Four Things To Notice As You Learn How To Detect Lies

Four Things To Notice As You Learn How To Detect Lies

People’s fascination with lie detection has been demonstrated by the popularity of TV shows and movies such as Lie To Me and The Negotiator, where complex concepts such as micro-expressions and eye movement patterns are reduced to sound-bytes that make them easy for public consumption. While it is true that the more time and energy you put into studying lie detection techniques the better a “people reader” you will become, you can also pick up some fast and easy techniques to help you learn how to detect lies.

To begin detecting dishonest statements, it is helpful to get a feel for the overall landscape of lie detection. The broad areas you will want to pay attention to are body language, emotional signals, interactions which reveal guilt or discomfort, word choice and physiology.

You may want to watch this video to have a brief idea first:

Body Language

When noticing body language for the purposes of learning how to detect lies, start contrasting someone’s non-verbal communication by establishing a baseline of veracity. One way to do this is to make a statement that you know to be true and then mentally record how the subject’s body looks when they respond. For example, if you know the person went to Hawaii for vacation, state firmly, “So you went to Hawaii last month for a week. Fantastic!” Then state something that you know to be false: “And you took a cruise there. What an experience!” Watch as they non-verbally disagree and then watch their body language as they correct you. Now you have two mental snap shots of their “yes” and “no” that will give you a baseline for further calibration. In the future, when you make “yes” or “no” statements or questions, you should see the same physiology as the baseline that you established. If not, there could be deception involved.

Here is some general physiology people display when they are lying:

  • Stiff or limited hand and arm movements
  • Decreased eye contact
  • Increased hand contact with face
  • Body language does not match words

Emotional Signals

The way people express emotions can reveal whether they are being honest or not. In this category, simply becoming aware of abnormal expressions of emotions will help you learn how to detect lies.

  • Watch for delayed emotions
  • Notice emotions that last longer than what is natural for the person
  • Emotional expression is limited to one area of the face rather than the whole face

Word Choice

Our choice of words can reveal dishonesty as well. When a person is creating a deception, they need to distance themselves from the lie due to the cognitive dissonance created by the deception. To do this, they alter how they represent the lie to themselves, and this representation will cause a waterfall effect on their language.

Of special and recent interest, even our pronoun usage can reveal whether we are lying or telling the truth. According to Dr. James W. Pennebaker of the University of Texas at Austin, pronouns such as “I,” “me” and “my” show ownership of a statement. Therefore, when someone is lying, they will use these pronouns less, as they are further linguistic signs of distance from the lie.

  • A person being dishonest will make less direct statements.
  • They will often repeat your exact words.
  • Unnecessary details are added to the deceptive statement.
  • A statement with a contraction like “wouldn’t” or “didn’t” is more likely to be truthful than the uncontracted form.
  • Liars will interject words like “actually,” “to be honest,” or “frankly.”
  • An abrupt change of subject is another sign of dishonesty.

Physiological Symptoms

Much of what has been written previously about how to detect lies is within the conscious control of the deceptive person. There are, however, “tells” that are generally outside a person’s consciousness that are harder to repress or control.

  • Sweating can be a sign of lying.
  • Lying can cause an increase in the secretion of the hormone adrenaline. This causes a fluctuation in saliva production, which causes the person to first have to swallow more and later clear their throat due to dryness.
  • Since the heart is usually beating faster, a person being dishonest will breathe faster.
  • Decreased blinking of the eyes can also be a sign of lying.

While lying is prevalent, it does not come naturally. Deep down, most people want to tell the truth, even when they feel they need to lie. To accomplish this feat, the brain goes into cognitive overload in order to provide the resources necessary to pull off the lie. Since the mind and body are connected in various ways, it makes sense that when the brain has an increase on its cognitive load, the body will show symptoms. The single key to becoming good at lie detection is to look at the big picture (all of the above indications) in relation to the person you are observing. Make sure you account for cultural norms and personal idiosyncrasies by gaining rapport with the individual you are studying. Keep an open mind and stay relaxed, and you will be on your way to becoming a master lie detector!

8 Smart Home Gadgets You Need in Your House

We’ve all done it. We’ve gone out and bought useless gadgets that we don’t really need, just because they seemed really cool at the time. Then, we are stuck with a bunch of junk, and end up tossing it or trying to sell it on Ebay.

On the other hand, there are some pretty awesome tech inventions that are actually useful. For instance, many of the latest home gadgets do some of your work for you, from adjusting the home thermostat to locking your front door. And, if used as designed, these tools should really help to make your life a lot easier—and that’s not just a claim from some infomercial trying to sell you yet another useless gadget.

Take a look at some of the most popular “smart gadgets” on the market:

1. Smart Door Locks

A smart lock lets you lock and unlock your doors by using your smartphone, a special key fob, or biometrics. These locks are keyless, and much more difficult for intruders to break into, making your home a lot safer. You can even use a special app to let people into your home if you are not there to greet them.

2. Smart Kitchen Tools

Wouldn’t you just love to have a pot of coffee waiting for you when you get home from work? What about a “smart pan” that tells you exactly when you need to flip that omelet? From meat thermometers to kitchen scales, you’ll find a variety of “smart” gadgets designed to make culinary geeks salivate.

3. Mini Home Speaker Play:1

If you love big sound, but hate how much space big speakers take up, and if you want a stereo system that is no bigger than your fist, check out the Play:1 mini speaker. All you have to do is plug it in, connect, and then you can stream without worrying about any interruptions or interface. You can even add onto it, and have different music playing in different rooms.

6. Smart Lighting

Control your home lighting from your remote device. This is great if you are out and want to make sure that there are some lights on. It is designed to be energy efficient, so it will pay for itself over time because you won’t have to spend so much on your monthly energy bills.
