Cross-sex and intrasexual theory of mind
Objects of Desire
675), we found consistent evidence that heightened sexual arousal increases sexual objectification in men. In Experiment 1, sexually aroused men showed a greater preference for women's sexual physical attributes (e.g. curvy, sexy) over psychological attributes (e.g. empathy, intelligence), as assessed by a novel State Sexual Objectification (SSO) task. Experiment 2 demonstrated that this effect occurred only for sexualized physical attributes rat…
How Do People Maintain Consensual Non-Monogamy? An International Development and Validation of the Multiple Relationships Maintenance Scale
Maintaining multiple intimate relationships entails some risks and complications beyond exclusive pair bonding (i.e., monogamy). Consensual non-monogamy (CNM; e.g., polyamory, swinging, or open relationships) allegedly reduces these risks and complications, but no one has tried to comprehensively document typical CNM risk management practices, nor analyzed the relationship outcomes of those who use these practices. We developed the Multiple Relat…
Income and Sex Moderate the Association Between Population Density and Reproduction
While previous studies guided by evolutionary life history theory have revealed several important socioecological moderators of the influence of population density (PD) on reproduction, absent is an understanding of how individual-level factors such as personal resources and sex differences might interact and play a role. Using data from a large sample of clients ( N = 4,432,440) of an online dating company spanning 317 states nested within 23 co…
The Dual Pathways Hypothesis of Incel Harm
Incels (involuntary celibates) are an online subculture of men who form their identity around a perceived inability to form sexual or romantic relationships. This community operates almost exclusively online, often serving as an outlet for misogynistic hostility. Concerns about violence from incels have positioned them as a growing (inter)national security threat. This study, the largest primary investigation of incel harmful attitudes and belief…
Hey ChatGPT, give me a title for a paper about degree apathy and student use of AI for assignment writing
ChatGPT could allow students to plagiarize the content of their coursework with little risk of detection. Little is known about undergraduate willingness to use AI tools. In this study, psychology undergraduates (N = 160) from the United Kingdom, indicated their willingness to use, and history of using, ChatGPT to write university assignments. Almost a third (32%) indicated that they would use such tools; 15% indicated that they had used them alr…
The harm hypothesis
Past research suggests that reactions to research on sex differences are often less positive when the findings put men in a better light than women, especially when the lead researcher is a man. The factors underlying this effect, however, are not yet fully understood. The present study aimed to provide the first experimental test of the hypothesis that the key variable is perceived harm to women. Participants (214 men and 219 women) evaluated a …

Strategies for becoming a more desirable mate
The current research aimed to study the strategies that people employ in order to become more desirable as mates in different cultural settings. More specifically, using a closed‐ended questionnaire on a sample of 7181 participants from 14 different countries, we identified 10 different strategies that people employ to become more appealing as mates. Participants indicated that they had more frequently used the “Enhance looks,” followed by the “S…
The Mating Psychology of Incels (Involuntary Celibates)
Mating represents a suite of fundamental adaptive problems for humans. Yet a community of men, called incels (involuntary celibates), forge their identity around their perceived inability to solve these problems. Many incels engage in misogynistic online hostility, and there are concerns about violence stemming from the community. Despite significant media speculation about the potential mating psychology of incels, this has yet to be formally in…
Reactions to research on sex differences
Two studies (total N = 778) looked at (1) how people react to research finding a sex difference depending on whether the research puts men or women in a better light and (2) how well people can predict the average man and average woman's reactions. Participants read a fictional popular‐science article about fictional research finding either a male‐ or a female‐favouring sex difference. The research was credited to either a male or a female lead r…
Being More Educated and Earning More Increases Romantic Interest
How humans choose their mates is a central feature of adult life and an area of considerable disagreement among relationship researchers. However, few studies have examined mate choice (instead of mate preferences) around the world, and fewer still have considered data from online dating services. Using data from more than 1.8 million online daters from 24 countries, we examined the role of sex and resource-acquisition ability (as indicated by le…

Sex Differences in Voyeuristic and Exhibitionistic Interests
Sociosexuality and sexual compulsivity predict sex differences in voyeuristic interest in the population. In this study, we used a sample of 1113 participants from the UK (46% men) to consider whether sociosexuality and sexual compulsivity interacted to explain these sex differences and whether this relationship extended to the related domain of exhibitionism. In doing so, we tested novel predictions derived from an evolutionary perspective which…
Reasons of Singles for Being Single
The current research aimed to examine the reasons people are single, that is, not in an intimate relationship, across eight different countries—Brazil, China, Czech Republic, Greece, Hungary, India, Japan, and the UK. We asked a large cross-cultural sample of single participants ( N = 6,822) to rate 92 different possible reasons for being single. These reasons were classified into 12 factors, including one’s perceived inability to find the right …
Reactions to male-favouring versus female-favouring sex differences
Two studies investigated (1) how people react to research describing a sex difference, depending on whether that difference favours males or females, and (2) how accurately people can predict how the average man and woman will react. In Study 1, Western participants (N = 492) viewed a fictional popular-science article describing either a male-favouring or a female-favouring sex difference (i.e., men/women draw better; women/men lie more). Both se…
A multi-country test of brief reappraisal interventions on emotions during the Covid-19 pandemic
Mate preference priorities in the East and West
OBJECTIVE: Mate choice involves trading-off several preferences. Research on this process tends to examine mate preference prioritization in homogenous samples using a small number of traits and thus provide little insight into whether prioritization patterns reflect a universal human nature. This study examined whether prioritization patterns, and their accompanying sex differences, are consistent across Eastern and Western cultures. METHOD: In …

Lowering Partner Standards in a Short-Term Mating Context
Sexual History and Present Attractiveness
The aim of this study was to explore how people's sexual history affects their attractiveness. Using an Internet survey, 188 participants rated their willingness to engage in a relationship with a hypothetical individual with a specified number of past sexual partners, ranging from 0 to 60+. The effect of past partner number was very large. Average willingness ratings initially rose as past partner number rose, but then fell dramatically. For sho…
Inside out
Prior research has shown that individuals engage in impression management online, both in a social networking context and when using avatars. However, avatar creation research often directly asks participants about their creation motivations or primes a specific social context. Such direct methodologies potentially lead to biases which may give a distorted picture of how ideal characteristics are reflected in avatars. Our research used a less exp…
