Abstract or Description
The General Expertise Framework (GEF) explains the phenomenon that regardless of domain, experts have certain features in common, such as a high volume of accumulated practice, performance consistency across time and situation, accuracy of calibration between perceived and actual performance, and well-developed metaawareness which facilitates adaptability of performance in response to feedback.
Interpersonal Deception Theory (IDT) and Activation-Decision-Construction- ActionTheory (ADCAT) present lying as a cognitively challenging act requiring skill to perform
well. So, it makes sense that deception should show the same features as other areas
of expertise. However, this has never been systematically tested. This programme of research involved four empirical studies, across a range of channels and contexts including interactive in-person interviews and online written deception, which sought to answer an overarching question. Can deceptive performance be conceptualised as a skill, as defined by the GEF? To obtain an objective measure of deceptive performance uncontaminated by possible receiver biases, a Matrix of measures was constructed
which included only the most reliable cues. The results suggest that deception is a particular example of expertise, learned in a wicked environment, poorly practiced by most and situationally contingent. Expert liars show an effect of practice, but a high volume of accumulated practice is not sufficient to confer expertise, rather focused, strategic use of lying is required. Expert liars demonstrate superior calibration of perceived and actual performance even though feedback on lying is almost nonexistent in everyday life. This may be why responsiveness to feedback is the most challenging element of expertise in the domain of deception. The unique insights provided by the mixed-methods approach means future research must continue to explore these techniques.
