# 52. Manipulation of Memory ## 52.5. Methodology/Refinements/Sub-species ### 52.5.29. Stereotypical bias This is the bias in which the memory is distorted towards stereotypes (e.g. racial, gender etc.). For example, "black-sounding" first names being deliberately associated with criminal activity by a racist manipulator. The idea is that the victim builds up and uses the stereotype designed and delivered by the manipulator. Advertisers and social and political manipulators constantly use stereotyping to trigger a "memory" in their victims. The stereotypes are built up over a period and then used repeatedly. Stereotypes can be something as relatively harmless as "the happy middle-class family on holiday" but they can equally be some derogatory racist slur.
