Most people like to think they can “just tell” when someone is lying, but deception usually hides in plain sight, tucked inside everyday phrases. Liars rarely invent brand‑new language; they lean on familiar lines that sound honest on the surface but work hard behind the scenes. Here are 12 phrases that liars almost always use when they talk to you, and what those words are really trying to do.
1) “To be honest”
“To be honest” sounds like a promise of transparency, yet it often shows up right before a half‑truth. Experts on deception note that liars frequently preface a story with unprompted honesty signals to lower a listener’s guard, then slide into the part they want believed. Guidance on what to say when someone lies points out that this kind of framing is less about clarity and more about steering the conversation away from doubt.
In everyday life, someone might say, “To be honest, I was going to tell you,” after being caught hiding a message or expense. The phrase tries to rewrite the timeline, suggesting they were already on the path to honesty. For friends, partners, or coworkers, the stakes are high: if “to be honest” keeps popping up only when there is trouble, it is a cue to slow down, ask follow‑up questions, and look for whether actions match the sudden burst of “honesty.”
2) “Believe me”
“Believe me” is another classic move, especially when the story itself is shaky. Instead of offering evidence, the speaker leans on a direct appeal to the listener’s faith. Analysts of deceptive language note that liars use assurances of truthfulness to build false credibility, repeating them when they sense skepticism. In arguments, “Believe me” often arrives right after a contested detail, as if the phrase can patch over the weak spot.
When someone insists, “Believe me, that is exactly what happened,” but cannot answer basic questions, the phrase becomes a red flag. It shifts the burden onto the listener, implying that doubt is a personal failure rather than a reasonable response. Over time, this pattern can wear down confidence, especially in close relationships where trust is supposed to be earned through consistent behavior, not demanded on command.
3) “I don’t remember”
“I don’t remember” can be completely genuine, but in the hands of a liar it turns into a shield. Coverage of common lying phrases highlights how people use this line as a way to dodge specifics without committing to a full story. A person can deny knowledge of a text, a meeting, or a promise, while keeping enough wiggle room to adjust later if proof appears.
Visuals of a woman arguing with a friend on a couch from Prostock and another woman feeling annoyed over coffee from Mix capture how “I don’t remember” often lands in real life: one person frustrated, the other retreating behind selective amnesia. The stakes show up in accountability. If every tough question gets met with “I don’t remember,” it becomes nearly impossible to resolve conflicts, track commitments, or hold someone responsible for patterns of behavior.
4) “I’m not lying”
When someone blurts out “I’m not lying,” it can sound like a straightforward defense, but it often signals pressure. Deception research notes that liars repeat emphatic denials to overcompensate for guilt, especially when they feel the listener pulling away. Instead of calmly explaining, they double down on the label, trying to convince others, and sometimes themselves, that they are telling the truth.
Images credited as “Genuine truth doesn’t need theatrics” with “Credit” to “Getty Images” underline the point that honest people rarely need to announce their honesty. If a coworker or partner keeps insisting, “I’m not lying, why would I lie to you?” while avoiding direct answers, the performance itself becomes data. For anyone on the receiving end, the key is to focus on verifiable facts rather than the emotional volume of the denial.
5) “If you think about it”
“If you think about it” sounds like an invitation to reason, but liars often use it to massage the logic of a shaky story. They qualify their statements with extra framing, hoping the listener will adopt their angle instead of checking the details. Analysts of deceptive speech point out that this kind of preface softens inconsistencies and encourages selective interpretation, especially when the facts do not quite line up.
Someone might say, “If you think about it, I was technically home all night,” after slipping out for an hour they hope will not count. The phrase nudges the listener to accept a narrow definition that benefits the speaker. For stakeholders in negotiations, relationships, or workplace decisions, spotting this move matters, because it often signals that the person is trying to win an argument on a technicality rather than being straightforward.
6) “Trust me”
“Trust me” is one of the most common phrases linked to lying, precisely because it tries to shortcut verification. A breakdown of suspicious language notes that when someone leans on “Trust me” instead of proof, they are often trying to exploit relational bonds rather than earn confidence. One analysis of phrases that signal deception lists “Trust me” alongside other red flags, explaining that the more someone demands Trust, the less likely they are to build it naturally.
In practice, “Trust me, I know what I’m doing” can show up in money decisions, health choices, or workplace shortcuts. When the stakes are high, blind trust becomes risky. Honest people tend to welcome questions and offer receipts, screenshots, or clear timelines. Liars, on the other hand, lean harder on “Trust me” the more fragile their story becomes, hoping the phrase will close the conversation before anyone looks too closely.
