Artificial intelligence sounds like it could be hiring's Holy Grail: A completely automated system that maximizes application-sorting efficiency, minimizes HR labor and reduces the chance that bias could taint the hiring process. Despite its great potential, AI carries liability risks that HR pros must understand. Artificial intelligence software relies on computerized algorithms to sort data and analyze it quickly, without human input. Many HR departments now use AI programs to sort through résumés and applications to identify key words and phrases. Applications that meet an employer's screening criteria are then forwarded to HR for further review.
