Influence of case facts on blind scorers of polygraph tests

Abstract

"The first author (Shurany) was asked by a client if the Quality Control Reviewer should be provided with the facts of the case before blind scoring the physiological data recorded on the polygraph charts related to that polygraph examination, and whether it would have an influence on the reviewer’s judgment and evaluation. Th e question generated this research study, which was preceded by a fi eld study by Dror & Rosenthal (2008) that employed meta-analytic procedures to determine the degree of reliability and bias ability of forensic experts."(...)
