0:02 Someone close to you is lying right now.
0:04 Maybe it's about where they were last
0:06 night. Maybe it's about money. Maybe
0:09 it's something bigger. The FBI has spent
0:11 decades perfecting techniques to catch
0:13 liars in interrogation rooms. By the end
0:15 of this video, you'll know their most
0:16 powerful method so you can spot
0:18 deception before it costs you. I'm going
0:21 to show you nine techniques that FBI
0:23 agents use every single day. However,
0:26 the last one is so effective that once
0:28 you learn it, you'll never look at
0:30 conversations the same way again. And
0:32 the scary part, you've already fallen
0:33 for one of these lies today without
0:36 realizing it. So, let's begin. The
0:38 question that traps liars. Most people
0:40 ask the wrong questions when they
0:42 suspect a lie. If you ask something
0:44 broad like, "How was your night?" The
0:46 other person can dodge details easily.
0:48 They can give you a vague answer that
0:50 tells you nothing. If you ask, "You got
0:52 home early, right?" you're actually
0:55 giving them an easy escape route. They
0:58 can just say yes and move on. Therefore,
1:00 FBI agents use a different approach that
1:03 changes everything. They ask open
1:05 questions built on negative assumptions.
1:07 For example, instead of asking your
1:09 friend, "Did you go out last night?"
1:11 Say, "What kept you out so late last
1:13 night?" Instantly, you'll see their mind
1:15 scramble for details. Notice what
1:17 happens here. You're not asking if they
1:19 went out. You're assuming they did. This
1:21 forces the person to either admit the
1:24 truth or build a detailed lie. The more
1:26 details they give, the easier it becomes
1:28 to catch them slipping up later. Their
1:30 brain has to work harder to keep track
1:32 of the story. However, don't make it
1:34 sound like an attack. Keep your tone
1:37 casual and curious. Act like you're just
1:39 making conversation. You want them
1:41 talking freely, not shutting down and
1:43 getting defensive. The moment they feel
1:44 attacked, they'll stop talking
1:48 completely. The 5-second window. Right
1:50 after you ask a question, you have
1:52 exactly 5 seconds. This is your window
1:55 to catch the truth. In those 5 seconds,
1:57 watch everything. Their face, their
2:00 hands, their voice, their eyes. Every
2:03 tiny movement matters. After 5 seconds
2:06 pass, their brain has already adjusted.
2:07 They've had time to think and calculate
2:09 their response. They've had time to
2:12 build their defenses. Therefore, you
2:13 can't trust what happens after that
2:16 window closes. The honest reaction is
2:18 gone. But here's the key that most
2:20 people don't understand. One weird
2:22 behavior means nothing. Maybe they
2:24 always touch their nose when thinking.
2:27 Maybe looking away is just their habit.
2:29 Maybe they're naturally fidgety.
2:31 However, if you spot two or more
2:33 suspicious signs in those 5 seconds,
2:36 that's called a cluster. That cluster
2:38 tells you something is very wrong. Look
2:40 for things like contradictions in their
2:42 words, dodging your question completely,
2:44 touching their face repeatedly, or
2:46 breaking eye contact suddenly. When
2:48 these pile up in 5 seconds, you've
2:50 likely caught a lie. The person's body
2:52 is betraying them before their mind can
2:55 catch up. Reading the baseline. But
2:56 here's where most people mess up
2:59 completely. Before FBI agents ask the
3:02 hard questions, they do something smart.
3:05 They ask easy, neutral questions first.
3:06 Questions about the weather, about their
3:09 day, about anything harmless. Why?
3:11 Because they're studying how this person
3:13 acts when they're relaxed and telling
3:15 the truth. They watch tone of voice,
3:17 posture, hand movements, speech
3:19 patterns. They notice everything. This
3:21 is the baseline. It's like taking a
3:24 photograph of someone's normal behavior.
3:26 Once you know someone's baseline, any
3:28 change becomes obvious. If someone
3:30 usually looks you in the eye, but
3:31 suddenly stares at the floor when you
3:34 ask where they were, that shift matters.
3:36 That's not their normal. If their voice
3:38 usually sounds steady, but starts
3:39 cracking on certain topics, pay
3:41 attention. If they normally use their
3:43 hands when talking but suddenly go
3:46 completely still, something changed. The
3:48 baseline shows you what normal looks
3:51 like. Therefore, anything abnormal
3:53 becomes a red flag you can't miss.
3:54 Without knowing the baseline, you're
3:56 just guessing. With it, you're reading
4:00 them like a book. The double trap.
4:01 Here's a simple trick that catches liars
4:04 off guard every single time. Ask about
4:06 the same event twice, but change the
4:08 angle slightly. First time ask, "You
4:11 went to the gym yesterday, right?" They
4:13 say yes, they feel safe. Wait a few
4:16 minutes. Talk about something else. Let
4:18 them relax, but then circle back with,
4:19 "So, what exercises did you do at the
4:21 gym yesterday?" If they hesitate or
4:23 their answer doesn't match the first
4:26 response, you found an inconsistency.
4:27 Liars struggle to keep their story
4:30 straight across multiple questions. They
4:31 might remember the big lie, but forget
4:33 the small details they made up along the
4:35 way. Truth tellers don't have this
4:37 problem. If they actually went to the
4:38 gym, they'll tell you exactly what they
4:41 did without hesitation. However, a liar
4:44 has to invent details on the spot. They
4:46 have to remember what they already said.
