“The Meaning of Race”

Article: Kirschenman and Neckerman (1991) uncover what race MEANS for a segment of society: employers.

After conducting their analysis, they find that “statistical discrimination” is the result of “pure discrimination” of employers who use racial markers as a SIGNAL of WHAT (there are two concepts)?

In your discussion, please include a list of the aspects Kirschenman and Neckerman found were SIGNALED by the race of the applicant.

(Hint: there are two signals, and each of these signals indicates a list of aspects; remember these are not real, they are stereotypes about race. As the authors show, this is what race means to employers.)
