Lie detection technologies are not especially accurate; the polygraph test is the iconic method and is considered unreliable by the US National Academy of Sciences. It measures quantities like heart rate, which can fluctuate in response to stress. This stress may be the result of lying, or the result of taking a polygraph test, which is itself stressful. Other lie detection technologies exist, such as voice analysis, but no such method has been proven reliable.

IQ tests
Not necessarily. Urine tests and blood tests measure different things and have different detection windows. Passing a urine test does not guarantee passing a blood test, as they are used to detect different substances and levels of substances in the body.
IQ tests and achievement tests measure different things in learners. Achievement tests only measure what the student has learned in a particular subject while IQ tests measure how well you will do in the world.
