This shows that race is not the predominant factor when companies/individuals make a decision, but name is still important as it's the first thing that people see before meeting in person. It provides some background information on the applicants. This also reminds me of signing up for different discussion groups in middle school, I also felt more secure when I see names that sound culturally familiar to me.
