New submitter sfcat writes "Companies, headhunters and recruiters increasingly are using social media sites like Facebook to evaluate potential employees. Most of this is due to a 2012 paper from Northern Illinois Univ. that claimed that employee performance could be effectively evaluated from their social media profiles. Now a series of papers from other institutions reveal exactly the opposite result. 'Recruiter ratings of Facebook profiles correlate essentially zero with job performance,' write the researchers, led by Chad H. Van Iddekinge of FSU (abstract). Not only did the research show the ineffectiveness of using social media in evaluating potential employees, it also showed a measurable biases of the recruiters against minorities (African-American and Latino) and against men in general."
