The FBI teaches you lie detection, people reading and intelligence skills

Chapter 40 Interrogation Techniques (3): Determining Responses, Applying Pressure ([-])
Hands can help adjust the state when you feel uncomfortable.Actions such as wrapping fingers indicate anger, but it doesn't necessarily mean deceit.Some people habitually gesticulate in conversation, but when their gestures are unusual, they may be lying.Under normal circumstances, when people talk, they put their hands in front of the body, close to the face, or make a spiral swing; when people express confusion, they shrug their shoulders.If someone peeked at your diary and tried to lie to cover it up, he might mutter and point his finger in the other direction: "Isn't that over there?"

Gestures can also hint at what the other person is really thinking, such as wanting you to leave or telling you to stop.A flick of a finger or the side of a palm across a tabletop means, "The conversation is over." If your hand draws a stop sign in the air, even if it's not intentional, people will think you're trying to shut him up .

The same goes for legs and feet.It is possible to observe how someone's legs look when they are relaxed.Once he deviates, it shows that he is under pressure.

Finally, I would like to emphasize that the speed of changing postures can reflect the speed of emotional changes. Of course, it may also be that her seat is not comfortable. At this time, the reason should be quickly caught and judged.

§§§Section [-] Applying Pressure, Digging for Truth

Once you've identified the other person's natural responses, such as eye-rolling patterns, relevant body language, speaking style, etc., you can then use these to apply pressure.

In fact, people often do this in their daily life. Asking some sensitive questions, yelling at each other, etc. will have this effect.But in these cases, the pressure is usually of little use.For example, the distance at which people talk between people varies across cultures.Americans tend to keep a long distance from strangers.For people who are more familiar, Americans will shorten the distance.When we are very familiar with someone, we allow him to cross the line of about half a meter, and are more receptive to approach from women, but not so easily with men.When you invade someone's personal space, whether on purpose or not, it can make them feel uncomfortable.There are two principles of putting pressure on the opponent:
Principle [-]: Throw away colored glasses!You're probably the visual type, so it's easy to notice changes in someone's face and body, but don't forget about auditory and sensory changes, too.

Principle Two: Applying pressure involves an emotional and mental interaction.Often physical discomfort or insulting language can make you emotional, and the interrogator will use your natural reflexes to ask questions that require you to think.The emotional response to these questions will take away your ability to think normally and lead to more stress.They may also ask a barrage of questions that you don't know about, and as cognitive faculties are called upon to dig out the answers, you feel strongly: a lack of confidence and thus aroused emotion.Likewise, the interrogator can tell if you are stressed by judging your mental state.Of course, even not knowing someone's natural reactions can create a lot of stress.

When you put pressure on someone with the intention of obtaining information, you need to follow a predetermined plan and ask questions that allow you to understand the other person's natural reaction.

Below, we look at an example of how a professional uses this coercion to apply pressure to unearth truth and character traits.

Paul works in customer training for a computer company.That computer company specializes in customizing products for governments and large corporations.Paul won a job offer to do security checks with the company's client in the Federal Intelligence and Security Service.When Paul learned that there was a higher salary in that intelligence unit, he applied to become a security analyst for that unit.

During two rounds of rigorous review interviews, the interviewers tried their best to test him on every level, using various stress-inducing techniques to constantly provoke Paul's emotions.

They clearly know that Paul has a Ph.D. and his IQ is beyond doubt, so why ask some naive questions that elementary school students can easily answer?Why did you have to measure your blood pressure, and you were strangled so tightly that your arms turned purple?Paul had honestly told them he never drank, so why kept asking her where she got over her alcoholism?Why tie Paul to the tester and delay starting the test?
One of them ended when Paul couldn't bear it and had a big fight with the interviewer, and another time Paul was so tormented that he couldn't cry.

Throughout, Paul's answers are honest.Obviously, whether it is a fact is not what the interviewer values ​​at this moment.They already knew all the facts about Paul. The only thing they didn't know, and the only thing these tests could tell them, was how Paul handled stress.More importantly, how much pressure Paul can bear.

