I wonder how this new generation of lie detector works as the accuracy of this kind of product is always in question. Just like how lie detectors are inadmissible to the court.
PROS :
- See some kind of clues or hints on what the person is saying
- allows you to have a second opinion for yourself
- more discrete compared to a big lie detector - the person in question won't know you are observing them
CONS
- Accuracy - this product will only work if it really do what it supposed to do but since humans are too complicated it will vary from person to person.
