Uncovering a lie isn’t easy—many signs might hint someone isn’t telling the truth, but none can definitively prove they’re trying to hide a lie.
Spotting liars over the phone is even trickier since you miss out on the visible cues that appear in face-to-face talks. No blushing, no avoiding eye contact, no fidgeting with ears or nose—meaning the telling body language is completely absent when you can’t see who you’re talking to.
The best way to catch deception is to compare what you hear with the facts. Any deviation from the truth can signal dishonesty. These techniques can boost your lie-detection skills.
Be Skeptical!
Skepticism sends a message to the speaker that their claims aren’t taken at face value. When listeners show some doubt instead of instantly believing everything, liars often try even harder to convince them they’re telling the truth.
Truthful people stick to facts—they see the truth as the truth. So when listening on the phone, pay attention to whether the speaker shares facts or just tries to persuade you about them.
Use the Spotlight Effect!
Liars tend to believe others will spot their attempts to lie much sooner than they actually do. This is called the spotlight effect. When liars feel all eyes are on them, they think their deception is obvious—often revealing themselves through their behavior.

Watch for Throat Clearing!
Liars sometimes clear their throat when they’re about to lie in response to a question. If the person isn’t sick or showing cold symptoms, this can be a useful clue for the listener.
Avoid the “Maybe” Zone!
Yes-or-no questions deserve clear yes-or-no answers. If the speaker dodges direct answers and drifts into vaguer territory, it’s worth repeating the question. If you still don’t get a clear response, chances are the truth is being withheld.
Filler Words at the Start of Sentences
If you expect a yes or no and the answer starts with fillers like “Look, ...”, “How should I say...”, “Actually...”, “The thing is...”, “It’s hard to answer because...” and so on, it’s likely you’re not hearing the whole truth.

Filler Words Bring People Closer
The speaker tries to get closer to the listener to build trust and make sure the message truly reaches and is understood. Psychologically, words like “You know,...”, “Well,...” help create this trust. If someone uses these a lot, it’s a sign you might not be hearing the full truth but being gently misled while they earn your confidence.
More Signs That Point to Lying
- Liars answer questions you didn’t ask or respond to questions with questions.
- They mention exact times and dates to prove their point.
- They ask you to repeat the question or clarify what you mean.
- They describe details with fewer words and talk about events as if they weren’t personally involved.
