This document discusses two types of characterization used by writers - direct and indirect. Direct characterization tells the audience about a character's personality directly through statements from the author. Indirect characterization shows a character's personality through their speech, thoughts, actions, physical appearance, and their effect on others, allowing the audience to infer the personality themselves in a way that mimics how we learn about people in real life. The document advocates that writers most often use indirect characterization techniques through STEAL - speech, thoughts, effect on others, actions, and looks.
