bias Detective Field Guide.
