10 Ways You Can Spot A Liar With Body Language

Sharing buttons:


we've all seen a loose cannon cop who

plays by his own rules annually slam his

hands on a desk and declare that a

suspect is lying but how many of us can

really tell when someone is lying in

person sure some people are just bad

Liars in general but when dealing with

someone with a decent poker face there

are still ways you can tell if someone

is speaking the truth in this video

we'll teach you 10 ways you can tell if

someone is lying to you we definitely

wouldn't lie to you about the fact that

you should definitely subscribe to our

channel then join our notification squad

it's the best way to get the latest

updates from the hub the eyes don't have

it while some people may claim that you

need to look a liar straight in the eyes

it turns out you may be better off

looking elsewhere outdated knowledge is

that people who look to their left while

speaking are likely to be lying well

people who glance to the right are more

likely to be telling the truth

this theorized link between lying and

eye movements was a key element of neuro

linguistic programming which sought to

teach people the links between eye

movement and thoughts

however psychology professor Richard

Wiseman from the University of

Hertfordshire conducted a study in which

he film volunteers and observed their

eye movements when they made false

statements as well as truthful ones he

concluded that there is no correlation

between eye movement and honesty so what

sort of movements should you be looking

for to see if someone's lying watch what

they do with their heads just before

they respond to your question a liar

might retract or jerk back their head or

tilt it to the side

any sudden head movements can indicate

that they're trying to think of an

answer quickly and it's not likely to be

a truth

blink twice for yes so okay if the way a

person's eyeballs moves don't tell us

whether or not they're telling the truth

are there any clues to be gained from

the eyes at all it turns out that what

you really want to look at are someone's

eyelids and how often they're opening

and closing

most people blink approximately five to

six times per minute or once every 10 to

12 seconds

however Liars blink differently at

different portions of their speech

according to the Journal of nonverbal

behavior wires actually blink less

frequently when they're lying to you but

then they're blinking increases in speed

up to eight times faster than normal

afterwards dr. Sharon Leal from

Portsmouth University conducted a study

in which she had one group of volunteers

take a test and the second group steal

an exam paper from an office and then

deny having taken it electrodes were

placed all around their eyes while they

were then asked to describe what

happened while the questions were being

asked the liars all blinked very slowly

however when it was their turn to speak

their blink rate went way up dr. Leale

believes that because it's often

difficult to come up with lies this

could explain why they blink so slowly

fidgeting your fidget spinner won't be

able to save you from being caught in a

lie people who aren't telling the truth

tend to fidget profusely so pay

attention to their body language they

may digit with their hands pick out

their clothing or fiddle with nearby


someone who is lying may also touch

their nose or ear or appear to have

their hands constantly around their

mouths in fact researchers studying the

effects of lying on fidgeting in humans

can predict with an overall 70 percent

accuracy whether someone is telling the

truth or not

the research team used full body motion

suits the Sam type used in films to

create cgi characters to monitor body

movements each suit contains 17 sensors

that register movement up to 120 times

per second they questioned their

volunteers while recording all their

movements and then tried to guess who

was lying and who was telling the truth

while small fidgety movements indicated

lying about 60% of the time full-body

fidgeting was the key to getting an 80%

accuracy rate in terms of life they also

found that the suit to work for guard

was of cultural background anxiety level

or cognitive load those are factors that

heavily influenced other truth detecting

methods such as polygraph tests

disconnect we can may a lot through our

body language and can even provide

someone with a simple yes-or-no answer

just by nodding or shaking our heads

Philip Houston Michael Floyd and Susan

Carr nasarah are former CIA officers

that wrote a book called spy the lie in

which they teach people how to spot

Liars according to the CIA trio our

brains are wired up to ensure that our

verbal and nonverbal behaviors match

this is so you don't accidentally end

off flipping off your neighbor while

calling out a friendly greeting however

if you're being deceptive sometimes your

signals get crossed and you may end up

nodding while answering a question in

the negative where shaking your head

while answering in the positive if you

try to say the word no and not it feels

really strange so you can imagine this

is not something that you would do

naturally if you were being honest this

trick works better if someone is giving

you a narrative response rather than a

one-word answer you'll also want to keep

cultural differences in mind just in

case you're speaking to someone who is

used to different gestures than you are

watch their hands you can also learn a

lot by watching someone's hands when

they speak you may have seen people who

can't seem to stop - speculating when

they speak and you may even be one of

those people yourself but when telling a

lie people often make very specific hand

motions that you can easily spot one

that we mentioned briefly before is

touching their face they may seem to

compulsively pickup their lips or tug on

their ears when faced with a question

they don't want to answer this triggers

anxiety for the liar and their autonomic

nervous system starts working to

dissipate that anxiety this can cause

the blood to drain from your face and

ears which may make them cold or itchy

hence the inclination to touch them they

may also hide their mouths their eyes

with their hands for brief moments it's

