Abstract
Social-media platforms such as Facebook, Twitter, and Instagram are prominent communication channels for people worldwide. Although people generally seem to present a realistic image of themselves on these platforms, Back and colleagues (2010, p. 374) have called for further study of specific forms of impression management and individual differences in such behavior. Responding to this early call, we investigated gender differences in deceptive self-presentation on social-media platforms. We defined
The present research used truth-telling techniques (De Jong et al., 2012; John et al., 2012) to elicit self-reported disclosures on social-media platforms from more than 12,000 participants in 25 countries in order to address two questions. First, to what extent do men and women differ in deceptive self-presentation practices on social-media platforms in the domains of physical attractiveness and personal achievement? Mating theories suggest that these domains are differentially important for men and women (Buss, 2016; Gangestad, 1993). Deceptive self-presentation in these domains can be used with the goal of attracting the opposite gender or of signaling superiority to same-sex competitors (Tooke & Camire, 1991). Both goals could be pursued via social-media platforms. Second, this research examined how gender equality in society (i.e., equality in access to resources and opportunities irrespective of gender) affects deceptive self-presentation and how, if at all, gender differences in deceptive self-presentation depend on gender equality.
Gender Differences in Deceptive Self-Presentation
According to evolutionary theories, in primal environments, men most valued women’s physical attractiveness (a signal of health and fertility). Conversely, women most valued men’s ability to acquire resources (which increased the probability of offspring’s survival; Buss, 1989; Buss & Schmitt, 1993; Symons, 1979). According to
The societal contexts in which behavior takes place can moderate the expression of gender predispositions (Eagly & Wood, 1999). Gender equality in a society is a likely moderator of mating-associated behavior.
Statement of Relevance
Deceptive self-presentation on social-media platforms appears to be common. Yet it is largely unknown to what extent people engage in deceptive self-presentation in such mating-relevant domains as physical attractiveness and personal achievement and how this behavior differs between men and women. In this research, we asked more than 12,000 individuals across 25 countries to report on their deceptive behavior using a privacy-protection mechanism so they could give more honest answers. Using these cross-cultural data, we studied how differences in gender equality across countries could enhance or attenuate deceptive self-presentation. We found evidence that gender equality might attenuate deceptive behavior, at least for the domain of physical attractiveness. We also found that differences in deception rates between men and women were larger in gender-equal than in non-gender-equal countries, which is counterintuitive. This study sheds light on mating behavior online and contributes to the body of knowledge on gender theories.
The first two hypotheses specified main effects, respectively, for differences between genders (Hypothesis 1) and between societies that differ in gender equality (Hypothesis 2). How will gender and society interact, if at all, in their effects on deceptive self-presentation? There are two competing predictions, which we label, respectively, the
The attenuation hypothesis
An intuitive prediction is that gender differences in deceptive self-presentation should be smaller when men and women have more equal opportunities (Schmitt, 2005). For instance, in contrast with societies with low gender equality, in societies characterized by high gender equality, a partner’s ability to earn money is equally important for men and women (Zentner & Mitura, 2012). In gender-equal societies, women are less likely to see marriage as a source of financial security (Eagly & Wood, 1999; Isen & Stevenson, 2010), whereas men attach more importance to their appearance (Mellor et al., 2010). Possibly, the reduced pressure of gender-equal societies removes constraints for trade-offs primarily between beauty and resources, without other traits (e.g., kindness) being taken into consideration. Consequently, gender differences should be smaller in gender-equal societies.
