Background Screening is Great Deterrence
You would expect pre-employment background screening to prevent hiring someone with a criminal background, or to provide information about the truth of a resume. There is additional benefit to be realized by advertising that background screening is a normal part of your hiring process. Most applicants will then either provide a more complete and truthful application and/or resume, or won’t bother to apply at all (especially if they do have a criminal background). This can save employers time and money in the hiring process, before they even begin reviewing applications!
