Interpersonal Deception Theory

  1. What are the three deception strategies?
    • 1. Falsification -creates a fiction.
    • 2. Concealment -hides a secret.
    • 3.Equivocation -dodges an issue.

    *Most people believe they can spot a deception but IDT says they can not.
  2. Interpersonal communication is interactive (This is a Social Constructionist Theory, like CMM)
    • 1. Active participants in communication      constantly adjust their behavior in response to feedback from other participants. Interaction is the core of the theory.
    • 2. Strategic deception demands mental effort. Cognitive overload (when your brain holds too many things) may cause a deceiver to exhibit a nonstrategic display—this is called leakage.  Leakage (you leak something that shows yourstate of agitation) signals an internal state of agitation. Lying causes psychological arousal.
  3. Deception can have 3 aims:
    • 1. to accomplish a task.
    • 2. to establish or maintain a relationship.
    • 3. to save face or sustain an image of one or both parties.
  4. There are four message characteristics that reflect strategic intent:
    • 1. Uncertainty or vagueness
    • 2. Nonimmediacy, reticence or withdrawal (turning away, moving words from present to past tense).
    • 3. Disassociation (group reference, modifiers).
    •  4. Image protecting behavior (extra sincere, nodding, eye contact).
    • *All communication is intentional and goal directed. Deception is just more so.
  5. Truth bias
    we assume people are telling the truth. This gives deceivers the upper hand.
  6. Deceivers:
    Deceivers are usually more successful at sensing suspicion than respondents are at spotting deception. They usually reciprocate the mood and manner of the person they are trying to mislead. The deceiver has the chance to smell suspicion and then adjust.
  7. Othello errors
    truth tellers react the same way are deceivers when confronted with suspicion.
