The issue of multiple testing in polygraph screening – implications for internal security

Marcin Gołaszewski

Abstrakt

Screening polygraph tests are most often conducted before a candidate is hired. Bayesian statistics help to better understand the real meaning of the test results obtained. Retesting also happens - usually when a candidate fails on the first attempt. In the article, the author considers various scenarios related to retesting and their consequences, including for the internal security of individual institutions and countries. He seeks optimal solutions so that testing procedures promote tightness in systems while remaining efficient and useful.
