This document summarizes a study examining how courtesy stigma affects the academic performance of children from single mother, African American households. It reviews literature on teacher expectancy effects and self-fulfilling prophecies. The study uses regression analysis to examine the relationship between household type and poor academic performance, controlling for variables like race, sex, and income. While some statistical significance was found for single father households, the study notes limitations and concludes that one cannot fully understand single African American mothers through stereotypes or assume capability based on background.
