Truth machines, formally known as polygraphs, have been the subject of debate for decades. But have you ever wondered when it is appropriate to use a polygraph in the workplace? Let's take a closer look!
The Value of Truth
Let's start by understanding what a polygraph is. It is a device that measures and records various physiological responses such as blood pressure, pulse, breathing and skin conductance while a person answers a series of questions. Although it is not infallible, the polygraph can be a useful tool when used correctly.
When Is It Appropriate to Use a Polygraph in the Workplace?
Using a polygraph in the workplace is a sensitive matter and must be handled with great care. In general, it may be appropriate in situations where fraudulent activity, theft or unethical conduct is suspected.
Of course, it is always essential to follow local laws and regulations regarding the use of the polygraph. In some countries, using this instrument requires the employee's consent.
Selection and Recruitment
One context in which the use of the polygraph may be considered is during selection and recruitment processes. In highly sensitive jobs, where security and confidentiality are paramount, employers may choose to use this tool to verify the truthfulness of the claims made by candidates.
Incident Investigation
Another scenario is when a particular incident is being investigated, such as a theft or a case of fraud. Likewise, the decision to use a polygraph should be based on the detection of suspicious behaviour, not merely on rumours or assumptions.
Protection Against False Accusations
Finally, the polygraph can play a defensive role. In order to protect an employee's reputation against false accusations, the polygraph can provide an additional degree of clarity and objectivity in an internal investigation process.
That is the reality of when it is appropriate to use a polygraph in the workplace. However, it is important to remember that it must always be used responsibly and with respect for the rights of the individual undergoing the test.
