Chapter 31 Information Method Lie Detector: Don't Miss a Trace of Clues

From the perspective of informatics, lying means hiding true information or providing wrong information.Therefore, to detect lies is to find true information or expose false information. The FBI has learned from years of practical work that there are four ways to easily decipher lies.

§§§The first section traces back to the original information, so that the lie has nowhere to hide
The FBI pointed out that one of the usual tricks of liars is to create sources of information, and at this time, the method of tracing the original information must be used.As long as the hidden information is uncovered or exposed from the source of the information, then the lies will be self-defeating.

For example, the parents of some examinees are often deceived when dealing with their children's admission to higher education. The reason is that the parents listened to the liar's rhetoric and never thought of checking the original information-ask the relevant department of a certain school that the liar said , Is there an unplanned enrollment quota, and if so, how much is the fee... If the parents of candidates ask a certain school, they will be able to easily see through the scammer's tricks.

§§§ Section [-] argues for opposing information, allowing the truth to surface
There is a saying in the West: "The enemy of my enemy is my friend".At present, there is a similar saying in the business world: "There are no permanent enemies, and there are no permanent friends."

The FBI pointed out that it is often easy to get some more real information from the opposite side of the other party.Of course, it is also necessary to analyze the information provided by these "enemies of the enemy", and we must not accept it in a daze.

In addition, according to the research of information scientists, ordinary people always feel more credible to hard-won information, or to relatively alternative information, or to unexpected information.Generally speaking, most of the information obtained from the "enemy of the enemy" is the information that was obtained after a lot of trouble. It happened that I heard the information that shocked me deeply. It is "real information", but in fact, it is still necessary to remain calm and analyze this kind of information.

§§§ Section [-] repeats key information, common practice of the FBI

For some key information or suspicious information, the FBI's usual practice is to adopt the method of repeating key information.Specifically, there are several methods:

1. Choose different times to repeatedly "review" the same information

For example, if you asked the question "What exactly do you do in that company?" in the morning and were confused about the answer, try asking the question again at a different time.I am also particular about the time of the change. This time, you might as well choose to ask questions at noon, evening and other times when most people feel tired.Or you can choose that the other party is more relaxed, or ask questions suddenly when you are concentrating on other things, so as to achieve the effect of being caught off guard. In this way, you can often get real information.

2. "Recheck" the same information from different channels

In general, information can be communicated through different channels.For example, talking face-to-face with the other party is a channel, making phone calls is also a channel, and sending emails online is also a channel, and so on.

In the face of doubtful information, "rechecking" the same information through different channels can not only get more information to confirm the reliability of the known information, but more importantly, the liar's mentality when using different channels The burden is not the same.For example, using the Internet and using the telephone, the psychological burden on the liar is much smaller than that of face-to-face conversation.Therefore, for some important information, even if it is not considered from the perspective of seeing through lies, it is indeed necessary to verify and verify through different channels.

3. Use different roles to "review" the same information

For example, if you have doubts about the sales someone provided, you can change roles, such as asking someone else to ask the question again, and see if the information obtained by different people is the same twice.

§§§The fourth section compares similar information, the golden technique in the field of deception

As the saying goes, "Don't be afraid of not knowing the goods, but be afraid of comparing goods." The same is true in the field of deception, which means that because you know too little relevant information, you can't judge whether it is good or bad.By shopping around and knowing more relevant information, you will naturally start to have the ability to identify.The same is true for lies. If you feel uncertain about the information provided by the other party and do not know whether it is true or false, then the more common choice is to expand the relevant information.

For example, when the other party uses very professional language to describe how a certain "high-tech product" is easy to use, and therefore the price is correspondingly high, it is indeed difficult to judge the authenticity for a while, so the most correct way is to quickly consult the information and Experts and other ways to expand relevant information.After possessing a wealth of information, and then look at the information provided by the other party, you will already have the vision of a half-expert, and you will not be easily deceived.
