Introductory sociology classes afford instructors an opportunity to expose students, often from a variety of backgrounds and majors, to the sociological imagination. In this article, I describe how the use of secrets from a popular website, PostSecret.com, can help teach students about the sociological imagination and incorporate biographical examples in explanations of broader social trends and sociological concepts. I present results from a survey of students in an introductory sociology class in order to gauge their response to the use of anonymous secrets. Results reveal that over 75 percent of students indicated that PostSecret helped them understand the sociological imagination and learn sociological concepts, 93 percent of students reported that it helped them understand course content through the use of examples, and 69 percent indicated that it helped them remember important concepts. Students also indicated that the discussion of secrets helped them recognize their own assumptions about the social world and provided them with a perspectives different from their own.