4:48 They have to make sure the new details
4:50 fit the old ones. It's too much mental
4:53 work. Words that give them away. This
4:54 next trick is one even trained
4:57 interrogators rely on. When people lie,
4:59 they choose words differently. They
5:01 become more careful, more vague. You'll
5:04 hear phrases like, "I think, maybe,
5:07 probably, or I guess." These words give
5:09 them escape routes. If you challenge
5:11 them later, they can say, "Well, I
5:13 wasn't sure." They never committed to
5:15 anything concrete. However, this alone
5:17 doesn't prove lying. Some people just
5:18 speak this way naturally. They're
5:20 cautious in general. Therefore, watch
5:23 for when these vague words appear. If
5:25 they show up only during certain parts
5:27 of the story, especially the important
5:29 parts, that's your signal to dig deeper.
5:31 If someone is confident about the small
5:33 details but suddenly vague about the
5:36 crucial moment, something's wrong. Their
5:38 language is protecting them. The topic
5:41 dodge. We've all been lied to before. A
5:42 friend, a co-orker, even someone we
5:44 trusted. Watch what happens when you
5:46 touch a sensitive subject. If someone
5:48 suddenly tries changing the topic,
5:50 they're uncomfortable. Maybe they ask
5:51 you a question about something
5:53 completely different. Maybe they
5:55 remember something urgent they need to
5:57 tell you. Maybe they suddenly notice
5:59 something in the room. This dodge is a
6:00 defense mechanism. They're trying to
6:02 steer you away from dangerous ground
6:03 before they accidentally reveal
6:05 something they want hidden. The redirect
6:07 is their shield. If these tricks are
6:09 already blowing your mind, make sure you
6:11 hit like because we're only halfway
6:13 through the FBI's bestkept secrets.
6:16 Also, drop a comment below telling me
6:18 which technique surprised you most. Your
6:19 engagement helps more people learn how
6:21 to protect themselves. Now, let's keep
6:25 going. Breaking their focus. Lying takes
6:27 mental energy. Serious mental energy.
6:29 The person has to invent details,
6:30 remember what they already said, and
6:32 avoid contradicting themselves. Their
6:34 brain is working overtime just to keep
6:36 the story alive. Therefore, if you
6:38 interrupt them right in the middle of
6:40 their story with a completely different
6:42 question, you increase that mental load
6:46 even more. Try this. While they're
6:47 explaining something, suddenly ask,
6:49 "Wait, what were you doing right before
6:51 that happened?" This forces them to
6:53 reorganize their entire story in their
6:56 head. They rewind. They switch tracks.
6:58 And that's when cracks start to show.
7:00 Watch what happens next. If they seem
7:02 confused or if they restart with details
7:04 that don't match what they said before,
7:06 you've likely caught them in a lie. The
7:08 best moment to interrupt is when they're
7:10 deep in their narrative, fully focused
7:12 on keeping their story straight. After
7:13 the interruption, just say, "Okay,
7:16 sorry. Keep going." But then watch very
7:19 carefully how they continue. Do they
7:21 pick up exactly where they left off, or
7:23 do they restart from a different point?
7:25 Do the details still match?
7:28 The false detail test. This technique is
7:31 sneaky but incredibly powerful. Slip a
7:33 wrong detail into the conversation on
7:36 purpose. Say something like, "You said
7:38 it was Tuesday, but wasn't the store
7:40 closed that day?" Here's what happens
7:42 next. Someone telling the truth will
7:43 correct you immediately. They'll say,
7:46 "No, it was Wednesday." Or, "The store
7:48 was actually open." They're confident
7:51 because they know what really happened.
7:53 However, a liar often agrees with your
7:55 false detail. Why? Because they're
7:57 afraid that disagreeing with you might
8:00 make their whole story fall apart.
8:02 They'd rather accept your version than
8:04 risk looking suspicious by pushing back.
8:06 They think you know something they
8:08 don't. They think you're testing them,
8:10 so they go along with whatever you say.
8:13 This reveals the lie instantly. The
8:16 timeline trap. Ask for specific times.
8:18 What time did you leave? What time did
8:20 you arrive? People lying struggle with
8:21 timelines because they're making them up
8:24 as they go. Their answers often don't
8:26 make sense mathematically. If they say
8:29 they left at 8:00, arrived at 8:30, but
8:31 the drive actually takes an hour,
8:33 something's wrong. The math doesn't add
8:35 up. If they claim they were somewhere
8:38 for 20 minutes, but describe activities
8:40 that would take an hour, the timeline
8:43 breaks. Timelines don't lie. Numbers
8:46 don't lie. Therefore, when someone's
8:48 timeline has holes, their story probably
8:51 does, too. Truth always fits reality.
8:55 Lies never do. The final piece. Now,
8:57 here's what most people miss completely.
8:59 These techniques work best when you
9:01 combine them. Use the baseline to spot
9:04 changes. Use the 5-second rule to catch
9:07 clusters of deception. Use timeline
9:09 questions and double traps together.
9:11 Stack them. Layer them. However, there's
9:13 one more thing that matters more than
9:15 all of these techniques combined. Your
9:17 instinct. Deep down, you usually know
9:20 when something feels off. These FBI
9:21 techniques just give you proof of what
9:24 your gut already suspected. Trust that
9:26 feeling. When multiple techniques point
9:28 to the same conclusion, you're not being
9:30 paranoid. You're being smart. You're
9:32 being observant. Remember that person
9:34 who was lying to you at the start of
9:36 this video? Now you know exactly how to
9:38 catch them. The truth always leaves
9:40 fingerprints. Thanks for watching and