The amplification hypothesis
In contrast to the aforementioned evidence, other mating-related gender differences have been found to be larger in more egalitarian societies. It is possible that the reduced pressure not only enables more flexibility in trading off traits but also increases the pool of relevant traits. For instance, if kindness instead of financial resources can match a man with a beautiful woman, then evolutionarily formed preferences for beautiful women can be successfully pursued by more men. In line with this reasoning, findings have shown that gender differences in sociosexual orientation and preference for attractive mates are larger with higher gender equality (Schmitt, 2005, 2015). Evolutionary-mismatch theories offer a potential explanation for such larger gender differences. These theories explain cross-cultural variations in gender differences as a function of the extent to which contemporary social environments mismatch ancestral environments in which gender differences were shaped (Li et al., 2018). Ancestral environments with higher mating freedom may mismatch contemporary less gender-equal societies more than contemporary more gender-equal societies (Crawford, 1998; Korotayev & Kazankov, 2003; Schmitt et al., 2008). Consequently, gender differences in deceptive self-presentation should be larger in societies with higher gender equality.
Empirical support for both the attenuation and amplification hypotheses in mating-related behavior does not yet favor one hypothesis over the other (Schmitt, 2015). Therefore, and before turning to the main study, we examined people’s lay beliefs about gender differences in deceptive self-presentation on social-media platforms, both for physical attractiveness and personal achievement.
Pilot Study: Lay Beliefs About Gender Differences
A sample of U.S. adult residents recruited from Amazon Mechanical Turk (MTurk) participated in an online study on lay beliefs about gender differences in deceptive self-presentation (

Cross-national sample
The data used in the main study were part of a larger project on cross-cultural differences and similarities designed by researchers from several European universities. Kantar Media group approved the study in accordance with international ethical standards of survey research. The company collected the data in 2016 through an online survey accessing participants from national panels in 25 countries. The full questionnaire, originally designed in English, was translated and back-translated into 19 languages and dialects (items with translations are in the Supplemental Material). In Australia, India, Singapore, South Africa, the United Kingdom, and the United States, the questionnaire was in English. The total sample comprised 12,257 adult participants (51% female) ranging in age from 18 to 90 years (
Measures
Eight items measured deceptive self-presentation on social-media platforms. Items were selected from an initial pool of 29 items through a series of pretests with three distinct samples (Pretest Sample 1: 51 culturally diverse university students, Pretest Sample 2: 510 culturally diverse university students, Pretest Sample 3: 1,005 Amazon MTurk recruits who were residents of the United States). Criteria for selection were item clarity, comprehensiveness, sensitivity, frequency of occurrence, domain coverage, and face validity. Details about questionnaire construction and the item-selection process are in the Supplemental Material. Responses were made on a binary scale (yes/no) to facilitate comprehension and implementation across countries. Binary response scales prevent the common extremity and midpoint biases in cross-cultural research and minimize interpretational differences between countries (Smith & Schwartz, 1997). Table 3 lists the items.
Items Used to Measure Deceptive Self-Presentation on Social-Media Platforms in the Main Study
Note: All items began with the stem “On [name of preferred social network], I have . . .”
Truth-telling mechanism
Answering questions about one’s deceptive self-presentation behavior is sensitive, which might promote participants to lie when they complete the survey items. Therefore, we used the
The RRT in our study used an electronic randomization device (an electronic spinner). Participants provided their answer to a question depending on one of two possible outcomes: The randomization device could instruct participants either to give a truthful response to a question or to give a forced “yes” answer regardless of what participants’ truthful response would be. The researcher does not know the outcomes of the randomization device but only the probability that the participant has to give a truthful response. Thus, the proportion of observed “yes” scores is equal to
Items administered with randomized response constituted a block in the questionnaire, which contained item blocks for unrelated other research. At the beginning of the block, participants read a definition of social-media platforms and indicated which ones they used (if any). If they listed multiple social-media platforms, participants indicated their preferred platform (on which they posted most often). Target questions were for the preferred social-media platform. Participants without a social-media account or who never shared content on their social-media profile were excluded. Instructions for the RRT are in the Supplemental Material.
Items for the physical-attractiveness and personal-achievement domains appeared consecutively on the screen in the order shown in Table 3. The instruction was, “Please indicate which of the behaviors below you have done at least once on your preferred social network.” Participants used the electronic spinner before answering each item on the screen. Items started with the stem “On [name of preferred social network] I have . . .” and the software piped in the name of the preferred social-media platform that the participant had indicated earlier in the questionnaire.
