Journal article: Hiring discrimination in France is now well documented thanks to accumulated evidence from correspondence testing. The results support that discrimination is widespread and strong: on average, this amounts to a 40 % lower call back rate for ethnic minorities. Such discrimination does not appear only because of a distaste of employers towards minorities; the ability to accurately anticipate the skills and characteristics of candidates from minorities also plays an important role. This allows to design new tools to restore equal treatment, based on enhanced information about applicant's abilities.
