Everyone has that one friend. You know the one—the guy who exaggerates his bench press by fifty pounds or the woman who insists she’s "five minutes away" when she’s actually still in the shower. It’s a classic debate. If you ask a group of people who lies more male or female, you’ll get a split room. Men often get the reputation for being the "big" liars, while women are sometimes pegged as the masters of the "polite" lie. But here’s the thing: most of what we think we know about gender and lying is based on sitcom tropes rather than actual psychological data.
Lying is human. We all do it.
The science of deception is messy because, honestly, people aren't always truthful about how much they lie when researchers ask them. It’s a bit of a paradox. Yet, over the last few decades, psychologists like Bella DePaulo and Robert Feldman have spent countless hours tracking thousands of interactions to figure out if one gender really holds the crown for dishonesty.
The Frequency Myth: Breaking Down the Numbers
If you’re looking for a simple "men lie 40% more" statistic, you’re going to be disappointed. Most major studies, including a landmark meta-analysis published in Psychological Bulletin, suggest that the total volume of lies told by men and women is remarkably similar. On average, most people tell about one to two lies per day.
It’s not a contest of quantity. It’s a matter of motivation.
Men tend to lie for self-enhancement. It’s about looking better, stronger, or more successful than they actually are. Think of it as "proactive" lying. A man might lie about his salary in a bar or inflate his role in a project at work to command respect. It’s ego-driven. On the flip side, women’s lies are frequently "altruistic" or "social" lies. These are the "I love your hair" or "No, you didn't sound stupid at all" comments. Women are socialized to prioritize harmony and avoid hurting feelings, which leads to a higher frequency of what we call "white lies."
Does a white lie count as much as a boastful lie? That’s where the debate on who lies more male or female gets complicated. If you count every "I’m fine" when someone is clearly not fine, women might take the lead. If you count every "I was the MVP of my high school team" when they actually sat on the bench, men might pull ahead.
Why Men Lie: The Power Play
Evolutionary psychology offers some clues here. Historically, men have had to compete for status and resources. In that high-stakes environment, looking like a "winner" matters.
A study conducted at the University of Massachusetts found that in a ten-minute conversation with a stranger, men didn't necessarily lie more than women, but their lies were distinctively different. They were more likely to lie to make themselves appear more competent. It’s a defense mechanism. If a man feels his status is threatened, the impulse to "pad the truth" kicks in hard.

There's also the "lie of omission." Men are statistically more likely to keep secrets by simply not mentioning things. It’s not a direct fabrication, but it’s still a form of deception. They might leave out the fact that they ran into an ex or that they lost money on a bad investment. It’s about maintaining a specific image of control.
The Social Glue: Why Women Lie
Women are often the emotional architects of a social group. Because of this, their deceptions are frequently geared toward protecting others. Bella DePaulo, a leading expert on the psychology of lying, found that women tell more "kind-hearted" lies than men.
These aren't necessarily "bad" lies in the traditional sense. They are the lubricants of social interaction. If a woman tells her friend that her wedding dress looks stunning—even if she thinks the lace is a bit much—she’s prioritizing the relationship over the objective truth.
However, this doesn't mean women are "purer" liars. Women also lie to avoid conflict. If a woman tells her partner she’s not mad just to avoid a three-hour argument, that’s a lie. It’s a strategic choice to preserve peace, even if it creates a layer of dishonesty in the relationship. Interestingly, research suggests that women are often more bothered by their own lies than men are. They carry a higher "guilt load" for deception, likely because it conflicts with the social expectation of being "nurturing" and "honest."
Who Lies More Male or Female in Romantic Relationships?
This is where the stakes get high. In the context of dating and long-term partnerships, the "who lies more" question takes on a whole new meaning.
In the early stages of dating, both genders lie like crazy. It’s basically an arms race of deception. Men lie about their height, their income, and their commitment levels. Women lie about their age, their interests (suddenly she loves golf!), and their physical appearance (thanks, filters).
But as the relationship progresses, the lies change.
- Infidelity: Research into cheating is notoriously difficult because people lie about lying. However, data from the General Social Survey (GSS) has historically shown that men are more likely to report being unfaithful. That gap is closing, though. Younger generations of women are reporting infidelity at rates much closer to their male counterparts.
- Financial Infidelity: This is a big one. Both genders are equally guilty of "hiding" purchases or lying about debt. A man might hide a crypto loss; a woman might hide a closet full of expensive shoes. It’s the same behavior with different targets.
- Emotional Honesty: Women are generally more "truthful" about their feelings, whereas men often lie by saying they are "fine" or "just tired." This emotional masking is a form of lying that often goes unrecognized but can be deeply damaging to intimacy.
The Detection Gap: Can You Tell?
Here’s a kicker: people are generally terrible at spotting lies. We’re about as good as a coin flip—roughly 54% accuracy.

