To investigate whether it helps to have a "white-sounding" first name when looking for a job, the researchers sent 5,000 resumes in response to ads that appeared in magazines. The resumes were identical except that 2,500 of them had "white-sounding" first names, such as Brett and Emily, whereas the other 2,500 had "black-sounding" names such as Tamika and Rasheed. Resumes of the first type elicited 251 responses and resumes of the second type only 169 responses. A button hyperlink to the SALT program that reads: Use SALT.
