Interpersonal Deception Theory (IDT) attempts to explain the manner in which individuals engaged in face-to-face communication deal with actual or perceived deception on the conscious and subconscious levels. IDT proposes that the majority of individuals overestimate their ability to detect deception. In some cultures, various means of deception are acceptable while other forms are not. Acceptance of deception can be found in language terms that classify, rationalize or condemn, such behavior. Deception that may be considered a simple white lie to save feelings may me be determined socially acceptable, while deception used to gain certain advantages can be determined to be ethically questionable. It has been estimated that “deception and suspected deception arise in at least one quarter of all conversations”.