There is a common belief that women have "intuition" and can spot a lie better than men. There is some truth to this, but it’s not magic. Research suggests that women are more attuned to non-verbal cues. They notice the micro-expressions, the tone shifts, and the fidgeting. Because women are often socialized to be more observant of emotional states, they might pick up on the feeling that something is wrong before a man does.
Men, on the other hand, tend to focus more on the logic of the story. If the facts don't line up, they smell a rat. Neither gender is a human polygraph, but they tend to use different "lenses" to detect deception.
Does Power Change the Equation?
When we talk about who lies more male or female, we have to talk about power.
Power is the great equalizer of dishonesty. Studies show that people in positions of high power—regardless of their gender—lie more frequently and feel less guilt about it. When you’re at the top, you feel more entitled to "bend" the rules. In the corporate world, a female CEO and a male CEO are likely to utilize deception at very similar rates to protect the company or their own interests.
The gender differences we see in everyday life often evaporate when you look at high-stakes professional environments. In those spaces, the pressure to succeed overrides the social conditioning that usually dictates how men and women lie.
The Impact of Modern Technology
Social media has completely flipped the script on lying. We now live in an era of "curated reality."
Is a filtered photo a lie? Is a LinkedIn post that exaggerates your contribution to a project a lie?
Women tend to engage more in the visual deception of social media—shaping an image of a "perfect" life, home, and body. Men tend to engage in "success" deception—posting about wins, "the grind," and material wealth. Again, the frequency is similar, but the flavor is different. The digital world has made it easier for everyone to lie more frequently because there’s no immediate "tell" like a shaky voice or avoidant eye contact.

Actionable Insights: Navigating the Truth
Knowing the patterns is one thing, but how do you use this information? Understanding the motivations behind the lies can actually improve your relationships.
1. Look for the "Why" Not the "What"
If you catch a man lying about a minor achievement, recognize that it’s likely coming from a place of insecurity rather than a desire to manipulate you. If you catch a woman lying to "protect your feelings," recognize that she values the relationship's peace over the cold hard truth.
2. Watch for Shifts in Baseline
Don't look for "eye contact" as a sign of lying; that’s a myth. Professional liars look you right in the eye. Instead, look for shifts in how someone usually acts. If a normally talkative person becomes suddenly brief, or a calm person starts fidgeting, that’s your red flag.
3. Foster a "Low-Stakes" Truth Environment
People lie because they fear the consequences of the truth. If you want more honesty in your life, you have to make the truth "safe." This means reacting calmly when someone admits a mistake or a flaw.
4. Check Your Own Bias
We often judge the lies of the opposite gender more harshly than our own. We excuse our "white lies" as being kind, but judge others' "white lies" as being fake. Realizing that everyone is just trying to navigate social pressures can make you a more empathetic (and harder to fool) person.
At the end of the day, the question of who lies more male or female is less important than why we lie. We lie to be loved, to be respected, and to belong. Whether it's a man exaggerating his past or a woman hiding her present, the root cause is often a very human fear of being "not enough." Understanding that might not stop the lies, but it certainly helps you see through them.
The data is clear: no gender has a monopoly on the truth. We’re all just doing our best to look good while hiding the messy bits of being human.
