The internet has taught us many things but I thought this information was especially useful. It is useful for pretty much anyone and you can use it in any given situation to tell whether someone is truthful or telling a lie. It can thus help prevent you from becoming a victim of scams and other deceptions.
This is what you need to look out for:
Slip of the tongue
The brain is distracted because it is creating the next lie, or it is questioning the weakness of the one just told.
Hesitation before answering
This means the person is considering any flaws in the lie about to be given
Forced facial expressions such as smiling for a long period of time
Done in order to convince the interviewer of their lack of stress and fear.
Eyes that divert when the interviewer asks a difficult question
Indicates worry that the investigator is going to so through the lie.
Increased body activity, like fiddling with an object in front of them
This is emotion being turned into a physical need to relieve the stress of lying.
The tricky part in all this is just because someone exhibits one or more of these signs does not make them a liar.You have to compare the behavior they are showing with there natural behavior so results can be relative. Lie detecting experts say that a combination of body language and other cues must be used to make an educated guess on whether someone is lying or not.