Interviewers also use outward signs of intimidation, such as small, closed rooms, strapping people to testers, and a series of well-crafted questions that wreak havoc on a person's self-esteem and confidence.Using these questions, interrogators once forced Ted Buddy to confess to more than 30 murders.After constantly beating his self-esteem, the interrogator finally forced him to make a full confession, and he even confessed all the murders that the interrogator hadn't contacted him.

Did those interviewers really use some inferior methods as Paul said?of course not.First of all, they probably didn't tighten the blood pressure cuff too much, and when the problem made Paul tense, the blood flow accelerated and the blood vessels dilated so that she "feeled" tight.When asked if he drank alcohol, Paul flatly stated that he never drank.This made them feel that Paul seemed to be hiding something on purpose.Because categorical words like "never" or "always" are usually a sign of disguising certain information. "I never drink" can also be interpreted as "I used to drink and now I don't drink" or "I don't drink myself and I hate people who drink."

Remember: professional interrogators don't act for no reason, and interrogators are good actors, they just usually have a single audience.Let's look at two exercises commonly used by the FBI.

Exercises to Identify Natural Responses

Goal: To perceive stress in reality.

step:

(1) Ask questions that you know the answers to.

(2) Observe the other party's reaction.

(3) Ask questions that require thought or elicit emotions (you may or may not know the answer).

(4) Observe reactions; monitor abnormal behavior.If there is an abnormality, it proves that the other party is under pressure.Note that signs such as fidgeting do not necessarily mean that the other person is stressed, only if the other person doesn't normally act like this should be assumed.

pressure exercises

Goal: Determine if someone is hiding the truth.

step:

(1) Ask questions to which you know the answers to determine natural responses.

(2) Touching on topics that make the other party uncomfortable.

(3) Observe abnormal behavior (facial, physical, auditory, ritual, etc.).

(4) Create pressure.

(5) Further pressure; pressure through specific words, mannerisms, and topics.

(6) Release the stress; return to words, mannerisms, and topics that make the other person feel at ease.

(7) PRESSURE AGAIN.

During an interrogation, the interrogator usually repeats steps 4-6 until the other person is exhausted from being questioned, has a broken will, and finally tells the truth.The same can be done with a lying spouse.In business situations, though, the use of pressure must be treated with caution, and you certainly don't want to make your clients hysterical.When it is confirmed that the other party's emotions have been aroused, it should be immediately transferred to the stress release stage.It is enough to know what the opponent fears, such as loss, bad public image, product design flaws, etc., and how to alleviate the opponent's pain.If the customer is driven to the point where they can't bear it and go crazy, they will lose opportunities for cooperation, orders, and recognition, let alone long-term cooperation.

Sometimes, you can tell almost instantly if someone is faking it.For example, if you ask a question that requires thinking, and the other party answers without thinking, then this response may not necessarily be a lie, but it can usually be regarded as a signal that the other party deliberately conceals certain facts.For example, you ask a car salesman if the engine in the car you just drove is in good shape, and he immediately says yes.Then this implies that the engine performance is really flawed.If you feel that discussing this topic will make the other party unhappy, then it is better to change a car.

Once the natural responses have been established, it is possible to discern what behaviors, words, and questions hit the other person's weak points.When FBI experts teach interrogation techniques, the following analogy is often mentioned: If I were to attack a samurai in full armor, then I would attack at random, or observe his defenses to find the most vulnerable places, and once found I will concentrate on attacking his weaknesses; in the market, you should not only find out the opponent's pain, but also learn how to relieve the opponent's pain. aggravate the other's pain.A deep understanding and skillful application of these two methods is the key to gaining an advantage in business activities.

In interrogation school, cadets do this exercise: Throw objects at a wall and see what sticks to it.Throwing is based on ignorance of these objects and probability theory.By learning how to identify natural responses, you can more clearly find out what questions to ask.The use of interrogation techniques depends on the trainee's good information analysis ability and intuition ability.
