Applicants for the national security workforce are required to provide detailed personal information as part of the background investigation process to adjudicate their eligibility for a security clearance. As a result, during the course of the personnel vetting process, an individual's race or ethnicity, gender, gender identity, sexual orientation, and neurodivergence may be knowable or inferred by the personnel conducting the investigations and adjudications. Human judgment and biases that manifest themselves in other employment or social contexts have the potential to contribute to bias and sources of inequity in the human element of the process of determining security clearance eligibility. The authors explore the potential for related bias or sources of inequity within the federal personnel vetting process. Such potential biases and inequities could inhibit the U.S. government's goals and abilities to hire and maintain national security personnel with diverse backgrounds and perspectives.
