People usually feel uncomfortable when they lie. They will show signs that something is being made up, whether they realize it or not. If you want to know how to catch a thief, pay attention to the physical, vocal, and emotional signs when he is talking.
Step
Method 1 of 4: Monitor Your Emotions
Step 1. Notice if you feel uncomfortable
If you're talking to someone and feel something isn't right, they may be lying.
Step 2. Learn the difference between a lie and the hard truth
If someone tells you bad or unpleasant news, they may appear to be lying, but are actually just nervous and uncomfortable saying it.
Step 3. Recognize natural tendencies
According to research conducted by the University of Massachusetts in 2002, women tend to lie to make people feel better, while men lie to make themselves feel better.
But remember that this is just a trend. Not that all women and men have this tendency. However, if a friend of yours seems to be lying when he makes comments about your new handbag, he or she may be doing it on purpose to make you feel good
Method 2 of 4: Listen Carefully
Step 1. Observe if he uses words like “you”, “we”, “us”, and “they” even though he could use “I” or other first person pronouns
A person who lies subconsciously tries to distance himself from his own words.
Step 2. Notice if he uses the phrase “to be honest” or something like that
Unless it's a phrase he uses often, it could be a sign that he's actually lying.
Step 3. Notice if there are any inconsistencies and contradictions in the story or the words
Determine if the story or words he is telling are natural and make sense. If he's telling stories in an unusual way, it could be a sign that he's lying.
Step 4. Notice if any of the details are redundant
Step 1. Watch the expression on his face when he says something that appears to be a lie
When he says "yes", he may shake his head, or vice versa. This involuntary movement can give a sign or indication of lying.
Step 2. Watch for fake smiles
Genuine and fake smiles look different from each other. Most people smile with their eyes, cheeks, and entire face. If someone is smiling a fake smile, he may be hiding something.
Step 3. Notice if he avoids eye contact with you frequently
Eye contact is difficult for a liar to maintain. A liar will react to this uncomfortable feeling by always looking you in the eye or always avoiding eye contact with you.
Method 4 of 4: Advanced Tips for Catching Liars
Step 1. Ask unexpected questions
Instead of following the liar's train of thought, think of a question he or she may not be prepared to answer.
For example, if someone says he lost your handbag but you think he's lying, try asking him to name the last few people who saw the bag (rather than asking where he saw it last). That could lead him to have to adjust his lie or confess
Step 2. Ask him to answer your question if he answers it by asking something else
Break the pattern he's trying to maintain and make him feel threatened to get caught to make him nervous.
Step 3. Pay attention to the tools he uses to lie
Someone is more likely to use a cellphone or email to lie. Meet him in person and reconfirm his story. Maybe he finally confessed or is still trying to make excuses.
