One white man and one black man would pose as job seekers without a criminal record, and another black man and white man would pose as job seekers with a criminal record. The negative credential of prison impaired the employment efforts of both the black man and the white man, but it impaired those of the black man more. Startlingly, the effect was not limited to the black man with a criminal record. The black man without a criminal record fared worse than the white man with one."
