Lying people's behaviours
Deception gains a slight edge over deception detectionwhen the interactions are few in number and are amongstrangers. If you spend enough time with the people youinteract with, they may leak their true intent throughtheir behaviour. However, when interactions areanonymous or infrequent, behavioural cues cannot beread against a background of known behaviour, somore general attributes must be used. Because of thenegative consequences of being detected, people areexpected to be nervous when lying. In response toconcern over appearing nervous, people may exertcontrol, trying to suppress behaviour, with possible sideeffects detectable by the listener such as a planned,rehearsed impression. Lying is also cognitivelydemanding. You must suppress the truth and constructa falsehood that is plausible, then tell it in a convincingway and remember the story. Cognitive load appears toplay the biggest role. When lies are not well-rehearsed,people have to think too hard, and this causes severaleffects, including overcontrol that leads to blinking andfidgeting less and using fewer hand gestures, longerpauses and higher-pitched voices. Of course, ifself-deception is involved, you are less likely to give offthe normal cues of lying that others might perceive.
