How much do employers discriminate against applicants with black-sounding names?

See Merit, Excellence and Intelligence: An Anti-DEI Approach Catches On by Callum Borchers of The WSJ. Excerpt:

"In the months before and after Floyd’s murder, which triggered many of the DEI initiatives being scrutinized today, economists at the University of Chicago and the University of California, Berkeley sent 83,000 fake job applications to 108 companies in the Fortune 500. The overall response rate for applicants with distinctively Black names, like Antwan and Lakeisha, was 2.1 percentage points lower than for candidates with white-sounding names such as Chad and Meredith.

Results varied widely from one business to another. Most often, the response gap was so small that researchers couldn’t confidently say an employer favored one race over the other. In a few cases, the response rate was slightly higher for applicants with Black names."