as if they're trying to hide their life

from the person they're speaking to

this is a subconscious movement that

most people don't know how to control so

it's a really good indicator that

they're not telling the truth these

forms of physical activity can often

help dissipate the anxiety caused by

lying so that's why our bodies do them

automatically repetition dr. Lillian

glass a behavioral analyst and body

language expert who has worked alongside

the FBI claims that repetition is a good

indicator of life not only is the person

speaking to you tried to convince you of

something that isn't true they're trying

to convince themselves as well they seek

to validate the lie in their mind by

repeating it this is also a way that

they can buy additional time in which to

gather their thoughts and come up with

works uses and this method is actually a

very effective way of lying

psychologist even have a term for it the

illusion of truth effect the more were

exposed to something the more we believe

it's true

everyone knows some facts that aren't

true but they persist in our minds

anyway because we've heard them for so

long think of things like we only use

10% of our brain or bananas are the best

source of potassium we know that these

things are false but it can be a

struggle to listen to our rational

greens and believe that if you've ever

found a marketing strategy used in

advertising repetitious the reason why

is because that often means it's


excessive talking Liars will often try

to bombard you with too much information

in order to make their story seem

plausible people telling a lie have a

flair for the dramatic and love

peppering a story with insignificant

details this will be information that

you didn't request and someone telling

the truth wouldn't think to mention by

overloading you with information Liars

hope to appear that they're being open

and honest by volunteering unwanted

details when they aren't getting bogged

down with mundane details you may notice

a lot of filler words in their speech as

well these are words such as or like

much like using repetition these words

are often used to buy them additional

time in which to make up their story

sure there are some people who just use

these filler words too much in general

because that's just how they talk but

for most people it's a form of stalling

while they wrap their brains trying to

come up with their next move they may

also ask you questions like do you know

what I mean where are you with me these

phrases are intended to make you feel

like you understand them and are on

their side despite the fact that they're

not telling you the truth

trouble speaking on the flip side

occasionally someone who's lying will

have trouble speaking at all due to

their body's physical reaction to stress

when you feel nervous your body often

reacts in ways that you have no control

over your nervous system can cause your

salivary glands to decrease production

during the time of stress which means

that the liars mouth is likely to dry


causing them to have difficulty speaking

you may also notice that they may

suddenly purse or point their lip

students they may also experience slips

of the tongue and speaking errors as the

panic signals in their brain transfer to

their body they may also change their

speech pattern altogether and adopt a

more formal way of speaking

due to their flight or fight mode being

active you may notice someone not using

contractions when they normally would

try asking a liar to repeat their story

but in the reverse order they likely

won't be able to if they told you a

story in chronological order ask what

they did before one of the things they

mentioned if they display signs of panic

are given in a consistent answer that's

a sure sign they're fired

aggressive behavior oftentimes Liars

will become hostile and defensive when

confronted especially when it becomes

clear that you're not buying their story

instead of admitting that they weren't

being truthful they'll double down and

try to blame the situation on you

pointing at you while they speak is a

physical way that they attempt to

intimidate and blame you for their

actions but where are people who

excessively point fingers as it's likely

they're not telling the truth

they may also raise their voice far

beyond their normal baseline this is an

attempt to place emphasis on their words

thus making them sound more believable

to the listener some people may just be

loud in general so you want to make sure

you're comparing their volume with how

they normally said if the tone of their

voice sounds angry arrogant or bullying

it's likely that they are trying to make

you fearful so that you're easier to

manipulate if this escalates to this

point it's usually a good idea to remove

yourself from the situation for your own

safety breathing changes because of the

stress responses a liar is experiencing

even their breathing can change Liars

will most often breathe oxygen through

their mouths

first their looks in order to increase

oxygen flow their voices may fade out or

trail off at the end of their sentences

as if they're trying to distance

themselves from their life they may also

speak in a shallow low voice rather than

being left because their nerves are

affecting their vocal cords their voice

may also sound raspy or change pitch

this is a huge red flag that they aren't

telling the truth and their body is

trying to stop them because of the

stress it's possible you may also notice

a slight shakiness in their voice from

their throat muscles contracting and

relaxing in these examples in previous

ones we talked about people's baseline

behavior one interesting trick is to

change the subject when you think

someone is lying if they seem visibly

relaxed and their demeanor changes

completely when they're speaking about

something else it's a great way to tell

that they were lying to you moments ago

if they were telling the truth they

wouldn't behave any differently was the

subject escape now that you're done with

this video we bet you feel like a master

investigator who could get to the bottom

of any situation dr. house once said

everybody lies so we're sure you'll have

plenty of opportunities to practice your

newly acquired detecting skills make