Gender equality
We obtained a nation-level measure of gender equality from Schwartz and Rubel-Lifschitz (2009). The measure is a standardized index of three indicators of gender equality: one indicator based on averages of women’s health, education, employment, and social equality; a second indicator based on differences between men and women in income, education, and representation in government; and a third indicator based on the average number of children in families (which is believed to limit women’s resources and to be negatively correlated with women’s career opportunities). We imputed the score for United Arab Emirates, as it was unavailable in the original publication, by taking the average (−2.25) of two available scores for countries in the region (Egypt = −1.74 and Yemen = −2.75). The average score of the gender-equality measure in our sample of 25 countries was 0.02 (
Control variables
We included the following control measures for participants: age, employment status (1 when employed more than 8 hr per week, 0 otherwise), relationship status (1 when in a committed relationship, 0 otherwise), education level (1 when higher education was completed, 0 otherwise), preferred social-media platform (1 when Facebook was the preferred social-media platform, 0 otherwise), and number of years using the preferred social-media platform. Facebook was the most popular platform at the time of data collection. For each of the 25 countries, we included a dummy variable indicating whether its per capita gross domestic product (GDP) was in the top 33%. Data were for 2015 in current U.S. dollars and were obtained from The World Bank (2020). Statistically controlling for this variable ensured that potential gender-equality effects were not due to GDP differences between countries.
Statistical analyses
We estimated a regression model that accounted for the specific characteristics of our data. That is, the data had a multilevel structure because individual participants in the survey (Level 1:

Descriptive statistics
Table 4 presents the prevalence of each of the deceptive self-presentation behaviors per country. These prevalence estimates were obtained by correcting the observed proportions (which contain added noise) for the randomized-response mechanism (Equation 1). The estimated proportion of participants who reported engaging in such behaviors ranged from a low of 5% (misrepresenting education [Item 5] or workplace [Item 7] in The Netherlands) to a high of 58% (using an outdated picture [Item 2] in China).
Prevalence of Deceptive Self-Presentation on Social-Media Platforms in the 25 Countries Analyzed in the Main Study
Note: See Table 3 for full text of Items 1 through 8.
The lowest level of deceptive self-presentation concerns the workplace (Item 7), for which around 12% of participants across all 25 countries reported that they deceived the employer they work for. The highest level of deceptive self-presentation globally—29%—concerns the use of an outdated picture in order to look better. Across the 25 countries, about 17% of participants in the sample reported performing each of the behaviors at least once.
To facilitate interpretation of the similarities and differences among countries, we plot average prevalence in Figure 1 across the behaviors in the two domains. In countries below the diagonal line, participants engaged in more deceptive self-presentation about physical attractiveness on social-media platforms, whereas in countries above the diagonal, deceptive self-presentation about personal achievement prevailed. The further a country is located from the diagonal, the higher the ratio of deception about physical attractiveness to deception about personal achievement. Most countries fell below the diagonal. The only two countries above the diagonal, where people practiced deception about personal achievement more than about physical attractiveness, were Australia and the United Kingdom. In The Netherlands (at the diagonal), the prevalence of deceptive self-presentation in both domains was approximately even (~7%).

Association between average deceptive self-presentation of physical attractiveness and personal achievement across 25 countries in the main study. Each domain score is an average across the prevalence rate of the four behaviors in that domain. Countries with gender equality above the mean are designated by light-gray circles, and countries with gender equality below the mean are designated by black squares. The diagonal is the equality line where prevalence of deceptive self-presentation in the two domains is the same. For explanations of the country codes, see Table 4.
Prevalence estimates for each gender in each of the two domains (averaged across the four items per domain) are shown in Table 5. On average, the prevalence of deceptive self-presentation about physical attractiveness on social-media platforms was higher among women than men (20% vs. 18%), whereas deceptive self-presentation about personal achievement on average was higher among men than women (14% vs. 10%). However, the gender gap varied substantially across countries and ranged from 0% to 12%.
