deception and deception detecting, an evolutionary advantage

a very informative article on the evolutionary aspects of deception and deception detection. currently it is possible to detect deception in near all cases in real-time. further i disagree the observation where the reported chronometric cues were replicated in relation to significant longer response latencies.

a more modern example relates to the case of the infamous confidence-trickster, frank abagnale jr., who is now an fbi financial fraud consultant. those who employ former “poachers” assume that people who are good at breaking the law are good at detecting when others break the law. this assumption is widespread, but at least in the case of deception, there is no scientific evidence to suggest that good liars are necessarily good lie detectors.

results indicate that the current paradigm is comparable to previous studies with regards to the participants’ self-reported experience of guilt, anxiety, and cognitive load during the task, and overall lie detection accuracy. In addition, previously reported chronometric cues to deception were replicated in this study, with significantly longer response latencies when lying than when telling the truth. moreover, as far as we are aware, this study is the first to provide evidence that the capacity to detect lies and the ability to deceive others are associated. this finding suggests the existence of a “deception-general” ability that may influence both “sides” of deceptive interactions.

open for discussion.

Both the ability to deceive others, and the ability to detect deception, has long been proposed to confer an evolutionary advantage. Deception detection has been studied extensively, and the finding t…
