What is a Typical Worker? Stereotypes about Social ClassesIn processes of interaction actors have to carry through social categorizations of other persons and accordingly activate the corresponding stereotypes about these categories. In social psychology as well as in sociology most research focuses on ascriptive social categories, whereas concepts like strata or class remain to a large extent neglected. Our thesis in this article is, that these categories are well known in the population and therefore mentally accessible. Accordingly, they are activated in the appropriate situations and relevant for orientation in everyday interactions. On the basis of an online survey, we are furthermore able to show, that stereotype contrasts between classes are mainly shaped by socioeconomic characteristics and high-brow life style features and less by personality traits.Schlüsselwörter: Stereotype, Schichten, Klassen, Lebensstile, Interaktionen