Gender Equality and Estimated Prevalence of Deceptive Self-Presentation on Social-Media Platforms in the Main Study (Averaged Across the Four Items Within Each Domain)
Note:
If lay beliefs would be supported, gender differences should be larger for personal achievement than for physical attractiveness. In absolute values, this was indeed the case. That is, averaged across the countries, the gender gap in deceptive self-presentation about physical attractiveness on average was 2%, whereas it was 4% for deception about personal achievement (
Multilevel logistic RRT model
We then formally tested our hypotheses using the model from Equations 5 to 8. Because the model likelihood is too complex to evaluate in the presence of the randomized-response mechanism, we relied on Bayesian estimation routines. We used WinBUGS software (Version 1.4.3; Lunn et al., 2000) to estimate the posterior means of the model parameters (5,000 burn-in iterations and 15,000 iterations for inference). The annotated code used in the data analysis is in the Supplemental Material. Table 6 summarizes the results.
Results of Multilevel Logistic Randomized-Response-Technique Regression for Physical Attractiveness and Personal Achievement in the Main Study
Note:
In support of Hypothesis 1, results showed that men across the 25 countries in the sample reported engaging more in deceptive self-presentation about their personal achievement than women did, whereas women reported engaging more in deceptive self-presentation about their physical attractiveness than men did.
Hypothesis 2 was supported for the physical-attractiveness domain but, surprisingly, not for the personal-achievement domain. That is, deceptive self-presentation for physical attractiveness was lower overall in countries with more gender equality, as indicated by the negative effect (−0.18). Yet the main effect of gender equality on deceptive self-presentation about personal achievement was not statistically significant.
Turning to the control variables, we found that younger and employed participants reported more deceptive self-presentation in both domains compared with older participants and those who work less than 8 hr per week. Having a social-media account for a longer period of time was associated with more deceptive self-presentation in the domain of physical attractiveness but was not associated with deceptive self-presentation in the domain of personal achievement. Participants with a higher level of education reported less deceptive self-presentation for personal achievement but reported just as much deceptive self-presentation as participants without higher education for physical attractiveness. Participants who use Facebook as their main social-media platform reported as much deceptive self-presentation as did participants who prefer other platforms. Finally, participants in a committed relationship reported as much deceptive self-presentation as single participants did.
The statistically significant positive cross-level interaction between gender equality and gender indicates that the gender gap (female–male) was in fact larger—not smaller—in countries with higher gender equality, which supports the amplification hypothesis. Zooming in on the cross-level interaction between gender and gender equality in the domain of personal achievement, we found that whereas women’s deceptive self-presentation behavior dropped with higher levels of gender equality, men’s levels of deceptive self-presentation behavior about personal achievement actually remained unchanged.
Figure 2 presents the estimates of gender differences in prevalence of deceptive self-presentation in the two domains. To facilitate interpretation, we plot the predicted values of the model for gender-equality level at 1 standard deviation above and below the sample mean. At higher levels of gender equality and for physical attractiveness, there was a larger drop for men than for women, whereas for personal achievement, there was a drop for women but not for men.

Estimated gender differences in deceptive self-presentation on social-media platforms for countries low (−1
Taken together, the results provide support for Hypothesis 1—that women tend to deceive more about physical attractiveness on social-media platforms, whereas men tend to deceive more about personal achievement. The results partially support Hypothesis 2—that gender equality is associated with lower levels of deceptive self-presentation on social-media platforms. This is true for both genders in the domain of physical attractiveness and for women (but not for men) in the domain of personal achievement. In addition, the results partially support the evolutionary-mismatch perspective that in societal contexts with higher gender equality, primal gender dispositions become amplified, thereby widening the gender gap. Plots of all effect sizes are in the Supplemental Material.