7) “To the best of my knowledge”
“To the best of my knowledge” is a classic hedge. It sounds careful and responsible, but liars use it to create plausible deniability. If their claim is later exposed as false, they can fall back on the idea that they only spoke from limited awareness. Analysts of deceptive language describe this as building an escape hatch into the sentence, especially in situations where accuracy really matters.
In a meeting, someone might say, “To the best of my knowledge, the numbers are accurate,” even though they never checked the spreadsheet. The phrase shifts some responsibility away from them, making it harder to pin down accountability if the data turns out to be wrong. For teams, clients, or partners, that hedge can translate into real‑world costs, from bad forecasts to broken promises, all wrapped in a sentence that sounded careful at the time.
8) “As you said”
Liars often mirror the listener’s words, and “As you said” is a neat way to do it. By echoing the other person’s language, they create a sense of alignment, even when their own story is distorted. Analysts of lying behavior note that this kind of mirroring can make the listener feel validated, which lowers defenses and makes it easier for the liar to slip in their version of events.
For example, someone might respond, “As you said, we were both upset,” then quietly rewrite what happened in a way that minimizes their role. The phrase anchors their narrative to the listener’s earlier statement, making disagreement feel like self‑contradiction. In conflicts or negotiations, that subtle manipulation can tilt outcomes, because people are less likely to challenge a story that seems to start from their own words.
9) “That’s a good point, but…”
“That’s a good point, but…” looks polite on the surface, yet liars often use it as a pivot away from uncomfortable facts. They offer partial agreement to appear reasonable, then quickly steer the conversation toward a safer anecdote or side issue. Analysts of deceptive talk describe this as deflection through partial validation, a way to acknowledge criticism without actually addressing it.
Someone might say, “That’s a good point, but remember how busy I was?” and then launch into a long story that has little to do with the original question. The compliment disarms the listener, while the “but” clears space for a distraction. Over time, this pattern keeps real problems from being solved, because every legitimate concern gets buried under a new narrative instead of met with concrete answers or changed behavior.
10) “Honestly speaking”
“Honestly speaking” is another sincerity marker that liars lean on when they feel cornered. Repeated signals of honesty can actually be a tell that someone is worried about being believed. Analysts who study what to say when confronting deception note that genuine truth usually stands on its own, while liars add verbal highlighters like “honestly speaking” to counter perceived skepticism.
In a tense conversation, a person might say, “Honestly speaking, I would never do that,” even as evidence suggests otherwise. The phrase tries to reset the emotional tone, inviting the listener to feel guilty for doubting. For anyone evaluating the claim, it helps to separate the emotional packaging from the content. If “honestly speaking” shows up often, but the facts keep shifting, the pattern itself becomes a reason to question the story.
11) “It slipped my mind”
“It slipped my mind” sounds casual, almost harmless, which is exactly why liars like it. Instead of admitting they chose not to do something, they blame a fuzzy memory. A breakdown of deceptive phrases notes that selective amnesia is the best friend of someone trying to wiggle out of a tight corner, and that by claiming faulty memory, they avoid elaborating on invented or omitted details. One guide on how liars almost always use these 12 phrases even highlights “I Don’t Remember” as a close cousin of this move.
In practice, “It slipped my mind” might cover everything from missed deadlines to conveniently forgotten promises. The names Don, Remember, and Selective echo how memory gets framed in these discussions, turning deliberate choices into accidents. For colleagues, friends, or partners, the impact is real: repeated “slips” erode reliability, and over time, people start planning around the liar, assuming commitments are optional even when they sounded firm.
12) “Don’t you think?”
“Don’t you think?” is a subtle way for liars to recruit the listener into the lie. By ending with a rhetorical question, they fish for agreement and turn their statement into a shared opinion instead of a solo claim. Analysts of deceptive language note that this tactic helps liars feel safer, because if the listener nods along, challenging the story later feels like admitting their own misjudgment.
One discussion of what happens when you’re telling the truth but they call you a liar points out how “They” sometimes pressure others to agree, even when the facts are shaky. “Don’t you think?” works the same way, nudging people to co‑sign a version of events. For anyone listening, the safest move is to answer with specifics instead of a reflexive “yeah,” keeping space to evaluate the claim on evidence rather than social pressure.
