Most of the time, preventing a bad situation from happening is a much better option than taking a risk. This is true in hiring people to sensitive position, in getting household help, or in employing a nanny to take care of your child. It can also be helpful in deciding to resolve a conflict wherein you have to know the deceitful person. There are also situations wherein knowing a person's tendencies, like in committing crime, stealing money, hurting kids, or giving up when the going gets rough, could result in unpleasant consequences that you cannot afford to happen. A lie detection test is the closest we can get to help us prevent these things from happening to us. More information on lie detector test on http://www.liedetectortest.uk/polygraph-test/.
A lie detection test with the use of a polygraph machine may be the answer. Although it may not give 100 percent accuracy, the result can still give us an idea of how to handle the situation by weighing the chances or putting safety features in place.
However, there are people considered truth wizards or human lie detectors, unique individuals indeed, who know with uncanny certainty when people are lying. They are able to do this by being able to see subtle signs that manifest in people's faces and behavior.
It is said that this ability to tell whether a person is telling the truth or not can be taught or learned. There are truth wizards that did not go through any training at all, but may have probably developed the ability through sheer practice and the innate knowledge and understanding of that power. They are able to see the subtle and fleeting expressions in the human face and almost imperceptible body language that may evade scrutiny and detection by ordinary people. The coined term for that is micro-expression. And studying the ways truth wizards or human lie detectors are able to do this can open the key to understanding human behavior, expressions, and tendency to lie.
