Can Poker Players Fool Lie Detectors? Robbi Jade Lew's Polygraph Test

Poker player Robbi Jade Lew passed a polygraph test on October 14, 2022, denying questions about analyzers, collusion, and other cheating methods. The test results have sparked debate about the reliability of lie detectors. Some believe that poker players can easily fool lie detectors, while others point out that polygraph tests can be inaccurate for those taking antidepressants, which Robbi regularly takes.

Polygraph tests are generally considered to detect lies in 90% of cases, although some Twitter commentators reduced this effectiveness to 80%. In comparison, professional profilers detect lies in only 55-60% of cases. Experts in non-verbal communication and body language, who consult with special services and politicians, did not find any suspicious signals in Robbi's behavior during the test.

The polygraph test procedure is complex and involves several stages. The first stage includes formalities and ensuring the test is voluntary. The second stage is a pre-test conversation to relax the subject and build rapport. The third stage involves discussing the questions that will be asked, ensuring there are no surprises and that the questions are clear and unambiguous.
