Paula,
The polygraph can be useful for interrogating suspects who do not understand that the lie detector is a sham. People who think that the lie detector will detect any deception may choose to be more honest than they would otherwise be.
However, polygraph "testing" has no scientific basis (https://antipolygraph.org/articles/article-018.shtml). The procedure is inherently biased against the truthful, and deceptive persons who understand polygraph procedure can use simple techniques called countermeasures to pass.