Discussion
This study is the first to assess the universality of gender differences in deceptive self-presentation on social-media platforms across countries using a truth-telling mechanism to add to the veracity of participants’ responses. Data from 25 countries (
Across countries, we expected higher levels of countries’ gender equality to be associated with lower deceptive self-presentation in both domains (Hypothesis 2). Mating perspectives agree that gender differences in mating preferences, and thus in mating strategies, are contingent on the social context (Buss & Schmitt, 2019; Eagly & Wood, 2013). Our expectation was based on the idea that because gender equality is associated with more freedom in mating choices (Schmitt, 2005), the overall motivation to engage in deceptive self-presentation is reduced. Higher gender equality indeed led to lower deceptive self-presentation in the domain of physical appearance, but gender equality did not affect deceptive self-presentation in the domain of personal achievement. This is consistent with the notion that women’s preference for a partner with equal or higher access to resources remains even when women’s socioeconomic status increases (Townsend, 1989).
Further, the magnitude of gender differences in deceptive self-presentation varied with the level of gender equality in countries. Prior research has found that higher levels of gender equality and country development can sometimes amplify and sometimes attenuate gender differences in mating behavior and preferences (Schmitt, 2015). In our first study, people’s lay beliefs favored the attenuation hypothesis. In contrast, our large-scale cross-national study supported the amplification of gender differences because of higher levels of national gender equality. Specifically, our data indicated that with higher gender equality, the prevalence of gender-atypical deceptive self-presentation dropped more sharply than the prevalence of gender-typical deceptive self-presentation did. That is, the drop in deceptive self-presentation about physical attractiveness associated with gender equality was significantly larger for men than for women. The reverse pattern emerged for deceptive self-presentation about personal achievement: The drop in countries with high gender equality was large for women, but there was no significant drop for men.
The findings are consistent with the notion that gender equality does not make gender differences larger or smaller but that it facilitates the expression of ingrained gender predispositions (Schmitt et al., 2008; Schwartz & Rubel-Lifschitz, 2009). That is, whether gender differences are larger or smaller depends on whether lack of gender equality suppresses or enhances gender differences for a specific behavior. In the case of deceptive self-presentation on social-media platforms about one’s physical attractiveness and personal achievement, it appears that lack of gender equality enhances gender-atypical lies. In other words, a more restrictive mating environment forces people to engage in deceptive self-presentation even in the domains that are less central for them in mating competition from an evolutionary perspective, and gender gaps are attenuated. Further research could examine whether the same pattern holds for other deceptive self-presentation strategies (Tooke & Camire, 1991) specific to either intrasexual or intersexual competition, such as deceptive self-presentation about one’s promiscuity as opposed to one’s committed relationships.
It is important to note that higher gender equality was associated with lower deceptive self-presentation on social-media platforms in the domain of physical attractiveness for men and women worldwide, potentially decreasing the negative effects of social-media consumption on body satisfaction and body image (Fardouly & Vartanian, 2015). Furthermore, gender differences in the prevalence of deceptive self-presentation across the globe were statistically significant but not very large in an absolute sense (2% difference for physical attractiveness and 4% difference for personal achievement). This might be due to changes in labor division worldwide. Eagly and Wood (2013) proposed that because of higher involvement of women in the workforce, men in recent years have been placing more value on their mate’s financial prospects, whereas women find the mate’s physical appearance more important.
Our study addressed calls to examine how the Internet and online behavior in general shape social life and “may change our mating psychology in many ways” (Buss & Schmitt, 2019, p. 104). Future cross-national research could compare our estimates of deceptive self-presentation on social-media platforms with the deceptive self-presentation rates of comparable off-line behaviors, such as résumé tampering or the purchase of imitation brands. Higher deceptive self-presentation rates on online social-media platforms than in off-line behavior could support the prediction of matching theories that exposure to a larger number of successful and attractive peers on social-media platforms can decrease satisfaction with oneself (Li et al., 2018) and thereby stimulate a need to engage in deceptive self-presentation.
