Brett Kavanaugh’s accuser has alleged central evidence against him – a successful polygraph test. But it might not be as foolproof as she thinks. The Washington Examiner reports:
Reports about the woman who claims Supreme Court nominee Brett Kavanaugh sexually assaulted her decades ago state that she took a polygraph test that deemed her to be “truthful.”
But experts interviewed by the Washington Examiner doubt the significance of that finding, and assert that such tests are unable to assess at all whether a person is lying or is truthful.
Thomas Mauriello, a former senior polygraph examiner who worked at the Defense Department for 30 years, said in an interview Monday that polygraph tests merely detect when a subject is experiencing a physiological reaction — like perspiration or an increased heart rate — to one or more questions.
The tests don’t, he said, determine whether a person is lying or attempting to deceive. Instead, the results have to be interpreted by the person administering the test.
Congress will be hearing from both Ford and Kavanaugh.
