MIT Researchers Sent Applications to a Selection of Job Ads

MIT researchers sent applications to a selection of job ads. Using fictitious names that sound (particularly to whites) like typically white or black names, their findings included all the following EXCEPT:

A) applicants with "white-sounding" names were 50 percent more likely to be contacted by employers than applicants with "black-sounding" names.
B) after increasing the job credentials of the tester-applicants, white applicants were far more likely to get call-backs from the presumably mostly white employers than black applicants.
C) being black with eight years of job experience was necessary to get the same treatment as a white applicant with no experience.
D) being black with three times the job credentials as whites had no impact on number of call-backs applicants with "black-sounding" names received.
