This is for entertainment, not a scientific measure of honesty. Who Lies More?
Psychologists and economists mostly test this with lab games, where people can lie about a coin flip or a die roll to win a small reward. A 2022 review in Current Opinion in Psychology concluded that men were often more dishonest in these studies, especially in competitive settings where a lie served their own interest. The same review found the differences were often small and changed from one situation to the next.
One of the largest pooled analyses, by Gerlach, Teodorescu and Hertwig in Psychological Bulletin (2019), covered 565 experiments with 44,050 choices. In those experiments 42% of men and 38% of women lied, a difference the Max Planck Institute's summary called not pronounced. How big the reward was, and whether the lie cost someone else, also mattered, and people lied more in lab studies than in field studies.
The kind of lie matters too. A 2018 meta-analysis of sender-receiver games by Valerio Capraro found men in these games more likely to tell lies that help themselves at someone else's cost, and also more likely to tell white lies that help someone else at their own cost. For lies that help both people, the results were inconclusive.
Lies also depend on who is listening. In a 1996 diary study by DePaulo and colleagues, people told relatively more self-serving lies to men and relatively more lies for the other person's benefit to women. A 2021 study by Jampol and Zayas found people gave underperforming women kinder but less truthful feedback than equally underperforming men.
Not every study finds a gap. When Jason Childs raised the stakes in a sender-receiver game, he found no difference in lying by gender. In an online dice study of 2,002 adults, men behaved dishonestly more often for small rewards, and the difference vanished when there was no reward.
Most of this research uses small rewards, student or online volunteers and self-reports, so it describes behaviour in tests, not any one person. This page measures nobody's honesty either. It is a paid poll for entertainment: every vote costs 99¢, only paid votes count, and the chart shows how paying voters split.

In many lab games, men lied slightly more often than women, especially in competitive set-ups where the lie paid off for them. The gap is small, some studies find none, and it changes with the stakes and the kind of lie, so it cannot tell you how honest any one person is.
The studies we checked do not settle it by gender. In a study of 128 couples by Tim Cole (2001), people reported telling more lies than they thought their partners told. How much they suspected a partner of lying was linked about twice as strongly to their own lying as to the partner's.
Both, mostly in small ways. A 2008 study of 80 online daters, from before the app era, compared their profiles with their real height, weight and age. Small inaccuracies were common: men's profiles were further off on height and women's on weight, and daters rated their photos as the least accurate part. In a Pew Research Center survey published in 2020, 71% of US online daters said it is very common for people on these platforms to lie about themselves to appear more desirable.
The studies on this page put the average at one or two lies a day, but the average hides a lopsided spread. In the 1996 diary study, students logged about two lies a day and community members about one. In a 2019 PLOS ONE survey of 194 adults, the average was 1.61 lies in the past 24 hours, 39% reported none, and the six most prolific liars told 38.5% of all the lies reported.
The research is mixed. In the 2019 survey above, 62.7% of the people who rated themselves good liars were men, but the study did not test whether they were right. A 2022 paper reporting two small face-to-face experiments found men's lies more convincing in the first, and no significant gender difference in how convincing people's lies were in the second.
No. WhoLiesMore is a paid opinion poll for entertainment. It is not a survey, voters choose to take part, and it does not measure anyone's honesty. The chart shows only how paying voters split.
Because only paid votes count. A vote joins the chart once the payment is confirmed, so the split shows what people were willing to pay to say. A vote costs 0.99 in US, Canadian or Australian dollars, pounds or euros, depending on where you connect from, and each vote counts once.
