The interpersonal deception theory contends that there are more than 18 different instances where a person who wants to deceit can actually attempt it. They refer to specific situational instances that enable someone to try and deceit to cause a loss of focus. However, the actual deception theory is intrinsically connected with the interpersonal deception theory. Therefore, the elements of it are basically broken down into what constitutes a deception, and in what instances the deception is most likely to OCCUR. 

In modern forensic psychology scenarios the IDT is the basis of the many TV shows about criminal profiling that we see today. This is because the IDT explains five ways in which we can DETECT deception in people. These are studied from the point of view of how us, as primitives, were able to instill in others fear, warning, compassion, or anger, without formal speech. Hence, deception can be detected in these non-verbal scenarios:

• face- a change in the musculature of the face such as wrinkling, clenching, or looking SEEMINGLY stressed, or detached. 
• body- TRYING to touch, or asking not to be touched, keeping or breaking close PROXIMITY boundaries. 
• gaze- the way in which the person moves and uses the eyes to convey a message
• gesture- a sudden change in the primary expression

Therefore, all these serve as basic tenets to determine the possibility and plausibility of deceit in modern communication.
