Question

how can you tell if someone is lying to you?

Answer 1

1) Ans) Detecting high-stakes liars is often the work of the FBI, and they frequently look to facial expressions, body language, and verbal indicators as signals, or "tells," that someone is lying.

There are a number of facial expressions and associated reactions that could indicate someone is lying to you," he says. "Some are caused by nervousness, some by chemical reactions, and others by physical reactions."

To start, he says it's important to understand how the person in question normally acts.

It's best to observe someone for a while as you make small talk or ask innocuous questions, in order to see what his usual reactions are, including tics he may have," he says. "Then if he exhibits several lying indicators when you ask more pointed or suggestive questions, and these are not ones he previously performed, you can be confident that he's likely lying."

✓Watch their eyes

"This is a physiological reaction to him feeling uncomfortable or trapped by your questions that he doesn't want to answer," Bouton says. "It's a throwback to when people had to seek an escape route when they feared they were in a dangerous situation, such as facing a human or animal adversary."

✓Keep an eye out for rapid blinking

"A person will ordinarily blink about five or six times a minute, or once every 10 or 12 seconds," Bouton says. "When stressed — for instance, when someone knows he's lying — he may blink five or six times in rapid succession."

Bouton says exceptions to the usual blink rate mostly have to do with production of dopamine in the body

✓Count how long someone closes their eyes

Bouton says that when a person closes his eyes for a second or two, this may indicate he's lied to you, since this is a type of defense mechanism. Normally, he explains, a person will blink at a speed of 100 to 400 milliseconds, or 0.10 to 0.40 of a second.

✓Pay attention to the direction they look

"When you ask a normal, right-handed person about something he's supposed to have seen, if he looks upward and to his left, he's truly accessing his memory of the incident," Bouton says. "However, if he looks upward and to his right, he's accessing his imagination, and he's inventing an answer."

✓And keep an eye on what they do with their mouth

"A person's mouth will often go dry as she's lying," Bouton says. "She may do a sucking motion, pursing her lips, to try to overcome this."

When their lips are so tightened that they appear pinched and white, this can indicate lying.

✓Pay attention to which direction they shake their head

Often when people tell the truth they will nod their heads simultaneously in agreement with what they're saying. But if they shake their heads in disagreement with what they've said, their bodies are betraying their lie.
