Detection theory allows one to quantify the ability to discern between information bearing patterns and random patterns that causes confusion in the patterns. In electronics, detection theory is often called signal recovery.

One of the earliest devices was developed in 1885 by Cesar Lombroso
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.

a theory predicting how and when we detect the presence of a faint stimulus ("signal") amid background stimulation ("noise"). Assumes there is no signal absolute threshold and detection depends partly on a person's experience, expectations, motivation, and level of fatigue.
The scientific theory behind cell theory is that it explains the fundamental properties of all cells. The cell is the basic unit of all living organisms.
