Several of the searches given as examples of racial bias are already in a feedback loop; if everyone on the Internet starts writing articles saying 'OMG search for unprofessional hairstyles for work and look racism' then it shouldn't come as a surprise that the first results for otherwise innocuous phrases become skewed, and removing this so-called bias actually requires direct intervention. Although if one actually compares the results for [un]professional hairstyles for work there doesn't seem to be any negative bias; black people are well-represented in both result sets.
