Why do people take polygraph / lie detector examinations? Well, typically the reason why a polygraph test is taken is because the person needs to prove they are being truthful usually in relation to a (false)
accusation which has been made. When someone is under suspicion of wrongdoing there may be no other way they can prove they are being truthful, so they take a lie detector test.
A fairly common reason for taking a test is because someone has been accused, or is under suspicion of cheating in their relationship with their partner, often known as infidelity testing. There is a strong association between polygraph tests and infidelity as many daytime television shows would test people for this very reason, often for entertainment purposes. However, the reality is that there is a wide range of reasons why tests are conducted.
Another typical reason is an accusation of theft, either in the home or at a workplace. Testing works particularly well when there is either only one, or a small number of people who could have committed the theft. Thereby not only identifying the guilty party but allowing the innocent parties to clear their names.
Other reasons polygraph test are taken include:
- Domestic disputes
- Accusations of physical assault
- Accusations of sexual abuse or sexual assault
- Family law issues
- Pre-employment screening to verify trustworthiness of potential employees
- Workplace or employee testing
- Business disputes
- Sporting tournaments
- Fraud and/or bribery
- Addiction issues
- Investigations
- Media reasons
Polygraph testing can be conducted whereby serious crimes have been committed. Two suspects in high profile murder cases in Ireland, Richard Satchwell (in relation to his wife Tina) and Ian Bailey (in relation to Sophie Toscan du Plantier) both spoke publicly about taking a polygraph test to clear their name. Both were offered the opportunity to take a test, both declined to do so.
