Common Methods of Lie Detection And Their Effectiveness

As Ayn Rand one said, “People think that a liar gains a victory over his victim. What I’ve learned is that a lie is an act of self-abdication, because one surrenders one’s reality to the person to whom one lies, making that person one’s master, condemning oneself from then on to faking the sort of reality that person’s view requires to be faked… The man who lies to the world, is the world’s slave form then on… There are no white lies, there is only the blackest of destruction and a white lie is the blackest of all.” Lying is one of the biggest epidemics to not only strike our nation but also our world. Man has lied since the dawn of sin, from the deceptive excuses for devouring the fruit of evil all the way up to problems our century faces. Almost every person, if not every person to walk this earth has preformed this devilish task at least once.

The question is not if one lies or how one lies but rather how to determine when one is lying. This is done through establishing a baseline and then comparing an individual answers to the established baseline. Asking the individual a serious of questions that are implied and that you know will be answered truthfully forms a baseline. They baseline acts as a guideline to how the individual normally responds to questions whenever they are telling the truth. Whenever reactions differ from the baseline you can assume that an emotional change has happened, this differ in reaction is what is normally attributed to deception or lying. The six most common ways of establishing this baseline are through facial analysis, reaction time, statement content analysis, brain imaging, thermal imaging, and through a polygraph test.
