The polygraph is an instrument of great sensitivity and precision that records physiological variables in a person’s body. A professional evaluates the results to determine if the person is lying or telling the truth about a particular questionnaire.
The polygraph has three main uses:
- Pre-employment tests (for recruitment)
- Routine tests (periodic evaluation of staff)
- Specific tests (to determine participation in fraud, robbery or any illegal act)
