This book studies how documentaries, and factual media in general, can contribute to the reduction of social stigma and prejudice. It adopts models from social psychology, media studies and cultural studies and is intended for scholars and media makers who aim to increase social inclusion and diversity by deconstructing harmful boundaries between social groups. Such boundaries may be based on the stereotyping of ethnicity, culture, age, dis/ability, gender and sexual orientation, for example. The first part of the book outlines the functionality of stereotypes as essential processes for social cognition both in real life and during documentary viewing. The second part establishes a classification system for stigmatising media stereotypes and formulates a methodology based on critical discourse analysis to analyse them in narrative and audio-visual representations. The third and final part of the book conceptualises a set of methodologies to reduce stigmatising stereotypes. These methodologies are based on 1) representations that prompt perspectival alignment with screen characters, and 2) the perceived salience of multiple, intersecting social identities.
